Connectivity includes I²C, SPI, UART/USART, LIN, IrDA, USB — 31 GPIOs in a 7x7 mm package. 8-channel 10-bit ADC. Supply 1.8 V to 3.6 V. -40°C to 85°C.
25 MHz clock handles USB full-speed packet handling. 6 KB RAM limits buffering; CPU must service endpoint FIFOs before overrun.
The MSP430F5509IRGZR is in an EOL hot lifecycle stage — the end-of-life process has started, and the last-time-buy window is open. It is not yet fully discontinued, but production will end soon. Source through independent distribution now to secure your BOM line.
Yes, the MSP430F5509IRGZR integrates a USB 2.0 full-speed peripheral with on-chip PHY, supporting device, host, and OTG modes. This eliminates the need for an external USB bridge chip.
The supply voltage range is 1.8 V to 3.6 V, covering single-cell Li-ion and standard 3.3 V logic rails.
The MSP430F5510IRGZR is pin-compatible and offers 32 KB Flash and 8 KB RAM, a direct drop-in upgrade. Verify firmware memory usage and linker script before substituting.
The datasheet is available from Texas Instruments under the base product number MSP430F5509. It covers the full MSP430F5xx family with USB — register maps, electrical characteristics, and application notes for USB, ADC, and low-power modes.
