Microchip Technology Rolls Out First PIC Microcontrollers Featuring Enhanced Mid-range 8-bit Core
Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, announced the first six members of the PIC16F193X family of microcontrollers (MCUs) featuring its enhanced Mid-range 8-bit core—the PIC16F1934, PIC16LF1934, PIC16F1936, PIC16LF1936, PIC16F1937 and PIC16LF1937. The new family extends Microchip’s PIC MCU 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.”
Additional 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 (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
- 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.
Development Tool Support
Microchip offers engineers a complete suite of standard development tools to design with the PIC16F193X microcontrollers, including the unified, feature-rich, user-friendly and free MPLAB IDE, along with a selection of HI-TECH C compilers. The HI-TECH Lite edition is a completely free, fully-functional compiler with no time limitations. For applications with limited program space, the Standard and PRO editions offer denser code and improved performance. There is also a variety of debugging hardware from the popular PICkit 3 Debug Express ($69.99), to the new In-Circuit Debugger, MPLAB ICD 3 ($219.99), and the MPLAB REAL ICE In-Circuit Emulator ($495.00). All of these tools can be purchased today at http://www.microchipdirect.com. More information on development tools is available at http://www.microchip.com/developmenttools. The PICkit 3 Starter Kit for the PIC16F193X enhanced core is in development, and is expected to be available in CQ3 2009.
