Prolific PL8331
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, 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 differ-
ent (= multiple) ways. (SPI or JTAG)
No external voltage is needed for programming.
