Product details

It is designed for battery-operated and industrial sensor applications where low power and a small code footprint are the primary constraints.

4 KB Flash — sizing the firmware budget

With 4 KB of program Flash, this MCU is a fit for simple control loops, state machines, and sensor readout tasks. The 256-byte RAM limits data buffering — expect to manage variables tightly and avoid large lookup tables. For designs that need more headroom, the MSP430G2xx family includes pin-compatible parts with up to 16 KB Flash and 512 B RAM, but the package and peripheral set remain the same.

At the low end, 1.8 V operation allows the MCU to run directly from a nearly depleted battery, extending system runtime. The 24 general-purpose I/O pins, all with interrupt capability, are enough for keypad scanning, LED driving, and simple parallel interfaces.

The 32-VFQFN package (5x5 mm body, exposed pad) is a compact surface-mount option for space-constrained PCBs.

It is ROHS3 compliant.

Frequently asked questions

What is the difference between MSP430G2303 and MSP430G2553?

The MSP430G2553 is a higher-density member of the same MSP430G2xx family, offering up to 16 KB Flash and 512 B RAM versus the 4 KB Flash and 256 B RAM of the MSP430G2303. Both share the same 16-bit CPU core, 16 MHz speed, 24 I/O, and 32-VQFN package option, so a board layout can be reused. The G2553 also includes a comparator and a higher-resolution ADC in some variants.

Is MSP430G2303IRHB32T compatible with LaunchPad?

The MSP430G2303IRHB32T uses the same MSP430G2xx core and is compatible with the MSP-EXP430G2 LaunchPad development kit, which supports all 14-, 20-, and 28-pin DIP and QFN devices in the G2xx series. The 32-VQFN package requires a separate adapter or breakout board for prototyping on the LaunchPad.
