16 bit low power large memory microcontrollerMicrochip Technology added nine new members to the PIC24F 16-bit microcontroller (MCU) family which features low power (2.6 µA standby current) and large-memory (up to 256 KB Flash and 16 KB RAM). This 16-bit MCU includes an integrated Charge Time Measurement Unit (CTMU) peripheral, which — along with the royalty-free mTouch Sensing Solution software development kit — enables designers to add a capacitive-touch user interface without any external components. The company's Graphics Software Library is also included. In advanced applications, the PIC24FJ256GA1 family allows the use of all onboard peripherals, by enabling designers to map them to the pin they desire through the “Peripheral Pin Select” pin-mapping function. Enhanced peripherals provide up to four UARTs, three SPI ports and three I2C ports. The family maintains pin, peripheral and software compatibility with all of the companys’s general-purpose 32-bit MCU and 16-bit MCU/DSC families. Additional features include 23 independent timers, and development tool support via the company's MPLAB IDE, the MPLAB C30 C compiler, MPLAB REAL ICE emulation system, MPLAB ICD 2 in-circuit debugger and the MPLAB PM3 universal device programmer. The nine-member PIC24FJ256GA1 family is offered in 64-, 80- or 100-pin TQFP packages, and pricing starts at $3.39 each in 10,000-unit quantities.
