PIC16LF876A-I/SP - 8-Bit MCU, 14KB Flash, 28-SPDIP | Microchip

The Microchip Technology PIC16LF876A-I/SP is an 8-bit RISC flash microcontroller (MCU) with 14KB (8K x 14) of program memory and 368 bytes of RAM, packaged in a 28-pin SPDIP (0.300", 7.62mm) through-hole DIP. It runs at up to 10MHz internal clock (20MHz oscillator) from a 2.0V-5.5V supply and provides 22 digital I/O pins plus integrated peripherals including a 10-bit ADC (5 channels), 2 comparators, PWM modules, USART, MSSP (SPI/I2C), and a 256-byte EEPROM data memory. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, working RAM, and peripheral interfaces. The PIC16LF876A-I/SP belongs to Microchip's PIC16 family of mid-range 8-bit MCUs, which sit within the broader taxonomy of PIC microcontrollers -> 8-bit microcontrollers -> microcontrollers -> embedded processors -> semiconductors. The "LF" prefix denotes the low-voltage variant (2.0V min VDD vs 4.5V for the standard F part), making it suitable for battery-powered and 3.3V designs. Key features include 200 ns instruction execution across 35 single-word instructions, brown-out reset (BOR), power-on reset (POR), watchdog timer (WDT), in-circuit serial programming (ICSP), and an in-circuit debugger (ICD) interface. The MSSP peripheral supports both SPI master/slave and I2C master/slave modes, while the enhanced USART enables RS-232/RS-485 links. The capture/compare/PWM (CCP) module supports one capture input, one compare output, and one PWM output. Architecturally, the PIC16LF876A uses a Harvard RISC core with separate program and data buses, 14-bit wide instructions, and a 2-stage pipeline. The 8-level deep hardware stack and 32-byte register file give it deterministic interrupt response, which is valuable in real-time control loops. Self-programming capability allows field firmware updates without removing the device from the board. Typical applications include industrial sensor interfaces, low-power data loggers, appliance control boards, automotive body electronics (non-safety), battery chargers, and small-scale motor control. The wide operating voltage range (2.0V-5.5V) and low power consumption make it a strong fit for portable and battery-backed systems. When designing with this MCU, allocate the ICSP pins (RB6/RB7) carefully - they are shared with digital I/O and must be accessible to a programming header. Use a 100 nF decoupling capacitor within 5 mm of VDD and consider a bulk capacitor on the MCLR/VPP line for stable in-circuit programming. The LF variant has tighter timing constraints above 4V and below 3V - consult the datasheet's oscillator and electrical characteristics tables when running at voltage extremes.

PIC16LF876AT-I/ML - 8-Bit 10MHz 14KB Flash MCU | Microchip

The Microchip Technology PIC16LF876AT-I/ML is a low-power CMOS 8-bit Flash microcontroller from the PIC16F876A family, delivering 10 MIPS performance through a 20 MHz oscillator with 4x PLL disabled, housed in a 28-pin QFN (ML) 6x6 mm package with exposed pad. It integrates 14KB (8K x 14 words) of self-programmable Flash program memory, 368 bytes of SRAM, and 256 bytes of EEPROM data memory, all accessible through 22 general-purpose I/O lines. The "A" suffix marks the enhanced Flash variant; the "T" band designates tape-and-reel packaging for high-volume SMT assembly. An 8-bit PIC microcontroller is a RISC (Reduced Instruction Set Computing) device built on Harvard architecture, where program and data buses are physically separate, allowing simultaneous instruction fetch and operand access. The PIC16F family belongs to Microchip's mid-range 8-bit MCU portfolio, sitting above the baseline PIC10/12/16 baseline cores and below the enhanced PIC18 and 16-bit dsPIC/PIC24 families. Mid-range PIC MCUs typically execute one instruction per clock cycle (4 clocks per instruction at the oscillator input), giving 5 MHz oscillator = 1.25 MIPS, 10 MHz = 2.5 MIPS, while this LF part supports up to 200 ns instruction execution at 20 MHz = 10 MIPS. Key features of the PIC16LF876AT-I/ML include a 10-channel 10-bit ADC, two 8-bit timers plus one 16-bit timer, a USART with addressable TX/RX, a Master Synchronous Serial Port (MSSP) supporting both SPI and I2C master/slave modes, two capture/compare/PWM (CCP) modules, an 8-bit parallel slave port, and a 256-byte EEPROM with 1M erase/write cycles endurance. The "LF" prefix designates the wide-voltage low-power variant operating from 2.0 V to 5.5 V, making it compatible with both 3.3 V and 5 V rails. The 28-QFN package is ideal for space-constrained designs and benefits from the exposed thermal pad for improved heat dissipation at full 10 MHz operation. Typical applications span industrial automation sensor interfaces, low-power battery-driven remote controls, automotive body electronics subsystems (non-safety), white-goods control boards, HVAC thermostats, and small appliances. The 10-bit ADC and CCP/PWM peripherals make it well suited for closed-loop motor control, LED dimming, and analog sensor conditioning. When designing with this device, ensure the exposed pad (pin 28 EPAD) is soldered to a properly grounded copper pour; failure to do so risks exceeding the package's thermal budget at high toggling rates.

The Microchip Technology PIC16LF876AT-I/SO is a low-power 8-bit PIC microcontroller based on the mid-range 14-bit RISC architecture, operating at up to 10 MHz instruction rate and packaged in a 28-pin SOIC (SO) wide-body IC. It integrates 14 KB (8K x 14 words) of Flash program memory, 368 bytes of RAM, 256 bytes of EEPROM data memory, 22 digital I/O pins, and a 10-bit multi-channel Analog-to-Digital Converter, making it a strong fit for low-power embedded control. A PIC microcontroller (MCU) is a self-contained single-chip computer built around a CPU, program memory, data memory, and on-chip peripherals. The PIC16 family uses Microchip's enhanced mid-range 14-bit instruction set, which provides only 35 single-word instructions yet delivers 200 ns instruction execution time at 20 MHz. Within the broader taxonomy, the PIC16F876A belongs to the 8-bit microcontroller class -> RISC microcontroller -> embedded microcontroller -> integrated circuit. The "LF" prefix indicates a wide-voltage part supporting 2.0V to 5.5V operation, while the "A" suffix marks the silicon revision that adds self-programmability, an ICD debug port, two analog comparators, two Capture/Compare/PWM modules, and a USART/SCI port configurable as 3-wire SPI or I2C. Key features include five 10-bit ADC channels, two comparators, two CCP modules, one USART, one MSSP (SPI/I2C), 256 bytes of EEPROM, an in-circuit debugger (ICD), Flash self-programming, and wide operating voltage from 2.0V to 5.5V. The instruction set is upward compatible with all PIC16 mid-range parts, so code migrates cleanly to PIC16F873A/874A/877A variants with more memory. The "T" suffix indicates tape-and-reel packaging for high-volume assembly. Technically, the PIC16LF876A combines Harvard architecture (separate program and data buses) with a powerful 14-bit instruction word that improves code density over 8-bit CISC cores. The 368-byte RAM supports a hardware stack 8 levels deep, and the Flash program memory is rated for 100K erase/write cycles. The peripheral set targets embedded sensing and control: five ADC channels cover most analog sensor interfaces, while the MSSP and USART handle asynchronous serial, SPI, and I2C communication with on-chip EEPROM for parameter storage. Typical applications include industrial sensor interface boards, battery-powered handheld instruments, automotive body controllers, low-cost HVAC thermostats, and consumer appliance controllers. The wide 2.0V-5.5V range also makes the LF version attractive for 2-cell battery or 3.3V regulated rails. Use the "A" revision whenever self-programming or in-circuit debug is required; use the original PIC16F876 only when migrating legacy firmware that does not need self-programming. When designing with the PIC16LF876A, ensure MCLR is tied to VDD through a 10kΩ resistor, decoupling caps are placed within 1 cm of VDD/VSS, and the ICSP/ICD pins are reserved for programming header access. The 28-SOIC wide-body package (0.295 inch, 7.50 mm) eases hand-soldering and rework compared to SSOP/QFN packages.

The PIC16LF876 employs a Harvard architecture with separate program and data buses plus a 14-bit wide instruction word, allowing most instructions to execute in a single cycle. This RISC instruction set comprises only 35 single-word instructions, accelerating firmware development and code density relative to CISC MCUs. Typical applications include industrial control panels, sensor signal conditioning, low-power remote sensor nodes, HVAC thermostat controllers, automotive body electronics (non-safety), and consumer appliance control. The 28-pin SOIC footprint simplifies hand prototyping and rework, while the in-circuit debug capability accelerates firmware iteration cycles. When designing with this device, ensure the ICSP programming pins (RB6, RB7) are accessible on the PCB for field updates. The configuration bits (fuses) must be set correctly to enable the internal oscillator or external crystal mode; an unset config word leaves the device in an undefined clock state that can prevent normal operation.

Peripherals include a 10-bit ADC, two 8-bit and one 16-bit timers, capture/compare/PWM modules, USART, MSSP (SPI/I2C), and PSP. An 8-bit microcontroller is a single-chip computer whose arithmetic logic unit, registers, and data bus all operate on 8-bit words; the PIC16 family from Microchip uses a Harvard RISC architecture with separate program and data buses, 35 single-word instructions, and a two-stage pipeline that completes most instructions in four clock cycles. The 'LF' variant specifies an extended low-voltage process (down to 2.0 V), the '04' suffix denotes the 4 MHz speed grade, and the 'P' package code identifies the 40-pin PDIP. This family occupies the 'mid-range' tier of Microchip's 8-bit portfolio, sitting above the PIC12 baseline and below the PIC18 enhanced family. Key differentiating features include the nanoWatt power management modes (sleep, idle, and on-the-fly oscillator switching) and the ICD (In-Circuit Debugger) interface that lets developers use MPLAB tools for non-intrusive debugging.

It executes instructions at 4 MHz (200 ns instruction cycle) and is housed in a 44-pin MQFP (10x10 mm) surface-mount package with industrial temperature grade (-40C to +85C). A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (Flash/RAM/EEPROM), and peripherals (ADC, timers, communication interfaces) onto one die. The PIC16LF877 belongs to the mid-range PIC family, which sits between the baseline PIC10/12/16/17 families and the high-performance PIC18/PIC24/dsPIC families. The LF variant runs from a reduced-voltage rail (2.0-5.5V), making it a low-power derivative of the standard PIC16F877 aimed at battery-powered systems. Key features of this device include 33 digital I/O lines, 8 channels of 10-bit Analog-to-Digital Conversion (ADC), 2 analog comparators, a Capture/Compare/PWM (CCP) module plus an Enhanced CCP module, 3 timers, a USART with addressable SPI/I2C mode, and a parallel slave port. CMOS technology ensures low static and dynamic power consumption across the full industrial temperature range.

PIC16LF877-04I/PT - 8-bit MCU 4MHz 14KB Flash 44-TQFP | Microchip
PIC16LF877-04I/PT

PIC16LF877-04I/PT - 8-bit MCU 4MHz 14KB Flash 44-TQFP | Microchip

The Microchip Technology PIC16LF877-04I/PT is an 8-bit RISC microcontroller from the PIC16F family, featuring a 4 MHz maximum operating frequency, 14 KB (8K x 14) of FLASH program memory, 368 bytes of SRAM, and 256 bytes of EEPROM data memory, all packaged in a 44-pin TQFP (10x10 mm) surface-mount form factor. As the "LF" variant, this part operates across a wide supply range of 2.0V to 5.5V, making it well-suited for both 3.3V and 5V systems, while the "-04" speed grade denotes the 4 MHz instruction execution oscillator limit and the "I" suffix indicates the -40C to +85C industrial temperature range. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, data memory, and peripheral interfaces onto one piece of silicon. Within the broader semiconductor taxonomy, the PIC16LF877 belongs to the 8-bit MCU class, which itself sits inside the embedded microcontroller category of integrated circuits. MCUs are the foundational building blocks of embedded systems, executing deterministic firmware that interfaces with sensors, actuators, communication PHYs, and human-machine interfaces. The PIC16F architecture is Microchip's mid-range 14-bit instruction set, balancing code density, ease of use, and cost, and has shipped in billions of units across automotive, industrial, and consumer applications. The PIC16LF877-04I/PT integrates a rich peripheral set: a 10-bit multi-channel analog-to-digital converter (ADC), a Capture/Compare/PWM (CCP) module, an enhanced CCP, two 8-bit and one 16-bit timers, a synchronous serial port configurable for SPI or I2C, a USART with 9-bit address support, a parallel slave port, and a PSP (Parallel Slave Port). It exposes 33 digital I/O pins across five ports (PORTA-PORTE) with individually programmable weak pull-ups and interrupt-on-change capability. An integrated brown-out detect (Brown-out Reset), power-on reset, watchdog timer with its own on-chip low-power RC oscillator, and in-circuit serial programming (ICSP) further reduce external component count and BOM cost. Architecturally, the PIC16LF877 employs a Harvard RISC core with a 14-bit program word and separate program/data buses, allowing simultaneous instruction fetch and operand access. The 35 single-word instruction set executes in one instruction cycle (200 ns at 20 MHz, or 1 us at 4 MHz for this -04 speed grade), delivering deterministic timing that simplifies real-time control loops. The 8-level deep hardware stack and 2K x 14 word FLASH enable substantial firmware size, while the dual-data-pointer C compiler-friendly architecture eases migration to higher-tier PIC18 or dsPIC devices. Typical applications for the PIC16LF877-04I/PT span industrial automation controllers, building automation sensor nodes, low-speed motor control (brushed DC, small steppers), white-goods user interfaces, simple sensor signal conditioning, RS-232/RS-485 protocol bridges, LED driving boards, and battery-powered remote data acquisition terminals. Its wide voltage range and industrial temperature grade make it equally comfortable in 5V legacy industrial systems and modern 3.3V mixed-signal designs. Designers should note that the -04 speed grade limits the external oscillator input and instruction throughput to 4 MHz; if higher throughput is required, the -20 (20 MHz) variants are drop-in compatible at the same TQFP-44 footprint. Also, the 33 I/O rating excludes any I/O used by the parallel slave port, ADC analog inputs, or external memory interface, so firmware pin allocation must be planned against actual electrical loads and the configured peripheral mix. This page consolidates distributor pricing, same-package drop-in upgrade paths, and engineering context beyond the bare datasheet, enabling faster PIC selection and substitution decisions.

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.

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.

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.

Key features of the PIC16LF877T-04I/L include its nanoWatt technology for low-power operation with multiple power-managed modes (Run, Idle, Sleep), an integrated 10-bit A/D converter with up to 8 channels, two 8-bit timers plus one 16-bit timer, a Capture/Compare/PWM (CCP) module, MSSP for I2C/SPI, and an enhanced USART. The 'LF' prefix denotes the low-voltage variant rated 2.0V-5.5V, and the 'I' suffix marks the industrial temperature grade. The PIC16LF877T-04I/L uses a 14-bit instruction word and offers self-programmable FLASH with ICD (In-Circuit Debugger) support. Its 33 I/O pins are individually configurable with weak pull-ups, interrupt-on-change capability, and source/sink current capability suited to LED driving. The industrial -40°C to +85°C range and wide supply voltage make it well-suited for factory, automotive aftermarket, and consumer appliance environments. Typical applications include industrial automation control boards, HVAC sensor interfaces, low-power remote sensor nodes, consumer appliance front panels, and automotive aftermarket accessories. The 14KB FLASH accommodates substantial application code while leaving room for bootloaders and user-configurable parameters stored in 256-byte EEPROM. When designing with this part, plan decoupling with a 100 nF ceramic capacitor close to VDD and a 10 µF bulk capacitor; use the on-chip PLL-free oscillator or an external crystal to drive the 4 MHz core. For noisy environments, enable the watchdog timer and unused I/O pin output-low to minimize quiescent current.

It is the tape-and-reel, industrial temperature grade variant of the PIC16LF877 family, offering 33 digital I/O lines and a peripheral set including I2C, SPI, and UART/USART. An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path and integrated CPU, memory, and peripherals. PIC microcontrollers use a Harvard RISC architecture with separate program and data buses, enabling single-cycle instruction execution. The PIC16F family targets mid-range embedded applications (appliance control, industrial sensing, sensor hubs) and sits within the broader PIC mid-range hierarchy: 8-bit MCU -> PIC16 family -> PIC16F8xx sub-family -> PIC16LF877 device. The "LF" prefix denotes the low-voltage (2.0V-5.5V) variant suited to battery-powered and 3.3V designs. Key features include 14 KB of self-programmable Flash, 8-channel 10-bit ADC, two analog comparators, a 16-bit capture/compare/PWM module, two 8-bit timers, and a watchdog timer with its own on-chip RC oscillator. The wide operating voltage range of 2.0V to 5.5V makes the device compatible with both 3.3V and 5V rails, while the industrial -40C to +85C temperature range supports outdoor, automotive cabin, and factory-floor deployments. Architecturally, the PIC16LF877T-04I/PQ is built on Microchip's enhanced mid-range core with a 14-bit instruction word and 8-level deep hardware stack.

The 4 MHz rating refers to the maximum oscillator frequency at 5V; at lower VDD the device is typically clocked at lower frequencies to stay within the parametric envelope. Typical applications include industrial sensor interfaces, motor-control front ends, HVAC thermostats, battery-powered data loggers, and legacy embedded control boards. The rich peripheral mix supports mixed-signal designs where the MCU performs ADC acquisition, PWM drive, and serial communication in a single chip. Designers should pair the MCU with a decoupling network of 100 nF + 10 uF near VDD, route MCLR with a proper reset circuit, and verify the oscillator configuration bits against the chosen crystal. The 04 speed grade limits the oscillator to 4 MHz, ensuring parametric margin across voltage and temperature.

It integrates 368 bytes of RAM, 256 bytes of EEPROM, 16 digital I/O pins, and three timer modules (Timer0/1/2) with Capture/Compare/PWM, a 10-bit ADC with up to 8 channels, and a full-duplex USART/SCI plus I2C and SPI interfaces. 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 10-bit, 8-channel successive-approximation ADC delivers roughly 30 kSPS at 5 V, with selectable reference sources including an internal bandgap. Programmable weak pull-ups and interrupt-on-change on PORTB ease human-interface and keypad design, while the synchronous serial port supports both I2C master/slave and SPI master/slave protocols without external glue logic. 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.

PIC16LF88-I/ML - 8-bit MCU, 7KB Flash, 368B RAM | Microchip

The Microchip Technology PIC16LF88-I/ML is a low-power 8-bit CMOS Flash microcontroller from the PIC16 mid-range family, delivering 7KB of program memory, 368 bytes of RAM and 256 bytes of EEPROM, in a 28-lead QFN package (ML suffix). It is built around a RISC architecture that executes most instructions in a single 200 ns cycle, providing up to 5 MIPS throughput when clocked at 20 MHz. 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. Key features include 10-bit ADC with up to 7 channels, a 10-bit PWM module, two 8-bit timers plus one 16-bit timer, a USART with LIN support, an MSSP module for SPI/I2C, an internal 8 MHz oscillator (31 kHz to 8 MHz selectable), and 16 digital I/O pins with individual interrupt-on-change capability. 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.

PIC16LF88-I/P

PIC16LF88-I/P - 8-Bit 10MHz 7KB Flash MCU 18-PDIP | Microchip

The Microchip Technology PIC16LF88-I/P is a low-power CMOS Flash-based 8-bit microcontroller in the PIC16 mid-range family, offering 10 MHz CPU performance, 7 KB (4K x 14) of Flash program memory, 368 bytes of SRAM, and 256 bytes of data EEPROM in a 18-pin PDIP through-hole package. The "LF" suffix indicates an extended low-voltage variant operating from 2.0 V to 5.5 V, while the "I" suffix specifies the industrial -40 C to +85 C temperature range and the "/P" suffix indicates the PDIP-18 package. 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. This page synthesizes distributor pricing, drop-in alternatives, application guidance, and design notes for the PIC16LF88-I/P that go beyond what the manufacturer datasheet alone provides, helping embedded engineers evaluate sourcing options and accelerate board bring-up.
