Microchip Technology has announced a new family of low-cost 8bit flash PIC MCUs. The new 28- and 40-pin PIC16F722/3/4/6/7 (PIC16F72X) MCUs are capable of operation down to 1.8V and feature a 16MHz internal oscillator; up to 14 ADC channels; communication (SPI, I?C, AUSART) and two Capture, Compare and PWM (CCP) modules; plus the mTouch Sensing Solution peripheral.

The highly integrated devices are well-suited for a wide range of general-purpose applications in the appliance (blenders, refrigerators, dishwashers); consumer/home electronics (toys, cellphones, phone chargers, electric shavers, vacuum cleaners); industrial (digital water heaters, security systems, HVAC control); automotive (car audio, remote controls, power seats, lighting control), and other markets.

The PIC16F72X MCUs have an operating voltage range of 1.8-5.5V, with the low-power PIC16LF72X devices offering lower standby and other power-consumption specifications from 1.8V to 3.6V. Both variations feature a Timer1 Gate that runs from the internal 16MHz oscillator, providing ease in conditional event counting and measurements.

With up to 14 ADC channels, two CCP modules and communication peripherals, the MCUs increase design flexibility with the ability to interface with external devices such as environmental sensors, as well as provide additional system control and monitoring. The mTouch Sensing Solution peripheral makes it easy to add proximity sensing or capacitive touch-sensing user interfaces in place of mechanical buttons or switches, if designers so choose. Additionally, the mTouch peripheral can operate while the device is in "sleep mode," bringing further power savings to the user.

Development support
The new MCUs have integrated in-circuit debug and are supported by the MPLAB IDE, which is available as a free download from the company's Web site.

MPLAB REAL ICE in-circuit emulator support is expected to be available in the fourth calendar quarter of 2008.

The PIC16F722/3/6 and PIC16LF722/3/6 MCUs are available in 28-pin SPDIP, SOIC, SSOP and QFN packages; with prices starting at 91 cents each in 10,000-unit quantities. The PIC16F724/7 and PIC16LF724/7 MCUs are available in 40-pin PDIP, TQFP and QFN packages; with prices starting at $1.34 each in 10,000-unit quantities.

Samples are available today, with general sampling expected in April. Volume-production quantities of the devices can be ordered in April.
