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.
