PL8331中文资料1P Metering SoC w Ultra-low power (4x25 LCD, 1 UART)数据手册Prolific规格书

描述 Description

OVERVIEWThe PL8331 is an ultralow power mixed-signal processors consist 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 for energy billing and for any necessary application. Also included are a built-in 16-bit timer, LCD segment drive capability and hardware multiplier.
The PL8331 integrates three PGAs with gain settings from 1x to 32x. Three 24-bit sigma-deltas A/D converters guarantee precision in captured data and enough needed resolution.
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 multiple ways. (SPI or JTAG)
No external voltage is needed for programming.
