Single AA cell operted 16bit MCU with on-board LCD controller

There are some ultra portable and low cost applicatons which may have to work on single cell 1.5V AA/AAA battery. TI has launched a low cost 16 bit MCU with an integrated LCD controller for such requirements. Based on TI's MSP430 ultra-low power MCU core, the new AFE4110 features 16-kB ROM, 512-B RAM, a 4- x 12-segment LCD driver with charge pump, a high-accuracy oscillator, and additional features designed for digital thermometers, pedometers, thermostats and portable single alkaline battery devices.

The AFE4110 draws a low active current of 50 uA/MHz and sleep mode current of less than 0.3 uA.
Has highly accurate oscillator, eliminating the need for an external crystal.

The AFE4110 is available now in a 2.7-mm x 1.1-mm die. The AFE4110 is priced at $0.80 in quantities of 1,000.
