7×24-bit sigma-delta ADC array — the distinguishing feature
Its program memory is 512 KB of Flash with 16 KB of RAM. What sets this part apart is the peripheral set: seven 24-bit sigma-delta analog-to-digital converters, plus an additional 8×10-bit ADC, a segment LCD controller, and a DMA engine. The 90 I/O lines and connectivity options (I²C, IrDA, LINbus, SPI, UART/USART) make it a fit for polyphase energy metering, industrial process control, and precision sensor front ends that need simultaneous multi-channel conversion.
Package and footprint
Housed in a 128-LQFP (20×14 mm body) — a standard fine-pitch QFP that routes easily on a four-layer board. Surface-mount, so no through-hole rework; the 0.5 mm pitch needs a decent soldering profile but is well within the capability of any contract assembler.
Lifecycle and sourcing
That means no last-time-buy clock is ticking; it remains a viable choice for both prototype builds and production runs.
