Four 24-bit sigma-delta ADCs and an LCD driver — a metering-class MCU
This is a part specced for polyphase energy metering, industrial instrumentation, and flow computers where you need to sample multiple precision analog channels and drive a local display without extra chips.
25 MHz CPUXV2 — what the core speed means for the conversion chain
At 25 MHz the CPUXV2 has enough headroom to process four simultaneous 24-bit sigma-delta conversion results, run the LCD controller, and handle protocol stacks (I²C, SPI, UART) without stalling. The 16-bit RISC architecture with a hardware multiplier keeps the math tight for RMS and power calculations. If you are coming from an 8-bit metering MCU, this core speed lets you do the DSP-like accumulation in firmware rather than an external coprocessor.
Package and pin count for a mixed-signal layout
Housed in a 100-pin LQFP (14x14 mm body), the part brings out 62 general-purpose I/O. The LQFP footprint is straightforward for two-layer boards, though the four sigma-delta inputs and LCD segment lines benefit from a dedicated ground plane under the analog section. The surface-mount package is MSL 3 — standard floor-life handling for reflow assembly.
