VS1001 Version Changes
This chapter describes changes between different generations of VS1001.
Note: VS1001k is the final, production version of VS1001.
10.1
Changes Between VS1001h and Production Version VS1001k, 2001-08
When the chip is reset with pin XRESET, XTALO and XTALI are driven to ground.
Running with normal clock earlier required slightly different clock generation than for clock-
doubled (see Chapters 4 and 5). This is no longer the case.
Lots of new SCI register MODE bits: SM DIFF, SM FFWD, SM BASS. For details, see Chap-
ter 7.5.1.
Default is now to only decode MP3.
20..60 mV DAC offset corrected.
A firmware bug made it impossible to decode 320 kbits/s MP3 data. This has been corrected.
A hardware bug made it practically impossible to load code to RAM. This has been corrected.
10.2
Changes Between VS1001g and VS1001h, 2001-05
Analog voltage requirements have been lowered. Now full gain can be achieved with a 2.7 V
analog input voltage, whereas 3.4 V was needed before.
10.3
Changes Between VS1001d to VS1001g, 2001-03
Clock is now adjustable, in VS1001d only 24.576 MHz could be used.
Clock doubler added.
VS1001d played 48 kHz instead of 12 or 24 kHz, this is corrected.
Version 4.11,
