  • RTCC

  • Five 16-bit timers

  • Three PWM outputs

  • 16 channels of 12-bit ADC

  • Two UARTs

  • SPI

  • I2C

  • Intelligent mTouch capacitive sensing Module

  • TQFP44,UQFN48, SOIC28 Packages

  • SOIC20, PDIP20, SSOP20 (PIC24F16KA only)

Powerful 16-bit CPU Core





The PIC24F32 has a powerful 17x17bit hardware multiply block, capable of 16x16 signed or unsigned multiply operations. Every multiply is single-cycle. The core also contains a 16-bit barrel-shifter capable single-cycle multi-bit arithmetic and logic shiftts. All multi-bit shift instructions require the Register Direct Addressing mode for both the operand (source) and destination (result).



Microchip PIC24F32KA Development Tools



The new Microchip PIC24F32KA304 Plug-In Module plugs into the Microchip Explorer 16 Development Board and provides real-time debugging of the PIC24F32KA. PDIP20 and PDIP28 devices are supported by the XLP 16-bit Development Board.



Microchip PIC24F32KA Pricing





"Pricing starts at $1.78 each, in 10,000-unit quantities."
