PIC16C710-20E/P - 8-Bit 20MHz OTP MCU 18-PDIP | Microchip
MPN: PIC16C710-20E/P ✗ Akhir HidupPIC16C710-20E/P Ringkasan
An 8-bit microcontroller (MCU) is a single-chip computer containing a CPU, program memory, data RAM, and peripherals such as timers and ADCs. The PIC16C7X family sits within Microchip's mid-range PIC16 architecture, between the baseline PIC10/12/16 series and the high-pin-count PIC17/18 series. The integrated 8-bit ADC allows direct measurement of analog sensors without an external converter, which historically made the PIC16C710 a popular entry-level mixed-signal controller.
Key features of the PIC16C710-20E/P include a 20 MHz maximum operating frequency, 8-bit Timer0 with 8-bit prescaler, brown-out detection circuitry for Brown-out Reset (BOR), 13 individually-direction-controlled I/O pins, and 14-bit instruction word architecture. The 5V operating voltage and 20 MHz clock deliver roughly 5 MIPS of throughput, suitable for simple control loops, sensor reading, and user-interface scanning. The 18-pin PDIP package is pin-compatible with the PIC16C711 and is widely used in legacy through-hole designs.
Internally, the PIC16C710 uses a Harvard architecture with separated program and data buses, an accumulator-based ALU, and a single hardware stack. The 8-bit ADC has 4 input channels multiplexed onto a single sample-and-hold, with the conversion clock derived from the system oscillator. Brown-out Reset protects against code corruption when VDD drops below the BOR threshold.
Typical applications include entry-level automotive body controllers, industrial sensor interfaces, appliance control boards, and consumer devices. The 4-channel ADC is particularly well-suited for monitoring multiple analog sensors - for example temperature, pressure, and humidity - in a single low-cost MCU.
When designing with this device, ensure the system oscillator configuration matches the application's timing needs (RC, XT, HS, or LP modes), and that BOR is enabled for robust power-up behavior. The 18-pin PDIP footprint also makes the part suitable for breadboard prototypes and educational use.

Aplikasi Umum
PIC16C710-20E/P cocok untuk 6 aplikasis: Automotive Body Control Modules, Industrial Sensor Interface Boards, Appliance Control Boards, Consumer Electronics User Interfaces, Battery-Powered Sensor Nodes, Educational and Hobbyist Projects.
Automotive Body Control Modules
The PIC16C710-20E/P's extended -40C to +125C temperature grade and integrated 4-channel 8-bit ADC make it a natural fit for entry-level automotive body controllers where it reads switches, sensors, and analog signals to drive relays and small actuators. Its 20 MHz core delivers 5 MIPS of throughput, sufficient for door/window/lighting logic with software debouncing and basic PWM-style control. The 18-pin PDIP package is straightforward for prototyping and through-hole production lines common in aftermarket automotive electronics. Compared to flash-based alternatives, the OTP program storage ensures firmware cannot be altered in the vehicle - an advantage for tamper resistance.

Industrial Sensor Interface Boards
The PIC16C710-20E/P's 4-channel 8-bit ADC and 13 I/O pins suit industrial sensor interface applications such as multi-point temperature, pressure, or humidity monitoring. Each ADC channel can be routed to a different transducer, with the firmware performing linearization and threshold detection. The 5V operation and 5 MIPS throughput handle typical 10 Hz polling rates with headroom for digital I/O expansion. The 18-pin PDIP package simplifies repair and field replacement in industrial installations where through-hole components remain standard.

Appliance Control Boards
White-goods appliances (washing machines, dishwashers, microwave ovens) frequently use the PIC16C710-20E/P to coordinate keypad inputs, LED/LCD indicators, relay drivers, and analog sensor readings such as water level or temperature. The 8-bit Timer0 with prescaler drives simple time-base events for motor sequencing, while the 4-channel ADC monitors up to four analog signals simultaneously. The extended temperature grade supports under-hood or near-heater installations. Through-hole PDIP packaging aids manufacturing in regions where surface-mount lines are less common.

Consumer Electronics User Interfaces
The PIC16C710-20E/P is widely deployed in user-interface controllers for consumer products such as remote controls, toys, simple audio mixers, and learning devices. The 13 I/O pins connect directly to key matrices, LED indicators, and rotary encoders, while the 4-channel ADC reads potentiometers and battery voltage. The 5 MIPS throughput supports button-debouncing, mode logic, and LED-multiplexed display scanning. The PDIP form factor allows easy integration into plastic enclosures and hobbyist-grade products.

Battery-Powered Sensor Nodes
Although the PIC16C710-20E/P is OTP-based and lacks deep-sleep modes of newer MCUs, its low operating voltage and small code footprint make it suitable for wall-transformer-powered or replaceable-battery sensor nodes such as wireless thermometers, smoke detectors, and HVAC zone sensors. The brown-out reset protects against battery-end-of-life brown-outs, and the 4-channel ADC multiplexes multiple sensor inputs onto a single MCU. The 36 B RAM supports small FIFO buffers for sensor smoothing algorithms.

Educational and Hobbyist Projects
The PIC16C710-20E/P in 18-pin PDIP is a classic teaching microcontroller thanks to its breadboard-friendly through-hole form factor and rich instruction set documentation. Educational kits use it to teach ADC sampling, timer-driven event scheduling, GPIO control, and embedded C or MPASM assembly programming. Hobbyists favor the PDIP package for easy rework and debugging. Despite NRND status, the part remains widely referenced in textbooks and online tutorials, and Microchip's PICkit programmers support the family for continued learning use.

Diferensiator Kunci
- Doubles program memory and RAM versus the original part number (vsPIC16C711-20E/P)
- Extended -40C to +125C temperature grade for harsh environments (vsPIC16C710-20I/P)
- 20 MHz core versus 4 MHz slow-grade option (vsPIC16C710-04/P)
Catatan Desain
The PIC16C710-20E/P requires a stable 5V supply (4.5V-5.5V). Place a 0.1uF decoupling capacitor within 5 mm of the VDD pin (pin 14) and a bulk 10uF tantalum or aluminum capacitor on the same rail. The brown-out reset (BOR) is enabled by configuration fuse and protects against code corruption when VDD dips below the BOR threshold (typically ~4.0V). Estimated: total VDD current at 20 MHz with all peripherals active is under 15 mA; a 100 mA LDO such as MCP1700 or 7805 is adequate.
Route the oscillator traces (OSC1/OSC2 pins 16/15) as short as possible and keep them away from high-current switching traces. For crystal mode, place load capacitors (typically 15-33 pF) close to the crystal pins with symmetrical ground returns. The MCLR pin (pin 4) requires a 10 kohm pull-up to VDD; if not pulled, the device will not exit reset. Add a 100 nF capacitor from MCLR to ground to filter noise spikes.
Because the PIC16C710-20E/P uses OTP (One-Time-Programmable) EPROM, the program memory cannot be erased or rewritten after programming - verify firmware thoroughly before committing to production. The ADC requires the A/D conversion clock to be configured correctly; if too fast relative to the system clock, ADC readings become unreliable. Finally, the 18-pin PDIP variant has 13 usable I/O pins (RA0-RA4, RB0-RB7 minus the oscillator pins); do not exceed VIL/VIH specs on any input as it may latch-up.
Informasi Konformitas
