8-bit MCUs include self-write flash program memory

Microchip Technology Inc. has expanded its  28-/40-pin PIC16F72X microcontroller family with two additional 20-pin devices—the PIC16F(LF)720 and PIC16F(LF)721.

These MCUs offer up to 7 KB of self-write flash program memory, a temperature-indicator module, an 8-bit analog-to-digital converter, a capture/compare PWM module, and various serial communication peripherals, such as I2C, SPI and AUSART.

The integrated MCUs enable engineers to reduce board size, component count and overall cost for a variety of applications in the appliance (such as blenders, refrigerators, dishwashers); consumer/home electronic (TV remote controls, toys, phones, set-top boxes); industrial (digital water heaters, security systems, humidity sensors); and automotive (remote lock systems, power seats, level sensors, lighting control) markets.

The PIC16F(LF)720/1 are general-purpose MCUs that provide integrated control peripherals with self-write memory and a temperature indicator module. The self-write flash program memory can be used to perform remote firmware updates, while the temperature-indicator module provides a means for measuring the temperature of the surrounding environment.

Integrated communication peripherals can be used for serial data transfer between other devices on or off the PCB. These MCUs are available in packages as small as a 4 mm x 4 mm QFN, to enable space-constrained applications.

The PIC16F(LF)720/1 MCUs are available in a 20-pin, 4 mm x 4 mm QFN package, as well as 20-pin PDIP, SOIC and SSOP packages.
