Low Pincount PIC MCUs

Microchip Technology Inc.’s three new PIC® Flash 8-bit microcontrollers (MCUs) provide unprecedented system-level performance and cost effectiveness in 8- and 14-pin packages. The PIC16F684, PIC16F688 and PIC12F683 MCUs offer designers up to 7168 bytes of Flash program memory and several peripheral options with integrated nanoWatt technology. These new devices are suitable for a range of applications, including home appliances, battery-operated or handheld products, sensors, interface, automotive and general-purpose control functions.

With the PIC16F684, PIC16F688 and PIC12F683 MCUs, Microchip’s customers have an easy, pin-compatible migration path from the classic 8- and 14-pin devices to these new “enhanced” low pincount products. In addition, these devices offer the familiar x14 architecture, along with standardized features that include a wide operating voltage of 2-V to 5.5-V and on-board EEPROM data memory.

Standard analog peripherals on the three new PIC devices include up to eight channels of 10-bit A/D for easy measurement of analog signals, and up to two comparators as general-purpose building blocks for analog input/output control. The PIC12F683 comes with Microchip’s standard capture/compare/PWM module, and the PIC16F688 features a EUSART peripheral that will support standard RS232/485-type communications as well as the LIN protocol, which is popular in automotive body electronics and dashboard controls.

The PIC16F684 features an Enhanced Capture Compare module with deadband control, up to four outputs and emergency shutdown, all of which improves control capabilities in applications such as electronic motor control and power supplies.
