PL8331

PROLIFIC PL8331

Metering IC with 3x 24bit sigma delta ADCs and 8052-core MCU

2.4-5V supply, ultra low power, temp compensation, wake-up function, LCD 4 x 25 segment output

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 different (= multiple) ways. (SPI or JTAG) No external voltage is needed for programming.
