Key Information & Summary Points:
️· Device: GD25S513MD (likely a flash memory chip, possibly a SPI NOR flash)
️· Memory Capacity: Not explicitly stated, but implied to be in the range of 32MB (based on protection area descriptions).
️· Interface: Supports Standard SPI, Dual SPI, Quad SPI, and DTR Quad SPI.
️· Data Protection:
- Write Enable (WREN) command enables writing.
- Software Protection: Block Protect (BP3, BP2, BP1, BP0) and Top Bottom (TB) bits control protected areas. Tables show various block ranges that can be protected.
- Deep Power-Down Mode disables all commands except Release and Software Reset.
️· ECC (Error Correction Code): Provides single-error correction (SEC) and double-error detection (DED). ECS# pin indicates ECC events.
️· QE Bit: QE bit is set to 1 and cannot be changed.
Concise Summary:
The GD25S513MD is a flash memory device supporting various SPI interfaces (Standard, Dual, Quad, and DTR Quad). It offers multiple data protection mechanisms including write enable control, software-defined block protection, and a deep power-down mode. ECC functionality provides data integrity with SEC and DED capabilities, indicated by the ECS# pin. The QE bit is fixed at 1. Its memory capacity appears to be around 32MB.
