Device identity and memory envelope
The MSP430F5254IZQER is a 16-bit microcontroller from the MSP430F5xx family, built around the MSP430 CPUXV2 core running at 25 MHz.
On-chip peripherals include brown-out detection, DMA, POR, PWM, and a watchdog timer. Connectivity options span I²C, IrDA, LINbus, SCI, SPI, and UART/USART, covering common serial buses for sensor and actuator interfaces.
Supplied in an 80-VFBGA package (MICROSTAR JUNIOR, 5x5 mm body), this is a fine-pitch BGA requiring careful PCB layout — the 0.50 mm ball pitch typically demands a multi-layer board with microvias for fan-out. The tape-and-reel packaging suits automated assembly lines.
Lifecycle reality
Texas Instruments has marked the MSP430F5254IZQER as obsolete. For existing BOM lines, sourcing runs through independent distribution channels — quantities are lot-specific and confirmed at RFQ.
