The MAX71314/MAX71315 integrate dual 32-bit processors for demanding single-phase metering applications with 256kB flash (MAX71315) or 128kB flash (MAX71314), 12kB RAM, and a single-cycle 32 x 32 + 64 multiplier. The user processor (MPU) is a 32-bit MAXQ®30 core. The metrology compute engine (CE) is a 32-bit processor dedicated to computing the metering parameters from voltage and current samples. The MAXQ® USB-to-JTAG/1-Wire® adapter can be used to interface either the JTAG or 1-Wire port on MAXQ microcontrollers to a PC for development and debugging.
