Microchip PIC16F690T-E/SS 8-Bit Microcontroller Technical Overview and Application Guide

The Microchip PIC16F690T-E/SS is a high-performance, cost-effective 8-bit microcontroller from Microchip Technology’s extensive PIC® MCU portfolio. Built on an enhanced mid-range core with a 2-stage instruction pipeline, this device operates at speeds up to 20 MHz, delivering a robust 5 MIPS performance. Housed in a 20-pin Shrink Small Outline Package (SSOP), it is designed for space-constrained applications while offering a rich set of peripherals.

At the heart of this MCU is 4 KB of Flash program memory, 256 bytes of EEPROM data memory, and 256 bytes of SRAM. Its non-volatile memory supports up to 1,000,000 erase/write cycles (Flash) and 1,000,000 erase/write cycles (EEPROM), ensuring reliable data retention and firmware updates over the product’s lifetime.

A key strength of the PIC16F690 lies in its versatile analog and digital peripherals. It features a 10-bit Analog-to-Digital Converter (ADC) with up to 12 channels, enabling precise measurement of multiple analog signals. For motor control and power management applications, it includes two analog comparators and a Capture/Compare/PWM (CCP) module. Additionally, the Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART) supports serial communication protocols like UART, SPI, and I2C, facilitating easy interfacing with sensors, displays, and other peripherals.

The microcontroller integrates an internal precision 8 MHz internal oscillator, which can be calibrated to ±1% accuracy, reducing the need for an external crystal and saving both board space and cost. Its operating voltage ranges from 2.0V to 5.5V, making it suitable for both battery-powered and line-operated devices. With its nanoWatt Technology, the PIC16F690 excels in low-power applications, featuring multiple power-saving modes like Sleep, where current consumption can drop to as low as 100 nA.

Typical applications include automotive systems, consumer electronics, industrial control, and sensor interfaces. Its robust peripheral set and compact form factor make it ideal for embedded designs requiring analog signal processing, user interface control, or low-power operation.
