The chip is a Fujitsu MB91302A of the Fujitsu FR60 family of microcontrollers. It is a 32 bit microprocessor running at up to 68 MHz. It has an internal Mask-ROM, likely as a bootstrap, but most of its firmware is located on an external NOR-flash (Fujitsu MB85432BF). The firmware on the external flash is updatable. These updates are automatically performed during normal PSX firmware updates.
