PL8351 Product Brochure

v1.0 1/23/2017

OVERVIEW

The PL8351 is an ultra-low-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 ARM Cortex M0 32-bit MCU, RTC and LCD driver in a single chip. PL8351 also support the

I2C, UART, PWM and timer interface for peripheral connection.

The PL8351 build in 128KB Flash for program space and 8KB internal SRAM memory for program. It also

integrates three ADC channels and EMP (Energy Meter Processor) for 1V2I meter application.

The PL8351 build in internal and AES accelerator. It supports AES128, 192 and 256 encryption and

decryption for security data communication. It reduces the program memory size requirement, MCU

operation load and makes it easy to integrate complicated designs. The programming is very easy and

supports ARM SWD two wire serial debug interface. No external voltage is required for programming.
