- Integrated 12-bit ADC plus 12-bit DAC and OpAmp/PGA enable complete analogue signal acquisition and generation without external converters
- 16-bit MSP430 CPU at 24 MHz with 105°C rating and 44 I/O pins suits demanding industrial and automotive sensor-node designs
Applications
XMS430FR2355TPTR is designed for ultra-low-power sensor nodes and metering applications that require frequent analogue sampling with 12-bit precision and reliable data retention through power interruptions. The integrated FRAM allows high-cycle parameter logging without wear concerns, making it suitable for smart energy meters, portable medical monitors, and industrial wireless sensor nodes. Its 105°C temperature rating and 44-pin I/O also qualify it for under-hood automotive sensing and factory-floor data-acquisition modules.

Frequently Asked Questions
What type of non-volatile memory does XMS430FR2355TPTR use, and how does FRAM differ from Flash in write endurance?
XMS430FR2355TPTR uses 32 KB of FRAM (Ferroelectric RAM), which supports more than 100 trillion write cycles compared to roughly 10,000 to 100,000 cycles for standard Flash. This effectively unlimited endurance means the FRAM can be used as both program memory and a high-speed data log without wear-levelling firmware, simplifying designs that write sensor readings or event counters at rates up to 24 MHz.
How does the integrated OpAmp/PGA on XMS430FR2355TPTR reduce external component count in a sensor front-end?
The on-chip programmable gain amplifier and OpAmp allow the MCU to amplify weak sensor signals—such as a 10 mV bridge output from a strain gauge—directly before routing them to the 12-bit ADC, eliminating a discrete op-amp IC plus 4 to 6 passive gain-setting resistors. This saves board space and BOM cost while keeping the signal path within the MCU's controlled power domain for consistent performance across the -40°C to 105°C operating range.
What is the maximum operating temperature of XMS430FR2355TPTR, and which industrial environments does that cover?
XMS430FR2355TPTR is rated to 105°C maximum junction temperature, qualifying it for extended industrial environments such as motor control enclosures, solar inverter housings, and factory-floor sensor modules where ambient temperatures routinely reach 85°C. Standard commercial MCUs rated to 85°C would require additional thermal management or derating in those environments.
How many I/O pins does XMS430FR2355TPTR provide, and how does 44 pins compare to the needs of a multi-sensor node?
The device provides 44 general-purpose I/O pins in its quad flat package. A typical multi-sensor node using 4 SPI sensors (4 pins each), 1 UART debug port (2 pins), 4 analogue inputs, and 8 status LEDs needs roughly 30 pins, leaving 14 pins spare. This overhead accommodates future expansion or alternate peripheral configurations without moving to a larger and more expensive MCU.
When does XMS430FR2355TPTR make a better choice than a Cortex-M0+ MCU for a battery-powered data logger?
XMS430FR2355TPTR is preferred when the design demands sub-microamp data-retention current and high write-cycle endurance for continuous sensor logging on a coin cell. Its FRAM retains data below 1 µA, and the MSP430 active mode draws as little as a few hundred microamps at 24 MHz compared to several milliamps for a typical Cortex-M0+. For designs logging to Flash every second over a 10-year life, FRAM eliminates the Flash wear problem entirely and removes the need for external EEPROM.
