OVERVIEW
Description
The ZON P3L/P3
(MAX71334L/MAX71335L) metering SoC
(systems on chip) integrates dual 32-bit
processors for polyphase metering
applications. It contains 256KB flash (ZON
P3) or 128KB flash (ZON P3L), 12KB RAM
and a single-cycle 32 x 32 + 64 multiplier.
The application processor (CPU) is a 32-bit
MAXQ 30 core. The metrology processor is
a proprietary compute engine (CE), a 32-bit
RISC processor dedicated to computing the
metering parameters from voltage and
current samples.
