描述 Description

OVERVIEWThe PL8333 is an ultralow power mixed-signal processors consisting of several devices featuring different sets of peripherals targeted for energy meter applications. It integrates 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 measurements. This information can be used as energy billing and any necessary application. Also included is a built-in 16-bit timer, LCD segment drive capability and hardware multiplier.The PL8333 integrates three PGA with gain setting from 1x to 32x. Three 24-bit sigma-deltas A/D converters guarantee precision captured data and enough resolution need.The microprocessor functionality includes a single-cycle 8052 core, a real-time clock, 2UARTs, and an SPI, I2C and JTAG interface. It reduces the program memory size requirement and makes it easy to integrate complicated designs.
The programming is very easy and supports different ways. (SPI or JTAG) No external voltage needed when programming.
