产品概述 返回TOPu9x嘉泰姆

The CXEP2342L electricity meter systems-on-chip (SoC) integrate dual 32-bit processors for demanding single-phase metering applications with 128KB or 64KB flash, 8KB RAM, and a single-cycle 32 x 32 + 64 multiplier. A low-power metering mode allows metering in the presence of neutral disconnect tampering. The low-power, dedicated compute engine (CE) handles high-rate metrology processing and a 32-bit MAXQ30 MPU core handles other application functions including communications and display control.
