The PL8331 series of ultralow power mixed-signal

processors consist of several devices featuring

different sets of peripherals targeted for energy

meter applications. They integrate analog front

end and fixed function DSP solution with an en-

hanced 8052 MCU core, RTC and LCD driver in a

single part. The measurement core includes ac-

tive, reactive, apparent energy calculations, volt-

age, 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 PL8331 integrates three PGAs with gain set-

tings 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, I

2C 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 differ-

ent (= multiple) ways. (SPI or JTAG)

No external voltage is needed for programming.
