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.
