PIC16F688-I/P 8-Bit Flash Microcontroller with ADC and USART DIP-14 (PIC16F688-I/P DIP IC)
The PIC16F688-I/P is a high-performance, 8-bit Flash-based microcontroller from Microchip's mid-range family, providing an extensive feature set in a compact 14-pin package. It features a powerful RISC architecture with 35 single-word instructions. This IC includes 7KB of Flash program memory, 256 bytes of SRAM, and 256 bytes of high-endurance EEPROM. Key highlights include an 8-channel 10-bit Analog-to-Digital Converter (ADC), a Universal Synchronous Asynchronous Receiver Transmitter (USART/UART) for hardware serial communication, and two analog comparators. With its precision software-selectable internal oscillator (up to 8MHz) and NanoWatt technology, it is an ideal solution for space-constrained applications requiring both analog sensing and robust serial connectivity.
This IC is primarily used in serial-to-analog converters, automotive sensor nodes, and handheld data collection devices. It is a highly versatile component for Arduino electronics projects in India for building DIY wireless communication modules, advanced multi-sensor data loggers, and smart automation controllers that require hardware UART in a small 14-pin DIP footprint.
