PIC16C710T-04E/SO Descripción general
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, working RAM, and peripheral set on one die. The PIC16C architecture is a Harvard-type RISC core with 35 single-word instructions and is upwards compatible with PIC16C5X and PIC12CXXX devices. Positioned in the broader taxonomy, the PIC16C710 belongs to the mid-range PIC family, sitting between baseline (PIC10/12/16C5X) and enhanced mid-range (PIC16F) MCUs, and is a member of the power management and embedded control semiconductor category.
Key features include four channels of 8-bit Analog-to-Digital conversion with on-chip sample-and-hold, a programmable code-protection bit, an internal RC oscillator option, a Watchdog Timer with its own on-chip RC oscillator, and a power-saving SLEEP mode. The brown-out-reset is not present on this OTP silicon, so designers needing BOR should migrate to the PIC16F710 flash sibling. The 18-SOIC wide-body footprint keeps the part compatible with hand-soldered prototypes as well as high-volume SMT lines.
Architecturally, the device uses a 14-bit instruction word with separate program and data buses (Harvard), giving deterministic single-cycle execution except for branch instructions that take two cycles. The 4-channel 8-bit ADC can digitize analog sensor inputs directly, removing the need for an external ADC in simple data-acquisition applications.
Typical applications include battery chargers, consumer white goods, HVAC controls, simple sensor interfaces, and low-cost motor-control signal conditioning. With 4 MIPS at 5 V and only 13 I/O, it is well matched to space-constrained, low-pin-count embedded designs.
When designing with the PIC16C710T-04E/SO, ensure that the MCLR reset network (typically 10 kohm pull-up to VDD) is present and that decoupling uses a 0.1 uF ceramic capacitor placed within 5 mm of the VDD pin. Note that this OTP variant can be programmed only once; for prototypes requiring firmware iteration, the PIC16F710 in the same 18-SOIC footprint with flash memory is recommended.
This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes not found in the manufacturer datasheet alone, giving procurement and firmware engineers a single reference for sourcing and substituting the PIC16C710T-04E/SO.

Aplicaciones típicas
PIC16C710T-04E/SO es adecuado para 7 aplicacións: Battery Charger Controller, HVAC Thermostat, Simple Sensor Interface Module, Consumer White-Goods Control Board, Low-Cost Motor Control Signal Conditioning, Automotive Interior Lamp Timer, Educational Microcontroller Trainer.
Battery Charger Controller
The PIC16C710T-04E/SO fits low-cost NiCd/NiMH charger designs because its 4-channel 8-bit ADC measures battery voltage, charge current and temperature while two timers drive PWM charge and discharge gating. At 4 MHz it executes the charge-state machine in 200 ns per step, easily handling CC/CV loops at 1 kHz without software overhead. The 13 I/O are sufficient to drive status LEDs, a relay/MOSFET gate, and a 7-segment charge-level display. Although OTP, the firmware is fixed once validated, which is acceptable in high-volume consumables.
Recomendado
HVAC Thermostat
The PIC16C710T-04E/SO suits residential HVAC thermostats because it digitizes the thermistor bridge via its 8-bit ADC, drives a triac opto-coupler for compressor control, and reads setpoint buttons on RB0-INT interrupts. The 5 MIPS throughput runs a PI temperature loop at 10 Hz with margin for LCD multiplexing. Its -40 to +125 C extended-temperature grade lets the MCU sit directly on the wall plate near the heat-generating triac, eliminating the need for a remote sensor MCU.
Recomendado
Simple Sensor Interface Module
Industrial 4-20 mA sensor transmitters benefit from the PIC16C710T-04E/SO's 8-bit ADC for digitizing bridge or thermistor front ends, while its UART-less design keeps bill of materials low. The Watchdog Timer with its own RC oscillator survives brown-outs on long cable runs, and the SLEEP mode draws microamps for battery-powered field nodes. 13 I/O are enough for the loop-powered output DAC (driven by PWM+filter), two alarm LEDs and a calibration pushbutton.
Recomendado
Consumer White-Goods Control Board
Washing machines, dishwashers and microwave ovens use the PIC16C710T-04E/SO for sequencing motors, valves and relays while its ADC monitors water level or humidity sensors. With 5 MIPS the device multiplexes a 7-segment display and keypad without flicker, and the Timer1 capture/compare generates zero-crossing triac triggers for heater PWM. The OTP memory locks in the appliance firmware to prevent post-sale firmware tampering and to lock out counterfeit clones.
Recomendado
Low-Cost Motor Control Signal Conditioning
Small brushless-DC or stepper driver boards pair the PIC16C710T-04E/SO with a power-stage gate driver: the MCU reads back-EMF via the 8-bit ADC, generates commutated PWM on Timer0/1, and provides start-up torque via a look-up table. The 4 MHz clock is sufficient for 2 kHz commutation loops used in fan and pump motors. The 18-SOIC package fits within a 0.5 square-inch footprint, leaving room for the half-bridge MOSFETs and current-sense shunt.
Recomendado
Automotive Interior Lamp Timer
The PIC16C710T-04E/SO drives interior courtesy lamps with fade-out timing in automotive body controllers. The extended -40 to +125 C grade tolerates cabin temperatures, while the Watchdog Timer recovers from load-dump-induced resets. Although AEC-Q100 is not qualified on the C part, the flash PIC16F710-Q1 is used for the same function in AEC designs. Only 13 I/O are needed to drive N-channel MOSFET high-side switches and read the door-switch inputs on the INT pin.
Recomendado
Educational Microcontroller Trainer
Universities and vocational labs choose the PIC16C710T-04E/SO for embedded-systems teaching because the 35-instruction PIC16C set is small enough to learn in a semester, the 18-SOIC package is hand-solderable, and the 8-bit ADC gives students hands-on analog experience. The OTP memory forces a structured development workflow: code is prototyped on a flash PIC16F710, validated, then committed to the PIC16C710T-04E/SO for production-grade demonstration boards.

Notas de diseño
PIC16C710 VDD range is 4.0 V to 6.0 V; operation below 4.0 V is not guaranteed per the Microchip datasheet. Decouple VDD with a 0.1 uF ceramic capacitor placed within 5 mm of the pin and parallel it with a 10 uF tantalum or ceramic bulk capacitor if the supply traces exceed 25 mm. For noise-sensitive analog reads, place an additional 0.01 uF capacitor adjacent to the AVdd/VREF pin (shared with RA3 on this device).
This is an OTP part - once programmed, the memory cannot be erased. Develop and validate firmware on a flash-based PIC16F710-I/SO on the same 18-SOIC footprint, then port the validated .hex file to PIC16C710T-04E/SO for production. Also remember that the PIC16C710 has NO brown-out reset; if your system needs VDD under-voltage protection, add an external voltage supervisor such as MCP100/MCP102 driving the MCLR pin.
The 18-SOIC wide-body footprint accepts both 0.300 inch (7.50 mm) PIC16C71x SOIC and 0.295 inch PIC16F84A SOIC variants; verify your land pattern matches JEDEC MS-013. Keep the MCLR pull-up resistor within 5 mm of pin 1 to limit the rise-time during power-up, and route OSC1/OSC2 traces short and guarded to avoid injecting noise into the analog ADC channels on RA0-RA3.
When using the 8-bit ADC on RA0-RA3, drive the analog source through a low-impedance buffer (op-amp follower such as MCP6001) to avoid ADC sample-charge distortion. Acquisition time per the datasheet is approximately 19.7 us at 4 MHz; the source impedance should stay below 10 kohm to meet this. RA4 is an open-drain output on this device, so an external pull-up is required when used as a digital output.
