Prolific PL8333
The PL8333 series of ultralow power mixed-
signal processors consist of several devices featuring
different sets of peripherals targeted for energy meter
applications. It integrate analog front end and fixed
function DSP solution with an enhanced 8052 MCU
core, RTC and LCD driver in a single part. The measure-
ment 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 is a
built-in 16-bit timer, LCD segment drive capability and
hardware multiplier.
The PL8333 integrates three PGA with gain
setting from 1x to 32x. Three 24-bit sigma-deltas A/D
converters guarantee precision captured data and
enough resolution need.
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 inte-
grate complicated designs.
The programming is very easy and support
different ways. (SPI or JTAG) No external voltage
needed when programming.
