MCUs: Microchip enhances its PIC MCUs with new mid-range 8-bit Core

Chandler, Az. – Microchip Technology Inc. has just introduced the first six members of the PIC16F193X family of microcontrollers (MCUs) featuring its enhanced Mid-range 8-bit core.

Including the PIC16F1934, PIC16LF1934, PIC16F1936, PIC16LF1936, PIC16F1937 and PIC16LF1937, the new family extends Microchip's PIC MCU portfolio to 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.

The new devices include flash program memory up to 14 KB; data RAM up to 512 Bytes; 256 Bytes Data EEPROM; LCD drive (up to 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.

In addition to peripherals for capacitive touch sensing (16 channels, with support for up to 64 buttons), the devices incorporate a 32 MHz internal oscillator; up to 5 Enhanced Capture Compare PWM peripherals with independent time base; reduced Interrupt latency and a 16-level hardware stack, with overflow/underflow interrupt.

There is also master SPI/I2C and EUSART support for RS-232/RS-485, as well as LIN as well as up to 14 channels of 10-bit Analog-to-Digital Conversion (ADC) Two rail-to-rail input comparators with 555 Timer operation and 4×8-bit and 1×16-bit timers, with extreme low power Real-Time Clock (RTC) support.

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.

The PICkit 3 Starter Kit for the PIC16F193X enhanced core is in development, and is expected to be available in CQ3 2009. To learn more, go to www.microchip.com/enhanced.
