Product Overview
The MSP430FR2111 is a Texas Instruments ultra-low-power FRAM microcontroller built around the MSP430FR21xx/MSP430FR2000 16-bit RISC architecture. It supports operation up to 16 MHz from a 1.8 V to 3.6 V supply range, with the minimum supply voltage restricted by SVS levels. Memory resources for this part include 3.75 KB of program FRAM, 1 KB of RAM, and FRAM endurance rated at 10^15 write cycles.
Peripheral resources include a 10-bit, 8-channel single-ended ADC rated for 200 ksps, a 1.5 V internal reference, and an enhanced comparator with an integrated 6-bit DAC reference. Timing and control functions include one 16-bit Timer_B3 with three capture/compare registers, one 16-bit counter-only RTC counter capable of LPM3.5 operation, and a 16-bit CRC module.
Clocking is provided by a 16-MHz DCO with FLL, ±1% DCO accuracy at room temperature with the on-chip reference, a 10 kHz VLO, and 32 kHz LFXT support. The part is supplied in TSSOP (16) 5 mm × 4.4 mm and VQFN (24) 3 mm × 3 mm packages, with assembly guidance including 4.7 µF to 10 µF bypass and 0.1 µF decoupling on the DVCC/DVSS power pair.
