MCU Inherently Operates at 0.9V, Enables Multiple Apps to Run from a Single Cell Battery

MCU runs at 0.9VTexas Instruments announced what is said to be the industry’s first true 0.9-V microcontroller (MCU). The MSP430L092 MCU inherently operates at 0.9-V, including the entire analog and digital logic. Because it operates at 0.9-V, the chip does not require an on-board boost converter, lowering the entire system’s power consumption and reduces the need for external circuitry. This allows developers to run applications such as electric toothbrushes, razors, toys and security devices off of a single-cell battery, ranging from AAA to coin cell. The MCU also offers programmable analog building blocks that can be configured as five different peripherals. Three 0.9-V MCU variations with up to 2 KB RAM and 2 KB ROM provide multiple choices for a path to production. The Integrated Analog Functions Pool (A-POOL) can serve as an analog-to-digital converter (ADC), digital-to-analog converter (DAC), system voltage supervisor (SVS), temperature sensor or comparator, eliminating the need for external components. The programmable A-POOL enables the various analog peripheral configurations to run sequentially without user interaction. Tool kits, including external EEPROM, and ROM-flow process guide help rapidly move from development to final production. Its low-power consumption of 45 uA and wake-up time of <5 us combined with true 0.9-V operation, enable optimized battery usage.
