I've started looking at the CPU sheet, and as result placement of our 16
individual CPU parts. We have the ability to place these parts on
different sheets, so they can be associated with the circuitry which
uses them, and avoid some sheet-to-sheet global labels.
As a starting point, I'm proposing that the CPU gets split onto the
sheets indicated below, which for some of the sheets already populated
will mean adding the relevant CPU part (such as audio / usb).
MEM :
a - memory
i - SDRAM
j - NAND
SIM :
b - SDIO
I/O :
d - EINT
e - UART (GSM & GPS)
n - IIC (Audio, pmu, debug connector)
LCM :
f - ADC
g - LCD
USB :
k - USB
AUDIO :
m - IIS
CPU :
h - CAMERA (general IO / device setup)
l - Timer
o - Clock+control+jtag
CPU-Power :
p Power
Bluetooth & WLAN :
c - SPI
Thoughts?
Dave
