Chipsbank CBM2099EA Data Recovery

Zero Alpha provides expert data recovery for USB flash controllers, including the Chipsbank CBM2099EA. Used in many USB drives and embedded storage modules, this chip is a full-feature NAND controller. Damage from power surges, connector breaks, or internal failures can disrupt data access. We offer both local and mail-in recovery services worldwide to salvage your files, even when the drive no longer appears under USB.

Key Features

  • Supports raw NAND flash memory, handling ECC, wear-leveling, and command/address control
  • Exposes a full 8-bit data bus (DQ0–DQ7) plus control signals (CLE, ALE, WE#, RE#, CE#, R/B#)
  • Multiple voltage domains: core logic, I/O interface, and USB bus supply
  • Package options include QSOP-24 and QSOP-28 footprints, used in many flash drives

Common Failure Modes

  • USB connector damage or broken VBUS line, meaning the chip doesn’t get power
  • Controller corruption or firmware table damage inside CBM2099EA causing “no device found”
  • NAND bus line damage: CLE/ALE/WE#/RE# pins lose connection (often under flex or glue)
  • Voltage rail failure (for example, I/O rail not switching between correct levels — 1.8 V vs 3.3 V), leading to unreadable NAND
  • Electrostatic or over-voltage damage to sensitive power pins or core logic (1.2 V domain)

Knowing the pinout of the CBM2099EA is essential for chip-off recovery. Below are mapping tips & safety checks we use:

  • Power domains: Verify via multimeter the voltage on several pins: USB bus (VBUS ~5V), core ~1.2V, I/O ~1.8V or 3.3V depending on board version.
  • Ground (VSS): Multiple ground pins will be found — use continuity to ground plane to confirm.
  • Data & control pins: The NAND data lines (DQ0-DQ7) typically share one side of the chip; control signals (CLE, ALE, WE#, RE#, CE#, R/B#) are usually bunched near them.
  • Voltage mismatch caution: Some CBM2099EA variants use **3.3V for I/O NAND**, others use **1.8V**. Applying wrong voltage kills the NAND permanently.
