Microchip have added two new devices to their 8-bit family of microcontrollers. The 14 and 20-pin PIC16LF1554 and PIC16LF1559 MCUs incorporate two 10-bit A/D converters (up to 17 channels max) and hardware Capacitive Voltage Divider modules for reading sensor values including capacitive sensing inputs.
These MCUs also include up to 14 KB Flash/512 Bytes RAM and use a 32 MHz internal oscillator. Two output modules provide programmable PWM signals and communications are handled by I2C, SPI and EUSART interfaces. These devices are also eXtreme Low Power (XLP) compliant with an active supply current of 35 µA/MHz and sleep current of 30 nA.
