FRAM-based 16-bit MCU for low-power sensor and control
Its program memory is 1 KB of FRAM, a non-volatile memory that combines the fast write speed and low power of RAM with the retention of Flash, and it includes 512 bytes of RAM.
FRAM endurance and write speed — the practical difference
For a design that logs sensor data or updates configuration parameters frequently — say, every few seconds for years — this eliminates the need for wear-leveling algorithms or external EEPROM. The 1 KB program memory limits code size, so the part fits applications like a simple thermostat, a pulse counter, or a one-wire temperature monitor where the firmware stays under 1 KB.
Peripherals and I/O for small-footprint designs
The MSP430FR2100IPW16 provides 12 general-purpose I/O pins and an 8-channel, 10-bit ADC.
