New 8-bit PIC MCUs with capacitive touch sense interface and LCD interface

Microchip has announced six members of the PIC16F193X family of microcontrollers (MCUs) with new 8-bit core. The new MCUs parts are PIC16F1934, PIC16LF1934, PIC16F1936, PIC16LF1936, PIC16F1937 and PIC16LF1937.

These new MCUs boast increase memory, better core, low power features and also integrate touch interface and LCD display interface/drive.

"We are pleased to announce the first family of microcontrollers based upon our enhanced Mid-range 8-bit core," said Steve Drehobl, vice president of Microchip's Security, Microcontroller and Technology Development Division. "Building upon the worldwide customer acceptance of Microchip's existing Mid-range 8-bit products, the new devices enable new levels of functionality at lower system cost."

The key features of the PIC16F193X family are

Flash program memory up to 14 KB
Data RAM up to 512 Bytes
256 Bytes Data EEPROM
LCD drive (up to 96 segments)
Sleep currents of 90 nA, Watchdog Timer (WDT) current of 500 nA, and low-power 32 kHz Timer1 oscillator current of 600 nA, all at 1.8V
