PIC16LF76T-I/SOG - 8-bit PIC MCU, 14KB Flash, 28-SOIC | Microchip
MPN: PIC16LF76T-I/SOG ✓ Hoạt độngPIC16LF76T-I/SOG Tóm tắt
A PIC (Peripheral Interface Controller) microcontroller is a compact, self-contained computer-on-a-chip that combines a CPU, non-volatile program memory (Flash), volatile data memory (RAM), and a rich set of on-chip peripherals. The PIC16 family sits in Microchip's mid-range architecture tier, providing a balance of deterministic performance, ease of use, and low power consumption that has made PIC microcontrollers a workhorse of industrial and consumer embedded design for over two decades.
Key features of the PIC16LF76T-I/SOG include 14 KB of Flash for program storage, 368 bytes of RAM, 256 bytes of EEPROM data memory, 22 digital I/O lines multiplexed with peripheral functions, a 10-bit analog-to-digital converter with up to 8 input channels, two 8-bit timers plus one 16-bit timer, a 10-bit PWM module, an enhanced USART, a Master Synchronous Serial Port (MSSP) supporting SPI and I²C, and a watchdog timer for safe operation. The LF (low-power) silicon variant operates across a wide VDD range, supporting battery-backed and energy-constrained designs.
Technically, the PIC16F7x architecture employs a 14-bit instruction word and a Harvard bus structure that lets the CPU fetch instructions and data in parallel, delivering predictable interrupt latency and efficient C/assembly compilation. The 10-bit ADC achieves conversion rates sufficient for sensor conditioning and instrumentation loops, while the CCP/PWM module is well-suited to motor control, lighting, and power-conversion feedback.
Typical applications for this device include industrial automation and sensor interface nodes, HVAC and building control panels, motor drive and small appliance control, low-power data-acquisition front-ends, and consumer-electronics user-interface controllers. The combination of EEPROM, ample I/O, and standard serial peripherals also suits remote keyless entry, battery chargers, and instrumentation.
When designing with the PIC16LF76T-I/SOG, use the Microchip MPLAB X IDE and MPLAB XC8 compiler for code development, and verify decoupling on VDD/AVDD/VSS with 100 nF and 10 uF capacitors placed close to the pins. The MCLR reset pin requires a proper pull-up configuration; consult the device datasheet for oscillator modes and ICD (in-circuit debug) connections if real-time debugging is required.

Ghi chú thiết kế
Decouple VDD and AVSS with a 100 nF X7R ceramic capacitor placed within 3 mm of the VDD pin and a bulk 10 uF aluminum-polymer or ceramic capacitor on the same supply rail. For the LF (low-power) silicon variant, VDD can operate as low as 2.0V, so verify that the chosen LDO dropout remains within regulation at minimum load current. Estimated: a 100 nF X7R plus 10 uF bulk keeps the supply ripple below 5 mV at the ADC reference pin for typical 10-bit conversions.
Keep the MCLR pull-up resistor within 5 mm of the MCLR/VPP pin (pin 1) and route the ICSP PGC/PGD lines (RB6/RB7) directly to a 6-pin header without stubs. Place the 28-SOIC long-axis parallel to the PCB edge to simplify automated optical inspection, and keep analog traces (RA0-RA5, RC0-RC2) away from the PWM outputs (CCP1/CCP2) to minimize digital-to-analog crosstalk during ADC sampling. Reference Microchip AN585 'PIC16F7x Hardware Design Checklist' for layout guidance.
Do not assume the LF (low-power) variant and standard F (non-LF) variant share the same VDD range - the F76 has narrower voltage tolerance (typically 4.5-5.5V) than the LF76 (down to 2.0V). Always verify the ICSP clock frequency is below 5 MHz for PGC during in-circuit programming; higher rates can cause verify errors on freshly-erased Flash. The AVDD/VSS analog supply pins are not present on this 28-SOIC variant - ADC reference uses VDD as the positive reference, so VDD noise directly couples into ADC readings; add a ferrite bead between digital and analog supply if precision matters.
The enhanced USART on PIC16LF76T-I/SOG supports synchronous and asynchronous modes; for noise-sensitive RS-485 links, configure the baud-rate generator with BRGH=1 to allow higher baud rates with lower BRG error. The MSSP module's I2C pins (RC3/SCL, RC4/SDA) are 5V-tolerant when VDD permits, simplifying connection to legacy 5V sensors. For SPI, ensure the SCK idle state matches the slave device's clock-polarity requirement (CKP bit) to avoid framing errors on the first byte.
