Eight-bit core microcontrollers

Microchip has announced the first six members of the PIC16F193X family of microcontrollers featuring enhanced mid-range eight-bit core - the PIC16F1934, PIC16LF1934, PIC16F1936, PIC16LF1936, PIC16F1937 and PIC16LF1937.

The family extends the company’s PIC microcontroller portfolio of over 550 compatible members, targeting a wide variety of applications in the appliance, consumer, industrial, medical and motor vehicle markets.

The family’s increased memory and core capabilities deliver enhanced support for both C and Assembly programmers, and LF family members feature the company’s nanoWatt XLP technology - for extreme low power consumption. The family offers direct LCD drive and support for mTouch capacitive touch-sensing.

Additional features of the 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 current of 500 nA and low-power 32 kHz Timer1 oscillator current of 600 nA at 1.8 V; mTouch sensing peripheral (16 channels, with support for up to 64 buttons); 32 MHz internal oscillator; up to five 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 5.5 V 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; two rail-to-rail input comparators with 555 timer operation; 4x8-bit and 1x16-bit timers, with eXtreme low power real-time clock support; robust and reliable operational monitors, such as power-on reset.
