The new Atmel XMEGA B1 microcontrollers have that supports high-precision analog and a low-power LCD with character mapping. Go ahead, be a character
Atmel has introduced the Atmel XMEGA-B1 family of microcontrollers that is lower power, with support for LCD and high accuracy ADC.
The Atmel XMEGA-B1 is spec'ed at 100nA RAM retention mode, which retains RAM and can wakeup from any interrupt in 5µsec.
Features of the new Atmel XMEGA-B1 include:
The ultra-low-power LCD controller in the Atmel XMEGA-B1 microcontrollers supports up to 4x40 segments and has built-in ASCII character mapping. The LCD module draws only 3µA and includes LCD buffers and power supply. A SWAP mode allows flexible pinout configurations. Modes include programmable segment blinking scrolling text.
The Atmel AVR XMEGA-B1 family boasts high-precision analog peripherals, including two 12-bit analog-to-digital converters (ADCs) with programmable gain. The ADCs operate down to 1.6V operating voltage, and have a combined sample rate up to 4MSPS. Two 12-bit digital-to-analog converters (DACs) have high current outputs, while built-in current outputs enable embedded applications to remove external resistors or other constant current sources.
