Product Overview
The Texas Instruments MSP430FR5994 is a mixed-signal FRAM microcontroller built around a 16-bit RISC core operating up to 16 MHz. Its embedded FRAM provides nonvolatile memory with up to 256 KB device-family capacity, 125 ns per-word write speed, 64 KB bulk write time in 4 ms, and 10^15 write-cycle endurance.
For low-power embedded systems, the device operates from 1.8 V to 3.6 V, with active-mode current of 118 uA/MHz. Low-power modes include 500 nA LPM3 standby with VLO, 350 nA LPM3.5 standby with an RTC clocked by a 3.7-pF crystal, and 45 nA LPM4.5 shutdown current.
The MSP430FR5994 includes 8 KB total RAM and, on MSP430FR599x devices, a LEA signal-processing accelerator with 4 KB RAM shared with the CPU. Peripheral support includes six DMA channels, six 16-bit timers, a 32-bit hardware multiplier, 32-bit and 16-bit CRC, a 16-channel analog comparator, 12-bit ADC inputs, AES acceleration, eUSCI serial ports, UART or I2C bootloader support, and capacitive-touch capability on all pins.
Package options cover NFBGA-87, LQFP-80, LQFP-64, and VQFN-48 formats for board layouts requiring different pin counts and footprints.
