TI samples lowest power MSP430 microcontroller
Texas Instruments is sampling its Wolverine its lowest power microcontroller family.
The MSP430FR59xx microcontrollers consume less than 100µA/MHz in active power consumption. There is a 360nA in real-time clock mode with fast wakeup time of 6.5µs.
This compares with Freescale Semiconductor’s Kinetis KW01 Cortex-M0+ based processor which consumes just 40µA/MHz in typical conditions.
TI’s FRAM-based microcontrollers are targeted at low power applications such as wireless sensing, energy harvesting and smart metering.
Up to 64kB embedded FRAM, direct memory access (DMA) engine, 12-bit analogue-to-digital converter (ADC), analogue comparator, capacitive touch IOs and UART, SPI and I2C serial interfaces.
There is also hardware for AES encryption, memory protection and a hardware accelerated random number generator (DRNG).
Typical battery-powered applications spend most time in standby modes, using analogue-to-digital converters (ADCs) to measure signals, recording data to non-volatile memory and active CPU processing for communications, decision making and simple math.
The embedded FRAM non-volatile memory consumes 250x less energy per bit and writing more than 100 times faster compared to flash- and EEPROM-based microcontrollers, said the supplier.
MSP430FR59xx samples and development kits are available today at www.ti.com/fr59-pr-lp and are fully compatible with all code and software resources developed for the MSP microcontroller platform.
Resources include 1,000+ code examples, ULP Advisor software code analysis tool, Grace graphical initialization software and MSP430Ware with MSP430 microcontroller peripheral libraries.
The MSP-TS430RGZ48C target board is available from TI’s eStore for easy programming.
