PIC16F526T-I/MG - 1.5KB Flash 8-bit MCU, 20MHz QFN-16 | Microchip

The Microchip PIC16F526T-I/MG is an 8-bit Flash microcontroller built on a RISC architecture with 1.5KB (1K x 14) of program memory and 64 bytes of RAM, packaged in a compact 16-pin QFN (MG, 3x3 mm) with internal 8MHz oscillator support. It executes instructions at up to 20MHz (200ns instruction cycle) and is targeted at cost-sensitive embedded applications where board space is at a premium. What is a microcontroller (MCU)? An MCU is a single-chip computer that integrates a CPU core, program memory (Flash/ROM), data memory (RAM), and programmable peripherals into one package. PIC microcontrollers from Microchip Technology are 8-bit Harvard-architecture devices known for deterministic instruction timing, low power consumption, and a mature ecosystem of compilers, programmers, and debugging tools. Key features include 1.5KB self-programmable Flash program memory with 100K erase/write cycles, an 8-channel 8-bit analog-to-digital converter (ADC), an internal 8MHz precision oscillator, and ultra-low-power sleep modes drawing less than 100 nA. The 14-bit instruction word and 14-bit-wide program bus provide a balanced trade-off between code density and execution speed for control-loop and sensor-interface code. Typical applications include battery-powered sensor nodes, LED lighting controllers, consumer appliance user interfaces, low-cost motor control, and compact IoT edge devices. The wide 2.0V to 5.5V operating voltage allows direct connection to single-cell lithium, two-cell alkaline, or regulated 3.3V/5V rails. The internal oscillator eliminates external clock components, reducing BOM cost and PCB area. When designing with this device, note that the QFN-16 (MG) package has an exposed thermal pad that MUST be soldered to the PCB ground plane for thermal and electrical performance. In-system programming (ICSP) is supported via two dedicated pins (ICSPCLK/ICSPDAT), and the same pins are used for in-circuit debugging. Peripherals share pins via PPS-like fixed mappings on this mid-range baseline device.

The Microchip Technology PIC16F526T-I/ST is an 8-bit RISC PIC microcontroller with 1.5KB (1K x 12 words) of Flash program memory, 64 bytes of RAM, and 128 bytes of EEPROM data, housed in a 14-pin TSSOP package. It executes instructions at up to 20MHz from an internal oscillator, integrates an 8-channel 8-bit ADC, and supports supply voltages from 2.0V to 5.5V across the full -40C to +85C industrial temperature range. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, volatile data memory (RAM), and a set of programmable peripherals (ADC, timers, GPIO, communication blocks) on a single silicon die. Within the broader taxonomy, PIC16F526 belongs to the 8-bit PIC family, which sits under the RISC MCU class, which in turn is a sub-category of microcontrollers, embedded processors, and finally integrated circuits. Its small footprint and integrated analog make it well suited to cost-sensitive and space-constrained embedded designs where an external ADC and crystal would inflate both BOM and PCB area. Key features that distinguish this part include the nanoWatt Technology power-management suite (sleep current typically below 100 nA), a configurable internal oscillator that eliminates the need for an external crystal in most designs, an 8-bit ADC with 8 input channels, and 12 GPIO pins arranged for mixed digital/analog use. The Flash program memory supports in-circuit serial programming (ICSP), enabling firmware updates in the field without removing the device from the PCB. Architecturally, the PIC16F526 uses a Harvard-style 14-bit instruction set optimized for compact code density. The device includes a 4-channel comparator block and a capture/compare/PWM (CCP) module, both common peripherals in motor control and analog signal conditioning applications. Its internal oscillator is factory-calibrated to within +/-1 percent across voltage and temperature, allowing timing-sensitive UART and PWM designs to operate without external resonator components. Typical applications span small consumer appliances, sensor signal conditioning front-ends, low-cost LED lighting controllers, battery-powered remote controls, and white-goods user-interface modules. The wide operating voltage and integrated ADC simplify designs that previously required a dedicated analog front-end IC alongside the microcontroller. When designing with this part, evaluate whether the 1.5KB program memory and 64 bytes of RAM satisfy the firmware footprint. Applications requiring complex protocol stacks or graphical interfaces typically need a larger PIC16 or PIC18 device, but the PIC16F526 remains a strong choice where cost, small package size, and integrated analog are the dominant constraints. This page synthesizes distributor pricing, parametric data from the manufacturer datasheet, and drop-in alternative information specific to the 14-pin TSSOP footprint of the PIC16F526 family, providing an at-a-glance comparison that complements Microchip's product documentation.

The extended (-E) temperature grade spans -40 C to +125 C, suitable for industrial and automotive-grade applications. The PIC16F527 architecture uses a Harvard bus with separate program and data paths, which lets the CPU fetch the next instruction while reading the current operand. The 20 MHz oscillator produces a 200 ns instruction cycle; combined with single-cycle branching and single-cycle instruction execution for most opcodes, the device delivers approximately 5 MIPS throughput. On-chip peripherals are memory-mapped and configured through dedicated Special Function Registers, simplifying firmware development with Microchip's MPLAB X IDE and XC8 compiler. Typical applications include sensor signal conditioning with integrated op-amps, battery chargers using the ADC plus PWM for closed-loop current/voltage control, LED lighting drivers with smooth dimming via the CCP module, small appliances with capacitive-touch interfaces, and standalone motor-control loops using Timer1 plus comparator feedback. The wide operating voltage range of 2.0 V to 5.5 V and low Sleep current also make it suitable for remote controls and IoT edge nodes powered by coin-cell batteries. When designing with the PIC16F527-E/JP, place a 0.1 uF decoupling capacitor within 5 mm of the VDD pin and keep analog traces short and guarded to preserve ADC accuracy. The exposed thermal pad on the UQFN package must be soldered to the ground plane for mechanical strength and thermal dissipation. Unused op-amp and comparator inputs should be tied to known voltage levels through 10 kohm resistors to prevent parasitic current paths during Sleep transitions.

Typical uses include small environmental controllers, temperature-measurement products, analog alarm or threshold modules, compact appliance controls, sensor-conditioning boards, and low-cost industrial interface modules. A PIC16F527-I/SO-based design can combine digital control logic with analog sensing in one package, provided the selected operating mode, clock configuration, and peripheral assignments are supported by the specific pins used. For PCB implementation, treat the 20-SOIC footprint and every pin assignment as controlled by the manufacturer pin-description table.

The Microchip Technology PIC16F527T-I/JP is an 8-bit PIC16F-series Flash microcontroller running at 20MHz with 1.5KB (1K x 12) of program memory, housed in a 20-pin UQFN (3x3 mm) package with exposed pad. The 'T' suffix indicates tape-and-reel packaging and the 'I' indicates the industrial -40C to +85C temperature grade. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (Flash), data memory (RAM), and a configurable set of peripheral blocks such as timers, ADC, comparators, and communication interfaces. Within the broader taxonomy, the PIC16F527 belongs to the 8-bit microcontroller -> microcontroller IC -> embedded controller -> semiconductor family. Its integrated analog peripherals distinguish it from purely digital MCUs, making it a hybrid MCU-plus-Analog device. The PIC16F527 differentiates itself with integrated analog resources including an 8-bit ADC, two operational amplifiers, and two analog comparators. These on-chip analog blocks enable direct sensor conditioning and signal processing without external op-amps or analog front-end ICs. The 1.5KB Flash supports small in-application firmware upgrades, and the 64 bytes of data RAM provide working storage for sensor sampling loops. The 20MHz internal oscillator eliminates external crystal requirements in cost-sensitive designs. Architecturally the PIC16F527 uses Microchip's enhanced mid-range 8-bit core with a 14-bit instruction word and a 12-bit program counter resolution, which is why memory is specified as 1K x 12 rather than 1K x 8. The Harvard architecture separates program and data buses for deterministic instruction throughput. The wide operating voltage range (typically 2.0V to 5.5V) and low-power sleep modes suit battery-powered sensor nodes. Typical applications include consumer remote controls, IR transceivers, white-goods user-interface boards, low-cost motor control, battery chargers with analog feedback, and electronic toys. The integrated op-amps and comparators are particularly well matched to sensor signal-chain applications. When designing with the PIC16F527, ensure the exposed thermal pad on the UQFN-20 is soldered to a sufficiently large copper pour for both thermal dissipation and mechanical reliability. Decouple VDD with a 100nF ceramic capacitor placed as close to the pin as possible. Use the ICSP header for in-circuit programming rather than relying on socketed programming. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, giving engineers a single reference for PIC16F527T-I/JP selection and procurement.

It runs at up to 20MHz instruction clock, contains 1.5KB (1K x 12) of self-programmable flash program memory, and operates from 2.0V to 5.5V supporting 2.5V/3.3V/5V rails. What is a PIC16 microcontroller? A PIC16 microcontroller is a member of Microchip's mid-range 8-bit RISC MCU family built on a Harvard architecture. It belongs to the broader class of microcontrollers (MCU -> embedded controller -> semiconductor IC) and is widely used in cost-sensitive analog-intensive embedded designs where integrated op amps, comparators, and ADC reduce the external bill of materials. Key features of the PIC16F527T-I/ML include a 20MHz internal/external oscillator block, 1.5KB flash / 80 bytes RAM / 64 bytes EEPROM data, 14 I/O pins, an 8-channel 8-bit ADC, two operational amplifiers, two comparators with programmable reference, and an internal 4MHz RC oscillator. The device is also equipped with an enhanced low-power wake-up (WDT) and a hardware Universal Asynchronous Receiver-Transmitter (UART/SPI/I2C capable depending on peripheral map). The architecture uses a 14-bit instruction word with a single-cycle ALU, enabling deterministic throughput for closed-loop analog control. On-chip peripherals are accessed via a peripheral pin select (PPS) scheme in similar PIC16 parts, while the integrated dual op amps and comparators allow direct conditioning of analog signals such as sensor bridges or thermistor networks before ADC sampling. Typical applications include sensor signal conditioning, battery-powered IoT nodes, white-goods and appliance controls, lighting ballast control, smoke and gas detector front-ends, and small motor control loops. The integrated analog front end is particularly useful in optical modules, PIR motion detectors, and capacitive touch interfaces where PCB area is constrained. When designing with this device, allocate the exposed pad of the QFN package to a continuous ground plane for thermal dissipation and electrical performance; failure to solder the EP will degrade thermal behavior and may violate reliability budgets at high CPU loads. Brown-out and watchdog timer configuration must be set in CONFIG words at programming time.

The Microchip Technology PIC16F54-E/SO is a cost-optimized 8-bit flash-based CMOS microcontroller delivering 200 ns instruction execution in an 18-pin SOIC package. Headline parameters include 0.75 KB (768 bytes) of flash program memory, 25 bytes of RAM, 12 digital I/O pins, and a 20 MHz internal oscillator / 200 ns instruction cycle, making it one of the simplest PICmicro mid-range devices available today. The -E suffix denotes the extended operating temperature grade (-40C to +125C) and the /SO suffix identifies the 300-mil SOIC-18 surface-mount package with 1.27 mm terminal pitch. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (flash/ROM), data memory (RAM), and programmable I/O peripherals into one package. The PIC16F54 family belongs to the PIC16 mid-range architecture, a sub-class of microcontrollers -> CMOS microcontrollers -> embedded controllers -> semiconductor ICs. Its role in a system is to provide deterministic real-time control for low-cost applications where a 32-bit MCU would be overkill and discrete logic would be too bulky. Key features include 33 single-word instructions, a 12-bit wide instruction word (giving 2:1 code compression over typical 8-bit MCUs), an 8-bit timer/counter, a watchdog timer, and an internal 4 MHz RC oscillator with optional external crystal. Brown-out reset and power-on reset are built in, supporting supply voltages from 2.0 V (at 4 MHz) up to 5.5 V. Code protection prevents unauthorized firmware read-out. The PIC16F54 uses a RISC-style Harvard architecture with separate program and data buses, which is why its 200 ns instruction time remains consistent regardless of memory access. This deterministic behavior simplifies timing-critical control loops. Programming is supported through Microchip's ICSP (In-Circuit Serial Programming) interface, eliminating a separate programmer for prototype builds. Typical applications include automotive body controllers, industrial timer / counter modules, appliance control boards, simple sensor interfaces, low-end user-interface panels, and replacement of discrete logic in 18-pin form-factor designs.

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

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 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.

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.

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.

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 - 20MHz 8-Bit 768B Flash MCU SSOP-20 | Microchip
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 - 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.
