Polyphase metering MCU with six sigma-delta channels
Its defining feature is the integration of six 24-bit sigma-delta analog-to-digital converters, purpose-built for polyphase energy metering and precision measurement applications where simultaneous multi-channel acquisition is required. Program memory is 512 KB of Flash, paired with 32 KB of RAM, providing enough headroom for metrology firmware stacks, calibration tables, and data logging. Peripheral set includes brown-out detect/reset, DMA, LCD driver, POR, PWM, and watchdog timer.
Sigma-delta converter count and metering fit
Six 24-bit sigma-delta converters are integrated for polyphase metering.
The 128-LQFP package has a 20x14 mm body.
