The Platform Controller Unit (PCU) is a collection of hardware blocks that are critical for 
implementing a Windows* compatible platform. These hardware blocks include:

•

•

— For boot FW and system configuration data Flash storage

•

•

The PCU also implements some high level configuration features for BIOS/EFI boot.

•

The key features of the individual blocks are as follows: SMBus Host Controller
— Supports System Management Bus (SMBus) 2.0 Specification
— No support for SMBus Slave functionality aside from the Host Notify Command

No TCO (Total Cost of Ownership) feature support

•

Universal Asynchronous Receiver/Transmitter (UART)
— 16550 controller compliant
— Reduced Signal Count: TX and RX only
— COM1  interface

•

Serial Peripheral Interface (SPI)
— For one or two SPI Flash, of up to 16MB size each, only. No other SPI peripherals 

are supported.

— Stores boot FW and system configuration data
— Supports frequencies of 20 MHz, 33MHz and 50MHz.
