16-bit MSP430 with 48 KB Flash — what this MCU carries
The MSP430F2481TRGCR: 16-bit ultralow-power microcontroller from the MSP430F2xx family. Runs at 16 MHz, with 48 KB Flash, 256 B information memory, and 4 KB RAM. Specified for -40 to 105 °C. On-chip peripherals include brown-out detect/reset, POR, PWM, and watchdog timer. Connectivity covers I²C, IrDA, LINbus, SCI, SPI, and UART/USART.
EOL hot — last-time-buy window is open
The MSP430F2481TRGCR carries an EOL hot lifecycle stage. Texas Instruments has announced end-of-life for this device; the last-time-buy order window is active but closing. For a BOM that depends on this exact order code, the procurement action is to place a lifetime buy quantity now, before the LTBT expires and the part moves to non-cancelable/non-returnable surplus only. No official successor order code appears in the lifecycle record. If the design cannot migrate to a newer MSP430F2xx or MSP430F5xx variant, the sourcing strategy is a one-time buy against the remaining LTBT window, with the balance covered through independent distribution channels. We quote the part to order against an RFQ; availability and current pricing are confirmed at quote time.
48 I/O and mixed-protocol connectivity
With 48 GPIOs and peripherals including I²C, SPI, UART, and LIN, this MCU can bridge a Modbus RTU gateway, SPI temperature sensor, and I²C EEPROM.
