Microchip’s low-pin-count 16-bit Extreme Low Power PIC MCUs now feature an on-chip 12-bit ADC, EEPROM, intelligent Mtouch capacitive sensing and the capability to run from a 5V supply.

Featuring sleep currents down to 20nA, for which all XLP PIC MCUs are known, the PIC24F32KA304 MCUs provide designers with the most versatile low-power products available today – giving them an edge in designing industrial, automotive, medical, utility metering, white goods and many other applications.

The PIC24F32KA304 family expands upon the PIC24F16KA range by adding twice as much Flash program memory and 30 per cent more RAM, which provides even more support for wireless-communication protocol stacks.

Additionally, the numbers of timers and Pulse-Width Modulators were tripled; the numbers of UART, I2C and SPI channels doubled; the analogue-to-digital converter resolution quadrupled to 12-bits; and the pin count increased to 44-pins, over the PIC24F16KA range.

The PIC24F32KA304 MCUs’ intelligent Mtouch sensing module includes a Charge Time Measurement Unit (CTMU) that performs automated scan in sleep mode, enabling extremely low-power capacitive sensing.

Further, as many touch-sensing applications are battery powered, this CTMU reduces current, thereby conserving even more battery power.

As many automotive and white-goods applications require operation up to 5V, these MCUs simplify power-supply design by eliminating the need for discrete voltage regulators, and providing full analog performance up to 5V.

Microchip also announced the availability of the PIC24F32KA304 Plug-In Module for the Explorer 16 Development Board Alternatively, 20- and 28-pin PDIP packages are supported by the XLP 16-bit Development Board.

The MPLAB IDE, MPLAB C Compiler for PIC24 MCUs and dsPIC DSCs, MPLAB ICD3 In-Circuit Debugger and Pickit 3 Debugger/Programmer are also available.

The PIC24F(FV)32KA304 MCU is available in 44-pin TQFP and 8 x 8mm QFN packages, as well as a 48-pin 6 x 6mm UQFN package.

The PIC24F(FV)32KA302 MCU is available in 28-pin SOIC, SSOP, SPDIP and 6 x 6mm QFN packages.

The lowest pin-count options include the PIC24F(FV)16KA301 MCUs, which are available in 20-pin PDIP, SOIC and SSOP packages.

The PIC24FXXKA3XX products operate from 1.8 to 3.6V, while PIC24FVXXKA3XX versions operate from 2 to 5V.
