Seiko Epson has introduced the low-power S1C31W74 microcontroller, meant to extend the battery life in mobile devices by integrating 32-bit flash memory. The MCU is based on ARM's Cortex-M0+ processor design.
Atmel is sampling the SAML21 line of low-power microcontrollers, based on the ARM Cortex-M0 core design, in a bid to take MCU market share from STMicroelectronics and Texas Instruments. The new chips are fabricated with a 110-nanometer complementary metal-oxide semiconductor process and will be available in volume production quantities in September.
Silicon Labs has introduced the Precision32 SiM3L1xx line of low-power microcontrollers, employing the Cortex-M3 design from ARM Holdings. Applications include asset tracking, home automation, personal medical devices, smart meters, utility monitoring and wireless security, the company said. The parts are available in production quantities.
An energy-efficient microcontroller built around the ARM Cortex-M4F processor core can offer digital signal processor functions, such as floating-point instructions, Andreas Koller writes in this technical article. DSP-equipped MCUs can be used in a variety of low-power applications, such as ultrasonic water metering and security systems that can detect the sound of breaking glass, Koller notes.
The Cortex-M0+ 32-bit microcontroller design unveiled Tuesday by ARM Holdings uses significantly less power than 8-bit and 16-bit MCUs, the company says, and can operate for years without recharging its power source. The highly energy-efficient chip is expected to find its way into many applications, such as appliances, lighting and automobiles, helping realize the "Internet of things" concept of extending Internet connectivity beyond computers and handsets. Freescale Semiconductor and NXP Semiconductors are the first two chipmakers to license the Cortex-M0+.
