PIC16LF877A-I/L

PIC16LF877A-I/L - 8-Bit 10MHz MCU, 14KB Flash, 44-PLCC | Microchip

The Microchip Technology PIC16LF877A-I/L is an 8-bit RISC Flash-based microcontroller with 14KB (8K x 14) of program memory, packaged in a 44-pin PLCC (16.59x16.59 mm) form factor. It operates up to 10 MHz from a wide 2.5V/3.3V/5V supply and integrates 33 digital I/O, an 8-channel 10-bit ADC, two analog comparators, two capture/compare/PWM modules, and both SPI (3-wire) and I2C (2-wire) master/slave synchronous serial ports. The -I/L suffix denotes the industrial temperature range (-40C to +85C) and the lead-bearing PLCC carrier. An 8-bit PIC microcontroller is a Harvard-architecture RISC device that executes one instruction every clock cycle, with separate program and data buses that allow simultaneous instruction fetch and operand access. Within the broader taxonomy, the PIC16LF877A is part of the PIC16 mid-range family, which itself sits under Microchip's 8-bit PIC portfolio (PIC10/12/14/16/18), bridging simple 6/8-pin baseline parts and the higher-performance PIC18 series. The "LF" prefix indicates the extended low-voltage design, allowing operation down to 2.5V for battery and energy-efficient designs, while the "A" suffix denotes the enhanced Flash core with the self-programmable, ICD-capable silicon revision. Key differentiating features include 368 bytes of RAM, 256 bytes of EEPROM data memory, In-Circuit Serial Programming (ICSP) and In-Circuit Debugger (ICD) support, two 8-bit timers plus one 16-bit timer with 3 CCP modules in earlier silicon revisions, 8 channels of 10-bit A/D conversion, a parallel slave port, and a programmable brown-out reset. The PIC instruction set is only 35 single-word instructions, and the core is upwardly source-compatible with the PIC12CXXX, PIC16C5X, and PIC16C7X device families, simplifying migration. Architecturally, the PIC16LF877A combines a RISC engine with 14-bit wide instructions, a deep 8-level hardware stack, and on-chip Flash permitting self-programming in field. The integrated peripherals are addressable via banked SFRs and support DMA-style auto-increment addressing for ADC bursts, while the USART provides hardware-driven asynchronous framing for RS-232/RS-485 links without CPU overhead. The 44-PLCC variant is socketable, simplifying field service and rework versus QFP or QFN equivalents. Typical applications include industrial automation controllers, sensor and instrumentation front-ends, HVAC control boards, automotive body and interior ECUs, embedded data-acquisition front ends, and consumer appliance control panels. Its combination of analog integration and broad peripheral mix makes it a strong fit for any sensor-rich, battery-tolerant node requiring moderate compute. When designing with this part, plan for a single 2.5V to 5.5V rail and ensure your programmer supports ICSP on the working PCB, since field firmware updates typically use this pathway. Decoupling should include a 100 nF ceramic at VDD and a bulk tantalum or aluminum on AVDD, and unused analog inputs must be tied to VSS to minimize ADC shoot-through current.

Operating at up to 10MHz clock speed with a wide 2V to 5.5V supply range, this LF variant is optimized for low-power and low-voltage applications while maintaining the same peripheral set as the standard PIC16F877A. What is a microcontroller? A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (Flash/ROM), volatile working memory (RAM), and a range of peripheral interfaces (ADC, UART, timers, I/O) into one package. MCUs are the foundation of embedded systems and belong to the broader category of microprocessors and integrated circuits. The PIC16F family specifically uses Microchip's enhanced Harvard RISC architecture with a 14-bit instruction word optimized for deterministic real-time control.

The 44-QFN package provides a compact footprint with an exposed thermal pad for improved heat dissipation. The PIC16LF877A uses Microchip's nanoWatt Technology for extended battery life, with multiple low-power sleep/idle modes, programmable oscillator options including internal 31kHz to 8MHz RC oscillator, and software-controlled peripheral shutdown. The Harvard architecture with separate program and data buses allows simultaneous instruction fetch and data access, and the 8-level hardware stack plus 35 single-word instructions simplify firmware development in assembly or C (MPLAB XC8). Typical applications include industrial sensor monitoring, HVAC control, motor control feedback loops, low-power IoT edge nodes, automotive body electronics (with appropriate derating), consumer appliance control boards, and battery-powered instrumentation. The PIC16F877A's rich peripheral mix makes it especially suitable as a measurement and control front-end where deterministic timing and long product lifecycles are required. When designing with this device, ensure your toolchain is configured for the LF (low-voltage) variant: MPLAB X IDE with XC8 compiler is the standard development flow, and programmers like PICkit 3/4 or ICD debug the device via the ICSP interface. Designers migrating from PIC16F877A to PIC16LF877A should confirm supply voltage stays within 2.0-5.5V and verify ADC reference voltage scaling at low VDD.

PIC16LF877A-I/PT

PIC16LF877A-I/PT - 8-Bit 10MHz MCU, 14KB Flash, 44-TQFP | Microchip

The Microchip Technology PIC16LF877A-I/PT is a low-power 8-bit CMOS Flash microcontroller built on Microchip's PIC16 enhanced mid-range core, packaged in a 44-pin TQFP (PT) and offered as the LF variant with an extended 2.0V-5.5V operating range. The device integrates 14KB of Flash program memory (8K x 14 words), 368 bytes of SRAM and 256 bytes of EEPROM data memory, and executes instructions at up to 10MHz / 200ns per instruction cycle. Industrial-temperature ("I") screening covers -40C to +85C. An 8-bit microcontroller (MCU) is a single-chip computer that combines a CPU, program memory, data memory, and a curated set of peripherals on one die; in the broader taxonomy it sits under microcontroller -> embedded processor -> semiconductor. The PIC16F family pioneered Harvard-architecture 8-bit MCUs with RISC-like single-word instructions and was the workhorse platform for thousands of hobbyist, industrial, and educational designs. Key features of the PIC16LF877A-I/PT include 33 digital I/O pins, three timers (Timer0 8-bit, Timer1 16-bit, Timer2 8-bit), two Capture/Compare/PWM modules, an 8-channel 10-bit Analog-to-Digital Converter, two analog comparators, a synchronous serial port configurable as SPI or I2C, a USART with addressable RS-485 mode, a parallel slave port, and brown-out reset plus power-on reset. Architecturally the device pairs a 14-bit instruction word Flash with a 35-instruction core, an 8-bit data path, and a high-current sink/source capability on port pins (25mA per pin typical) that lets it drive LEDs and small relays directly. The LF process node trades absolute speed for lower VDD operation, retaining full peripheral compatibility with the F-version. Typical applications include industrial sensor interfaces, low-power data loggers, hobbyist robotics, automotive body controllers and aftermarket gauges, educational development platforms, and legacy embedded systems that need to retain a PIC16 footprint while modernising firmware. The 44-TQFP footprint also remains pin-compatible with several successors in the PIC18 family. When designing with the LF variant, remember that the 10MHz rating is at 5V; at 3.3V the maximum is typically 4MHz and the oscillator modes must be reconfigured. Always place decoupling capacitors (100nF ceramic) close to VDD/VSS pairs and route MCLR through a 10k pull-up unless in-circuit debugging is enabled.

PIC16LF877AT-I/PT

PIC16LF877AT-I/PT - 8-bit MCU, 14KB Flash, 33 I/O, 44-TQFP | Microchip

The Microchip PIC16LF877AT-I/PT is an 8-bit RISC microcontroller built on the PIC16 enhanced architecture, offering 14KB of in-circuit serial Flash program memory, 368 bytes of RAM, and 256 bytes of EEPROM in a 44-pin TQFP (10x10 mm) package. The "LF" prefix designates the wide-voltage, low-power (2.0V-5.5V) variant optimized for battery-friendly applications, while the "A" revision adds support for nanoWatt technology and improved peripherals versus the original PIC16F877. The "T" suffix indicates the part ships in tape-and-reel packaging, and "-I/PT" denotes the industrial temperature grade (-40C to +85C) in TQFP. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (Flash/ROM), data memory (RAM), and peripherals (timers, ADC, communication ports) into one IC. PIC microcontrollers sit in the 8-bit MCU hierarchy: microcontroller -> embedded controller -> semiconductor IC, and serve as the "decision makers" in embedded products from coffee makers to industrial drives. The 16F family is Microchip's mid-range 8-bit line with a 14-bit instruction word and 35 single-word instructions, enabling extremely compact code and deterministic interrupt response. Key features of the PIC16LF877AT-I/PT include: a 20 MHz maximum operating frequency (200 ns instruction cycle), a 10-bit ADC with up to 8 channels, two analog comparators, a Capture/Compare/PWM (CCP) module, enhanced Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART), Master Synchronous Serial Port (MSSP) supporting SPI and I2C, two 8-bit timers plus one 16-bit timer, a watchdog timer, in-circuit serial programming (ICSP), and nanoWatt power management with multiple sleep modes. The 20 MHz core paired with a 14-bit instruction word delivers approximately 5 MIPS of throughput, while the wide 2.0V-5.5V supply range allows direct operation from a single Li-Ion cell, two AA cells, or a regulated 3.3V/5V rail. Internal oscillators and PLL trimming on the LF variant further reduce external component count, simplifying layout for space-constrained designs. Typical applications include industrial sensor interfaces, motor-control front ends, low-power data acquisition nodes, automotive body electronics (non-safety), and consumer appliance controllers. The 44-pin TQFP exposes up to 33 digital I/O, sufficient for keypad scanning, LCD driving, and parallel bus bridging. Designers value this device for migration paths from older PIC16F877 designs that need lower voltage operation or a tape-and-reel SMD footprint. When designing with this part, allocate the oscillator and ICSP pins (OSC1/CLK, OSC2/CLKOUT, RB6/PGC, RB7/PGD) on dedicated PCB traces and add a 100 nF decoupling capacitor within 5 mm of VDD. Avoid mapping analog inputs to pins used by the comparator outputs without verifying alternate-function routing, and respect VDD/VSS pairing for the 44-pin TQFP power pins.

The 'LF' suffix indicates a wide 2.0 V–5.5 V operating range designed for battery-powered systems, while the 'T' denotes tape-and-reel packaging for high-volume assembly. A microcontroller (MCU) is a single-chip computer containing a CPU, non-volatile program memory (Flash), volatile working memory (RAM), and configurable peripheral blocks. The PIC16 family sits in Microchip's mid-range 8-bit portfolio, sitting between baseline PIC10/PIC12 devices and high-pin-count PIC18 parts, and is widely used in commercial and industrial embedded designs where deterministic instruction execution (200 ns per instruction at 20 MHz, 400 ns at 10 MHz) and a small footprint are critical. PIC MCUs ship in a hierarchical ecosystem (PIC10/PIC12/PIC16/PIC18) with NanoWatt variants that extend sleep-mode current well below 1 µA. Key features include a 14-bit instruction word, 35 single-word instructions, an internal 31 kHz–8 MHz oscillator with PLL options, two analog comparators, a watchdog timer, in-circuit serial programming (ICSP), and code protection.

The PIC16LF87T-I/SS is intended for low-power, peripheral-rich embedded applications where stable 8-bit performance matters more than raw MIPS. Its 2.0 V–5.5 V supply range, low sleep current, and integrated analog peripherals allow direct battery or USB-bus powered operation, and the 35-instruction RISC-like instruction set keeps firmware review, certification, and code-port tasks straightforward. Designers typically pair it with NanoWatt sleep modes, brown-out reset, and power-managed peripherals to extend battery life in field-deployed products. Typical applications include battery-powered sensor nodes, simple HMI panels with keypads and LCDs, low-speed USB/serial bridges, industrial control front ends, and consumer appliances such as white goods timers or remote controls. The wide operating voltage and integrated peripherals also suit handheld measurement instruments, security peripherals, and educational embedded platforms. Design consideration: when laying out the SSOP-20 footprint, keep the ICSP/ICD clock and data traces short and shield them from analog ADC inputs to prevent programming glitches during in-circuit debug, and place a 100 nF decoupling capacitor within 5 mm of VDD with a bulk 10 µF near the supply pin.

The LF prefix denotes the extended low-voltage operating range from 2.0 V to 5.5 V, making the part suitable for battery-powered and energy-harvesting designs. An 8-bit microcontroller (MCU) is a small, self-contained computer-on-a-chip that integrates a CPU, non-volatile program memory, working RAM, peripheral set and I/O pins into a single package. PIC microcontrollers specifically use a Harvard RISC architecture with separate program and data buses, which is why a 14-bit wide program word can coexist with an 8-bit data path. Within the broader power management hierarchy, this part sits inside the Microcontrollers category, which is a sub-family of Integrated Circuits used in embedded control. The LF88 family is optimized for low-power applications via Microchip's nanoWatt technology, with multiple power-managed modes that drop current consumption into the nanoamp range when peripherals are gated off.

The 28-QFN package with exposed pad supports extended industrial temperature operation from -40 C to +85 C (industrial grade marked by the I suffix). Internally the PIC16LF88 uses a 14-bit instruction word and an 8-level deep hardware stack. Its ADC can be clocked from a dedicated RC oscillator for noise-immune conversions, and the PWM module supports enhanced PWM modes with programmable dead-band control. The integrated synchronous serial port (MSSP) handles both I2C master/slave and SPI master/slave, while the AUSART provides RS-232 / RS-485 framing with a 9-bit address detect mode useful for multi-drop sensor networks. Typical applications include low-power sensor nodes, industrial control modules, battery-powered instrumentation, simple motor control and white-goods user interfaces. Its small QFN footprint and nanoWatt sleep modes also make it a common choice for handheld measurement devices. When designing with the PIC16LF88-I/ML, ensure that the exposed pad on the underside of the QFN is soldered to a sufficiently large copper pour for thermal dissipation and for the chip's ground reference. A 100 nF decoupling capacitor must be placed within 3 mm of the VDD pin, and the MCLR pin should be pulled high through a 10 kohm resistor unless an external reset supervisor is used.

What is a PIC16 microcontroller? The PIC16F family is a class of 8-bit RISC microcontrollers from Microchip Technology based on the Harvard architecture. PIC MCUs execute instructions in a single cycle (200 ns at 10 MHz) using a reduced instruction set of only 35 single-word instructions, which makes them deterministic, easy to program, and well suited for embedded control. PIC MCUs are categorized within the broader hierarchy: microcontroller -> 8-bit MCU -> RISC MCU -> embedded processor -> semiconductor. The PIC16LF88 sits in the enhanced mid-range sub-family with a 14-bit instruction word and 8-bit data path. Key features of the PIC16LF88 include nanoWatt Technology for power-managed sleep modes, a 10-channel 10-bit Analog-to-Digital Converter (ADC), two analog comparators, a USART module for serial communication, an MSSP module for SPI and I2C, a capture/compare/PWM (CCP) module, an enhanced CCP (ECCP) module, and 16 digital I/O pins with individual direction control. Internal oscillator options support operation without external crystals, and the device is in-circuit serial programmable (ICSP) for field firmware updates. The PIC16LF88 uses CMOS Flash technology with a 14-bit instruction word, 8-bit data bus, and a two-stage pipeline that overlaps fetch and execute to achieve single-cycle throughput for most instructions. The integrated nanoWatt power management provides multiple idle and sleep modes, a watchdog timer with on-chip RC oscillator, and a fail-safe clock monitor for industrial-grade reliability. The 256-byte data EEPROM allows non-volatile storage of calibration data, settings, and run-time parameters separate from the main Flash program memory. Typical applications include industrial sensor interfaces, low-power remote control units, battery-powered instrumentation, HVAC control nodes, small appliances with user interface, automotive body electronics subsystems (non-safety), home automation endpoints, and educational/hobbyist embedded platforms. The wide operating voltage and low-power nanoWatt modes also make it suitable for solar or energy-harvesting edge devices. Designers also use this MCU as an upgrade path from older PIC16C5X, PIC16C62xA, PIC16C7x, and PIC12CXXX designs because the PIC16LF88 maintains upward source-code compatibility. When designing with the PIC16LF88, ensure the Vdd decoupling capacitor (typically 0.1 uF ceramic) is placed within 5 mm of the Vdd pin, and that MCLR is pulled high through a 10 kohm resistor for normal operation. Program the configuration bits explicitly to select the desired oscillator source and watchdog behavior, because the ICSP programming tool cannot override configuration bit settings after they are written to the device.

PIC16LV54A-02/P - 2MHz 8-Bit OTP MCU | Microchip 18-DIP
PIC16LV54A-02/P

PIC16LV54A-02/P - 2MHz 8-Bit OTP MCU | Microchip 18-DIP

The Microchip PIC16LV54A-02/P is an EPROM/ROM-based 8-bit CMOS microcontroller belonging to the PIC® 16C5X family, featuring a 12-bit instruction word, an 8-bit data path, 768 bytes (512 x 12) of one-time-programmable (OTP) program memory, and a maximum clock speed of 2 MHz. Housed in an 18-pin DIP (0.300 inch, 7.62 mm) plastic through-hole package, this part supports a low-voltage operating range from 2.5 V to 5.5 V, making it the LV-variant for battery-friendly designs within the legacy PIC16C5X lineup. Twelve bidirectional I/O pins and a single 8-bit timer/counter (TMR0) address straightforward control tasks. What is an 8-bit OTP microcontroller? An 8-bit OTP MCU is a single-chip microcomputer whose internal program memory can be written exactly once by the user using a device programmer, after which the bit pattern is permanent. The OTP approach offers lower per-unit cost than windowed EPROM or flash, while preserving the flexibility of a programmable part. Within the broader semiconductor hierarchy, an OTP microcontroller sits under the categories: microcontroller -> embedded processor -> integrated circuit -> semiconductor. Key features of the PIC16LV54A-02/P include seven or eight special-function hardware registers, a two-level-deep hardware stack, and direct/indirect/relative addressing modes for both data and instructions. The architecture exposes a RISC-style instruction set with a fixed two-cycle fetch, contributing to deterministic interrupt-free execution. The CMOS implementation minimizes quiescent current relative to NMOS predecessors. Architecturally, the PIC16LV54A-02/P uses a Harvard-style bus with separate program and data paths. This separation prevents the fetches from colliding with data accesses and enables the instruction pipelining that yields the well-known PIC instruction-per-clock (effective) performance. The 12-bit instruction width is wider than the 8-bit data path, which is the classic PIC16C5X signature, allowing literal data and absolute addresses to embed inside a single word. Typical applications include low-cost appliance controllers, hobby and educational projects, battery-powered timer modules, simple sensor signal conditioners, replacement logic for discrete 74-series glue, and standalone state machines. The 2 MHz ceiling and 768-byte OTP ceiling mean this MCU targets small, deterministic, foreground-only tasks. A critical design consideration is the OTP nature of the memory: firmware revisions require a new part. Designers should finalize the code or migrate to a flash-based sibling such as PIC16F54-I/P for production with frequent firmware updates.

Key features include a fixed-length, single-cycle instruction set, 12 bidirectional I/O pins, an 8-bit real-time clock/counter with 8-bit prescaler, watchdog timer with on-chip RC oscillator, power-on reset, and brown-out protection. The "LV" prefix denotes low-voltage operation, allowing battery-powered designs to run directly from a single lithium cell (3.6 V max) without additional regulation. The PIC16LV54A-02/SO uses a Harvard-architecture RISC core that executes instructions in a single instruction cycle, providing deterministic timing for interrupt-driven and polled control loops. Its 33 instruction set enables compact code generation, while the OTP (one-time programmable) memory supports production programming with per-unit firmware customization. Typical applications include consumer appliance controls, battery-powered sensor interfaces, simple motor control, LED driver controllers, and replacement of discrete logic in legacy designs. The wide 2.0 V to 6.0 V range supports both 3.3 V and 5 V rails, simplifying integration into mixed-voltage systems.

An 8-bit microcontroller (MCU) is a small computer-on-a-chip integrating a CPU, RAM, non-volatile program memory (ROM/Flash/OTP), and peripheral I/O on a single die. Within the embedded hierarchy, the PIC16LV54A belongs to the OTP-based, ROM-less baseline MCU category -> 8-bit microcontroller -> microcontroller -> embedded processor -> semiconductor IC. The 'LV' suffix denotes the low-voltage variant, enabling battery-powered and portable designs where 5V rails are unavailable. Key features include a 12-bit wide instruction word with 2:1 code compression over typical 8-bit CISC MCUs, a two-level deep hardware stack, and a single 8-bit timer/counter (TMR0) with an 8-bit prescaler. Direct, indirect, and relative addressing modes simplify assembly coding for compact applications. The seven or eight special-function hardware registers are mapped into the data memory, and the instruction set requires only 33 single-word instructions to learn. Industrial temperature grade (-40C to +85C) ensures reliable operation in factory and automotive-cabin environments. Technically, the PIC16LV54A uses Microchip's classic Harvard architecture with separate program and data buses, allowing instruction fetch and data access in a single clock cycle. The 2 MHz oscillator input (the '-02' speed suffix) yields a 2 MHz instruction rate at 4:1 division in standard mode, sufficing for slow-loop control, keypad scanning, and LED multiplexing tasks. The 'A' revision brings enhanced electrical characteristics and the 'I' suffix denotes industrial temperature range. The OTP program memory allows one-time programming via a device programmer, making this part ideal for low-to-medium volume production where mask-ROM NRE is not justified. Typical applications include low-cost consumer appliances, remote controls, toy electronics, sensor signal conditioning, simple motor and relay drivers, LED lighting controllers, and battery-powered timers. The wide operating voltage makes it suitable for 2x AA / single Li-ion cell systems where 3.3V is the native supply. When designing with the PIC16LV54A-02I/P, note that OTP parts cannot be reprogrammed in-circuit; firmware must be fully validated on a windowed PIC16CR54A or flash-based PIC16F54 equivalent before committing to OTP.

It integrates 12 I/O pins, an 8-bit real-time clock/counter (TMR0), a two-level deep hardware stack, and a watchdog timer for reliable embedded control. The 'LV' designation indicates low-voltage operation supporting 2V to 3.8V supply, while the '02' suffix denotes 2 MHz maximum clock speed and the 'I' suffix specifies industrial temperature range (-40°C to +85°C). An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and peripherals on one silicon die. Within the broader taxonomy, the PIC16LV54A belongs to the 8-bit MCU class, which itself falls under microcontrollers, integrated circuits, and ultimately semiconductors. The PIC architecture uses a RISC-like instruction set with 12-bit wide opcodes and an 8-bit data path, achieving 2:1 code compression over typical 8-bit CISC competitors. Key features include 33 single-word instructions (industry-standard PIC instruction set), seven or eight special-function hardware registers, direct/indirect/relative addressing modes for both data and instructions, and low-power CMOS technology. The device consumes very low quiescent current in standby mode, making it suitable for battery-powered and energy-constrained applications. The 8-bit timer/counter TMR0 with a programmable prescaler supports timing, event counting, and simple PWM generation. Technically, the PIC16LV54A uses a Harvard architecture with separate program and data buses, enabling simultaneous instruction fetch and data access. The OTP (one-time programmable) memory supports field programming via standard Microchip development tools. Internal oscillator options and external clock input flexibility allow designers to trade off cost, accuracy, and power consumption. The two-level hardware stack limits call depth, which is typical for low-pin-count baseline PIC microcontrollers. Typical applications include battery-powered sensor interfaces, low-cost consumer electronics, appliance controllers, simple LED driving circuits, and industrial automation edge devices. Its 12 I/O pins, small footprint, and low-voltage operation also suit it for handheld instruments and wearable accessories where power efficiency and PCB area are critical. When designing with the PIC16LV54A-02I/SO, ensure VDD decoupling with 100 nF ceramic capacitors placed close to the supply pins. For OTP programming, leave the MCLR/VPP pin accessible on the PCB. Stack depth limitation requires careful coding - avoid nested subroutines beyond two levels. For new designs, consider the flash-based PIC16F54-I/SO as an alternative, which offers in-circuit reprogrammability in the same 18-SOIC footprint.

PIC16LV54A-02I/SS

PIC16LV54A-02I/SS - 8-bit 2MHz 768B OTP MCU | Microchip | SSOP-20

The Microchip Technology PIC16LV54A-02I/SS is an 8-bit RISC microcontroller from the PIC16C5x family operating at up to 2 MHz, housed in a 20-pin SSOP package and offering 768B (512 x 12) of one-time programmable (OTP) program memory. It is the low-voltage 'LV' variant of the PIC16C54A, supporting a 2.0V to 5.5V supply range with 12 I/O pins and 25 bytes of general-purpose RAM. The device targets cost-sensitive embedded control in industrial and automotive environments, with an industrial operating temperature range of -40C to +85C. What is an 8-bit OTP microcontroller? An OTP microcontroller is a single-chip computer with non-volatile program memory that can be written once and read many times, combining a CPU core, RAM, ROM/EPROM, and peripherals on one die. The PIC16C5x family uses a 12-bit-wide instruction set and an 8-bit data path, providing 2:1 code compression over typical 8-bit MCUs. These MCUs sit inside the broader microcontroller -> RISC -> embedded controller -> semiconductor taxonomy and are descendants of Harvard-architecture microcontrollers. Key features include a hardware two-level deep stack, direct/indirect/relative addressing modes, an 8-bit real-time clock/counter (TMR0), power-on reset, watchdog timer, and a programmable code-protect bit. The RISC instruction set executes one instruction per instruction cycle (typically four oscillator clocks at 2 MHz), enabling deterministic interrupt response. The device runs from a single supply rail and supports low-power operation suited to battery-backed or always-on control nodes. Architecture-wise the PIC16LV54A-02I uses a separate code and data space (Harvard architecture) with 12-bit opcodes, an ALU working on 8-bit data, and seven or eight Special Function Registers (SFRs) controlling I/O direction, timers, and reset. Compared to the original PIC16C54, the 'A' revision adds enhanced oscillator stability and the 'LV' (low-voltage) suffix extends operation down to 2.0 V, making it suitable for 2xAA battery or 3.3 V regulated systems. Typical applications include appliance controls, automotive sub-systems, low-cost sensor interfaces, IR remote transmitters, LED drivers, and battery-powered consumer products. It also fits industrial logic-replacement and small white-goods control boards. A common design tip: provide a decoupling capacitor of 0.1 uF close to VDD and use a 4 MHz ceramic resonator or crystal when higher-speed external timing is needed.

PIC16LV54AT-02I/SS - 0.75KB OTP 8-bit MCU, 2MHz, SSOP-18
PIC16LV54AT-02I/SS

PIC16LV54AT-02I/SS - 0.75KB OTP 8-bit MCU, 2MHz, SSOP-18

The Microchip Technology PIC16LV54AT-02I/SS is an 8-bit EPROM/ROM-based CMOS microcontroller in the PIC16C5X family, delivering 0.75 KB (768 B) of one-time-programmable program memory, 25 bytes of RAM, and 12 I/O pins in a 20-pin SSOP package. The 'LV' suffix denotes a low-voltage variant operating from 3V to 5.5V, while the 'A' suffix marks the enhanced instruction set revision, and the 'T' suffix identifies tape-and-reel packaging. With a 2 MHz maximum clock and 12-bit-wide instructions feeding an 8-bit data path, the device targets cost-sensitive embedded control where ROM-equivalent code storage is acceptable. An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, integrating a CPU core, non-volatile program memory, working RAM, digital I/O, and peripheral blocks such as timers and interrupts on one die. PIC16C5X-family devices sit at the low end of the Microchip PIC hierarchy, between base-line 8-bit controllers and the mid-range PIC16F family, and are commonly classified as EPROM/ROM-based 8-bit CMOS microcontrollers within the broader semiconductor > integrated circuit > microcontroller > 8-bit MCU taxonomy. Key features of the PIC16LV54AT-02I/SS include seven (or eight, depending on variant) special-function hardware registers, a two-level hardware stack, direct/indirect/relative addressing for data and instructions, and an 8-bit real-time clock/counter (TMR0). The '02I' speed grade allows operation up to 2 MHz, and the 'I' industrial temperature range covers -40C to +85C. Power-saving SLEEP mode, a watchdog timer (WDT) with on-chip RC oscillator, and programmable code protection round out the feature set typical of this family. Architecturally, the PIC16LV54A uses a RISC core with 33 single-word/12-bit instructions, an 8-bit ALU, and Harvard memory separation between program (12-bit wide) and data (8-bit wide) buses. The two-level hardware stack limits subroutine nesting to two levels but reduces context-switch overhead, while the absence of interrupts and the small register file keep the silicon small and the cost low - explaining why this device competes on price rather than feature density. Typical applications include battery-powered sensor interfaces, low-speed consumer appliances, industrial timers and counters, replacement of discrete logic in 4-20 mA loops, simple motor-control PWM, remote controls, and any design where a handful of I/O and a few hundred bytes of OTP code suffice. Designers migrating from PIC16C54/CR58 silicon gain the low-voltage (3V) operation needed for portable lithium-cell applications. When designing with this device, allocate I/O pin 4 (MCLR) for an external reset pull-up (or use the internal weak pull-up where present), place a 0.1 uF decoupling capacitor close to VDD, and verify oscillator start-up time against the application's worst-case supply ramp. Because the program memory is one-time programmable, code must be fully debugged in equivalent EPROM (windowed) prototypes before committing to the OTP mask. This page synthesizes distributor pricing, same-family drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, giving procurement and firmware engineers a single authoritative reference for sourcing and substituting the PIC16LV54AT-02I/SS.

PIC17C42A-16/L

PIC17C42A-16/L - 8-Bit 16MHz 4KB OTP MCU 44-PLCC | Microchip

The Microchip Technology PIC17C42A-16/L is a high-performance 8-bit CMOS EPROM/ROM microcontroller built on the PIC17C architecture, delivering up to 16 MHz CPU clock and 4 KB (2K x 16) of One-Time-Programmable (OTP) program memory in a 44-pin PLCC (J-Lead) package. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, RAM, peripherals, and I/O on one silicon die. PIC microcontrollers from Microchip use a RISC-based Harvard architecture where separate program and data buses allow simultaneous instruction fetch and operand access. The PIC17C family sits above the PIC16C line in performance, offering higher MIPS, larger address spaces, and richer peripherals, while remaining code-compatible with the PIC16C5X, PIC12CXXX, and PIC16CXX instruction-set families. Key features of the PIC17C42A include 8.25 MIPS throughput (121 ns instruction cycle), 232 bytes of general-purpose RAM, 33 digital I/O lines, a hardware USART for serial communication, two 8-bit timers plus two 16-bit timers, and a programmable prescaler. The 16 MHz maximum oscillator yields 8.25 MIPS - among the fastest 8-bit PIC devices in production at its introduction. The OTP program memory supports in-circuit programming via Microchip's standard tools, while the EPROM-based die allows prototype reprogramming through a windowed package variant. Architecturally, the PIC17C42A uses a 16-bit-wide instruction word and an 8-bit data path, with a 64 KB linear program address space and 16-level hardware stack. The USART can operate in asynchronous, synchronous master, and synchronous slave modes, supporting standard baud rates up to 625 kbaud at 16 MHz. Brown-out reset, watchdog timer, and power-on reset are integrated. Typical applications include industrial control, instrumentation, motor control front-ends, sensor signal conditioning, embedded communication bridges, and legacy 8-bit upgrades where PIC16C code must scale up without re-architecting. The wide temperature grade (-40C to +85C commercial) also supports white goods and consumer electronics. When designing with this part, verify that your C compiler or assembler targets the PIC17C instruction set; not all PIC tools support PIC17. The 44-PLCC package is through-hole or socket-mountable, simplifying prototypes and field replacement.

PIC17C42A-16/P - 8-Bit OTP MCU, 16MHz, 4KB, 40-PDIP | Microchip
PIC17C42A-16/P

PIC17C42A-16/P - 8-Bit OTP MCU, 16MHz, 4KB, 40-PDIP | Microchip

The Microchip Technology PIC17C42A-16/P is an 8-bit high-performance CMOS EPROM/ROM microcontroller built on the PIC17C architecture and housed in a 40-pin PDIP (0.600", 15.24 mm) through-hole package. It runs at 16 MHz maximum clock input, executes instructions in 121 ns (8.25 MIPS), and integrates 4 KB of OTP program memory (2K x 16) plus 232 bytes of data RAM for embedded control tasks. What is a PIC microcontroller? A PIC microcontroller is a family of RISC-based microcontrollers from Microchip Technology that combine a CPU core, program memory, data RAM, peripherals, and I/O pins on a single CMOS die. PIC microcontrollers sit in the broader hierarchy of microcontroller -> embedded controller -> semiconductor IC, and the PIC17C sub-family specifically targets higher-performance 8-bit designs that need more code space, more I/O, and hardware features beyond what the PIC16C5X and PIC16CXX devices provide. Key features of the PIC17C42A-16/P include 33 digital I/O pins, 2 capture inputs, 2 PWM outputs, 2 x 8-bit plus 2 x 16-bit timers (4 timer modules total), a USART for serial communication, external memory addressing, and external oscillator support. The device is OTP (One-Time-Programmable) for code storage and operates across the standard industrial temperature range of -40C to +85C from a 5 V supply. Architecturally, the PIC17C42A uses a Harvard RISC core with only 58 single-word instructions, an 8-level hardware stack, and interrupt handling suited to demanding real-time control. Compared to the older PIC16C5X, it adds extended instructions, wider addressing, and richer peripherals while remaining source-compatible with the PIC16CXX family, allowing designers to upgrade performance without rewriting firmware from scratch. Typical applications include industrial control systems, motor drive front-ends, smart sensor nodes, embedded instrumentation, and white-goods appliance controllers. The combination of 33 I/O lines and 4 KB of code storage fits mid-range embedded products where deterministic real-time behavior matters. When designing with this part, plan for OTP programming: the program memory cannot be erased, so production code must be fully verified before blow. Use the matching windowed ceramic (JW) variant for prototype development, then move to the OTP "P" package for production builds. Microchip recommends migrating to the PIC18F4220 for new designs, but the PIC17C42A-16/P remains a supported legacy option.
