Microchip Technology has launched the first six members of the PIC16F193X family of microcontrollers featuring 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 improved battery lifetime.
The new family offers Direct LCD drive and support for mTouch capacitive touch-sensing solutions. Additional features of the PIC16F193X family include:
- Flash program memory up to 14kB
- 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 90nA, Watchdog Timer (WDT) current of 500nA, and low-power 32kHz Timer oscillator current of 600nA, all at 1.8V
- mTouch Sensing Solutions peripheral for capacitive touch sensing (16 channels, with support for up to 64 buttons)
- 32MHz 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 1.8V 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
- 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.
