PIC16F877T-04I/L

PIC16F877T-04I/L - 8-Bit 4MHz 14KB Flash MCU | Microchip 44-PLCC

The Microchip Technology PIC16F877T-04I/L is an 8-bit CMOS flash-based microcontroller from the PIC16F family, operating at up to 4MHz with 14KB (8K x 14 words) of in-system programmable Flash program memory and 368 bytes of RAM, housed in a 44-pin PLCC package. The part is supplied in Tape and Reel packaging (the 'T' suffix) and is rated for the Industrial temperature range (-40C to +85C) as indicated by the 'I' designator. An 8-bit microcontroller (MCU) is a programmable digital integrated circuit that combines a CPU, memory, and peripherals on a single die. The PIC16F family uses Microchip's modified Harvard RISC architecture with 35 single-word instructions and a 14-bit instruction word, executing instructions in 200ns at 20MHz (or 1us at 4MHz for the -04 speed grade). 8-bit MCUs sit at the low-power, low-cost end of the embedded hierarchy: microcontroller -> embedded controller -> semiconductor -> integrated circuit. Key features include a 10-bit 8-channel Analog-to-Digital Converter (ADC), 256 bytes of EEPROM data memory, 33 digital I/O pins, three timers (Timer0, Timer1, Timer2), and serial peripherals including UART/USART, SPI, and I2C (MSSP module). The device supports in-circuit serial programming (ICSP) via two pins, enabling field firmware updates without removing the part from the board. The PIC16F877 architecture uses a 14-bit program word with separate program and data buses, allowing instruction fetch and data access in a single cycle. Its 8-level hardware stack, 25-pin-peripheral architecture, and CCP/ECCP modules (Capture/Compare/PWM) make it suitable for motor-control and timing-sensitive applications. Brown-out Reset (BOR), Power-on Reset (POR), and Watchdog Timer (WDT) provide robustness in industrial environments. Typical applications include industrial automation controllers, sensor signal conditioning, low-power data loggers, HVAC control boards, and educational development platforms. The wide peripheral set and 4MHz operation are sufficient for slow-loop control and human-machine-interface (HMI) tasks. When designing with this MCU, note that Microchip now recommends the PIC16F887 as the newer replacement device. Engineers migrating from PIC16F877 to PIC16F887 gain an internal oscillator, more ADC channels, and nanoWatt power management while retaining pin-out compatibility in many packages. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes that complement - but do not replace - the manufacturer datasheet for the PIC16F877T-04I/L.

The Microchip Technology PIC16F877T-04I/PQ is an 8-bit CMOS FLASH-based PIC microcontroller operating at 4MHz, integrating 14KB (8K x 14 words) of program FLASH memory, 368 bytes of SRAM, and 256 bytes of EEPROM data memory in a 44-pin MQFP (10x10 mm) package. It is the tape-and-reel, industrial-temperature variant of the PIC16F877 family, offering 33 digital I/O pins and a 200 ns instruction execution time across 35 single-word instructions. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (FLASH/ROM), data memory (RAM), non-volatile data storage (EEPROM), and a set of peripherals onto one silicon die. PIC microcontrollers use a RISC Harvard architecture that separates program and data buses, allowing instruction fetch and operand access to occur in the same cycle. Within the broader taxonomy, the PIC16F877 belongs to the PIC16 mid-range family -> 8-bit MCU -> microcontroller -> embedded processor -> semiconductor IC. The 04 speed grade indicates a 4MHz maximum oscillator input. Key features include 14KB self-programmable FLASH, 256 bytes of true EEPROM for data logging, an 8-channel 10-bit ADC, two 8-bit timers plus one 16-bit timer, a synchronous/asynchronous USART, an MSSP module supporting both SPI and I2C, and a capture/compare/PWM (CCP) module. Industrial temperature range of -40C to +85C and brown-out detection support robust embedded designs. The 44-MQFP (Metric Quad Flat Pack) provides a 0.80 mm pitch and 10x10 mm body. Architecturally the PIC16F877 uses a 14-bit instruction word with an 8-bit data path, an 8-level hardware stack, and direct, indirect, and relative addressing modes. The integrated enhanced FLASH cell supports >100K erase/write cycles and >40-year data retention, while the EEPROM supports >1M erase/write cycles. Two capture inputs and a PWM output (10-bit resolution) are accessible via the CCP module. Typical applications include industrial control panels, HVAC sensor nodes, motor control, smart instrumentation, automotive body electronics, and educational embedded platforms where PIC development tools are prevalent. The 44-MQFP variant suits legacy through-hole-friendly layouts and is widely supported by Microchip's MPLAB X IDE and PICkit debug programmers. The newer PIC16F887 family member is recommended for new designs. A critical design consideration is that the -04 speed grade limits operation to 4MHz at the rated Vdd; for designs requiring higher throughput at lower Vdd, the PIC16F877-20 variant (20MHz) should be selected instead. The -I suffix indicates industrial temperature range (-40C to +85C).

PIC16F877T-20/L

PIC16F877T-20/L - 8-bit 20MHz 14KB Flash MCU 44-PLCC | Microchip

The Microchip PIC16F877T-20/L is an 8-bit RISC microcontroller featuring the PIC16 CPU core with 14KB (8K x 14 words) of FLASH program memory, 368 bytes of data RAM, and 256 bytes of data EEPROM, packaged in a 44-pin PLCC (16.59x16.59 mm) and supplied on tape-and-reel. It executes 35 single-word instructions in as little as 200 nanoseconds at 20MHz, providing Microchip's classic mid-range PIC architecture with industry-standard peripheral integration. A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (FLASH for program, SRAM for data, EEPROM for non-volatile storage), and peripherals (timers, ADC, communications, I/O) onto one silicon die. Within the broader taxonomy, the PIC16F877 belongs to the 8-bit microcontroller class, which sits inside the microcontroller family, which in turn is a subset of embedded computing semiconductors. The 8-bit class remains widely deployed where deterministic instruction timing, low cost, and simple toolchain (assembly or C with the MPLAB XC8 compiler) outweigh raw throughput. Key specifications: 20MHz maximum clock, 5V typical operating voltage (range typically 2.0V-5.5V), 33 digital I/O pins, 8-channel 10-bit ADC, USART, MSSP (SPI/I2C), two CCP modules, and a watchdog timer. The 14KB FLASH holds roughly 8K instructions, generous for state machines, sensor aggregation, and human-machine-interface (HMI) controllers. The architecture is built on Harvard memory organization with separate program and data buses, an instruction pipeline, and a 14-bit program word. Brown-out Reset (BOR), Power-on Reset (POR), and the watchdog timer combine to deliver robust in-field recovery without external supervisors. The MSSP peripheral supports both SPI master/slave and I2C master/slave, simplifying bus integration with EEPROMs, sensors, and displays. Typical applications include industrial sensor interfaces, HVAC controllers, automotive body electronics (where the I-grade variant applies), consumer appliance controls, low-cost data acquisition, and educational/hobbyist development. The 8-channel ADC and 33 I/O make it a natural fit for instrumentation front-ends with keypad/LCD user interfaces. A core design consideration is selecting the oscillator mode: crystal/ceramic resonator for timing-critical designs or internal RC mode to save board space. In-system programming (ICSP) via RB6/RB7 pins allows firmware updates without removing the device, but those pins must not be repurposed as outputs during programming.

The Microchip Technology PIC16F877T-20/PQ is a CMOS FLASH-based 8-bit microcontroller from the PIC® 16F family, providing 14KB (8K x 14) of on-chip FLASH program memory, 368 bytes of data RAM, and 256 bytes of EEPROM, housed in a 44-pin MQFP (PQ) package rated for 20MHz operation. The PIC16F877T-20/PQ operates from 4.0V to 5.5V and executes instructions in a 200ns single-cycle pipeline, supporting 33 digital I/O pins, an integrated 10-bit ADC, two USART modules, MSSP (SPI/I2C), two 8-bit and one 16-bit timer, and a parallel slave port. An 8-bit microcontroller (MCU) is a single-chip processor that integrates a CPU, memory, and peripherals on one piece of silicon. PIC microcontrollers use a RISC architecture with only 35 single-word instructions, balancing code efficiency with deterministic timing. Within the broader MCU taxonomy, 8-bit PIC MCUs sit beneath 16-bit PIC24/dsPIC and 32-bit PIC32 families, and are part of the wider embedded microcontroller category that includes AVR, 8051, MSP430, and Cortex-M0 devices. The PIC16F877 family targets peripheral-rich industrial and consumer applications where deterministic I/O handling and low cost matter more than raw CPU throughput. Key features of the PIC16F877T-20/PQ include in-circuit serial programming (ICSP) via two pins, a watchdog timer with on-chip RC oscillator, power-on reset, brown-out detection, and a code-protection bit pattern to lock FLASH contents. Compared with newer PIC16F877A silicon, the original PIC16F877 lacks the extended instruction set and improved ADC performance; Microchip officially recommends migrating to the PIC16F887 for new designs. The RISC-style architecture, 14-bit wide instruction word, and Harvard bus structure allow deterministic, mostly single-cycle execution. With 20MHz oscillator input, the instruction cycle is 200ns, providing 5 MIPS peak throughput - sufficient for control loops, sensor polling, and slow serial communication. The 256-byte EEPROM supports 1M erase/write cycles, and FLASH endures 100K write cycles per cell, making the device suitable for parameter storage and field updates via bootloader or ICSP. Typical applications include industrial control panels, HVAC fan controllers, instrumentation front-ends, security alarm panels, and legacy serial-bus sensor nodes where the 44-MQFP footprint is retained for retrofit boards. Designers also use it for educational platforms and rapid prototyping given the long-standing availability of compilers, debuggers, and reference designs. When designing with the PIC16F877T-20/PQ, ensure the 5V rail is regulated and decoupling is placed at every VDD pin pair. Note that Microchip has migrated most PIC16F877 family devices to the PIC16F877A-A version for new designs; confirm the errata list before finalizing firmware because older silicon may exhibit ADC and LVD behavior differences. This page combines manufacturer datasheet figures, distributor pricing tiers, and parametric drop-in alternatives curated for the PIC16F877 family, providing a single reference for sourcing and BOM decisions.

Typical applications include industrial process control, HVAC and building automation, automotive body electronics (non-safety), instrumentation front-ends, and legacy embedded product replacements. The wide peripheral set also suits sensor hub nodes, motor control loops, and human-machine interface (HMI) controllers using character LCDs. A key design consideration is the obsolete status note from Microchip (recommends PIC16F887 for new designs), but the 44-pin PLCC remains drop-in compatible with the successor family for many footprints. Designers should verify the ICD/debug header compatibility and use MPLAB X IDE with a PICkit or ICD programmer during development.

The PIC16 architecture uses separate program and data memory spaces and is upward compatible with earlier PIC16C5X, PIC12CXXX, and PIC16C7X devices, as stated on the Microchip product page. Its 44-pin MQFP provides a higher I/O count than 40-pin DIP variants, while the 20MHz speed rating supports more demanding timer, serial-interface, and control-loop workloads than 4MHz implementations. Typical applications include industrial monitoring equipment, temperature controllers, motor and relay controllers, data-acquisition front ends, instrumentation, and general-purpose embedded control. The same 44-pin package is also used by newer PIC16F887 devices, which Microchip identifies as a newer device for the PIC16F877 family and which are discussed as having the same pinout in replacement guidance. Designers should verify the exact pin assignment, oscillator configuration, programming interface, and peripheral availability against the manufacturer datasheet before a hardware revision. The -40°C to +85°C industrial temperature range supports deployed equipment, but electromagnetic robustness, watchdog strategy, brownout behavior, and communication timing must still be validated for the end application. This product page combines the verified device specifications, lifecycle information, observed distributor pricing, pin-compatible replacement candidates, and application guidance to provide practical information beyond a basic manufacturer ordering-table entry. Alternative listings remain subject to firmware, peripheral, and qualification review.

PIC16F877T-20I/PT

PIC16F877T-20I/PT - 20MHz 8-Bit MCU | Microchip Technology

The Microchip Technology PIC16F877T-20I/PT is an 8-bit CMOS Flash-based PIC microcontroller operating at up to 20 MHz, with 14 KB (8K x 14 words) of program Flash, 368 bytes of RAM, and 33 I/O pins, housed in a 44-pin TQFP (10 x 10 mm) package. It combines a RISC-based PIC architecture, 200 ns instruction execution, and a 35-instruction instruction set in a compact surface-mount microcontroller. An 8-bit microcontroller is a programmable semiconductor integrated circuit that executes embedded-control instructions using an 8-bit data path. Within the product hierarchy, the PIC16F877 belongs to Microchip’s mid-range PIC16 family, combining general-purpose digital control, Flash program memory, data RAM, and dedicated communication peripherals in one device. The PIC16F877T-20I/PT is therefore more capable than simple 8-bit logic controllers while remaining simpler than many 16- and 32-bit processors. Key features include 14 KB of Flash program memory, 368 bytes of RAM, 33 I/O pins, and a maximum clock frequency of 20 MHz. Its industrial-temperature designation identifies it for extended-temperature equipment, while the -20 suffix specifies the 20 MHz performance grade. According to the manufacturer product page, the core uses a powerful RISC-based PIC architecture with 35 single-word instructions and 200 ns instruction execution, supporting efficient control loops, timing, and serial-interface handling. The integrated feature set supports embedded designs that require multiple I/O lines, asynchronous and synchronous serial communication, timers, interrupts, and programmable digital interfaces. A 44-pin TQFP provides substantially more I/O connectivity than smaller 28-pin and 40-pin microcontroller packages, making the device suitable for controller boards where external logic, sensors, relays, communication transceivers, and human-interface circuitry must connect to one controller. Typical applications include industrial monitoring and control, communication equipment, data acquisition, motor and relay control, instrumentation, and embedded products requiring an extended-temperature 8-bit MCU. The 20 MHz operating speed provides additional timing margin for interrupt-driven control, while 33 I/O pins reduce the need for external I/O expanders. The 14 KB Flash area also allows meaningful embedded code, bootloader logic, and configuration storage within a single device. Designers should verify the exact peripheral mapping, electrical limits, programming requirements, and timing constraints against the manufacturer datasheet before layout release. A 44-pin TQFP footprint requires adequate copper area and careful fan-out for signal integrity and assembly. The industrial grade should be confirmed for every unverified operating-temperature requirement, and firmware should be validated for all interrupt priorities, peripheral interactions, and communication rates. This product data consolidates the verified manufacturer and distributor information, distinguishes package and temperature variants, and identifies where drop-in alternatives require careful compatibility review. It also adds practical comparison and selection guidance that is not normally presented together on a distributor listing, helping engineers assess procurement, PCB reuse, and firmware compatibility more efficiently.

PIC16F87T-E/SS - 8-bit 20MHz 7KB Flash MCU | Microchip

The Microchip Technology PIC16F87T-E/SS is an 8-bit PIC16 microcontroller built on an enhanced RISC architecture, featuring a 20 MHz core clock with 200 ns instruction execution, 7 KB (4K x 14) of Flash program memory, 368 bytes of SRAM, and 256 bytes of EEPROM in a 20-pin SSOP package. Tape-and-reel ("T") and "E" denote the extended (-40C to +125C) industrial temperature range, allowing deployment in harsh environments. The device is built on Microchip's nanoWatt Technology platform for reduced active and sleep power consumption. A PIC microcontroller is a RISC-based 8-bit Harvard-architecture MCU that executes single-word instructions from on-chip Flash memory; the PIC16F family is the canonical mid-range family, bridging the PIC10/12/16 baseline series and the higher-pin PIC18 series. Within Microchip's taxonomy, the PIC16F87 sits at the intersection of nanoWatt low-power MCUs and the PIC16F87x mainstream Flash controllers, offering serial peripherals (I2C, SPI, UART/USART), PWM, and brown-out reset in a small 20-pin package. Key features of the PIC16F87T-E/SS include 16 I/O pins, 35 single-word instructions, an 8 MHz internal oscillator option, an in-circuit debug (ICD) interface, Power-on Reset (POR), Brown-out Detect/Reset, and a Watchdog Timer (WDT) with its own on-chip low-power oscillator. The device operates from 4 V to 5.5 V and supports two power-managed modes - Sleep and Idle - to minimize quiescent current in battery-powered designs. Peripherals include a 10-bit ADC on larger package variants and synchronous/asynchronous serial ports. The architecture is a Harvard-memory CMOS design with separate 14-bit instruction and 8-bit data buses, enabling one instruction per clock cycle at 20 MHz. The Flash memory is programmable via ICSP (In-Circuit Serial Programming), allowing firmware updates without removing the part from the board. This makes the PIC16F87T-E/SS well-suited to prototype-to-production migration on a single PCB layout. Typical applications include industrial sensor interfaces, motor-control PWM drivers, automotive body electronics, consumer white-goods controllers, low-power remote keyless entry (RKE), and general-purpose embedded control. The extended temperature range makes it suitable for under-hood and outdoor equipment. Designers often migrate to this MCU from older PIC16C7x and PIC16C62xA designs because the pinout and core registers are upwards-compatible. When designing with this device, ensure the ICSP pins (RB6/RB7) are not loaded with low-impedance circuits in production, since in-circuit programming requires signal integrity on these lines. Use the configuration bits to set oscillator source, watchdog enable, and code protection, and place a 100 nF decoupling capacitor within 5 mm of VDD.

The Microchip Technology PIC16F87T-I/ML is an 8-bit PIC® microcontroller (MCU) built on Microchip's enhanced mid-range core, featuring 20 MHz maximum clock speed (200 ns instruction cycle), 7 KB (4K x 14) of Flash program memory, 368 bytes of SRAM, and 256 bytes of EEPROM data memory, all housed in a compact 28-pin QFN (6x6 mm) package. The "T" suffix indicates a Tape & Reel packaging option, while the "I" denotes the industrial temperature grade (-40°C to +85°C). This CMOS Flash-based MCU delivers 16 digital I/O pins and integrates the nanoWatt Technology power management feature set, making it suitable for both battery-powered and line-powered embedded designs. What is an 8-bit microcontroller? An 8-bit microcontroller (MCU) is a single-chip computer that processes data 8 bits at a time and integrates a CPU, memory (Flash/ROM for program code, RAM for data, sometimes EEPROM), and peripherals (timers, communication modules, ADC) on one die. The PIC16F87 family sits in Microchip's mid-range PIC® hierarchy: PIC10/12/16/18 family -> PIC16 mid-range -> PIC16F87x enhanced Flash series -> PIC16F87T tape-and-reel sub-line. The QFN-28 (6x6) package places this device in the same footprint family as Microchip's other 28-pin enhanced PICs, enabling layout reuse across the series. Key features include a 14-bit instruction word with only 35 single-word instructions, on-chip brown-out detect/reset (BOR), power-on reset (POR), watchdog timer (WDT), pulse-width modulation (PWM) peripherals, and three serial communication interfaces: I²C, SPI, and USART. The device supports in-circuit serial programming (ICSP) via two pins, allowing firmware updates after PCB assembly without removing the chip. Technical depth: The PIC16F87 architecture uses a Harvard-style memory organization with separate program and data buses, a 15-bit program counter capable of addressing 32K x 14 words, and a 13-bit stack for subroutine nesting. The nanoWatt Technology feature set includes multiple power-managed operating modes (run, idle, sleep) with wake-up on interrupt, an internal oscillator option, and ultra-low power consumption in sleep mode. The device operates across 2.0V to 5.5V VDD, supporting both 3.3V and 5V system designs. Typical applications include industrial control and sensor interfacing, low-power remote sensor nodes, consumer appliance controllers, automotive body electronics subsystems (non-safety), and legacy embedded system upgrades where a proven 8-bit core replaces older PIC16C7x designs. Its broad peripheral set also makes it a fit for simple human-machine interface (HMI) panels with PWM-driven LED or buzzer outputs. Design consideration: When migrating from the older PIC16F87 to the PIC16F87T variant, verify the T suffix means tape-and-reel only (no silicon change) versus other temperature-grade suffixes. Ensure ICSP programming connector access is preserved on the PCB, since debug and firmware updates require PGx and PGx pins to be routed to a header. The 28-QFN has a thermal pad that must be soldered to the ground plane for proper thermal and electrical performance. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes not found in the manufacturer datasheet alone.

A microcontroller (MCU) is a single-chip computer that integrates a CPU, RAM, non-volatile program memory, and a rich set of peripherals. The PIC16F88 sits in the PIC® mid-range 8-bit family — microcontrollers > 8-bit microcontrollers > PIC® mid-range — and historically targets applications that need serial comms, ADC, and PWM in a small footprint. Key features include an internal 8 MHz oscillator (calibrated to ±1% per Microchip datasheet 30487D), seven 10-bit Analog-to-Digital (A/D) converter channels, an Addressable USART for asynchronous serial, a master Synchronous Serial Port (MSSP) configurable as either 3-wire SPI™ or 2-wire I²C™, a Capture/Compare/PWM (CCP) module, a programmable Brown-out Reset (BOR), and an ICD (In-Circuit Debug) interface on pins RB6/RB7. Sixteen I/O pins are available with 25 mA source/sink capability per pin, making it suitable for direct driving of small relays and LEDs. Architecturally, the device uses a 14-bit instruction word, 35 single-word instruction set, and an 8-level deep hardware stack for subroutines.

Typical applications include consumer remote controls, sensor signal conditioning, low-end motor control, RS-232 / RS-485 protocol bridges, hobbyist and educational platforms (replacing the legacy PIC16F84), and small-scale industrial sensor interfaces. The 18-pin PDIP package is specifically chosen for through-hole prototyping, breadboarding, and legacy PCB compatibility. When designing with this part, populate CONFIG words to enable the internal oscillator and disable unused peripherals via firmware, since the MCU consumes active current proportional to oscillator speed. A 0.1 µF decoupling cap between VDD/VSS placed within 5 mm of the pins is mandatory; an internal POR (Power-On Reset) holds the part in reset until VDD reaches a stable threshold.

The Microchip Technology PIC16F88-E/SO is an 8-bit CMOS Flash-based microcontroller in the PIC16F family, featuring 7KB (4K x 14) of program memory, 368 bytes of SRAM, 256 bytes of EEPROM, and 16 digital I/O pins, packaged in a 18-pin SOIC (SO) with 0.295-inch (7.50 mm) body width. The -E temperature grade suffix designates an extended industrial operating range of -40C to +125C, distinguishing it from the standard -I (industrial) and -F (extended) siblings of the same die. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, working RAM, and configurable peripherals. Within the Microchip portfolio, PIC microcontrollers form a 35-instruction RISC architecture family upward-compatible with the legacy PIC16C7x, PIC16C62xA, PIC16C5X, and PIC12Cxxx devices, and sit at the bottom of the modern 8-bit PIC16F/18F hierarchy before scaling into 16-bit dsPIC and 32-bit PIC32 families. Key features include a 20 MHz maximum operating frequency (200 ns instruction cycle), an integrated 8 MHz internal oscillator that eliminates external crystals in many designs, a 10-bit Analog-to-Digital converter with up to 7 channels, a capture/compare/PWM module, and dual configurable serial ports - an Addressable USART plus a Synchronous Serial Port that operates as either 3-wire SPI or 2-wire I2C. The 18-pin SOIC footprint is the most common PIC16F88 package and is interchangeable across the family. Architecturally, the PIC16F88 uses a Harvard structure with separate program and data buses, 14-bit wide Flash instructions, and a hardware stack eight levels deep. The internal 8 MHz oscillator can be calibrated in software using the OSCTUNE register, allowing ±1 percent frequency accuracy without external components. Brown-out Reset, Power-on Reset, and a Watchdog Timer with its own on-chip low-power oscillator are integrated, providing five distinct oscillator modes selectable via configuration fuses. Typical applications include battery-powered sensor nodes, automotive body controllers (when qualified through the -Q1 automotive grade), industrial control panels, and consumer appliances where a small pin count plus rich peripherals reduce external component count. Designers also use the PIC16F88-E/SO in legacy PIC16C7x socket replacements because the peripheral set and pinout are upward-compatible. When migrating between PIC16F87 and PIC16F88, only the enhanced CCP and the added USART capability differ - existing PCB layouts and firmware libraries transfer with minimal rework. Choose -E over -I when the end product is exposed to industrial ambient temperatures above 85 C, and pair the device with a PICkit programmer for in-circuit serial programming via the ICSP pins.

The "E" suffix denotes the extended temperature grade (-40C to +125C), making this part suitable for industrial and harsh-environment deployments beyond the standard "I" grade (-40C to +85C). The SSOP suffix indicates the 5.30 mm body width 20-SSOP surface-mount package. An 8-bit microcontroller (MCU) is a programmable integrated circuit that combines a CPU, memory (Flash/RAM/EEPROM), and peripherals on a single die. MCUs sit at the lowest tier of the embedded computing hierarchy: MCU -> microcontroller -> embedded controller -> semiconductor. The PIC16F88 family belongs to Microchip's mid-range PIC16 architecture, which uses a Harvard-style RISC core with 35 single-word instructions and is upwards-compatible with PIC16C7x, PIC16C62xA, PIC16C5X, and PIC12CXXX devices. Key features include a built-in 8 MHz internal oscillator (eliminating the need for an external crystal in cost-sensitive designs), a 10-bit Analog-to-Digital Converter with up to 7 channels, an Addressable USART, a master Synchronous Serial Port configurable as 3-wire SPI or 2-wire I2C, a Capture/Compare/PWM module, and nanoWatt Technology power management with multiple low-power Sleep modes. The device operates across 2.0 V to 5.5 V supply. Typical applications include industrial sensor interfaces, low-cost motor control, battery-powered remote controls, smart sensor nodes, automotive body electronics (non-safety), consumer white goods, and home-automation peripherals. The wide operating range and integrated peripherals allow designers to minimize external component count, which reduces BOM cost and PCB area. When designing with this part, ensure the in-circuit serial programming (ICSP) interface is accessible for firmware updates, and place the internal oscillator calibration value (OSCCAL register) into the configuration bits to maintain frequency accuracy across temperature. Compared to the legacy PIC16C7x series, the PIC16F88's Flash memory eliminates UV-erase windows and simplifies inventory management.

PIC16F88-I/ML - 20MHz 8-Bit Flash MCU | Microchip Technology

The Microchip Technology PIC16F88-I/ML is a 20 MHz, 8-bit CMOS Flash microcontroller with 7 KB of program memory, 368 bytes of RAM, 256 bytes of EEPROM, and 16 I/O pins in a 28-QFN package measuring 6 mm by 6 mm. According to the verified distributor data, it integrates a 10-bit, 7-channel analog-to-digital converter, an addressable USART, a synchronous serial port configurable for SPI or I2C, and PWM-capable capture/compare hardware. A microcontroller is a programmable integrated circuit that executes firmware, reads sensors, controls outputs, and coordinates embedded-system peripherals. Within the semiconductor hierarchy, the PIC16F88 belongs to Microchip's PIC16 family of 8-bit microcontrollers, Flash-based embedded controllers, and general-purpose semiconductor devices. Its compact package and mixed analog, digital, timing, and communications resources suit small control systems that need local sensing and actuator management. The verified specifications identify a maximum clock rate of 20 MHz, 4K by 14 words of Flash program memory, 368 bytes of RAM, 256 bytes of EEPROM data memory, and 16 I/O pins. An 8 MHz internal oscillator is listed on the Microchip product page, providing a clock source for applications that do not require an external crystal. The Flash architecture permits in-circuit reprogramming, while EEPROM supports nonvolatile parameter retention between power cycles. The PIC16F88 combines seven 10-bit ADC channels with an addressable USART and a synchronous serial interface supporting three-wire SPI or two-wire I2C operation. Capture/compare/PWM resources support timing and proportional control tasks. This peripheral mix reduces the need for external conversion or interface ICs when the design uses compatible sensors, displays, actuators, or serial transceivers. Typical embedded uses include industrial sensing modules, compact motor controllers, instrument interfaces, environmental monitors, and low-cost connected-control products. The 28-QFN package favors dense surface-mount layouts, but exposed-pad soldering, thermal management, and pin escaping require careful PCB design. Verify the exact package drawing and pin assignment against the manufacturer datasheet before layout release. For firmware development, use the PIC16 mid-range toolchain and confirm programming, clock, peripheral, and package constraints against the selected device documentation. The I/ML ordering code identifies the industrial temperature grade and ML package, but the supplied search data does not state the numeric temperature limits, supply voltage, ADC reference details, or electrical current ratings. Those values must be taken directly from the applicable Microchip datasheet rather than inferred. This page consolidates verified manufacturer and distributor facts, package details, application guidance, and procurement links. It also separates explicitly verified information from missing engineering data, helping engineers locate the PIC16F88-I/ML without relying on assumed specifications or unsupported drop-in substitutions.

PIC16F88-I/P - 8-bit 20MHz MCU 7KB Flash DIP-18 | Microchip

The Microchip Technology PIC16F88-I/P is an 8-bit PIC16 family Flash microcontroller based on the enhanced mid-range architecture, delivering 20 MHz (200 ns instruction cycle) performance in a through-hole 18-pin PDIP package. The device integrates 7 KB (4K x 14 words) of self-programmable Flash program memory, 368 bytes of SRAM, and 256 bytes of EEPROM data memory. It features the Microchip nanoWatt power-managed core with multiple oscillator modes including an internal 8 MHz oscillator. A microcontroller (MCU) is a single-chip computer that integrates a CPU, program and data memory, peripherals, and I/O on one IC. The PIC16F88 sits within the Microchip PIC16 mid-range family, which forms part of the broader 8-bit microcontroller category alongside competing 8051, AVR and STM8 architectures. The PIC16 mid-range lineage is one of the most widely deployed 8-bit cores ever shipped, prized for its small footprint, low power, deterministic instruction set of 35 single-word instructions, and upwards compatibility with the PIC16 baseline and PIC18 families for code portability. Key features of the PIC16F88-I/P include 16 digital I/O pins, a 10-bit ADC with up to 7 input channels, an Enhanced Capture/Compare/PWM (ECCP) module, an Addressable USART (AUSART), and a Master Synchronous Serial Port (MSSP) configurable as SPI or I2C (master/slave). Two 8-bit timers plus one 16-bit timer provide flexible timing, while the nanoWatt feature set delivers reduced power consumption through sleep modes, oscillator switching, and on-the-fly clock source changes. The PIC16F88 is built on a CMOS process and runs from 2.0 V to 5.5 V across the industrial -40 C to +85 C temperature range (denoted by the "-I" suffix). The device is supported by Microchip's MPLAB X IDE, the XC8 C compiler, and the free MPASM assembler, with extensive application notes, firmware libraries, and development boards (PICDEM, Curiosity) shortening design cycles. Typical applications include sensor signal conditioning, motor control with PWM, industrial control panels, low-power battery sensor nodes, home appliance control boards, and serial-port-centric embedded products leveraging the integrated USART. The wide operating voltage and on-chip peripherals make the PIC16F88 a strong fit for retrofits of legacy designs that need modern features without abandoning the familiar PIC16 ecosystem. When designing with this part, ensure the in-circuit serial programming (ICSP) pins (RB6/RB7) and the MCLR pin are routed correctly for production programming and in-field firmware updates. The internal 8 MHz oscillator is calibrated at the factory, but for time-critical UART or PWM applications use an external crystal on OSC1/OSC2 for higher accuracy.
