Detailed Description

PIC16F76 is an 8-bit Flash microcontroller in the PIC16 family. It uses Microchip’s mid-range 14-bit core, supports up to 20 MHz system clock (up to ~5 MIPS), and includes on-chip Flash program memory, SRAM, and data EEPROM. It integrates timers, ADC, PWM/CCP, serial communications, watchdog, brown-out reset, and low-power sleep features. It is commonly offered in 28-pin packages (PDIP-28, SOIC-28, SSOP-28). Category: Integrated Circuits (ICs). Subcategory: Specialized ICs (Microcontrollers). Current stock available: 2300 units. Provided package/case code: 1057.

Key Features

8-bit PIC16 mid-range CPU, 14-bit instruction word, hardware stack

Flash program memory (typical family value up to 8K words)

SRAM data memory (typical family value around a few hundred bytes)

Data EEPROM (typical family value up to 256 bytes) for non-volatile storage

Up to 20 MHz external oscillator; internal oscillator options depending on variant

Timers: Timer0 (8-bit), Timer1 (16-bit), Timer2 (8-bit with prescaler/postscaler)

Capture/Compare/PWM (CCP) modules for precise timing and motor control

10-bit ADC with multiple analog input channels

MSSP (SPI/I2C) for synchronous serial communication

Optional USART/EUSART availability depending on exact sub-variant and pinout

Watchdog Timer, Power-on Reset, Brown-out Detect, Low-Power Sleep

Wide operating voltage range typically from 2.0 V to 5.5 V

Industrial temperature range options (commonly -40°C to +85°C)

Key Advantages

Cost-effective microcontroller with a strong set of peripherals

Low power consumption with sleep and brown-out features for battery-powered designs

Simple programming and robust toolchain support (MPLAB X, XC8)

Flexible I/O and serial interfaces for quick integration

Broad ecosystem, extensive documentation, and community support

Packaging

Package types

- PDIP-28 (through-hole). Molded epoxy body, copper lead-frame, lead-free matte tin plating. Ideal for prototyping and sockets.

- SOIC-28 (surface-mount). Molded epoxy body, gull-wing leads. Good balance of size and ease of assembly.

- SSOP-28 (surface-mount, fine pitch). More compact footprint for space-constrained designs.

Size guidelines (approximate)

- PDIP-28: 600 mil body width; suitable for standard perfboard and sockets

- SOIC-28: ~7.5 mm body width; standard SMT footprint

- SSOP-28: ~5.3 mm body width; fine-pitch SMT footprint

Pin configuration (typical 28-pin PIC16F7x mapping)

- Power and clock: VDD, VSS, MCLR/VPP, OSC1/CLKIN, OSC2/CLKOUT

- Ports: RA0–RA4 (analog-capable pins on some), RB0–RB7 (interrupt-on-change on RB), RC0–RC7

- Peripherals mapped to pins: CCP1/CCP2, SPI/I2C (SCK/SCL, SDI/SDA, SDO), ADC inputs, TX/RX (if USART present)

Thermal characteristics (general guidance)

- PDIP: higher thermal resistance, more mass; good for prototypes and low-to-moderate dissipation

- SOIC/SSOP: lower thermal resistance than PDIP; better heat transfer through PCB copper

- Use solid ground planes and thermal vias for improved heat dissipation

Electrical properties (typical family behavior)

- Operating voltage: ~2.0–5.5 V

- CPU speed: up to 20 MHz external clock (instruction cycle = Fosc/4)

- I/O drive: digital pins can source/sink moderate current; observe per-pin and per-port current limits from datasheet

- Low power modes: sleep current in microamp range depending on configuration

- Brown-out and watchdog improve reliability in noisy or unstable power environments

Note on package/case code 1057

- 1057 is an internal or catalog case reference. For exact mechanical drawing and ordering suffix (e.g., -I/P for PDIP, -I/SO for SOIC), please confirm with our sales team or the official datasheet.

Lifecycle

Status

- Mature, widely used PIC16 device. Not currently flagged as near end-of-life by Microchip at the time of writing. Microchip maintains long-term support for PIC16 families.

Equivalent or alternative models (compare pinouts and peripherals carefully)

- PIC16F876A: 28-pin, very close feature set, EUSART available, widely used and well supported

- PIC16F886: 28-pin enhanced PIC16 with more peripherals, improved ADC, and modern power features; strong upgrade path

- PIC16F1936/PIC16F1937: 28-pin XLP devices with enhanced peripherals (MSSP, EUSART, more timers), very low power

- PIC16F1788: 28-pin with advanced analog (op-amps, DACs), suitable for mixed-signal designs

- PIC16F727: 28-pin PIC16F7x family variant; check LCD driver feature set and pinout if relevant

- PIC18F2520/PIC18F25K22: 28-pin higher-performance PIC18 alternatives for more memory and faster execution
