Prolific PL8332
The PL8332 are designed for ultralow power
mixed-signal processors consisting 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. Its measurement core
includes active, reactive, apparent energy calculations,
voltage, current RMS, and frequency measurements. This
information can be used as energy billing and any neces-
sary application. Also included is a built-in 16-bit timer,
LCD segment drive capability and hardware multiplier.
The PL8332 integrates three PGA with gain set-
ting from 1x to 32x. Three 24-bit sigma-deltas A/D con-
verters 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 re-
quirement and makes it easy to integrate complicated
designs. The programming is very easy and supports dif-
ferent ways. (SPI or JTAG). No external voltage needed
when programming.
