Its program memory is 96 KB of FRAM — a non-volatile storage technology that combines the fast write speed and low power of RAM with the data retention of Flash, with essentially unlimited write endurance. This makes it a strong fit for applications that log data frequently, update firmware over the air, or need to maintain configuration state without a separate EEPROM.
96 KB FRAM — the endurance and write-speed advantage
The 96 KB FRAM program memory is the headline feature here. Unlike conventional Flash, FRAM writes at bus speed without a page-erase cycle, so the MCU can treat a portion of program space as data-logging or configuration storage without wearing out the memory. For a design that writes calibration constants every power cycle or streams telemetry into a circular buffer, this avoids the 100k-cycle endurance ceiling of typical embedded Flash. The 2K x 8 RAM handles stack and scratchpad data; the FRAM handles the rest.
16 MHz CPUXV2 core with 48 I/O and 12-bit ADC
The 16 MHz clock rate on the MSP430 CPUXV2 core is enough for moderate sensor fusion loops, Modbus/RS-485 polling, and real-time control with PWM peripherals. The 48 I/O lines in the 64-LQFP package give room for parallel LCD interfaces, keypad matrices, or multiple sensor inputs. The 12-channel, 12-bit ADC (A/D 12x12b) covers analog front-end tasks like thermocouple, strain-gauge, or current-sense readings without an external converter.
1.8V to 3.6V supply — single-rail battery or regulated bus
The brown-out detect and POR peripherals are integrated, so the reset circuit needs only a pull-up and a decoupling cap.
The MSP430FR5888IPMR carries an Obsolete product status.
