PIC16LC710-04/P - 8-Bit 4MHz MCU 896B OTP 18-PDIP | Microchip
The Microchip PIC16LC710-04/P is a member of the PIC16C7X family of low-cost, high-performance CMOS fully-static 8-bit microcontrollers, packaged in an 18-pin PDIP (through-hole) format with 896 bytes of One-Time-Programmable (OTP) program memory organized as 512 x 14 words, 36 bytes of RAM, and 13 general-purpose digital I/O pins. The core executes a reduced RISC instruction set at up to 4 MHz, delivering approximately 200 ns instruction cycle time, and integrates a multi-channel 8-bit analog-to-digital converter (ADC), brown-out reset (BOR) supervision, a Watchdog Timer (WDT) with its own on-chip RC oscillator, and three timer peripherals (Timer0 8-bit, Timer1 16-bit, Timer2 8-bit).
An 8-bit microcontroller is a single-chip computer built around an 8-bit data path, a small embedded CPU, on-chip non-volatile program memory (ROM/EPROM/Flash/OTP), volatile data memory (RAM), and a set of integrated peripherals such as timers, ADC, serial interfaces and I/O ports. The PIC16C7X sub-family specifically targets cost-sensitive embedded control applications by combining a Harvard RISC architecture with an integrated ADC and BOR in a small pin-count package. As a member of the broader hierarchy microcontroller -> embedded controller -> semiconductor, the PIC16LC710 occupies the low-pin-count, low-cost segment of the Microchip mid-range lineup.
The PIC16LC710-04/P is the low-voltage (LC) variant of the PIC16C710, qualified for 2.5V to 6.0V supply operation, which makes it suitable for battery-powered and 3.3V-only designs where the standard PIC16C710 (4.5V-6.0V) cannot operate. Key features distinguishing this part include the integrated 8-bit ADC (typically 4 channels on the 18-pin package), Power-on Reset, Power-up Timer, and Oscillator Start-up Timer that together allow reliable operation without external reset or power-sequencing components. The 13 I/O pins each have individually programmable direction control, supporting direct LED drive, switch matrix scanning, and simple bus interfaces.
Typical applications include low-cost sensor interfaces, battery chargers, small appliance controllers, smoke detectors, PIR motion sensor signal conditioning, LED lighting controllers, and educational/development platforms. The PIC16LC710-04/P is well suited when the application needs a few analog inputs, a small amount of program memory, and 3.3V system compatibility in a breadboard-friendly DIP package.
When designing with this MCU, note that OTP memory can be programmed only once, so consider PIC16F710-based Flash equivalents for prototyping and field-updatable production. Use the on-chip BOR to avoid undefined behavior at slow Vdd rise times, and decouple Vdd with a 100 nF ceramic capacitor placed within 5 mm of the supply pin.
