•

I

2

S and DDI with dedicated DMA

•

MP3, AAC, AC3/DD+, WMA9, PCM (WAV)

Codecs supported depend on software and may be different. 

LPE is supported on selected processor SKUs.

The Intel TXE

system contains a security engine and additional hardware security 

features that enable a secure and robust platform. 

See 

 for more details.

Security features include:

•

Isolated execution environment for crypto operations (SKU-enabled)

•

Supports secure boot – with customer programmable keys to secure code

The SoC requires TXE firmware in the PCU SPI flash image to function.

The platform controller unit is a collection of HW blocks, including SMBus, UART, 
debug/boot SPI, and Intel legacy block (iLB), that are critical to implement a Windows* 
compatible platform. See 

links to more information about each interface.

Key PCU features include:

•

SMBus Host controller – supports SMBus 2.0 specification
