404-ball or 364-ball variations depending on the exact SKU.
The AST2500 includes an ECC-enabled SPI flash controller. However, the original documentation was ambiguous. The new revision provides explicit code examples for initializing ECC regions for the boot loader. Failure to follow the "new" sequence results in a 30% chance of boot failure after power cycling due to "Flash Uncorrectable Error" flags.
