Sony NW/NWZ series

See also SonyNWAnalysis.


This is the page for the Sony NW and NWZ mp3 player series. It is also known as the Walkman series. A number of these players run a modified version of linux and as a consequence, the code source is available on sony's website. It appears that a number of them use the NEC MP201 and some us the STMP3780/iMX233. This page gives an overview of what is known about them.

The NW and NWZ series are split into several subcategories: the X/E/A/S/Z series. Sony usually releases three or more players at one based on the same hardware but without little differences like the bluetooth or the amount of flash. As a consequence, there a families of players based on the same hardware within each A/E/S/Z series and sometimes even accros series. For example the NW-E060/NW-S760/NW-A860/NWZ-S760/NWZ-A860 series all share the same hardware and the NWZ-A864/5/7 are in the NWZ-A860 family.


The codename is a rockbox designation only. The following table summarizes the SoC used. All entries in red are unsure. All USB PIDs are 0x54c (Sony Corporation).
