• Small 20?pin TSSOP package to minimize PCB footprint in space?constrained designs.

Typical Applications

• Battery?powered sensor nodes requiring frequent non?volatile logging, long service life, and minimal idle current consumption for extended field operation.
• Portable medical monitors that need fast wake?up, frequent data writes to FRAM, and low power draw to preserve battery life between measurements.
• Industrial metering and utility endpoints where high write endurance and reliable non?volatile storage reduce maintenance and support long data retention.
• Human?machine interfaces and compact control panels that benefit from integrated serial peripherals and small package size to lower BOM and board area.

MSP430FR2353TDBT Advantages vs Typical Alternatives

The FRAM?based MCU offers faster write speeds and far greater write endurance than comparable flash?based microcontrollers, which reduces system latency for frequent data logging. Its ultra?low standby current and wide operating voltage make it more suitable for battery?operated designs than many higher?power 8/32?bit alternatives. The small 20?pin package and integrated eUSCI serial blocks also lower BOM count and board area versus devices that require external EEPROM or larger packages.
