No last-time-buy window remains open through the factory channel. For a BOM line that needs this exact order code — perhaps a legacy board in field service or a production run that cannot requalify a new MCU — the only supply path is the independent surplus and broker market. We source and quote this part to order against an RFQ; availability and current pricing are confirmed at quote time. The scorch mark tells you: once the last surplus reel is gone, this BGA footprint has no pin-compatible second source within the MSP430F5xx family that matches the same ball map. ## Peripherals and connectivity set On-chip peripherals include brown-out detect/reset, DMA, POR, PWM, and a watchdog timer. Communication interfaces cover I²C, IrDA, LINbus, SCI, SPI, and UART/USART.","metaTitle":"TI MSP430F5438AIZQWT 16-bit MCU, 25 MHz, 256 KB Flash","metaDescription":"Texas Instruments MSP430F5438AIZQWT 16-bit MCU, MSP430 CPUXV2 core at 25 MHz, 256 KB Flash, 16 KB RAM, 87 I/O, industrial temp -40°C to 85°C, 113-BGA.
