Product details

16 MHz MSP430 core with 4 KB Flash — what it fits

It runs the MSP430 CPU16 core at 16 MHz and carries 4 KB of Flash program memory with 256 bytes of RAM. This memory footprint targets firmware that stays under the 4 KB threshold — sensor calibration, simple protocol bridges, or a single control loop — without room for a full RTOS or large lookup tables.

24 I/O and serial connectivity for sensor and control nodes

No on-chip ADC is present, so analog inputs require an external converter.

Industrial temperature grade, 28-TSSOP footprint

The 28-TSSOP package (0.65 mm pitch, 4.4 mm body width) is a straightforward hand-solderable or reflow-compatible surface-mount footprint.

ROHS3 compliant. For dual-sourcing planning, the MSP430G2xx family includes density and peripheral variants that share the same 28-TSSOP footprint.

Frequently asked questions

Is MSP430G2303IPW28R obsolete or active?

It carries an Active product status on the manufacturer's record. This is a current-production part, not an obsolete or NRND device.

Does MSP430G2303IPW28R have a built-in ADC?

No. The peripheral list includes brown-out detect, PWM, and watchdog timer, but no on-chip ADC module. Any analog input requires an external ADC or comparator.
