PSP Go Teardown and Chip Analysis
- Sony is sourcing chips from a variety of manufacturers. Samsung, Cirrus,
Sharp, Oki, Fujitsu, and Foxconn are all key players in the PSP Go. As expected,
Sony is still providing its own main processor.
- Samsung’s 16GB NAND flash chip essentially replaces the original PSP’s UMD
- The majority of chips are covered by EMI (electromagnetic interference)
shields. We had to remove a total of five shields to access the chips
(thankfully, they were not soldered onto the board). By comparison, the 3rd
Generation iPod touch has only one EMI shield.
- Unfortunately, Sony still uses only an 802.11b chip for wireless internet
connectivity. This perhaps did not matter as much in the past. Now that there’s
no UMD slot, people will have to rely on other means (including Wi-Fi) to get
content onto the PSP Go.
- The battery is user replaceable! All that stands between you is seven screws
and the careful peeling of the Warranty Void sticker. You don’t even need a
soldering iron — the battery has its own connector to the logic board.
- The Warranty Void sticker will only rear its ugly face (show a “VOID VOID”
message) if it’s peeled back more than necessary. Just slide an iPod opening
tool between battery and sticker and work gently side-to-side until the battery
is free from the sticker.
- The PSP Go uses very tricky connectors for its joystick, top buttons,
headphone jack, and Select/Start buttons. Thankfully, you need to disconnect
just the Select/Start buttons from the logic board to get it out of the Go’s
- The sliding mechanism complicates the overall design and increases the
manufacturing cost of the PSP Go. Still, the pricing puts it within $50 of PS3
Slim territory, although the PS3 is not a direct competitor. It will be
interesting to see if this price is a deal breaker for hand-held gamers.
