The PCF50606 is the Power Management Unit used in GTA01. Apparently this unit is very popular in MP3 players, as the Rockbox project has talked a lot about writing a driver for it (but hasn't completed any, as far as we know).

Configuration of this PMU is done via an I2C bus from the S3C2410.

  • Connected to: Samsung S3C2410 via I2C, client address is 0x08.
  • The PMU also connects to EINT16 and thus can issue interrupts to the main CPU.

This chip is only used in the Neo1973. The Neo FreeRunner uses NXP PCF50633.
