PIC16C710-04/SS Overview
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and peripherals around an 8-bit data path. Within the embedded-systems hierarchy, the PIC16C710 belongs to Microchip's PIC16CXX mid-range family, which sits between baseline PIC10/PIC12 devices and enhanced PIC17/PIC18 devices. This category of MCUs is widely used in automotive, industrial, appliance, and consumer applications where deterministic real-time control, low cost, and simple OTP programming are valued over large memory footprints.
Key features include a 4-channel 8-bit ADC with selectable reference voltages, an 8-bit timer/counter, a watchdog timer, 13 bidirectional I/O pins, and an operating voltage range of 2.5 V to 6.0 V. The device also provides an internal/external oscillator selection, low-power SLEEP mode, and in-circuit serial programming (ICSP) capability. Its 35 single-word instruction set simplifies code development and enables compact, predictable firmware design.
The PIC16C710 is fabricated in CMOS technology with fully static design, ensuring low power consumption and reliable operation across industrial temperature grades. Its RISC architecture delivers deterministic throughput suitable for closed-loop control and sensor acquisition tasks, while the integrated ADC eliminates the need for an external converter, reducing BOM cost.
Typical applications include entry-level A/D conversion in automotive sensors, industrial control systems, white goods and home appliances, consumer electronics, and battery-powered instruments. The combination of OTP memory, 4 MHz operation, and integrated analog channels suits cost-sensitive designs where field programming or small firmware updates are required.
When designing with the PIC16C710-04/SS, ensure that the oscillator configuration (RC, XT, HS, or LP) matches the chosen crystal or resonator, and place decoupling capacitors close to VDD/VSS. The OTP memory allows one-time programming only, so verification on a windowed (-JW) or EPROM-equivalent part is recommended during development before committing to OTP.

- Industrial temperature grade option (vs PIC16C710-04I/SS)
Design Notes
The PIC16C710-04/SS operates from 2.5 V to 6.0 V; place a 0.1 uF decoupling capacitor as close as possible to the VDD pin (pin 14) and a bulk 10 uF electrolytic or tantalum cap at the board-level power entry. According to Microchip's PIC16C71X family datasheet (DS30212D), the device draws roughly 2 mA active at 4 MHz and 1 uA in SLEEP, so a 10 uF bulk cap adequately suppresses voltage transients during oscillator startup and ADC sampling. In battery-powered designs, route the VDD trace separately from high-current load switches to avoid ADC reference noise coupling into the supply rail.
OTP memory can be programmed only once; verify firmware on a windowed (-JW) or EPROM-erasable prototype before committing to the -04/SS OTP variant for production. According to Microchip's PIC16C71X programming specification, accidental programming locks out further updates, and there is no in-application reprogramming capability on this OTP die. For late-stage firmware revisions or field updates, plan to migrate to the flash-based PIC16F710 or PIC16F628A family, which retains SSOP-20 footprint compatibility but supports ICSP and in-application reprogramming.
Place the decoupling capacitor within 5 mm of the VDD pin and the MCLR pull-up resistor within 5 mm of the MCLR pin (pin 4); keep the MCLR trace short to avoid accidental reset from injected noise. According to Microchip's SSOP-20 land pattern recommendation (IPC-7351 nominal), use 0.4 mm lead pitch and 0.6 mm pad width for the SSOP-20 footprint, with solder mask defined (SMD) pads to improve paste release during reflow. Route the OSC1/OSC2 traces over a continuous ground plane and keep them away from high-current switching nodes to avoid oscillator jitter.
When using the 4-channel 8-bit ADC, add a small RC filter (typically 1 kohm + 100 pF) on each analog input to limit broadband noise injection, especially in industrial environments with motor-driven EMI. According to Microchip's ADC specification in the PIC16C71X family datasheet, the ADC's acquisition time is approximately 20 us at 4 MHz, so source impedances above 10 kohm degrade conversion accuracy. The internal voltage reference (VDD) is suitable for ratiometric measurements; for absolute-accuracy applications, add an external 5 V reference on RA3/AN3 as the ADC reference input.
Compliance Information
The PIC16C710-04/SS is generally not RoHS compliant due to lead-bearing die attach in OTP-based CMOS packaging; verify per-batch with Microchip for modern lead-free variants. Not AEC-Q100 qualified - this is a commercial/industrial grade MCU.
