Product details

What this 16-bit MSP430 brings to a control board

Memory and peripheral fit — what the 8 KB / 512 B ceiling means

8 KB of Flash (8K x 8) and 512 x 8 RAM set a hard ceiling on firmware complexity. The 512-byte RAM is the tighter constraint: watch your stack depth and buffer allocation during interrupt-heavy operation. The 12-channel 10-bit ADC is a workhorse for reading potentiometers, thermistors, or current-sense resistors. No external mux needed for up to 12 single-ended inputs, and the 10-bit resolution (about 3 mV per count at 3.3 V reference) is adequate for most 1% tolerance sensing.

The 38-TSSOP package is a common footprint, so board respins for a pin-compatible sibling (like the MSP430G2553 with more Flash) are straightforward if your firmware outgrows the 8 KB ceiling.

Frequently asked questions

What is the closest pin-compatible alternative to MSP430G2444IDA38R?

Within the MSP430G2xx family, the MSP430G2553 offers more Flash (16 KB) and a similar peripheral set in the same 38-TSSOP package, making it a drop-in upgrade if firmware size becomes a constraint. Both share the same pinout and supply range.

Can MSP430G2444 be programmed with the MSP430G2 LaunchPad?

Yes, the MSP430G2 LaunchPad (MSP-EXP430G2) supports the entire MSP430G2xx family, including the G2444. The 14-pin DIP socket on the board won't fit the 38-TSSOP directly, but the Spy-Bi-Wire (SBW) debug header lets you program and debug the device on your own board using the LaunchPad's built-in debugger.
