What are the key features of XMS430FR2355TDBTR?
- 16-bit MSP430 core at up to 24 MHz with 32KB FRAM and 4KB SRAM enabling fast non-volatile writes at 105°C for harsh-environment data logging
- Integrated 12-bit ADC, 12-bit DAC, and programmable gain OpAmp/PGA on-chip for complete signal-chain solutions without external analog components
- Ultra-low-power MSP430 architecture with active current under 100 µA/MHz and multiple low-power modes for years of battery-powered sensor operation
What is XMS430FR2355TDBTR used for?
The XMS430FR2355TDBTR is designed for ultra-low-power sensor hubs, industrial flow meters, and smart energy monitoring equipment that require precise analog signal acquisition and non-volatile data storage in a single 16-bit MCU. Its integrated OpAmp/PGA and 12-bit ADC enable direct connection to bridge sensors and current transformers without an external front-end IC, reducing BOM cost significantly. The 32KB FRAM memory allows in-system data logging at full speed without the endurance limit of Flash, making it well suited for predictive maintenance recorders operating over -40°C to +105°C.

Frequently Asked Questions
How does 32KB FRAM in XMS430FR2355TDBTR improve data logging reliability compared to Flash-based MCUs?
FRAM (ferroelectric RAM) in the XMS430FR2355TDBTR supports virtually unlimited write cycles (>10^15 writes per cell) compared to the typical 10,000 to 100,000 Flash erase cycles, meaning high-frequency data logs written every few milliseconds remain reliable over the full product life without wear-levelling algorithms or external EEPROM backup.
What integrated analog signal chain features does XMS430FR2355TDBTR provide for direct sensor measurement?
The device integrates a 12-bit SAR ADC with multiple input channels, a 12-bit DAC for reference or output generation, and a programmable gain amplifier OpAmp/PGA that can amplify small sensor signals—such as thermocouple or bridge outputs in the millivolt range—before digitisation, eliminating the need for external op-amps in most sensor measurement designs.
Up to what temperature does XMS430FR2355TDBTR operate, and which certifications support industrial deployment?
The XMS430FR2355TDBTR is rated for operation up to 105°C ambient temperature, 30°C higher than the standard 85°C commercial grade, and supports JTAG boundary scan for production test automation. This extended temperature rating qualifies it for smart meters, industrial controllers, and under-hood automotive accessories where temperatures regularly exceed 85°C.
How does XMS430FR2355TDBTR compare to MSP430FR2355 for a design requiring confirmed production availability?
The XMS430FR2355TDBTR is the extended-temperature (105°C) tape-and-reel variant of MSP430FR2355 sharing the same 44-pin VQFN TSSOP footprint and identical 32KB FRAM / 4KB SRAM / 24 MHz specification, so migrating from the standard-temperature part requires only a BOM swap without any firmware or PCB layout changes.
