PL8332

1P Metering SoC w Ultra-low power (4x32 LCD, 2 UART);

OVERVIEWThe PL8332 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. Its 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 are a built-in 16-bit timer, LCD segment drive capability and hardware multiplier.\nThe PL8332 integrates three PGA with gain setting from 1x to 32x. Three 24-bit sigma-deltas A/D converters guarantee precision in captured data and adequate resolution requirement.\nThe 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 sizerequirement and makes it easy to integrate complicated designs. The programming is very easy and supports different ways. (SPI or JTAG). No external voltage is needed when programming.\nGENERAL S\n

PL8332G is a monolithic 36V, 3.1A step-down switching converter. PL8332G integrates a 36V 79mΩ high side and a 36V, 62mΩ low side MOSFETs to provide 3.1A continuous load current over a 6.5V to 36V wide operating input voltage with 33V input over voltage protection. Peak current mode control provides fast transient responses and cycle-by-cycle current limiting. Programmable soft-start prevents inrush current at power-up.
