Product details

EOL hot — last-time-buy window is open

This part carries an eol_hot lifecycle status; Texas Instruments has announced end-of-life and a last-time-buy window is active. No official successor order code is listed in available records.

Memory sizing for the firmware budget

With 8 KB of Flash and 512 bytes of RAM, the MSP430G2433IPW28 is sized for a single-purpose firmware image — a sensor polling loop, a simple PID controller, or a Modbus slave on the UART. There is no room for a full RTOS or a large comms buffer; the 10-bit ADC results and LINbus frame handling must fit within the 512-byte RAM. The internal oscillator eliminates an external crystal, saving two I/O pins for other functions.

Frequently asked questions

What is the closest pin-compatible alternative to the MSP430G2433IPW28?

The MSP430G2553 (same 28-TSSOP package, same pinout, 16 KB Flash, 512 B RAM, same peripheral set including the 8-channel 10-bit ADC) is a direct drop-in candidate. Verify the firmware fits within 8 KB if you are migrating down, but the G2553 offers headroom for additional code.
