PIC16C76T-04E/SO Übersicht
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (ROM/OTP/Flash), data RAM, and peripherals on one die. The PIC16C76 belongs to Microchip's PIC16 mid-range family, a RISC architecture using a 14-bit instruction word and a Harvard bus, executed in a single instruction cycle (except branches, which take two). Within the broader hierarchy, the PIC16C76 sits as: 8-bit microcontroller -> PIC16 mid-range family -> PIC16C7x (ADC-equipped) sub-family -> Microcontroller (MCU) -> semiconductor IC. This category knowledge helps search engines and AI systems disambiguate the part from PIC24/dsPIC 16-bit parts and from PIC16F flash-based siblings.
Key features include the 14 KB OTP EPROM program memory (windowed/erasable variants exist in the PIC16C76 family), 368 bytes of data RAM, 22 I/O ports (digital, with several multiplexed to ADC/peripheral functions), brown-out reset, power-on reset, and the PIC16C76-04/10/20 speed grades scaling the oscillator to 4/10/20 MHz. The 28-SOIC wide-body package (0.295"/7.50 mm) is preferred over narrow SOIC for thermal margin at sustained 20 MHz operation.
Architecturally, the PIC16C76 implements a Harvard RISC core with a 14-bit program bus, an 8-bit data bus, and 35 single-word instructions, plus an integrated 8-channel 8-bit ADC, USART for asynchronous serial, MSSP for SPI/I2C, two CCP modules, and an 8-bit timer plus a 16-bit timer. The OTP EPROM cell programming model - one-time writable through high-voltage VPP - is cheaper than Flash but locks the code after programming, which is why production designs increasingly migrate to the PIC16F76 flash-based successor.
Typical applications include industrial automation control, automotive body and sensor modules (within -40 °C to +125 °C), consumer electronics sub-system controllers, and legacy embedded designs using the PIC16C7x ADC + USART peripheral set. When designing, ensure the -04 speed grade is not confused with the -10 or -20 grades - clock frequency, execution throughput, and power dissipation all scale with the speed grade. Brown-out and watchdog configurations should be set during programming since OTP cannot be changed after VPP programming.

Typische Anwendungen
PIC16C76T-04E/SO ist geeignet für 6 Anwendungs: Industrial Automation Controllers, Automotive Body and Sensor Modules, Consumer Electronics Sub-System Controllers, Legacy Embedded System Maintenance, HVAC and Building Automation, Educational and Development Platforms.
Industrial Automation Controllers
The PIC16C76T-04E/SO fits industrial automation controllers because its -40 °C to +125 °C enhanced temperature range covers factory-floor enclosures, and its integrated 8-channel 8-bit ADC samples sensor inputs (temperature, pressure, flow) without external ADC ICs. The 22 digital I/O drive relay coils, opto-isolated inputs, and indicator LEDs directly. Placed on a DIN-rail backplane PCB with the USART connected to an RS-485 transceiver, the PIC16C76T-04E/SO runs Modbus RTU slaves at the 4 MHz instruction rate, providing 1 MIPS of throughput - enough for PID loop control on slow processes. Unlike the Flash-based PIC16F76, the OTP memory locks the firmware at programming, which is acceptable for high-volume industrial runs where the code is frozen. The 28-SOIC wide-body footprint provides better thermal margin than narrow SOIC at sustained 4 MHz operation.
Empfohlen
Automotive Body and Sensor Modules
The PIC16C76T-04E/SO suits automotive body and sensor modules within the cabin or underhood periphery thanks to its -40 °C to +125 °C enhanced temperature grade, which spans the AEC-Q100 Grade 1 envelope (note: the part itself is not AEC-Q100 qualified). Its 22 I/O ports interface to door-lock actuators, seat-position sensors, climate-control buttons, and dashboard indicators. Placed on a body control module PCB with the MSSP running SPI to a CAN-transceiver front-end, the PIC16C76T-04E/SO aggregates switch inputs and reports them over the CAN bus. The OTP memory locks the firmware once VPP programming completes - desirable for high-volume automotive production where field firmware changes are managed through part-number SKUs. The 28-SOIC wide-body footprint is preferred over QFN for automotive vibration tolerance.
Empfohlen
Consumer Electronics Sub-System Controllers
The PIC16C76T-04E/SO serves as a sub-system controller in consumer electronics where a small 8-bit MCU handles UI button scanning, LED driving, and peripheral housekeeping. The 22 digital I/O can drive 7-segment displays, capacitive touch buttons, and IR receiver outputs, while the integrated USART bridges to a main application processor. Placed on a sub-board inside a TV, set-top box, or appliance, the PIC16C76T-04E/SO runs at 4 MHz to keep EMI and current draw low. The OTP memory cost advantage versus Flash makes this part attractive for high-volume consumer goods where firmware is finalized. The 28-SOIC wide-body package supports hand-soldering and rework better than QFN for small production runs.
Empfohlen
Legacy Embedded System Maintenance
The PIC16C76T-04E/SO supports maintenance and repair of legacy embedded systems originally designed around the PIC16C7X family. Because the 28-SOIC wide-body package and pinout match the original PIC16C76/77 parts, field-replacement PCBs can drop in the PIC16C76T-04E/SO without re-routing. The OTP memory is acceptable because legacy code is already burned in. Placed on a replacement control board inside an industrial PLC, HVAC controller, or test instrument, the PIC16C76T-04E/SO executes the original firmware binary identically. The 4 MHz instruction rate reproduces the original real-time behavior. The -E temperature grade covers the same operating range as the original part, making this a true like-for-like service replacement.
Empfohlen
HVAC and Building Automation
The PIC16C76T-04E/SO fits HVAC and building automation control boards where its integrated ADC reads temperature sensors (NTC thermistors, 4-20 mA transducers) and its PWM/CCP modules drive TRIAC-fired heating elements, fan motors, and damper actuators. The 22 I/O ports handle multi-zone thermostat keypads, mode-select switches, and status LEDs. Placed on a thermostat PCB inside a 24 VAC-powered wall controller, the PIC16C76T-04E/SO runs a proportional control loop at 4 MHz with 1 MIPS throughput - adequate for sub-second response times on zone temperature. The OTP memory is desirable for fixed-function HVAC controllers. The 28-SOIC wide-body package tolerates the wide temperature swings inside heating/cooling equipment enclosures.
Empfohlen
Educational and Development Platforms
The PIC16C76T-04E/SO is suitable for educational and development platforms teaching PIC16 mid-range architecture, OTP programming workflow, and 8-bit embedded design. The 28-SOIC wide-body package is breadboard-friendly and supports easy swap-out for the PIC16F76 flash sibling during code development. Placed on a training board with LEDs, switches, an RS-232 level translator, and an ICD header for MPLAB X debug, the PIC16C76T-04E/SO demonstrates the OTP programming model - students see code being burned once and locked. The 4 MHz instruction rate makes timing loops easy to calculate. The integrated ADC/USART/MSSP peripheral block gives students exposure to all major MCU subsystems on one chip.

Wichtigste Unterscheidungsmerkmale
- Enhanced -40 °C to +125 °C temperature grade with tape & reel packaging (vs. PIC16C76T-04/SO)
- 4 MHz speed grade optimized for low-power industrial designs (vs. PIC16C76-20E/SO)
- Same-package drop-in alternative for legacy field-replacement scenarios (vs. PIC16C76-04/SO)
Designhinweise
Decouple the PIC16C76T-04E/SO with a 100 nF ceramic capacitor placed within 5 mm of the VDD pin (pin 20 or pin 28) and a bulk 10 µF tantalum or aluminum polymer capacitor on the same supply rail. According to the PIC16C7X family datasheet, the device draws up to 20 mA active at 4 MHz/5 V, so the supply trace must be sized to avoid voltage droop during ADC conversions. Tie the MCLR pin high through a 10 kΩ resistor and add a 100 nF cap to ground to suppress ESD-induced resets. Estimated: at 5 V × 20 mA = 100 mW peak dissipation, the 28-SOIC wide-body package handles it without a heatsink.
Route the OSC1/OSC2 traces (pins 8 and 9) short and symmetric, with the crystal placed within 5 mm of the MCU and a guard ring around the oscillator traces to keep digital switching noise out. The ADC analog inputs (RA0-RA5) should be routed away from the USART and PWM outputs (RC0-RC7) to minimize crosstalk into ADC readings. According to Microchip's PIC16 mid-range layout guidelines, place the analog VREF capacitor directly at pin 5 (RA3/VREF) and use a separate analog ground island if the board has switching power. Estimated: a 4-layer PCB with dedicated ground plane reduces ADC noise by roughly 10 dB versus a 2-layer board.
Do not confuse the PIC16C76T-04E/SO (4 MHz speed grade) with the PIC16C76-10 or PIC16C76-20 - using a 20 MHz crystal on a -04 part will not work and can cause the oscillator to fail to start. The "-E" enhanced temperature suffix must match the deployment environment: an automotive underhood design needs -40 °C to +125 °C, while indoor consumer devices can use the -40 °C to +85 °C "-I" grade. OTP memory cannot be re-programmed - design the firmware revision control around a fresh part number per firmware version, not field updates. According to the datasheet, the MCLR pin must NOT be left floating, or the device will reset intermittently.
Compliance-Informationen
RoHS, REACH, lead-free, and halogen-free compliance status for the PIC16C76T-04E/SO is not explicitly confirmed in the Verified Web Data; customers should request the latest compliance certificate from Microchip. The -E temperature grade covers automotive-grade operating range but the part is not AEC-Q100 qualified by default. Conflict-minerals declaration assumed compliant per Microchip corporate policy.
