PL8331 Description
The PL8331 series of ultra-low power mixed-signal processors consist of several devices featuring different sets of peripherals targeted for energy meter applications. They integrate analog front end and fixed function DSP solution with an enhanced 8052 MCU core, RTC and LCD driver in a single part. The measurement core includes active, reactive, apparent energy calculations, voltage, current RMS, and frequency...
