The 1K x 8 RAM handles call stacks and scratchpad buffers without eating into the FRAM endurance budget. Serial connectivity includes I²C, SPI, and UART, plus IrDA and LINbus for automotive or industrial subnets. ## FRAM: no EEPROM, no wear-leveling headache The 16 KB FRAM program memory is the headline feature. For a firmware engineer, this means the bootloader and application can share the same memory array without the usual write-latency gymnastics. The 1K x 8 RAM is conventional SRAM — use it for stack and volatile data, not persistent storage. With the internal oscillator and brown-out reset enabled, the standby current is typically in the low microamp range — a key spec for the battery-life calculator on a wireless sensor node. The POR and BOR peripherals are on-chip, so no external supervisor IC is needed for basic power-fail detection. The 28-TSSOP package is a common footprint, so second-sourcing within the MSP430 FRAM family is straightforward if a pin-compatible density variant is needed later.","metaTitle":"TI MSP430FR5728IPWR 16-bit MCU, 8 MHz, 16 KB FRAM, 28-TSSOP","metaDescription":"Texas Instruments MSP430FR5728IPWR 16-bit MCU with 8 MHz CPUXV2, 16 KB FRAM, 1K x 8 RAM, 10-ch 10-bit ADC, I²C/SPI/UART.
