PIC16F76-E/ML - 8-bit MCU 14KB Flash 20MHz QFN-28 | Microchip
MPN: PIC16F76-E/ML ✓ Hoạt độngPIC16F76-E/ML Tóm tắt
What is a PIC16F76? It is a member of Microchip's mid-range PIC16 family of 8-bit microcontrollers built on RISC architecture with only 35 single-word instructions and 200 ns instruction execution. Within the broader semiconductor hierarchy it sits as: PIC16F76 -> PIC16F7x family -> mid-range PIC16 -> 8-bit MCU -> microcontroller -> embedded IC. The PIC16F7x line is the successor/compatible extension of the PIC16C7x OTP devices and is upward code-compatible with the PIC16C5X and PIC12CXXX baseline families.
Key features include 5 channels of 8-bit Analog-to-Digital conversion, 2 capture/compare/PWM modules, 2 additional timers, a synchronous serial port configurable as either 3-wire SPI or 2-wire I2C bus, and a USART/SCI module. The device operates up to 20 MHz and supports nanoWatt power management with multiple idle/sleep modes. Program memory is 14KB (8K x 14 words) of self-programmable FLASH.
Technical depth: the PIC16F76 uses a Harvard architecture with separate program and data buses, a 14-bit instruction word, and an 8-bit data path. The 28-VQFN exposed pad package provides a low thermal resistance path to the PCB copper pour and a small 6x6 mm footprint suitable for space-constrained designs.
Typical applications include industrial control loops, sensor signal conditioning with on-chip ADC, low-cost motor control via PWM, and consumer appliance interfaces. When designing with this device, pay attention to the oscillator configuration bits and ensure the in-circuit serial programming (ICSP) pins are accessible for field firmware updates.

Ứng dụng tiêu biểu
PIC16F76-E/ML phù hợp cho 7 Áp dụngs: Industrial Control Loop, Automotive Under-Hood Sensor Module, Consumer Appliance Interface, Low-Cost PWM Motor Driver Controller, Sensor Signal Conditioning Hub, Electronic Point-of-Sale Terminal, Hobbyist and Education Development Platform.
Industrial Control Loop
The PIC16F76-E/ML is well suited for industrial closed-loop control applications where its extended -40C to +125C operating range handles harsh factory environments without derating. The 5-channel 8-bit ADC provides sufficient resolution for sensor signal acquisition (temperature, pressure, flow) in PLC input modules, while the two CCP/PWM modules drive proportional valves and motor speed controllers. The 14KB Flash accommodates state-machine logic plus Modbus RTU stacks over the on-chip USART. Designers should allocate pin PB0/PB1 to the ICSP interface for in-field firmware updates common in industrial installations.
Được đề xuất
Automotive Under-Hood Sensor Module
The PIC16F76-E/ML's extended -40C to +125C temperature grade and robust 28-pin QFN EP thermal path make it appropriate for automotive under-hood sensor modules monitoring battery current, coolant temperature, or oil pressure. The 5-channel 8-bit ADC multiplexes multiple analog sensors with sample rates up to approximately 50 ksps, while the USART interfaces to a vehicle ECU. The 14KB Flash supports sensor linearization tables and diagnostic routines. Note that AEC-Q100 qualification is not implied by the -E suffix; for AEC-Q100 designs a qualified PIC16 alternative should be selected.
Được đề xuất
Consumer Appliance Interface
White goods and consumer appliances benefit from the PIC16F76-E/ML's small 28-QFN EP footprint, low nanoWatt power-management modes, and flexible serial peripherals driving keypads, displays, and triac-based AC loads. The 14KB Flash stores UI state machines, wash-cycle profiles, and fault logs; the two CCP/PWM modules generate zero-cross switching and motor soft-start ramps. The 368-byte RAM is sufficient for runtime variables and a small RTOS kernel. The 20 MHz clock supports responsive HMI updates without perceptible lag.
Được đề xuất
Low-Cost PWM Motor Driver Controller
The PIC16F76-E/ML's two CCP/PWM modules deliver complementary PWM outputs at up to 20 MHz clock rates, making it ideal as a low-cost BLDC or brushed-DC motor controller. The PWM resolution reaches approximately 10 bits at moderate switching frequencies, and the dead-band control via firmware prevents shoot-through in half-bridge drivers. The 5-channel ADC samples back-EMF for sensorless commutation, while the USART exposes a debug telemetry stream. The 28-QFN EP package provides a low thermal-resistance path for the MCU under continuous switching load.
Được đề xuất
Sensor Signal Conditioning Hub
The PIC16F76-E/ML's 5-channel 8-bit ADC multiplexes multiple analog sensors (temperature, light, humidity) with on-chip computation in firmware, transmitting processed data over SPI or I2C to a host processor. The 14KB Flash accommodates calibration constants and look-up tables for sensor linearization, while the 368-byte RAM supports a small sliding-window filter. The nanoWatt sleep modes reduce quiescent current to microampere levels for battery-powered IoT edge nodes; the extended -40C to +125C range suits outdoor enclosures.
Được đề xuất
Electronic Point-of-Sale Terminal
The PIC16F76-E/ML fits compact POS peripherals such as barcode-scanner handles, receipt-printer controllers, and PIN-pad keypads, where its 22 I/O lines interface directly to switches, LEDs, and a serial display. The USART/SCI module communicates to a host terminal, while the SSP module configured as I2C drives an EEPROM for transaction logging. The 14KB Flash stores keypad scan maps and protocol handlers, and the -40C to +125C range accommodates outdoor market-stall environments.
Được đề xuất
Hobbyist and Education Development Platform
The PIC16F76-E/ML is an excellent teaching platform for embedded-systems courses because of Microchip's free MPLAB X IDE, XC8 compiler, and PicKit programmer support. The 14KB Flash exercises mid-size C programs, the USART/SCI module teaches serial-communication protocols, and the ADC introduces real-world analog interfacing. The 28-QFN EP package is breadboard-adapting friendly via breakout boards, and the -E temperature grade tolerates student-handling thermal excursions.

Ghi chú thiết kế
The PIC16F76-E/ML operates from 2.0V to 5.5V. Add a 100 nF decoupling capacitor close to the VDD pin (pin 26) and a 10 uF bulk capacitor near the supply input. For nanoWatt sleep-mode operation, ensure all unused I/O pins are configured as outputs low or inputs with the internal weak pull-ups disabled to minimize quiescent current. The MCLR pin should have a 10 kohm pull-up to VDD with a 100 nF cap to ground if not driven by an external supervisor.
The 28-pin QFN EP package dissipates heat through the exposed pad on the underside. Recommended PCB layout: provide a copper pour of at least 25 mm^2 on the top and inner layers, stitched with thermal vias (0.3 mm pitch, 9+ vias) directly under the EP. Without the EP soldered to a thermal pour, junction-to-ambient thermal resistance can exceed 100 C/W, derating the -40C to +125C operating range under sustained loads.
Do not leave the OSC1/OSC2 pins floating if an external oscillator is selected - this can cause erratic clock behavior or excess current. The configuration word must match the oscillator selection (HS, XT, LP, RC) and the watchdog timer and brown-out reset bits must be set explicitly; they default disabled but are easy to forget in production firmware. Finally, when using ICSP, isolate the ICSPCLK/ICSPDAT lines from high-impedance analog signals to prevent programming failures.
Thông tin tuân thủ
RoHS and lead-free compliance per Microchip product page. The -E temperature grade is NOT equivalent to AEC-Q100 automotive qualification; choose an AEC-Q100 qualified PIC16 variant for automotive designs.
