25 MHz MSP430 CPUXV2 with 64 KB flash — the BOM-fit read
The MSP430F5247IZQER is a Texas Instruments 16-bit MCU from the MSP430F5xx series, built around the MSP430 CPUXV2 core running at 25 MHz.
80-BGA MICROSTAR JUNIOR — the board-level reality
The 80-BGA MICROSTAR JUNIOR package (5x5 mm) is the tightest footprint in the MSP430F5xx lineup for this I/O count — 53 I/O in a 0.5 mm pitch ball grid array. The small body and fine pitch demand a controlled reflow profile and X-ray inspection for voiding under the BGA.
Industrial temp grade and peripheral set
The on-chip peripherals include a 12-channel 10-bit ADC, brown-out detect, POR, DMA, PWM, and a watchdog timer. Serial connectivity covers I2C, IrDA, SPI, and UART/USART, so it can bridge to sensors, displays, and radio modules without external level shifters in most cases.
Texas Instruments lists the MSP430F5247IZQER as Obsolete. The part is sourced through independent distribution channels — sealed reels with consistent date-codes are available, but quantities are lot-specific and confirmed at RFQ. For new designs, a current MSP430F5xx or MSP430FRxx device in a more common package (LQFP, QFN) is the practical migration path.
