The MSP430FR5957IDAR is a 16-bit MCU with MSP430 CPUXV2 core at 16 MHz, 32 KB FRAM, and 1 KB RAM. FRAM writes at bus speed, retains data without battery, and avoids EEPROM endurance limits. Supply range is 1.8 V to 3.6 V; temperature range is −40°C to 85°C.
The 12-bit ADC with 12 channels captures analog signals from thermocouples, potentiometers, or current shunts directly.
The MSP430FR5957IDAR runs at 16 MHz with the MSP430 CPUXV2 core, which is the standard speed for this FRAM-series MCU.
The MSP430FR5957IDAR is rated for −40°C to 85°C, covering industrial and automotive-cabin environments.
The datasheet for the MSP430FR5957IDAR is published by Texas Instruments and covers the full electrical specifications, timing diagrams, and application notes for the MSP430 FRAM series.
The MSP430FR5957IDAR is listed as RoHS compliant based on the TI product documentation; verify the specific date code for your region's exemption status.
