PIC16F76T-E/SO 概要
What is a PIC microcontroller? A PIC (Peripheral Interface Controller) is an 8-bit RISC microcontroller family originally developed by General Instrument and now produced by Microchip Technology. The PIC architecture uses a Harvard design with separate program and data buses, a small instruction set (35 single-word instructions for the PIC16F76), and integrated peripherals like ADC, timers, and PWM. PIC microcontrollers belong to the broader hierarchy: microcontroller -> embedded MCU -> semiconductor IC, and remain a foundation of embedded design education, hobbyist platforms, and industrial control.
Key features of the PIC16F76 include a 20 MHz maximum operating frequency (5V), 22 digital I/O pins, two 8-bit timers plus one 16-bit timer, a 5-channel 8-bit Analog-to-Digital (A/D) converter, a USART for serial communication, a Synchronous Serial Port (SSP) supporting SPI and I2C, a Capture/Compare/PWM (CCP) module, and a watchdog timer with on-chip RC oscillator. The 28-pin SOIC package supports through-hole-style PCB layouts while remaining suitable for surface-mount assembly.
The architecture is upward-compatible with the PIC16C5X, PIC12CXXX, and PIC16C7X device families, simplifying code portability across Microchip 8-bit portfolios. The 35-instruction RISC core provides deterministic execution time, useful for real-time control loops in motor drives and sensor interfacing.
Typical applications include industrial automation controllers, automotive body electronics, sensor signal conditioning, low-end motor control, smart sensor nodes, consumer appliance control boards, and battery-powered measurement instruments. The wide temperature range and robust peripheral set make the PIC16F76 particularly suited to harsh-environment embedded designs.
When designing with this device, ensure the ICSP programming header is accessible for in-circuit firmware updates. Decouple VDD and VSS with 100 nF ceramic capacitors placed within 5 mm of each supply pin. For analog accuracy, route the AVDD/AVSS supply pair separately from noisy digital logic.

おすすめ
Automotive Body Electronics
The PIC16F76T-E/SO is well-suited for non-safety automotive body electronics such as HVAC damper control, seat position memory, instrument cluster sub-controllers, and lighting modules. The Extended -40C to +125C grade tolerates cabin and under-hood thermal stress. The 14KB flash supports mid-complexity firmware for body control modules with multi-channel ADC inputs reading temperature, position sensors, and switch arrays. For projects requiring AEC-Q100 qualification, engineers should evaluate PIC16F876A or PIC16F1936 families instead, but for non-safety applications the PIC16F76T-E/SO provides cost-effective thermal margin.

設計ノート
Decouple each Vdd/Vss pair with a 100 nF ceramic capacitor placed within 5 mm of the IC pins; for noise-sensitive analog designs add a 10 uF bulk capacitor on the main Vdd rail. Route AVDD/AVSS (where applicable) separately from the noisy digital Vdd/Vss pair. The PIC16F76 supports 2.0V to 5.5V operation, but the 20MHz CPU clock requires Vdd >= 4.5V per Microchip datasheet 30277C, so verify supply headroom at full speed.
Reserve a 5-pin header for In-Circuit Serial Programming (ICSP) accessible from the board edge, with PGC on RB6, PGD on RB7, MCLR held at programming voltage (typically 13V), Vdd, and Vss. Without ICSP access, firmware field updates become costly. Place the MCLR pull-up (typically 10 kohm) close to the IC, and add a Schottky diode from MCLR to Vdd for ESD protection.
The 8-bit ADC achieves best linearity when the source impedance is below 2.5 kohm; add a low-pass RC filter (1 kohm + 100 nF) for higher-impedance sensors. Use AVss as the ADC reference ground and route it as a star-connection from a single point to avoid digital switching noise coupling into conversions. For 5V designs, expect ADC full-scale near 5V with reference voltage tied to Vdd.
Do not exceed 5.5V on any pin including MCLR during normal operation. The PIC16F76 CCP module supports PWM with up to 10-bit resolution but only one CCP is fully enhanced on this family - verify timer/PWM mapping in the datasheet before designing multi-channel PWM. When migrating PIC16F76 firmware to PIC16F73, watch for the 50% flash reduction and adjust code accordingly. Configuration bits (FOSC, WDTE, PWRTE, BOREN) must be set correctly or the MCU may fail to start.
The 28-SOIC package has a typical theta_JA of approximately 60-80 C/W depending on PCB copper pour. At maximum ambient of 125C for E-grade parts, the junction temperature may approach the 150C absolute maximum under heavy I/O switching loads. For high-I/O designs (>20 mA per pin), calculate worst-case power dissipation and provide thermal vias or copper pour to keep Tj below 125C. Estimated: Tj rise = P_diss * theta_JA; at 4.0 mA per pin across 22 outputs and 0.4V Voh drop, dissipation is approximately 35 mW with negligible thermal impact.
