Dallas, Texas – Taking aim at low cost MCU apps that run from a single-cell battery, Texas Instruments Incorporated (TI) today introduced what it claims is the industry’s first true 0.9-V microcontroller (MCU), a part of its ultra-low-power MSP430 MCU family.
According to Jennifer Barry, MSP430 MCU product marketing manager, unlike existing MCUs that claim 0.9-V technology, TI’s MSP430L092 MCU inherently operates at 0.9-V, including the entire analog and digital logic.
“Because it operates at 0.9-V, the MSP430 MCU does not require an on-board boost converter,” she said, “lowering the entire system’s power consumption and reduces the need for external circuitry required by traditional solutions.
“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 MSP430L092 also offers programmable analog building blocks that can be configured as five different peripherals.
She said the device’s Integrated Analog Functions Pool (Figure 1 below ) can be configured to serve multiple functions: 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 to reduce overall bill of materials.

“The programmable A-POOL means the various analog peripheral configurations can run sequentially without user interaction,providing increased flexibility,” said Barry.
The device is being supplied in two 0.9-V MCU variations – MSP430L092 (RAM) and MSP430C092 (ROM) – with up to 2kB RAM and 2kB ROMprovide multiple choices for a path to production.
She said ultra-low-power consumption of 45 microamperes (active) and wake-up time of less than 5 microseconds combined with true 0.9-V operation enable optimized battery usage.
In addition to free software, comprehensive application notes, code libraries and community support, new tool kits are available to help developers fully leverage the benefits of this industry-first device.
The tool kits, including external EEPROM, and ROM-flow process guide are designed, said Barry, to help rapidly move from development to final production
The new MSP430L092 MCUs are priced from $0.85 at 10K units. The supporting MSP-TS430L092 ($99) and MSP-FET430U092 ($149) development tools are immediately available to customers. To learn more, go to www.ti.com/.
