Six 16-bit ADCs — the headline feature for metrology designs
Six independent 16-bit sigma-delta ADCs. Each channel can sample simultaneously, which is essential for accurate phase-angle and harmonic measurement in three-phase energy meters.
Industrial temperature range and supply flexibility
Rated for -40°C to 85°C ambient. Supply range of 1.8 V to 3.6 V. Internal oscillator eliminates an external crystal for the CPU clock.
Connectivity and peripheral set
On the communication side, the MCU supports I²C, SPI, UART/USART, IrDA, and LINbus — enough to talk to an external RF module, a PLC modem, or a serial display. 68 general-purpose I/O pins are available in the 100-LQFP package, leaving room for a keypad matrix, alarm relays, and status LEDs alongside the metering front-end.
