: Single 8051-compatible core with embedded MaskROM and RAM.
The (also known as the PS2307 ) is a high-performance USB 3.0-to-Flash micro-controller commonly found in popular flash drives like those from Kingston and Silicon Power. This chip is notorious among hardware enthusiasts and data recovery specialists because it lacks standard debugging interfaces like JTAG or UART, often making it a "black box" when it fails.
This guide explains the technical specifications of the PS2251-07/PS2307 and provides a roadmap for repairing drives that have become "write-protected" or are stuck in a firmware "panic" mode, identifying themselves only as "2307 PRAM". Technical Specifications
