The 512 x 8 RAM handles stack and variable data, while 12 general-purpose I/O lines and an 8-channel 10-bit ADC connect to sensors, switches, and analog inputs. ## FRAM program memory — no field-update penalty The 1 KB FRAM (1K x 8) is the standout feature. Unlike Flash or EEPROM, FRAM writes at bus speed without a page-erase cycle, so the MCU can log data or update firmware in the field with zero write-cycle overhead. For a battery-powered sensor that must store readings every few seconds, this saves microamps compared to a Flash part that would need a charge pump for each write. The 512 x 8 RAM is modest — enough for a small control loop or state machine, but tight for buffering large packets. Plan your stack and variable footprint accordingly. ## 24-VQFN package — rework considerations The 24-VQFN (3x3 mm) with exposed thermal pad is a compact package that saves board space but needs a careful rework profile. The pad under the QFN sinks heat fast — a standard hot-air station with a fine nozzle will lift the part clean if you preheat the board first.","metaTitle":"MSP430FR2100IRLLR 16-bit MCU, 16 MHz, 1 KB FRAM, 24-VQFN","metaDescription":"Texas Instruments MSP430FR2100IRLLR 16-bit MCU with 16 MHz core, 1 KB FRAM, 512 B RAM, 12 I/O, 8x10-bit ADC, -40°C to 85°C, 24-VQFN.
