16 bit MCU with 16KB FRAM from TI for data logging and wireless remote sensing apps

Texas Instruments Incorporated has announced 16-bit microcontroller chips integrated with non-volatile ferroelectric random access memory (FRAM) . In the new MSP430FR57xx FRAM MCUs chips, the source code program and data can be written more than 100 times faster and uses 250 times less power compared to flash memory and EEPROM-based microcontrollers. The on-chip FRAM allows data retention in all power modes and supports more than 100 trillion write cycles, far higher than NOR flash. FRAM based MCUs are more reliabe and last longer than NOR flash based MCUs in applications where frequent data logging is required for long time.

Key features and benefits of the MSP430FR57xx FRAM microcontrollers:
Operate at 100uA/MHz in active mode and 3 uA in real-time clock mode
Unified memory allows developers to easily change memory partitioning between program, data and cache in software, providing inventory management and system cost savings
Enables reliable remote software upgrades - especially over the air - to provide cheaper, easier software upgrade paths for device manufacturers
Integrated FRAM densities up to 16kB as well as analog and connectivity peripheral options, including 10-bit ADC, 32-bit hardware multiplier, up to five 16-bit timers and multiple enhanced SPI/I2C/UART buses.
Enables intelligent batteryless RF connectivity solutions
FR57XX MCUs are built on TI's advanced low power, 130nm embedded FRAM process

Pricing and availability: The new MSP430FR57xx microcontrollers start at $1.20 at 10K units, and samples and tools are immediately available. The MSP-EXP430FR5739 Experimenter's Kit is $29.
