Seven 24-bit sigma-delta ADCs — the reason to pick this MSP430
What sets it apart from the rest of the MSP430F6xx line is the peripheral set: seven independent 24-bit sigma-delta analog-to-digital converters on-chip. The 62 general-purpose I/O lines, plus I²C, SPI, UART, IrDA, and LINbus connectivity, give it enough interface headroom to talk to an external communications module or display while the sigma-delta converters run continuously.
Package and footprint — 100-LQFP with 14x14 mm body
Housed in a 100-pin LQFP with a 14x14 mm body, the MSP430F67791IPZR uses a fine-pitch QFP footprint that is straightforward for two-layer boards if you route the analog and digital domains carefully. The supplier device package is 100-LQFP (14x14), so the land pattern matches the standard JEDEC outline for that body size. Surface-mount only — no through-hole option.
