Low-power 8-bit MCU med LED-driver

Microchip lancerer nye MCU'er, der baseret på firmaets nanoWatt XLP-teknolog. Blandt nyhederne er en MCU, der inkluderer on-chip LCD-driver modul (in english).

Microchip announces the introduction of the PIC18F ‘K90’ and the PIC18F ‘K22’ families of 8-bit microcontrollers, the latest MCUs based on its industry-leading low power technology, nanoWatt XLP.

The ‘K90’ represents the industry’s first and only ultra low power MCU family to include an on-chip LCD driver module capable of driving LCDs up to 192 pixels. Both new families support 1.8 to 5.5V operation, offer a 12-bit A/D converter, and Microchip’s innovative mTouch capacitive touch-sensing technology, along with many other peripheral configurations.

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.

Plug-In Modules (PIMs) for the PIC18LF45K22 (part No MA160014, $25) and PIC18F87K22 (part No MA180028, $25) MCUs are also new. The PIMs can be used with the PIC18 Explorer Board (part No DM183032, $99.99). 

A PIM for the PIC18F87K90 MCU is also announced, today (part No MA180027, $25).  This can be used with the PICDEM LCD 2 Demo Board (part No DM163030, $125), or stand-alone in a custom application.
