PIC16F676T-I/ST - 8-bit 20MHz 1.75KB Flash MCU | Microchip TSSOP-14
MPN: PIC16F676T-I/ST ✓ فعالPIC16F676T-I/ST جائزہ
A microcontroller (microcontroller unit, MCU) is a single-chip computer containing a CPU core, Flash/ROM program memory, data RAM, peripherals, and I/O. It is a hypernym under the broader hierarchy of microprocessor -> embedded controller -> microcontroller -> semiconductor. 8-bit MCUs like the PIC16F676 are widely used for cost-sensitive, deterministic, low-power embedded control tasks where 32-bit performance is unnecessary and a small footprint is preferred.
Key differentiating features include 8 channels of 10-bit ADC, 12 I/O pins, an internal oscillator, a comparator module, and a wide operating voltage range from 2.0 V to 5.5 V. The device includes power-managed modes (sleep with <1 µA typical current), in-circuit serial programming (ICSP), and a 64-byte EEPROM data space for non-volatile parameter storage. The industrial-grade "-I" temperature range of -40 °C to +85 °C makes it suitable for harsh environments.
Architecturally, the PIC16F676 uses a Harvard RISC design with separate program and data buses. This separation enables single-cycle instruction fetch alongside data access, improving throughput versus von Neumann architectures at the same clock rate. The Flash-based program memory supports 100K erase/write cycles typical, and the on-chip debug via ICSP allows real-time in-circuit emulation without expensive emulators.
Typical applications include sensor signal conditioning (using the on-board 10-bit ADC), battery-powered consumer devices (leveraging sleep current under 1 µA), small motor and relay control, low-end digital signal conditioning, and standalone product modules in industrial automation. The 14-pin TSSOP footprint is footprint-compatible with several PIC16F630/676/88x family members, allowing PCB reuse.
Design tip: when using the internal oscillator, calibrate at 25 °C to maintain frequency accuracy, and always decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of the IC pin. For ADC readings, add a 10 µF + 100 nF bulk/decoupling combination near AVIN if used, and allow 10 µs acquisition time for accurate conversions.
This page synthesizes distributor pricing, drop-in alternatives in the same TSSOP-14 footprint, and practical design notes not found in the standalone datasheet, helping engineers select and source this part faster.

Battery-Powered Sensor Node
The PIC16F676T-I/ST's 2.0 V to 5.5 V supply range and sub-1 µA sleep current make it well-suited for battery-powered sensor nodes such as remote temperature loggers and wireless HVAC transmitters. The integrated 8-channel 10-bit ADC reads thermistor or voltage-divider sensor outputs directly, while the 64-byte RAM supports small protocol buffers and 128-byte EEPROM stores calibration constants across power cycles. Power-saving design uses the PIC16F676 sleep mode waking on watchdog timer or external interrupt. The TSSOP-14 package fits easily inside a CR2032 coin-cell sensor housing, and Microchip's ICSP allows in-field firmware updates via a 2-pin header without disassembling the device.

Industrial Control Logic Module
In industrial control panels the PIC16F676T-I/ST replaces discrete logic ICs with a programmable 8-bit core, executing deterministic firmware in 200 ns cycles for relay sequencing, indicator lamp driving, and alarm handling. The 12 I/O pins control up to 12 discrete loads, while the comparator module detects threshold crossings on analog inputs such as pressure transducer bridges. Industrial temperature grade (-40 to +85 °C) supports factory-floor operation, and the TSSOP-14 footprint allows through-hole emulation on a daughter board. Microchip's PICkit programmer and MPLAB X IDE provide a full debug environment, with ICD support via ICSP for in-circuit breakpoints during commissioning.

Automotive Interior Lighting Controller
The PIC16F676T-I/ST drives PWM-controlled LED strings for automotive interior ambient lighting, reading potentiometers or capacitive touch sensors via the 10-bit ADC to adjust brightness curves. The 20 MHz clock divides down to generate smooth PWM frequencies above 100 Hz, eliminating flicker perception, and the 8 ADC channels scan multiple independent zones. Sleep current below 1 µA extends battery life when the vehicle is parked. The industrial temperature grade handles cabin thermal extremes, and ICSP programming supports tier-1 OEM end-of-line calibration. The TSSOP-14 fits within the tight confines of a door-panel LED driver PCB.

Consumer Remote Control Transmitter
Handheld IR/RF remote controls benefit from the PIC16F676T-I/ST's low cost and ultra-low sleep current, enabling multi-year battery life from a single coin cell. The 8-bit core handles button scanning, code transmission, and basic pairing logic, while the 10-bit ADC reads battery voltage for low-battery warning. ICSP allows manufacturers to lock firmware via code protection after final assembly. The TSSOP-14 package reduces PCB area versus SOIC-16 alternatives, fitting easily within a slim remote housing. Microchip's application notes for IR modulation (e.g., RC-5, SIRC) provide ready firmware frameworks for fast time-to-market.

Hobbyist and Educational Development Board
The PIC16F676T-I/ST serves as the heart of low-cost PIC training boards and DIY electronics kits, where its 14-pin TSSOP package is compatible with breadboard adapters and PICkit programmer headers. Students learn 8-bit RISC architecture, assembly language, and embedded C programming through hands-on projects including LED chasers, timers, and serial communication. Microchip's free MPLAB X IDE, XC8 compiler, and PICkit 3/4 programmer provide a complete learning ecosystem. The 1.75 KB Flash holds complete lab exercises, and 128-byte EEPROM retains user settings across power cycles. Affordable pricing enables one-chip-per-student learning kits at scale.

Home Appliance Control Board
The PIC16F676T-I/ST integrates small home appliances such as coffee makers, slow cookers, and fan controllers by replacing electromechanical timers with precise digital control. The 10-bit ADC reads temperature from NTC thermistors, the comparator triggers safety shutoffs, and PWM outputs drive TRIAC gates or MOSFET switches for variable-speed motor control. Industrial temperature grade (-40 to +85 °C) handles the heat near heating elements. The TSSOP-14 footprint is compatible with standard 14-pin through-hole carriers, simplifying retrofit of legacy timer boards. Microchip's code-protection features prevent unauthorized firmware copying by competitors.

ڈیزائن نوٹس
Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of the VDD pin (pin 1) and a 10 µF bulk capacitor at the board supply entry. The PIC16F676T-I/ST operates from 2.0 V to 5.5 V; below 2.0 V the device resets and Flash programming is inhibited. For battery applications, configure the BOR (Brown-Out Reset) via configuration bits to ensure predictable reset behavior at low battery voltage.
The MCLR pin (pin 4) must never be left floating - tie it to VDD through a 10 kΩ pull-up resistor to ensure proper reset behavior. If MCLR is unused as a reset input, configure it as a digital input by setting the MCLRE configuration bit to OFF. When using ICSP programming, leave the MCLR/VPP pin accessible for the programmer header. Floating MCLR causes intermittent resets and unreliable start-up.
TSSOP-14 land pattern requires IPC-7351 nominal pads with 0.40 mm pitch. Place the crystal or external clock source within 5 mm of pins 2-3 (OSC1/OSC2) and route traces over a continuous ground plane to minimize EMI. Keep digital I/O traces away from analog ADC inputs (RA0-RA2, RA5/RC0-RC3) by at least 3 mm or shield with a ground pour to reduce digital switching noise coupling into ADC readings.
