Microchip announced the expansion of its 28-/40-pin PIC16F72x microcontroller (MCU) family with two new 20-pin devices. The PIC16F(LF)720 and PIC16F(LF)721 feature low power consumption, making them suitable for low-power and battery-powered applications. The addition of smaller pin-count options, with up to 7 KB of self-write Flash programme memory and a temperature indicator module, extends the MCU family into even lower-cost applications.
The new devices integrate an 8-bit analog-to-digital converter (ADC), a capture/compare PWM module and a number of serial communication peripherals, such as I2C, SPI and AUSART. The MCUs target applications including appliances such as blenders, refrigerators and dishwashers; consumer/home electronics such as TV remote controls, toys, phones and set-top boxes; and in the industrial market in digital water heaters, security systems and humidity sensors; as well as in automotive remote lock systems, power seats, level sensors and lighting control.
The PIC16F(LF)720/1 are general-purpose MCUs which offer integrated control peripherals incorporating the latest features. In addition to the self-write program memory for remote firmware updates, they integrate a temperature indicator module enabling measurement of the temperature of the surrounding environment.
Additionally, the integrated communication peripherals can be used for serial data transfer between other devices on or off the PCB. With packages as small as a 4 x 4 mm QFN, these MCUs can be used in space-constrained applications.
