The 80-VFBGA package (5×5 mm) suits space-constrained boards, and the –40 to 85 °C operating temperature range covers industrial environments. On-chip peripherals include I²C, SPI, UART, IrDA, DMA, PWM, and a brown-out reset — enough to handle serial communication and real-time control without external glue logic. ## 25 MHz CPU clock — bus timing and wake-up latency The 25 MHz clock yields a 40 ns instruction cycle. The internal oscillator saves board space but drifts with temperature. ## Memory sizing for firmware and data buffers 128 KB Flash and 32 KB SRAM are available. The SRAM supports a DMA buffer or a TCP/IP stack. ## Obsolete — sourcing reality and the BOM decision Texas Instruments has marked the MSP430F5258IZQER as obsolete. No official successor is published. For existing BOMs, the part is sourced to order against an RFQ.","metaTitle":"Texas Instruments MSP430F5258IZQER 16-bit MCU, 25 MHz, 128 KB Flash, Obsolete","metaDescription":"Texas Instruments MSP430F5258IZQER MSP430F5xx 16-bit MCU at 25 MHz with 128 KB Flash and 32 KB SRAM.
