MSP430FR2355TDBTR Key Features

• FRAM nonvolatile memory ?? enables low?energy, high?speed writes for frequent data logging without flash write delays.
• 16?bit MSP430 core ?? delivers efficient code density and lower instruction overhead compared with 8?bit alternatives.
• Low supply range ?? supports systems operating from 1.8 V to 3.6 V, improving compatibility with common battery chemistries.
• Integrated analog and digital peripherals ?? ADC, timers and eUSCI modules reduce BOM and PCB area for compact designs.
• Deterministic wake and write behavior ?? FRAM eliminates long erase cycles so systems can log data more predictably than flash?based MCUs.
• Multiple serial interfaces ?? UART, SPI and I2C support enables easier integration with sensors and communication modules.

Typical Applications

• Battery?powered industrial sensors that require frequent nonvolatile data logging and longer field lifetime with reduced power draw.
• Handheld instrumentation where fast nonvolatile writes and deterministic behavior reduce user wait time during measurement storage.
• Smart metering endpoints that need reliable data retention across power cycles and many write cycles over the product life.
• Embedded controllers for motor drives and actuators where integrated timers, ADC and serial ports minimize external components and PCB area.

MSP430FR2355TDBTR Advantages vs Typical Alternatives

The device offers FRAM memory, which writes faster and uses less energy than conventional flash. It delivers more deterministic write behavior and higher endurance, which reduces firmware complexity for frequent logging compared with flash?based MCUs. The 16?bit MSP430 core gives more efficient code density than many 8?bit parts, and the integrated ADC, timers and multi?protocol eUSCI peripherals lower BOM and board size versus using separate analog front?ends and comms chips.
