Large-memory 16-bit MCUs

Microchip has announced nine mode members of the PIC24F 16-bit microcontroller family that have 2.6 µA standby current, up to 256 KB flash and 16 KB RAM in these 16-bit microcontrollers.

It is claimed to be the first 16-bit MCU family with an integrated charge time measurement unit peripheral, that, along with the mTouch sensing solution software development kit, enables designers to add a capacitive-touch user interface without any external components.

When combined with the company’s free graphics software library, engineers have access to a complete user interface.

For I/O flexibility in advanced applications, the 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.

The enhanced peripherals of the PIC24FJ256GA1 family provide up to four UARTs, three SPI ports and three I²C ports to expand control capabilities and eliminate the space and cost of support chips.
