Microchip Technology has announced the first six members of the PIC16F193X family of microcontrollers featuring Microchip's enhanced Mid-range 8-bit core - the PIC16F1934, PIC16LF1934, PIC16F1936, PIC16LF1936, PIC16F1937 and PIC16LF1937. The new family extends Microchip's PIC microcontroller portfolio of over 550 compatible members, targeting a wide variety of applications in the appliance, consumer, industrial, medical and automotive markets. The family's increased memory and core capabilities deliver enhanced support for both C and Assembly programmers, and "LF" family members feature Microchip's nanoWatt XLP Technology - for extreme Low Power consumption - enabling designs to achieve world-leading battery lifetime. Continuing in the PIC MCU tradition of integrating extensive peripherals, the new family offers Direct LCD drive and support for mTouch capacitive touch-sensing solutions.

"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."

Features of the PIC16F193X family include:

Flash program memory up to 14 KB

Data RAM up to 512 Bytes

256 Bytes Data EEPROM

LCD drive (96 segments)

nanoWatt XLP Technology on the "LF" versions, resulting in 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

mTouch Sensing Solutions peripheral for capacitive touch sensing (16 channels, with support for up to 64 buttons)

32 MHz internal oscillator

Up to 5 Enhanced Capture Compare PWM peripherals with independent time base

/> Reduced Interrupt latency

16-level hardware stack, with overflow/underflow interrupt

Low-power 1.8 to 5.5V operation, including full analog peripheral operation

Master SPI/I2C and EUSART support for RS-232/RS-485, as well as LIN support

Up to 14 channels of 10-bit Analog-to-Digital Conversion (ADC)

Two rail-to-rail input comparators with 555 Timer operation

4x8-bit and 1x16-bit timers, with eXtreme Low Power Real-Time Clock (RTC) support

Robust and reliable operational monitors, such as Power-On Reset (POR), Brown-out Reset (BOR) and low-power Watchdog Timer (WDT) With a total of 49 instructions

The PIC16F193X microcontrollers optimize program code and data handling, while increasing efficiency and reducing clock cycles. Future devices with the enhanced Mid-range 8-bit core, offering increased memory and additional I/O, are expected to be released later this year.
