The low-cost PIC24F KM family is the latest addition to Microchip Technology Inc.'s 16-bit PIC microcontroller (MCU) portfolio. The PIC24F family offers up to 16 KB Flash, 2 KB RAM, and 512B EEPROM, along with advanced analog integration, in low pin-count options for cost-sensitive automotive, consumer, medical, and industrial applications.
The PIC24F KM family provides a new level of integrated analog functionality, such as a 12-bit ADC with threshold detection, 8-bit DACs for analog control loops and precision comparator references, and op amps to assist in sensor amplifications. The new MCUs feature the new Multiple-output Capture Compare PWM Module (MCCP) and Single-output Capture Compare PWM Module (SCCP) peripherals, which include integrated timers and advanced PWM control to enable motor-control, power-supply and lighting applications. The MCCP and SCCP modules combine timers, input captures, output compare and PWM functions in a single time base for optimal flexibility. These modules include 16/32-bit timer support, and can operate from a high-speed clock for higher resolution due to their ability to operate asynchronously. They also allow for automatic operations during sleep mode, to optimize power consumption.
This is also the first PIC24 family to offer a Configurable Logic Cell (CLC) for increased on-chip interconnection of peripherals. The CLC module helps in creating custom real-time logic functions on-chip and is supported by the CLC configuration tool, which helps in coding the circuit graphically instead of in assembly or C, thereby saving time for the programmers.
