Interior of the Treo 680

Just the interesting side of the main board in the 680.

M-Systems MD8832-d1G-V3-X-P – 128MB DiskOnChip
Spansion S71PL064JB0BFW – 32Mbit pSRAM, 64Mbit Flash
Broadcom BCM2133KFBG – Baseband EDGE/GPRS/GSM chip
Intel 8270C5C312 CPU
SEC 634 BF75 ?

I suspected the sixteen pads (two rows of eight, though the upper row is occluded by the RF shielding) to the upper left of the PXA in the photo contain the JTAG points. This has been confirmed by Alex and Chris at Hack&Dev.

1 3.3 VDC   ; 16 TDO
2 NC        ; 15 NC
3 NC        ; 14 TCK
4 NC        ; 13 NTRST
5 NC        ; 12 NRESET
