16bit PIC MCU tweaked for cost-sensitive apps

Microchip Technology has recently debuted the latest addition to their 16bit PIC microcontroller portfolio, the low cost PIC24F "KM" family. The company's latest line of microcontrollers offer up to 16KB Flash, 2KB RAM and 512B EEPROM, along with advanced analogue 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 analogue functionality such as a 12bit ADC with threshold detection, 8bit DACs for analogue control loops and precision comparator references, and op amps to assist in sensor amplifications. The PIC24 "KM" MCUs are the first to 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 16/32bit 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 optimise power consumption.

In addition to advanced peripheral integration, the "KM" family includes support for both 3V and 5V applications. Many customers prefer 3V operation for portable, battery-operated applications, and the 3V "KM" products all include eXtreme Low Power XLP for optimal battery life. The PIC24F "KM", with its extreme low power and advanced analogue integration, is an excellent solution for customers working on cost-sensitive applications, such as flow meters, smoke detectors, stepper and BLDC motors, LED dimming, battery charging, environmental sensors and portable disposable medical products.

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.

The PIC24F "KM" MCUs operate from 1.8 to 3.6V, while PIC24FV "KM" versions operate from 2 to 5.5V. The PIC24F(V)16KM204, PIC24F(V)08KM204 and PICF(V)16KM104 are offered in 44-pin TQFP and QFN packages, as well as 48-pin UQFN packages. The PIC24F(V)16KM202, PIC24F(V)08KM202, PIC24F(V)16KM102 and PIC24F(V)08KM102 are available in 28-pin SOIC, SSOP, SPDIP and QFN packages. The PIC24F(V)08KM101 is offered in 20-pin SOIC, SPDIP and SSOP packages. All of these new MCUs are available today for sampling and volume production, in 10,000-unit quantities.
