GENERAL DESCRIPTION
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. 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, UART, and an SPI, I2C and JTAG interface. It reduces the program memory size requirement and makes it easy to integrate complicated designs.
