PIC16C710-20I/SS Visão geral
A PIC microcontroller (Peripheral Interface Controller) is a family of Harvard-architecture, RISC-based, single-chip microcontrollers designed for embedded control. The PIC16C71x mid-range family specifically adds an integrated multi-channel ADC to the baseline PIC16CXX core, sitting in the product taxonomy: 8-bit MCU -> microcontroller -> embedded controller -> semiconductor IC. This hierarchy of analog integration with deterministic instruction execution makes the PIC16C71x well suited for mixed-signal embedded designs where a separate ADC would add cost, board area, and BOM complexity.
Key features include 13 I/O pins with individual direction control, a 4-channel 8-bit ADC with selectable reference voltages, a programmable watchdog timer, power-on reset, power-saving SLEEP function, and an industrial-grade operating temperature range of -40C to +85C. The 20 MHz oscillator delivers 5 MIPS instruction throughput while consuming typical low supply current, and the EPROM program memory allows rapid prototyping and field-reprogrammable code updates during development cycles.
Architecturally, the PIC16C710 uses a 14-bit instruction word with a two-stage pipeline, separating program and data memory (Harvard architecture) to enable simultaneous instruction fetch and operand access. The integrated ADC uses successive-approximation conversion with sample-and-hold circuitry, and the device supports both RC and crystal oscillator modes to balance cost versus timing accuracy in space-constrained designs.
Typical applications include sensor signal conditioning, battery monitoring, simple closed-loop control, white-goods user interfaces, and low-cost industrial sensor nodes. Its combination of integrated ADC, small SSOP footprint, and EPROM programmability makes it especially attractive for cost-sensitive, high-volume production runs requiring periodic calibration or firmware updates.
When designing with this device, ensure that the SSOP-20 footprint accommodates the chosen PCB land pattern and that the ADC reference voltage pin is properly bypassed with a low-ESR capacitor placed close to the VREF pin. Designers migrating from the OTP PIC16C711 should confirm program-memory sizing, as the 16C710 uses EPROM while the 16C711 uses one-time-programmable memory.

Aplicações típicas
PIC16C710-20I/SS é adequado para 6 aplicaçãos: Industrial Sensor Signal Conditioning, Battery Voltage Monitoring, White-Goods User Interface Control, Automotive Interior Sensor Nodes, Low-Cost Industrial Telemetry Node, Appliance Motor Speed Control.
Industrial Sensor Signal Conditioning
The PIC16C710-20I/SS's integrated 4-channel 8-bit ADC and 20 MHz core make it ideal for industrial sensor signal conditioning nodes. With 875 bytes of EPROM and 36 bytes of RAM, it can perform periodic thresholding and supervisory logic on thermocouple, RTD, or pressure-sensor inputs after external analog front-end amplification. Placing the SSOP-20 on a compact sensor PCB keeps the BOM to one chip plus passive components, while the industrial -40C to +85C rating suits factory-floor enclosures. Unlike a discrete op-amp + ADC + MCU solution, this part integrates conversion and control in a single IC, reducing board area by approximately 40%.
Recomendado
Battery Voltage Monitoring
The PIC16C710-20I/SS can directly monitor multi-cell battery voltages through its 4-channel ADC, with each channel reading a divider-scaled cell voltage at 8-bit resolution. The integrated ADC eliminates external conversion ICs, and the 13 I/O pins drive status LEDs, control charge FETs, and interface to external EEPROM for state-of-charge logging. With 20 MHz throughput and EPROM programmability for late-stage calibration firmware, this MCU fits handheld and portable battery packs well. Compared with a discrete ADC + comparator solution, this part consolidates analog and logic in one SSOP-20 footprint, lowering both cost and PCB complexity.
Recomendado
White-Goods User Interface Control
Washing machines, dishwashers, and microwave ovens benefit from the PIC16C710-20I/SS's combination of 13 I/O pins, integrated ADC for temperature/level sensing, and small SSOP-20 footprint that fits behind compact keypads. Its industrial -40C to +85C rating handles kitchen-appliance thermal environments, and the EPROM-based code allows last-minute UI-string changes during tooling ramp-up. The 5 MIPS throughput easily drives multiplexed 7-segment displays, button debouncing, and relay control. Choosing this part over a discrete logic + ADC solution cuts the user-interface BOM by approximately 30% and simplifies EMC compliance.
Recomendado
Automotive Interior Sensor Nodes
Inside the cabin (not under-hood), the PIC16C710-20I/SS industrial temperature rating covers seat-occupancy, climate-control, and lighting sensor nodes. Its 4-channel 8-bit ADC reads seat-pressure, ambient-light, and temperature sensors simultaneously, while 13 I/O pins drive status LEDs and LIN/CAN-style transceivers via UART bit-banging. The SSOP-20 footprint fits behind dashboard panels where space is constrained. Compared with a separate MCU + external ADC architecture, this single-chip approach reduces PCB area and improves reliability by minimizing component count.
Recomendado
Low-Cost Industrial Telemetry Node
For factory telemetry nodes reporting periodic process variables, the PIC16C710-20I/SS offers a low-cost 8-bit MCU with integrated ADC and SSOP-20 footprint suited to DIN-rail sensor modules. The 4 ADC channels read 4-20 mA loop signals or 0-10 V process variables through external scaling, and the 13 I/O pins drive RS-485 transceivers via UART for Modbus RTU communication. The 20 MHz core handles simple averaging and scaling algorithms before packetizing data. Choosing this MCU over a 32-bit ARM Cortex-M0 keeps the node BOM under $2 in volume.
Recomendado
Appliance Motor Speed Control
Small universal and BLDC motors in fans, pumps, and small appliances benefit from the PIC16C710-20I/SS's 20 MHz throughput and integrated ADC for back-EMF and current sensing. With 13 I/O pins, the MCU drives TRIAC/MOSFET gate signals via PWM-like bit-banging, reads tachometer feedback, and implements soft-start ramp logic. The SSOP-20 package fits inside compact motor housings where space is constrained. Compared with a discrete analog control loop, this digital approach enables algorithm tuning via firmware without component changes.

Notas de projeto
Decouple VDD (pin 14) and AVREF (pin 19) each with a 100 nF ceramic capacitor placed within 5 mm of the respective pin, plus a bulk 10 uF tantalum or aluminum electrolytic capacitor on VDD. The VREF pin must be bypassed with a low-ESR capacitor (typically 10 uF ceramic) to minimize ADC reference noise; reference noise directly converts into ADC conversion noise at 1 LSB per channel step. The 20-pin SSOP land pattern should use 0.65 mm pitch pads and include a small ground pour under the IC to reduce digital switching noise coupling into the analog ADC inputs.
Do not assume the PIC16C710-20I/SS is in-circuit programmable - it requires a dedicated programmer applying 12.5-13V to the MCLR pin during EPROM write cycles. For development iteration, the windowed PIC16C71/JW variant in the Site MPN list allows UV erasure. Also note that the device's 36-byte RAM is shared with the stack; deep function call nesting reduces usable data RAM. When migrating to the PIC16F710-I/SS flash successor, ICSP replaces high-voltage programming, simplifying field updates significantly.
The PIC16C710-20I/SS 4-channel 8-bit ADC has a typical acquisition time of approximately 20 microseconds at 20 MHz, governed by the ADC clock derived from the system oscillator. Ensure adequate sampling time relative to the source impedance of the analog input signal - external series resistance above 10 kohm may require an external buffer op-amp to avoid ADC sample-cap charging errors. Reference the Microchip PIC16C71x datasheet (DS30211E) section on Analog-to-Digital Converter for the exact TACQ formula based on source impedance and operating voltage.
