Product details

16 MHz MSP430 core — 32 KB Flash, 4 KB RAM, 12-channel ADC

The MSP430G2755IDA38R: The 12-channel 10-bit ADC samples multiple analog inputs through a single part.

38-TSSOP package — 32 I/O in a compact footprint

Housed in a 38-TSSOP (6.10 mm width, 0.240" body), this part gives you 32 general-purpose I/O pins in a surface-mount package. The Flash retains data across the full range; no derating needed for the 16 MHz speed at the temperature extremes.

The MSP430G2xx ecosystem has broad toolchain support — TI's Code Composer Studio, IAR Embedded Workbench, and the Energia open-source framework all target this core. ROHS3 compliant per the current revision, so it passes European and California regulatory requirements without an exemption certificate.

Frequently asked questions

Is MSP430G2755IDA38R compatible with MSP430G2553?

Both are 16-bit MSP430G2xx MCUs in the same 38-TSSOP footprint with the same pinout for the core I/O and supply rails. The G2755 doubles the Flash from 16 KB to 32 KB and adds the 12-channel 10-bit ADC versus the G2553's 8-channel 10-bit ADC. If your firmware fits in 16 KB and you do not need the extra ADC channels, the G2553 is a drop-in cost-reduction alternative; otherwise the G2755 gives you the headroom without a board spin.

How to program MSP430G2755IDA38R using TI tools?

The MSP430G2755 uses the standard Spy-Bi-Wire (SBW) two-wire JTAG interface, accessible through TI's MSP-FET or the cheaper MSP-EXP430G2 launchpad. Code Composer Studio and IAR Embedded Workbench both support the MSP430G2xx family; the Energia open-source IDE also works for rapid prototyping. The internal oscillator runs at 16 MHz out of reset, so no external clock is needed to start programming.
