are subject to change without notice. Patch codes and new codecs can be automatically loaded from SPI EEPROM at startup. One interesting application is a single-chip standalone player. The instruction RAM of 1280 words (5 kilobytes) is used for MMC communication routines, read-only handling of the FAT and FAT32 filesystems and a 16- or 32-button user interface.● No microcontroller is required, boots from SPI EEPROM (25LC640).
