PIC16F54-E/SS - 8-Bit Flash MCU, 18-Pin SSOP | Microchip

The Microchip Technology PIC16F54-E/SS is a flash-programmable 8-bit CMOS microcontroller with 0.77 KB program memory, 25 bytes of RAM, 12 general-purpose I/O pins, and an 18-pin SSOP package. It executes a 12-bit instruction set containing 33 single-word instructions with a stated 200 ns instruction execution time. The E/SS ordering identifies the extended-temperature SSOP-18 device variant represented by the verified Microchip and Mouser product records. A PIC16F54 microcontroller belongs to the PIC16 family of 8-bit RISC microcontrollers. Within the semiconductor hierarchy, it is a microcontroller, embedded controller, and programmable logic device used to execute firmware that senses inputs, controls outputs, and coordinates digital functions. Its compact architecture is aimed at cost-sensitive embedded products where a small instruction set, straightforward peripherals, and a modest memory footprint are more useful than high computational throughput. The verified features emphasize simplicity rather than benchmark performance. Program storage is 0.77 KB, while 25 bytes of RAM provide working memory. Twelve I/O pins allow the device to interface with switches, indicators, sensors, and external logic. Its 33-instruction set and 200 ns execution figure make it useful for straightforward control loops, while flash memory permits repeated programming and firmware updates. The target is offered in the compact SSOP-18 surface-mount package for space-conscious assemblies. The PIC16F5X architecture uses 12-bit-wide instructions designed for code efficiency within an 8-bit device class. The manufacturer describes the PIC16F54 as combining a 200 ns instruction-execution capability with only 33 single-word instructions. This compact instruction repertoire simplifies firmware development for simple sequencing and control tasks. Because available memory is limited, effective designs should minimize library overhead, avoid unnecessary buffering, and use compact control logic. Typical uses include appliance control, small industrial automation modules, simple sensor interfaces, automotive accessories, and entry-level consumer products. The 12 available I/O pins make the device appropriate for compact products that require discrete digital control rather than high-speed communications or a large user interface. The extended-temperature ordering also makes it a candidate for industrial and automotive environments, subject to the complete manufacturer specifications and system qualification. PCB design should preserve the exact SSOP-18 footprint and follow the manufacturer's pinout and recommended decoupling guidance. Because programming, configuration, and brownout behavior are sensitive to power and clock conditions, designers should consult the PIC16F54 datasheet before fixing supply voltage, decoupling capacitance, oscillator configuration, and programming connections. A complete SSOP-18 land pattern and all 18 pin assignments were not included in the retrieved source excerpts, so they are not asserted here. This product record combines the verified manufacturer and distributor information with engineering-focused selection guidance, package context, and explicit data-gap handling. It also distinguishes confirmed PIC16F54 characteristics from unverified operating limits, avoiding invented electrical values. The resulting PIC16F54-E/SS reference is intended to help engineers identify the correct flash-memory 8-bit MCU and evaluate same-package PIC16F54 alternatives before starting a PCB or firmware design.

PIC16F54-I/P - 8-Bit 20MHz 768B Flash MCU 18-PDIP | Microchip
PIC16F54-I/P

PIC16F54-I/P - 8-Bit 20MHz 768B Flash MCU 18-PDIP | Microchip

The Microchip Technology PIC16F54-I/P is a 8-bit CMOS Flash-based microcontroller from the PIC16F5x family that delivers up to 20 MHz instruction execution (200 ns per instruction cycle) in a through-hole 18-pin PDIP package. Key headline parameters: 768 bytes of Flash program memory (512 x 12 words), 25 bytes of SRAM data memory, and 12 digital I/O pins, supported by a wide 2.0 V to 5.5 V operating voltage range. It is industrial-temperature qualified (-40 °C to +85 °C) under the "-I" suffix and ships in a RoHS-compliant PDIP-18 through-hole package. A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (Flash/ROM for program code and SRAM for data), and programmable I/O peripherals onto one die. The PIC16F54 belongs to the PIC16 family, which sits inside Microchip's 8-bit PICmicro architecture hierarchy: PIC10/PIC12/PIC16/PIC18 (8-bit) -> PIC24/dsPIC (16-bit) -> PIC32 (32-bit). Within the PIC16 sub-family, the F5x series is the lowest-cost entry-level group, optimized for simple logic replacement, sensor conditioning, and appliance control rather than communication-rich applications. Key features that differentiate this part include: 33 single-word instructions (with all branches executing in two cycles and all other instructions in one cycle), a two-level hardware stack, direct/indirect/relative addressing modes, an internal 4 MHz RC oscillator (calibrated to within ±1 % by Microchip), and a 4-channel 8-bit A/D converter (PIC16F57/59 variants only — the PIC16F54 does not include ADC). The wide 2.0 V to 5.5 V Vdd range enables direct battery operation from two alkaline cells, and the low-power CMOS design keeps operating current in the low milliamp range at full clock speed. Architecturally, the device uses a Harvard-style bus (separate program and data paths) with a 12-bit-wide instruction word, giving a typical 2:1 code density advantage over competing 8-bit CISC architectures. The watchdog timer with on-chip RC oscillator, programmable code protection, and power-on reset (POR) provide autonomous fault recovery without external components. Three I/O ports (RA0-RA3, RB0-RB7, RC0-RC7 — though on the 18-pin PIC16F54 only RA0-RA3 and RB0-RB7 are bonded out) expose up to 12 general-purpose digital lines. Typical applications for the PIC16F54-I/P include appliance controls (washing-machine front panels, microwave keypads), LED driving and chase-light controllers, remote-control transmitter ICs, simple battery-powered sensor interfaces, automotive body-electronics subsystems (mirror control, simple HVAC flaps, courtesy lamps), and industrial logic-replacement modules. The wide Vdd tolerance and minimal external BOM make it ideal as a "glue logic" replacement for discrete 74HC gates in space-constrained designs. When designing with this part, note that the PIC16F5x family is OTP-style Flash (single-bank, no self-programming), uses a 12-bit instruction word (incompatible with newer 14-bit PIC16 midrange cores), and has only a two-level hardware call stack — recursion is not supported. Designers should use the MPLAB X IDE with the XC8 compiler in "pic16f54" mode and select the appropriate programmer (PICkit 3/4 or ICD) configured for the 18-pin PDIP.

It is supplied in an 18-pin SOIC package and provides 12 I/O ports for compact embedded-control designs. A microcontroller is a programmable semiconductor that combines a processor core, memory, I/O, and control peripherals on one integrated circuit. The PIC16F54 belongs to the PIC16 family of 8-bit microcontrollers and uses the PIC16RISC architecture. Its compact instruction set is intended for cost-sensitive appliances, industrial controls, security equipment, and simple embedded products that need deterministic control rather than a high-performance processor or large memory capacity. The verified product information identifies 33 single-word instructions and 200 ns instruction execution. The device uses flash-based program memory, allowing firmware to be programmed and updated through the manufacturer-supported programming process. Its 768-byte flash area is organized as 512 words by 12 bits, while the 25-byte RAM provides working storage for control logic, state variables, and small data buffers. PIC16F54-I/SO combines a 20 MHz maximum clock with 12 general-purpose I/O ports in an 18-SOIC surface-mount package. The 12 I/O pins make the device suitable for simple control panels, digital inputs, relay or switch interfaces, sensor conditioning, and sequential automation functions. Because the verified data does not provide every peripheral detail, designers should consult the manufacturer datasheet for exact port direction, reset behavior, oscillator options, and electrical limits. Typical applications include home appliances, security systems, motor-control interfaces, industrial automation, and consumer entry-level products. The 18-pin package is easy to route on a conventional through-hole-style or mixed-technology PCB, although designers should confirm land-pattern dimensions and pin functions before layout release. When replacing a device, verify the exact package suffix, operating-temperature grade, flash memory, I/O count, and clock requirement. Use the manufacturer datasheet as the authoritative source for pinout, electrical characteristics, programming, and application limits. This page combines verified distributor specifications, official Microchip product information, application guidance, and replacement analysis. It distinguishes confirmed data from parameters that still require datasheet review rather than inventing missing electrical or mechanical values.

The Microchip Technology PIC16F54-I/SS is a 8-bit flash-based microcontroller in the PIC16F5x family, delivering 20 MHz instruction execution (200 ns instruction cycle) with 768 bytes (512 x 12) of program flash and 25 bytes of RAM, housed in a 20-pin SSOP package. It provides 12 digital I/O pins suitable for low-cost general-purpose control. A microcontroller (MCU) is an integrated circuit that combines a CPU core, program memory, RAM, and peripheral interfaces on a single chip. The PIC16F54 belongs to the PIC16 family, which sits within the 8-bit RISC microcontroller segment of the broader embedded MCU hierarchy (8-bit MCU -> microcontroller -> embedded processor -> semiconductor). It is one of the simplest PIC16 devices, designed as a low-pin-count successor to legacy EPROM-based PIC16C5x parts. Key features include 33 single-word instructions for compact code, 12-bit-wide opcodes yielding 2:1 code compression over 8-bit instruction MCUs, and a wide 2.0V to 5.5V supply range with 4.5V to 5.5V typical operation. The 8-bit timer/counter (TMR0) with programmable prescaler, watchdog timer with on-chip RC oscillator, power-on reset, and brown-out detection support robust field deployment. In-circuit serial programming (ICSP) is supported via RB6/RB7 for low-cost field updates. Architecturally, the PIC16F54 uses a Harvard RISC core with separate program and data buses. Its 12-bit instruction word and 8-bit data path deliver a predictable execution model in which every instruction takes one instruction cycle except branches. The on-chip RC oscillator eliminates the need for external clock components in cost-sensitive designs. Power management is implemented through the SLEEP instruction with wake-up on pin change, and the MCLR reset path. Typical applications include consumer appliance control, LED lighting drivers, automotive body electronics (with AEC-Q100-qualified PIC16F54T variants), battery chargers, and industrial sensor interfaces where small code footprint and low BOM cost dominate. The 200 ns instruction execution supports real-time control loops in motor and lighting subsystems. When designing with this MCU, allocate I/O carefully: pins GP0-GP5 (port A) and GP0-GP7 (port B) share functions with ICSP, timers, and interrupts. Place a 0.1 uF decoupling capacitor adjacent to VDD and a 10 kohm pull-up on MCLR for reliable reset. Code protection must be enabled for production units to prevent unauthorized firmware readback. This page synthesizes distributor stock and pricing, drop-in pin-compatible alternatives, and practical design notes that are not found in the manufacturer datasheet alone, enabling engineers to evaluate the PIC16F54-I/SS for cost-sensitive 8-bit designs in a single view.

PIC16F54T-E/SO

PIC16F54T-E/SO - 8-bit Flash MCU, 768B, 20MHz, SOIC-18 | Microchip

The Microchip Technology PIC16F54T-E/SO is an 8-bit Flash-based CMOS microcontroller (MCU) from the PIC16 family, featuring a 12-bit instruction set (RISC architecture), 768 bytes of program memory, and a 20 MHz maximum clock speed. It is housed in an 18-pin SOIC (Small Outline Integrated Circuit) wide-body package delivered on Tape and Reel, with -40C to +125C extended automotive temperature grade and a 4.5V to 5.5V supply voltage range. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, RAM, program memory (Flash/ROM/EPROM), I/O ports, and peripherals onto one die. Within the broader taxonomy, the PIC16F54 sits as: PIC16F54 -> PIC16 family -> 8-bit MCU -> microcontroller -> embedded processor -> semiconductor. RISC (Reduced Instruction Set Computer) MCUs like this one execute each instruction in a small fixed number of clock cycles (often one per instruction cycle), enabling predictable real-time behavior at lower clock frequencies than complex CISC designs. The 33 single-word instruction set makes assembly programming straightforward and keeps the learning curve shallow for embedded beginners. Key features include 25 bytes of RAM, 12 GPIO pins, a hardware 8-bit timer (TMR0), a watchdog timer for fault recovery, an internal RC oscillator reducing external component count, and Flash memory that supports in-circuit serial programming (ICSP) for field upgrades. The device supports 200 ns instruction execution, enabling deterministic control loops. The PIC16F54 architecture uses a Harvard-style memory layout with separate program and data buses, allowing instruction fetch and data access to occur in the same cycle. Flash memory is one-time field-updatable via ICSP, an advantage over older OTP (one-time programmable) PIC12/PIC16 designs. The integrated brown-out reset (BOR) and power-on reset (POR) circuitry simplify the external reset network. Typical applications include automotive body controllers and sensor interfaces, industrial appliance control (relays, solenoids, valve drivers), low-cost consumer electronics, LED lighting controllers, battery chargers, and remote-control transmitter ICs. The automotive temperature grade (-40C to +125C) makes it appropriate for under-hood and dashboard environments. Designers should note that only 12 GPIO are available, so I/O expansion via I/O expanders or multiplexing is required for applications exceeding that count. The 768-byte program memory supports approximately 500 instructions, which constrains the firmware size.

PIC16F54T-E/SS

PIC16F54T-E/SS - 8-Bit PIC MCU, 768B Flash, 20MHz | Microchip

The Microchip Technology PIC16F54T-E/SS is an 8-bit Flash-based CMOS microcontroller from the PIC16F5X family, delivering 200 ns instruction execution in a 20-pin SSOP package. The part integrates 768 bytes of program memory (Flash), 25 bytes of RAM, 12 I/O pins, and a 20 MHz internal oscillator, and operates from a 2.5V/3.3V/5V supply range. The 'T' suffix denotes Tape & Reel packaging, 'E' indicates the Extended (-40C to +125C) temperature grade, and '/SS' specifies the SSOP-20 package. Background: An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, volatile data memory, and programmable I/O peripherals. The PIC16F5X family sits within Microchip's original PICmicro architecture hierarchy - 8-bit MCU -> mid-range MCU -> PIC16 family - targeting low-pin-count, low-cost embedded control. With only 33 single-word instructions, the PIC16F54 is one of the simplest PICmicro devices, optimized for cost-sensitive, deterministic control loops where code size and BOM cost matter more than peripheral richness. Key features include: 12 I/O ports with independent direction control, on-chip Power-on Reset (POR), a Watchdog Timer (WDT) with its own on-chip RC oscillator for reliable recovery, a 4-bit prescaler shared between WDT and Timer0, and in-circuit serial programming (ICSP) via two pins. The wide 2.0V-5.5V supply range supports both 3.3V and 5V rails. Code protection prevents unauthorized read-out of on-chip Flash. Architecturally, the device uses a 12-bit-wide instruction word with a 2:1 code compression advantage versus competitive 8-bit MCUs, allowing 768 bytes of program memory to hold approximately 512 single-word instructions. Harvard architecture separates program and data buses, and most instructions execute in a single 200 ns cycle (5 MHz instruction rate at 20 MHz oscillator), simplifying real-time control math. The Extended temperature grade makes the 'E' variant suitable for automotive and industrial environments. Typical applications include automotive body controllers, industrial sensor interfaces, low-end appliance control, LED driver sequencers, and battery-powered IoT edge nodes where deterministic timing and small footprint are priorities. The 12 I/O pins comfortably drive multiple switches, relays, or PWM outputs via firmware bit-banging. Design consideration: Place a 0.1uF decoupling capacitor close to VDD, and follow Microchip's recommended ICSP layout (ICSPCLK/ICSPDAT lines) if in-field firmware updates are required. The Watchdog Timer should be enabled in any unattended embedded application to recover from firmware lock-ups.

PIC16F54T-I/SS

PIC16F54T-I/SS - 20MHz 8-Bit 768B Flash MCU SSOP-20 | Microchip

The Microchip Technology PIC16F54T-I/SS is an 8-bit flash-based CMOS microcontroller from the PIC16F5X family, delivering 20 MIPS performance through a 200 ns instruction cycle in a 20-pin SSOP package. It integrates 768 bytes (512 x 12) of Flash program memory and 25 bytes of RAM, with 12 digital I/O pins arranged across PORTA and PORTB. The device operates from 2.0 V to 5.5 V across the industrial temperature range (-40C to +85C). A microcontroller (MCU) is a single-chip computer containing a processor core, program memory, working RAM, and peripheral interfaces. The 8-bit class is the workhorse of embedded control: inexpensive, deterministic, low-power, and easy to program. The PIC16F54 belongs to the Microchip mid-range baseline architecture, which sits below the enhanced mid-range (PIC16F1xxx) and PIC18 families in complexity but excels in code density and interrupt-free deterministic execution, making it ideal for cost-sensitive volume production. Key features of the PIC16F54 include 33 single-word instructions (12-bit opcode width), a Watchdog Timer with on-chip RC oscillator, Power-on Reset, Brown-out Reset, and a 4.5 ms power-on timer. The device runs from an internal RC oscillator up to 20 MHz or an external clock source, providing flexibility for timing-critical applications. The 12 I/O pins can source/sink up to 25 mA each, directly driving LEDs and small relays without buffer transistors. Architecturally, the PIC16F54 uses a Harvard RISC core with separate program and data buses, enabling most instructions to execute in a single cycle. The 12-bit instruction word yields a 2:1 code compression advantage over 8-bit instruction MCUs in its class, reducing Flash usage. The device has no interrupt controller (baseline PIC), so all event handling is polling-based, simplifying deterministic loop timing for hard real-time tasks. Typical applications include appliance controls (washing machines, microwave ovens, coffee makers), LED lighting controllers, battery chargers, small motor control, security keypads, toys, and automotive body electronics. The wide 2.0 V to 5.5 V supply range allows direct 3.3 V or 5 V operation from either alkaline or Li-ion battery stacks. The flash programmability enables in-field firmware updates and inventory-friendly blank-stock programming. When designing with this device, note that the baseline PIC16F5X core has NO interrupts - timing must be polled. For applications requiring interrupts, peripherals, or more memory, migrate to PIC16F1xxx or PIC16F1xx enhanced mid-range. The SSOP-20 footprint is a tighter surface-mount package than DIP-18, requiring reflow soldering.

PIC16F57-E/P

PIC16F57-E/P - 8-Bit 20MHz Flash MCU | Microchip Technology

The Microchip Technology PIC16F57-E/P is a FLASH-based 8-bit CMOS PICmicro microcontroller with 3KB program memory, 72 RAM bytes, 12 I/O ports, and a 20MHz clock in a 28-pin PDIP package. It executes instructions in as little as 200 nanoseconds and uses a compact instruction set containing only 33 single-word instructions. The device is suitable for automotive and industrial control applications and is identified as an active product in the verified specifications. A microcontroller is a programmable semiconductor that integrates a CPU, program memory, data memory, I/O, timers, and control peripherals into one device. The PIC16F57 belongs to the PIC16F family, which combines 8-bit processing with flash programmability and a compact instruction set. In the power-management and embedded-control hierarchy, it is a general-purpose microcontroller rather than a power IC or analog converter. Key features include 3KB of flash program memory organized as 2K by 12, 72 bytes of RAM, 12 I/O ports, a 20MHz maximum clock speed, and a 28-pin PDIP package. The extended-temperature ordering code is associated with operation across industrial and automotive environments. The small instruction set can simplify firmware development, while flash memory permits field reprogramming without a separate programmable ROM device. Architecturally, the PIC16F57 uses the PICmicro processor core with 200ns instruction execution and a RISC-oriented 33-instruction set. A 20MHz clock supports high-rate control and event processing, while the 12 available I/O pins allow digital interfaces to external sensors, relays, indicators, and logic. The manufacturer product page specifically identifies the family as adaptable to automotive and industrial systems. Typical applications include compact industrial controllers, automotive auxiliary-control modules, appliance-control boards, simple instrumentation, and embedded products requiring flash-reprogrammable logic. The PDIP package also provides through-hole assembly compatibility where insertion or rework tooling is preferred over fine-pitch surface mounting. The principal design consideration is supply and peripheral verification because the retrieved snippets do not expose a complete pinout, timer configuration, oscillator detail, or automotive qualification statement for this exact order code. Designers should preserve adequate input/output voltage headroom, apply decoupling at the supply pins, and validate timing against the selected oscillator and firmware configuration. This page combines manufacturer information, distributor data, package details, and application guidance to support component selection and sourcing decisions.

The Microchip Technology PIC16F57-E/SO is an 8-bit PICmicro RISC microcontroller with a 20 MHz maximum clock, 3 KB of Flash program memory, 72 bytes of RAM, and 20 general-purpose I/O lines in a 28-pin SOIC package. Its 200 ns instruction execution and 33 single-word instruction set provide a compact embedded-control platform for applications requiring deterministic control, modest program storage, and broad digital I/O. A microcontroller is a programmable semiconductor that integrates a CPU, nonvolatile program memory, data memory, and peripheral interfaces into one device. The PIC16F57 belongs to the PIC16 family and uses the PIC16 CPU architecture. Compared with larger 32-bit microcontrollers, its simpler instruction set and smaller memory organization can reduce firmware complexity in cost-sensitive control systems while preserving the peripheral integration needed for standalone operation. The verified headline specifications include 20 MHz maximum operating frequency, 3 KB of Flash memory organized as 2K × 12, 72 bytes of on-chip data RAM, and 20 I/O lines. Flash memory supports in-circuit reprogramming and is appropriate for firmware that must be updated during production or field maintenance. The 20 MHz clock supports faster control-loop execution and reduces execution time compared with lower-speed PIC16 devices, although the final system timing still depends on the selected oscillator and peripheral configuration. PIC16F57 devices use Microchip’s 8-bit PIC architecture with single-word instructions and a 200 ns instruction execution capability. The device provides general-purpose digital I/O for switches, relays, indicators, sensors, and discrete actuators. Because the verified source set does not expose the complete peripheral list, detailed timer, comparator, interrupt, and electrical limits should be checked in the manufacturer’s PIC16F57 documentation before final schematic or firmware sign-off. Typical uses include industrial control modules, appliance controllers, small motor-control boards, instrumentation interfaces, and embedded automation products. Its 20 I/O lines allow a board to connect multiple digital inputs and outputs without requiring an external I/O expander. The 3 KB Flash space is best suited to compact control logic rather than large protocol stacks, graphical interfaces, or data-intensive workloads. Designers should verify the exact operating-voltage limits, temperature grade, oscillator configuration, programming interface, and all peripheral pin assignments from the manufacturer datasheet. PCB layouts should route the programming and reset functions for reliable field programming, and firmware should include brownout, startup, and unused-pin handling appropriate to the selected configuration. This page combines verified distributor pricing, package information, temperature-grade alternatives, parameter comparisons, and practical selection guidance. It also distinguishes true same-package drop-in choices from related PIC16 devices that require different footprints, helping engineers avoid mechanically incompatible replacements.

PIC16F57-E/SP

PIC16F57-E/SP - 8-Bit 20MHz 3KB Flash MCU 28-SPDIP | Microchip

The Microchip PIC16F57-E/SP is a baseline 8-bit PICmicro RISC microcontroller built around a 200 ns instruction-execution engine with only 33 single-word instructions, delivering 3 KB (2 K x 12) of on-chip Flash program memory and 72 bytes of RAM in a 28-pin SPDIP through-hole package. The '-E' suffix denotes the extended temperature grade (-40 °C to +125 °C), qualified for harsh industrial and automotive under-hood environments where standard commercial parts would fail. Operating from 2.0 V to 5.5 V (the mid-range PIC16F5X supports 2.0 V operation while the data also lists 4.5 V-5.5 V typical application), the device is clocked at up to 20 MHz from an external resonator or internal RC, providing 20 I/O pins grouped into ports A/B/C for digital I/O, key-scan, and simple control tasks. The PIC16F57 belongs to the PIC10/16/18 family of 8-bit microcontrollers, the workhorse category of Microcontrollers > 8-bit MCUs > baseline PIC16 within the broader microcontroller taxonomy (MCU → 8-bit MCU → embedded controller → semiconductor). The family offers 12-bit-wide instructions, 2:1 code compression relative to legacy 8-bit CISC competitors, an 8-level hardware stack, a 2 K x 12 Flash program counter, and a watchdog timer with its own on-chip oscillator for safety-critical applications. Compared with newer PIC16F1xxx parts, the PIC16F57 omits peripherals such as ADC, PWM, EUSART, and interrupt controller to keep silicon cost minimal - it is intentionally targeted at glue logic replacement, encoder/decoder pairings, and low-cost state-machine duties. Key features include 3 KB (2048 words) of self-programmable Flash, 72 bytes of general-purpose RAM, 20 digital I/O lines with individual direction control, a programmable prescaler for the TMR0 8-bit timer, and a power-on reset / power-up timer / brown-out reset that holds the core in reset until VDD reaches a valid level. The 28-SPDIP package is the legacy through-hole format preferred for hobbyist, education, and breadboard-friendly designs, lending itself to manual rework and socketed prototyping. The /SP suffix matches Microchip's standard 28-pin 0.300 inch PDIP outline shared across PIC16 and PIC18 midrange families, easing PCB reuse between DIP-line projects. Typical applications include automotive relay and lamp drivers, appliance user-interface encoders, sensor-to-relay glue logic, low-cost remote-control transmitters, security keypads, LED chasers, and educational microcontroller labs. Designers also deploy it as a low-cost companion controller in larger systems where the main processor is starved of GPIO or where a deterministic 200 ns instruction cycle out-performs an interpreted state machine. For reliable operation, place a 100 nF decoupling capacitor as close as possible to the VDD pin and a 10-100 µF bulk reservoir at the board supply input; maintainer the MCLR pin tied to VDD through a 10 kΩ pull-up with a 100 nF cap for clean reset behaviour; oscillator traces should be kept short and guarded with a ground ring to keep external clock or crystal signals clean.

PIC16F57-I/P

PIC16F57-I/P - 8-Bit 20MHz 3KB Flash MCU | Microchip | DIP-28

The Microchip Technology PIC16F57-I/P is an 8-bit Flash-based RISC microcontroller delivering 20 MIPS (200 ns instruction cycle) with 3 KB (2K x 12) of Flash program memory, packaged in a 28-pin PDIP (DIP-28, 600 mil) through-hole format. The -I industrial temperature grade extends from -40C to +85C, and the part operates from a 2.0 V to 5.5 V supply across the PIC16F5x baseline family. An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, integrating a CPU core, program memory (Flash/ROM), data RAM, peripheral set (timers, ADC, communication interfaces), and I/O on one die. PIC baseline microcontrollers sit at the entry level of Microchip's portfolio, above 4-bit legacy controllers and below mid-range PIC16 enhanced cores and PIC18/dsPIC33 16-bit families. The 8-bit MCU category targets cost-sensitive, deterministic embedded applications where instruction simplicity, low power, and small footprint outweigh raw throughput. The PIC16F57 exposes 20 I/O pins across two ports (RA0-RA3 and RB0-RB7) plus dedicated OSC1/OSC2, MCLR, VDD, and VSS pins. Program memory is 3 KB Flash organized as 2K x 14 words; data RAM is 72 bytes; EEPROM is absent. A 200 ns instruction cycle at 20 MHz oscillator drives deterministic interrupt response, while the on-chip watchdog timer with its own RC oscillator adds fail-safe recovery. Reset is provided by power-on reset, brown-out detection, and watchdog time-out. Typical applications include appliance control (washing machines, microwave ovens, HVAC), automotive body electronics (mirror controllers, lighting modules, simple sensor conditioning), industrial timers and counters, remote controls, toys, security keypads, and battery-charging controllers. The wide 2.0 V to 5.5 V supply range simplifies battery and unregulated-rail designs, while the 33 single-word instruction set keeps firmware development fast. Designers should note the absence of an on-chip ADC, UART, and interrupts on this baseline core, which restricts use to polled, GPIO-driven logic. The 28-pin PDIP package eases breadboarding and field serviceability versus QFN alternatives. Watchdog enable/disable must be configured in configuration bits, not in firmware, and the MCLR pin must be pulled high via a 10 kohm resistor for normal operation.

The Microchip Technology PIC16F57-I/SO is an 8-bit PIC16-family Flash microcontroller delivering 3KB (2K x 12) of program memory, 72 bytes of RAM, and 20 digital I/O pins, all housed in a 28-pin SOIC (300 mil) package. It executes instructions at 20 MHz (200 ns instruction cycle) from a 4.5V to 5.5V single supply and offers 12-bit-wide instructions with 33 single-word instructions in its RISC-based instruction set. Background: An 8-bit microcontroller (MCU) is a single-chip computer integrating a CPU, non-volatile program memory (Flash/ROM), working RAM, and peripheral I/O on one die. The PIC16F5X family is one of the original baseline PIC architectures and belongs to the broader Microchip PIC16 -> 8-bit MCU -> microcontroller -> embedded controller -> semiconductor taxonomy. Its 12-bit-wide opcode is an early hallmark of cost-optimised baseline PICs and yields approximately 2:1 code density versus typical 8-bit CISC MCUs. Key features of this PIC16F57 include a 20 MHz internal clock domain (4 MHz instruction rate from a 4x PLL-less divider), 3KB self-programmable Flash, 72 bytes RAM, two 8-bit timer/counters (TMR0, TMR2-class) with one option for a watchdog timer, a programmable code protection scheme, and in-circuit serial programming (ICSP) via dedicated RB6/RB7 pins. The 28-SOIC package offers a 7.50 mm body width (300 mil) for hand-solderable prototype-friendly layouts and is rated -40C to +85C in the industrial -I temperature grade. Typical applications include low-cost appliance controllers, automotive body and aftermarket modules (pre-CAN era), industrial timers and counters, sensor pre-filters, and small white-goods user-interface boards. The wide 4.5-5.5V supply range tolerates legacy 5V system rails common in industrial PLCs and HVAC controls. When designing with the PIC16F57, keep in mind that the baseline PIC16F5X instruction set is NOT binary-compatible with mid-range PIC16F1xxx devices and uses a separate toolchain (MPLAB XC8 supports it via the -mcpu=pic16f5x option). Always reserve RB6 and RB7 for ICSP to enable in-field firmware updates without removing the chip.

PIC16F57-I/SP - 20MHz 8-Bit Flash MCU | Microchip

The Microchip Technology PIC16F57-I/SP is a 20 MHz, 8-bit FLASH-based PIC microcontroller with 3 KB (2K x 12) of program memory, 72 bytes of RAM, and a 28-pin SPDIP package. It uses the PIC16 RISC architecture, supports 12 I/O ports according to the distributor listing, and executes 200 ns instruction cycles through its 33-instruction set. The device is positioned for entry-level embedded control across automotive, industrial, appliance, and consumer applications. A PIC microcontroller is an embedded processor that combines a compact CPU core, program memory, data memory, and peripherals in one integrated circuit. PIC16 devices form the entry level of the PICmicro family, using a RISC-oriented instruction set and a compact architecture suited to control logic, timers, digital I/O, and small state machines. Microchip describes the PIC16F57 as a FLASH-based member of this family, allowing firmware updates without removing the device from its target circuit. The supplied data identifies a maximum clock frequency of 20 MHz, a 200 ns instruction execution time, and a 33-single-word instruction set. Its 3 KB FLASH program memory is specified as 2K x 12, while Mouser lists 72 bytes of RAM and 20 I/O-related information. These attributes make the PIC16F57-I/SP suitable for compact embedded controllers where program memory, pin count, and simple firmware execution are more important than high peripheral integration or large data storage. The part is identified by the I/SP ordering suffix in distributor results, with the verified listing specifying a 28-SPDIP package. The target’s supply and exact electrical limits are not consistently available in the supplied snippets, so any absent technical parameter is marked for verification rather than inferred. A lifecycle result identifies the family as active, but production status and stock should be confirmed with the manufacturer or an authorized distributor before procurement. Typical use cases include small appliance controllers, industrial automation modules, automotive accessory logic, consumer products, and general-purpose embedded control boards. The 20 MHz operating speed and 8-bit architecture suit periodic sampling, relay or indicator control, key scanning, and simple communication or timing routines. The 28-pin SPDIP package is particularly convenient for prototyping, automated assembly, and educational or legacy designs that already use through-hole footprints. For PCB design, verify the exact pin assignments from the manufacturer datasheet before assigning signals or power. The MCU requires correct oscillator, reset, programming, decoupling, and I/O routing even though the supplied search results do not provide a complete pin table or application circuit. Firmware should use the PIC16F57 memory and peripheral definitions appropriate to the exact device variant, and production designs should account for the available 3 KB program memory and 72 bytes of RAM. This page consolidates the verified manufacturer and distributor descriptions, package information, identified alternatives, and practical selection context for engineers comparing PIC16F57 variants. It is intended to make the 20 MHz 8-bit MCU decision faster while preserving uncertainty where the supplied sources do not establish a complete electrical specification.

PIC16F57-I/SS - 8-Bit 20MHz Flash MCU | Microchip Technology

The Microchip Technology PIC16F57-I/SS is an 8-bit PIC RISC flash microcontroller with 3KB of program memory, 72 bytes of RAM, 20 I/O pins, and a maximum clock frequency of 20MHz, housed in a 28-pin SSOP package. The -I suffix denotes the industrial temperature range of -40°C to +85°C, while /SS identifies the SSOP package configuration. A microcontroller is a programmable control IC that integrates a processor core, memory, I/O ports, and peripherals into one device. The PIC16F57 belongs to the PIC16 family, a hierarchy of 8-bit RISC microcontrollers within the broader embedded-control and semiconductor categories. Its architecture executes 33 single-word instructions with a stated 200ns instruction-execution time, making it suitable for compact embedded control systems. The device provides 3KB, organized as 2K x 12, of flash program memory and 72 bytes of RAM. Its 20 I/O pins support digital control and communication tasks, while its 20MHz operating capability gives designers additional timing headroom for motor, display, sensing, and communications-oriented embedded products. The manufacturer positions the PIC16F57 for adaptation to automotive, industrial, and similar embedded applications. PIC16F57 devices use the PIC RISC architecture with a compact instruction set rather than a complex multi-cycle processor architecture. Flash-based program memory supports field-programmable firmware workflows, while the small RAM footprint favors compact control tasks that do not require extensive buffering. Firmware and hardware design should still be checked against the complete Microchip datasheet for peripheral availability, electrical limits, programming requirements, and package dimensions. Typical uses include simple industrial controllers, automotive accessory-control modules, sensor interfaces, LED and display controllers, communications equipment, and compact embedded products. Its 20 I/O pins and 20MHz clock are the principal capacity constraints: designs requiring more memory, more pins, a richer peripheral set, or a larger RAM buffer should compare other PIC16-family devices before finalizing the design. The primary engineering consideration is package continuity. The /SS device uses a 28-pin SSOP footprint, so a substitute must match both the lead arrangement and device function. Commercial alternatives with different package suffixes, such as /SO, /P, or /SP, require different PCB land patterns and are therefore not direct drop-in replacements for an existing /SS assembly. This page consolidates verified manufacturer and distributor information, package-focused replacement guidance, pricing, and application-oriented engineering notes. It distinguishes true same-package options from merely related PIC16F57 order codes, helping engineers make procurement and PCB-reuse decisions without confusing similar family members with drop-in equivalents.

The integrated analog blocks allow direct interface with sensors (e.g., thermistors, photodiodes) without external op-amps, while the dual comparators support window detection and zero-crossing circuits. The internal 8 MHz oscillator reduces external component count, though an external crystal can be added for timing-critical applications. Typical applications include sensor signal conditioning, battery chargers, LED drivers, consumer appliances, and industrial control modules where integrated analog reduces board area. The PIC16F570-E variant supports the extended temperature range, making it suitable for industrial and outdoor environments. Designers benefit from Microchip's MPLAB X IDE and free development tools, including XC8 compiler and PICkit programmer support. When designing with this MCU, allocate careful pin planning because the dual op-amp and comparator pins are multiplexed with digital I/O; ensure the analog functions you need are available on the desired pins. Decouple VDD with a 100 nF ceramic capacitor close to the package and follow Microchip's SPDIP PCB layout guidelines to minimize noise coupling into the analog blocks.

It combines a 20 MHz CPU core with 3 KB (2K x 12 words) of Flash program memory, 132 bytes of data RAM, and a unique on-chip analog subsystem that includes a multi-channel ADC, two operational amplifiers, and two comparators. The industrial temperature grade (-40C to +85C) and 28-UQFN package make it a compact analog-front-end MCU for cost-sensitive embedded designs. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, data memory, and peripheral interfaces into one IC. The PIC16F570 belongs to the PIC16 mid-range family - 8-bit RISC microcontrollers known for deterministic instruction execution (200 ns per instruction at 20 MHz), Harvard architecture with separate program and data buses, and a broad ecosystem of MPLAB X development tools. PIC16 MCUs sit below PIC18/PIC24 in Microchip's 8-bit portfolio, offering lower cost and smaller footprints than PIC24/dsPIC parts while providing more on-chip analog than baseline PIC10/12/16F5xx devices.

The 28-UQFN package provides a small 4x4 mm footprint suitable for space-constrained PCB designs while exposing 23 I/O pins. The device supports In-Circuit Serial Programming (ICSP) and In-Circuit Debugging (ICD) via standard 2-wire interfaces. Architecturally, the PIC16F570 uses a Harvard RISC core with a 14-bit instruction word, 8-bit data path, and a 2-stage pipeline, delivering 200 ns instruction time at 20 MHz. The on-chip op-amps and comparators are routed through dedicated analog I/O pins and can be configured during runtime to condition sensor signals before ADC sampling - effectively replacing discrete analog front-end ICs in many designs and lowering BOM count. The 10-bit ADC with selectable reference and acquisition time delivers approximately 1 LSB accuracy at moderate conversion rates. Typical applications include battery chargers and power management controllers, LED lighting controllers, sensor signal conditioning modules, smoke detectors, white-goods user-interface boards, and small motor control loops. The integrated op-amp + comparator + ADC chain is particularly useful for closed-loop current/voltage sensing without external analog ICs. Designers select the PIC16F570 when they need more analog integration than PIC16F505/506 but smaller code and lower cost than PIC16F193x parts. When designing with this part, ensure that the ICSP/ICD pins (RB6/RB7) are not loaded with low-impedance circuits during programming. Use MPLAB X IDE with XC8 compiler for firmware development, and select a VDD decoupling network of 100 nF plus 10 uF bulk capacitance near the UQFN exposed pad. The exposed thermal pad must be soldered to the ground plane for mechanical reliability and electrical performance.

It combines a 12-bit program word with integrated analog functions, including an ADC, dual op amps, and two comparators. The -40°C to +85°C industrial temperature grade and 2 V minimum operating supply make the PIC16F570-I/SS suitable for cost-sensitive embedded control systems running from 2 V to 5.5 V. The PIC16F570-I/SS combines integrated Analog with the intelligence of a PIC microcontroller to create a low cost MCU suitable for a wide range of applications. Its on-board analog resources reduce the need for separate ADC, comparator, and signal-conditioning components. The MCU also supports 24 I/O, according to the product listing, allowing compact designs to connect discrete sensors, indicators, actuators, and communication interfaces while conserving board area. Key device characteristics include 3 KB of Flash memory organized as 2K x 12, 64 bytes of RAM, a 200 ns instruction execution capability, and a compact instruction set of 33 single-word instructions. The industrial-temperature suffix identifies operation across the -40°C to +85°C range, while the SSOP suffix identifies the 28-lead surface-mount package used by the -I/SS orderable part. Flash programming allows in-circuit firmware updates and simplifies product revision control. The device uses the baseline PIC16 8-bit RISC architecture, combining a compact instruction set with a straightforward register file and integrated peripherals. This architecture is useful for cost-sensitive controllers that execute control loops, monitor analog signals, and manage discrete outputs. Because the 3 KB Flash and 64 bytes of RAM are modest, firmware design should prioritize compact tables, interrupt-efficient polling, and avoidance of unnecessary library overhead. Typical applications include industrial sensor and monitor modules, compact temperature or process transmitters, motor and actuator controllers, lighting-control boards, consumer appliances, and low-cost battery-operated instruments. The integrated ADC, dual op amps, and two comparators are particularly useful in designs where analog front-end conditioning, threshold detection, and MCU control are combined in one package. When laying out the PCB, place the decoupling capacitor close to VDD and AVSS connections and route analog inputs away from switching nodes. Use the manufacturer pin-description table in the PIC16F570 data sheet before assigning PCB tracks, especially for analog, comparator, and programming pins.

The Microchip Technology PIC16F570T-I/MV is an 8-bit flash microcontroller that combines an integrated analog engine with the intelligence of a PIC16 core, offered in a compact 28-pin UQFN (MV) surface-mount package with tape-and-reel packaging. It integrates 3 KB of flash program memory, 64 bytes of RAM, and a peripheral mix that includes an 8-channel 8-bit ADC, two operational amplifiers, two comparators, and a configurable reference, all rated for operation from 2.0 V to 5.5 V across an industrial -40 C to +85 C temperature range. An 8-bit microcontroller (MCU) is a compact programmable processor that combines a CPU, on-chip memory, and a fixed set of peripherals (ADC, timers, communications, analog) into a single device. Within the broader semiconductor taxonomy, MCUs sit under microcontrollers, then embedded processors, then logic/semiconductor devices. Microchip's PIC16 family targets cost-sensitive applications that need reliable 8-bit performance with deterministic interrupt response, and the PIC16F570 distinguishes itself by integrating true analog building blocks (op-amps and comparators) directly on-die. Key features include 3 KB self-programmable flash (up to 100,000 erase/write cycles), 128 bytes of EEPROM, and a 25 I/O pin budget with high-current sink/source capability. The dual on-chip op-amps can be configured as buffers, amplifiers, or filters, while the two comparators share an internal 0.6 V/1.2 V/2.5 V reference. Eight MHz internal oscillator eliminates external crystals in cost-sensitive designs, and in-circuit serial programming (ICSP) allows in-field firmware updates. Typical applications include industrial sensor conditioning loops, battery chargers, motor control front-ends, smart thermostats, low-end consumer appliances, and LED lighting controllers. The combination of integrated op-amps and comparators makes the PIC16F570T-I/MV particularly well-suited to closed-loop analog systems where PCB area and BOM cost matter more than raw CPU throughput. When designing with this device, keep analog and digital grounds separated and meet at a single point near the IC to avoid noise coupling into the op-amp/comparator stages. Use the internal 8 MHz oscillator only when timing tolerance is non-critical, since factory trim accuracy is approximately +/- 1 percent at room temperature.

PIC16F570T-I/SS - 8-Bit MCU, 3KB Flash, 28-SSOP | Microchip

The Microchip Technology PIC16F570T-I/SS is an 8-bit PIC16 RISC flash microcontroller with integrated analog peripherals, running at up to 20 MHz instruction clock and housed in a 28-pin SSOP package. Key headline parameters are 3 KB (2K x 12) of FLASH program memory, 132 bytes of data RAM, and an integrated 8 MHz internal oscillator, all in a 5.30 mm SSOP-28 (SS) outline supplied on Tape & Reel (the "T" suffix). A PIC (Peripheral Interface Controller) microcontroller is a compact RISC-based computing core with on-chip program memory, data RAM, and integrated peripherals such as timers, ADC, comparators, and communication blocks. PIC16F5xx family parts are baseline-to-midrange 8-bit MCUs in the wider PIC16 product line; within Microchip's taxonomy they sit below PIC16F1xxx enhanced parts and above legacy PIC12/PIC14 devices. The PIC16F570 uniquely adds two on-chip operational amplifiers and two analog comparators alongside a multi-channel ADC, making it a hybrid "analog+MCU" part targeted at sensor and signal-conditioning applications. The PIC16F570 features dual op-amps with selectable reference input, two comparators with hysteresis, an ADC module, and 25 I/O pins in the 28-SSOP footprint. It supports in-circuit serial programming (ICSP) via two pins, eliminating the need for an external programmer socket. The device operates across 2.0 V to 5.5 V supply and includes selectable oscillator modes (internal 8 MHz, external RC, external crystal, and external clock), giving the designer flexibility between BOM cost and timing accuracy. Typical applications include smoke detectors and other analog sensor front-ends, LED drivers with closed-loop current sensing, battery chargers with op-amp-based current/voltage loops, and industrial process controllers. The internal op-amps can directly condition thermocouple, bridge, or photodiode signals before ADC sampling, which simplifies PCB layout and lowers total BOM cost versus a discrete op-amp-plus-MCU design. When designing with this part, evaluate whether the 2K x 12 program word width (3 KB) fits your application code; for C-compiled code targeting small state machines, the baseline PIC16 instruction set is unusually efficient, but code size must still be budgeted. Note the SSOP-28 package is pin-limited for designs needing many I/Os. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet. Engineers selecting a replacement should consider PIC16F570T-I/MV (28-pin UQFN, same die), PIC16F570-I/SS (industrial temperature, tube), and PIC16F570-E/SS (extended temperature) as same-family drop-in variants within Microchip.

PIC16F57T-E/SO - 8-Bit 20MHz PIC16 MCU, 3KB Flash | Microchip

The Microchip Technology PIC16F57T-E/SO is a flash-based, 8-bit CMOS microcontroller from the PIC16F5X family, executing instructions in 200 ns and packaged in a 28-pin SOIC wide-body (SO) tape-and-reel format. It integrates 3KB (2K x 12) of flash program memory, 72 bytes of RAM, 20 MHz maximum oscillator input, and 20 I/O pins on a 0.5 mA typical operating supply. The -E suffix denotes the extended industrial temperature grade of -40C to +125C, with the device operating from 2.5 V, 3.3 V, or 5 V supplies. What is a PIC16F5X microcontroller? The PIC16F5X is a baseline 8-bit RISC microcontroller family from Microchip, designed as a simple, low-cost entry point into the PIC architecture. PIC microcontrollers sit within the broader category of microcontrollers, which are single-chip computers integrating CPU, RAM, non-volatile program memory, and I/O peripherals. Within the MCU taxonomy, the PIC16F5X belongs to the 8-bit MCU tier using a RISC (Reduced Instruction Set Computing) architecture, distinct from 16-bit PIC24, 32-bit PIC32, and Cortex-M families. The PIC16F5X uses a 12-bit instruction word and exposes 33 single-word instructions, delivering 2:1 code compression over competitive 8-bit MCUs in its class. The device features 33 single-word instructions, a two-level hardware stack, 8-bit timer/counter with prescaler, watchdog timer with its own on-chip RC oscillator, power-on reset, and power-saving SLEEP mode. It uses a Harvard architecture with separate program and data buses, achieving deterministic execution and most instructions completing in one instruction cycle. The 20 MHz input clock yields a 200 ns instruction cycle, and the on-chip RC oscillator eliminates an external resonator in many designs. Typical applications include automotive subsystems, industrial control logic, appliance control boards, sensor signal conditioning, low-end consumer electronics, LED driving, simple motor control, and battery-powered embedded devices where the -40C to +125C temperature range and tape-and-reel packaging make it suitable for high-volume surface-mount assembly. The SOIC-28 wide-body package is compatible with hand-soldering and automated SMT lines. When designing with this part, choose the -E (extended) grade for automotive or industrial temperature exposure and the standard -I grade for commercial/consumer designs. The flash memory is one-time programmable by Microchip; in-circuit serial programming (ICSP) is supported via dedicated RB6/RB7 pins, enabling firmware updates in production.

PIC16F57T-E/SS - 8-bit 20MHz 3KB Flash MCU 28-SSOP | Microchip

The Microchip Technology PIC16F57T-E/SS is an 8-bit PIC RISC microcontroller with 3KB (2K x 12) of Flash program memory, 72 bytes of RAM, and 20 digital I/O pins, housed in a 28-pin SSOP package with -40C to +125C extended-temperature grade. It executes instructions in 200 ns at a 20 MHz clock, supports a 4.5V to 5.5V supply, and ships in Tape & Reel packaging. What is an 8-bit Flash microcontroller? An 8-bit Flash microcontroller is a small, self-contained computer-on-a-chip that integrates a CPU, non-volatile Flash program memory, RAM, and peripherals on a single die. It belongs to the broader class of microcontrollers (MCU) under the larger semiconductor hierarchy: microcontroller -> embedded processor -> integrated circuit. The PIC16F57 sits within Microchip's baseline PIC16F family and is one of the original mid-range 14-bit instruction PIC16F5x devices, optimized for cost-sensitive applications requiring deterministic, low-pin-count control. Key features include 33 single-word instructions, a 12-bit wide instruction set that yields 2:1 code compression versus typical 8-bit CISC competitors, two 8-bit timer/counters, a watchdog timer with on-chip RC oscillator, and in-circuit serial programming (ICSP) via dedicated RB6/RB7 pins. The 20 MHz oscillator delivers 5 MIPS throughput. Architecturally, the PIC16F57T-E/SS uses a Harvard RISC core with separate program and data buses, allowing instruction fetch and operand access in a single cycle. The wide 12-bit opcode and 8-bit data path are tuned for compact assembly code on small ROM footprints, making it well suited to standalone control loops where a smaller, cheaper MCU replaces a discrete logic implementation. Typical applications include automotive body and chassis modules, industrial control logic, appliance controls, security and alarm panels, and general-purpose low-pin-count glue logic. The wide 4.5V to 5.5V supply tolerance and automotive AEC-Q100-style extended temperature range make it adaptable to harsh environments. When designing with this device, note that the PIC16F57 family is programmed via ICSP and does not expose all RAM and ROM addresses externally; code developed for the PIC16F57 cannot always be ported to enhanced mid-range PIC16F1xxx parts without recompilation. Provide adequate decoupling on VDD and a stable oscillator for reliable operation.
