The PIC18F ‘K90’ family represents a significant expansion to Microchip’s high-end 8-bit LCD microcontroller offerings and is ideal for driving large, segmented LCDs while consuming very low power. The family comes in 64- and 80-pin packages, with memory options that range from 32 KB to 128 KB of Flash memory, up to 4 KB of RAM and 1 KB of on-chip EEPROM.
The PIC18F ‘K22’ MCUs provide features such as operation from 1.8 to 5.5V, numerous communication channels, 8 to 128 KB Flash memory, and peripherals for mTouch™ capacitive touch-sensing applications. Other features include a 12-bit Analog-to-Digital Converter (ADC), multiple PWMs and additional timers.
Both the ‘K90’ and ‘K22’ families are suitable for use in home automation, appliance and industrial applications, as well as the medical and automotive markets. The ‘K22’ family is offered in 20- to 80-pin packages with 8- to 128-kbyte of program memory. The ‘K90’ family comes in 64- to 80-pin packages and between 32- and 128-kbyte program memory.
All of the new MCUs feature nanoWatt XLP technology for eXtreme Low Power operation, with industry leading sleep currents down to 20nA. In addition, the MCUs provide a greater than 50% improvement in active current over previous generations.
