Breakdown cost estimations



Apparently manufactured by Hitachi. At least there is a Hitachi logo on the PCB, which can be seen on this picture.
Also, it says "HCL" which could stand for Hitachi Cambridge Laboratory (HCL)

Overclocking possibilities?

Boot Flash (SPI)

Although Ultra Mobile ICH7-U claims to be missing SPI interface, it appears this device contains the system boot code.

LED/IR Remote Controller

Cypress calls this chip a 'low-speed USB Peripheral Controller' but in aTV it has nothing to do with the external USB port.
It is an 8-bit microcontroller with 8K of FLASH and 256 bytes of RAM, also a possible watch-dog timer for the system.
Its various GPIOs go to the header that the front baby-board connects to.
