Product details

16 MHz, 4 KB Flash — what the memory budget means for your BOM

The 8-channel 10-bit ADC captures analog inputs directly, saving an external converter on a mixed-signal board.

The MSP430G2xx family has broad distribution support, and the base product number MSP430G2333 is a standard catalog item. For dual-sourcing, a pin-compatible sibling in the same 32-VQFN footprint with larger Flash (e.g., MSP430G2553) can serve as a drop-in upgrade if the firmware later outgrows 4 KB — verify the peripheral set matches your driver code before swapping.

Frequently asked questions

What is the core processor of MSP430G2333IRHB32T?

The core is the MSP430 CPU16, a 16-bit RISC architecture designed for ultra-low-power operation. It runs at 16 MHz and includes a hardware multiplier for efficient signal processing.

Can MSP430G2333IRHB32T replace MSP430G2553?

Both are 16-bit MSP430G2xx MCUs in the same 32-VQFN package, so the footprint matches. The G2553 offers 16 KB Flash and 512 B RAM versus 4 KB Flash and 256 B RAM on the G2333. If your firmware fits within the smaller memory and the peripheral set (ADC channels, serial interfaces) aligns, a drop-in replacement is possible. Verify the ADC resolution — the G2333 has 10-bit while the G2553 has 10-bit as well — and check the GPIO count (24 I/O on both).
