Description3.3V Uniform Sector Dual and Quad Serial Flash
Datasheet SummaryAI
1. Overview & Functionality

️· Device Type: Uniform Sector Flash Memory
️· Quad Mode: Supports quad operation via the QE bit.

2. Key Features

️· Status Register Protection (SRP): Offers different methods of protecting the status register:
- Software Protection (Default): Writeable after a Write Enable command.
- Hardware Protection: Locked when WP# (Write Protect) is low.
- Hardware Unprotected: Writeable when WP# is high.
- Power Supply Lock-Down: Requires power cycle to unlock.
- One-Time Programmable (OTP): Permanently locked. (Special order)
️· Block Protection (BP4-BP0): Define protected memory areas against Program/Erase commands. Their behavior is dependent on the CMP bit.
️· CMP Bit: Used in conjunction with the BP bits to control protection behavior.
️· QE Bit: Enables Quad mode and controls the state of WP# and HOLD# pins. Default is 0.
️· LB Bit (OTP): Locks the Security Registers. Once set, they are read-only.
️· HPF Bit: Indicates High Performance Mode status.
️· SUS Bit: Indicates if an Erase/Program Suspend command has been executed.
️· WIP Bit: Indicates if the device is busy performing a program, erase, or write status register operation.
️· WEL Bit: Indicates the status of the internal Write Enable Latch.

3. Status Register Details

Bit Name Description
S15 SUS Erase/Program Suspend status
S14 CMP CMP bit. Affects block protection behavior.
S13 HPF High Performance Flag. Indicates High Performance Mode.
S12 Reserved Reserved bit.
S11 Reserved Reserved bit.
S10 LB One-Time Programmable lock for Security Registers.
S9 QE Quad Enable. Controls Quad mode and WP#/HOLD# pins.
S8 SRP1 Status Register Protection Bit 1.
S7 SRP0 Status Register Protection Bit 0.
S6 BP4 Block Protect bit 4.
S5 BP3 Block Protect bit 3.
S4 BP2 Block Protect bit 2.
S3 BP1 Block Protect bit 1.
S2 BP0 Block Protect bit 0.

S0 WIP Write In Progress.



4. Important Considerations & Notes:

️· Special Order Features: One-Time Programmable (OTP) protection and Power Supply Lock-Down features are available on special order.
️· CMP Bit Dependency: Block protection behavior heavily relies on the CMP bit settings. Refer to the datasheet for the detailed interaction between CMP and BP bits.
️· Security Registers: The Security Registers are protected by the LB bit.

    Hello, Please ask a question about GD25Q80CSIG Datasheet.
    Example questions: ➤ What happens when the 'wip' bit in the status register is set to '1'?➤ What are the two primary functions of the 'qe' (quad enable) bit, and what is recommended regarding its setting if the wp# or hold# pin is directly connected to power or ground?➤ Explain the function of the 'cmp' bit and how it interacts with the 'bp4-bp0' bits for memory protection.
