Native 0.9V MSP430L092 MCU enables smaller and greener products to run from a single battery

Other Parts Discussed in Post: MSP430L092

There is a growing trend within the electronics industry to develop smaller products that run from smaller batteries by consuming as little power as possible. However, system solutions for products running on a single battery today are often not fully optimized for achieving this goal. TI’s MSP430L092 MCU helps enable such products by offering ultra-low power consumption through its native 0.9V operation.

As a high level overview, there are two primary system-level solutions for products running from a single 1.5V alkaline battery. The first system uses multiple batteries, such as two AAA batteries. This directly causes a minimum physical size constraint as the product size is limited by the size of batteries. The second system only has one battery but requires either an external boost circuit or the use of an MCU with an integrated boost converter. The second system is not optimized for the lowest power consumption due to the extra boost circuit and also increases size and cost by adding additional components. In general, both systems have trade-offs, such as bigger product but lower power consumption, or smaller product but higher power consumption.

The native 0.9V operation of the MSP430L092 MCU can reduce both physical size and power consumption by eliminating boost circuitry while running directly from a single battery.  Full functionality of the MSP430L092 MCU is maintained within 0.9V to 1.65V range enabling full low-voltage system solutions.
