SPI Flash Device Database and Capability Flags.
This file defines the supported Flash devices, their JEDEC IDs, and capability flags (Profiles) used by the driver to handle vendor-specific quirks (Winbond vs Macronix vs ISSI).
Definition in file spiFlash_list.h.
Data Structures | |

| SPI Flash Device Descriptor. More... | |
Macros | |
Addressing & Boot Flags | |
Capabilities related to memory size and startup state. | |
| #define | FLAG_4BYTE_SUPPORT (1 << 0) |
| Supports 4-Byte Addressing Mode. | |
| #define | FLAG_4BYTE_EXIT_ISSI (1 << 1) |
| Quirk: ISSI-Specific 4-Byte Exit. | |
| #define | FLAG_UNLOCK_ON_PROBE (1 << 2) |
| Quirk: Auto-Lock on Power Up. | |
Quad Enable (QE) Method Flags | |
Defines how to enable QSPI mode (Quad I/O). There is no standard JEDEC command to enable Quad mode. Each vendor implements this differently. | |
| #define | FLAG_QE_SR2_BIT1 (1 << 3) |
| Method A: Winbond Style (Status Register 2). | |
| #define | FLAG_QE_SR1_BIT6 (1 << 4) |
| Method B: Macronix/ISSI Style (Status Register 1). | |
Read Mode Capabilities | |
Supported high-speed read commands. | |
| #define | FLAG_DREAD_SUPPORT (1 << 6) |
| Supports Dual Output Read (1-1-2). | |
| #define | FLAG_QREAD_SUPPORT (1 << 7) |
| Supports Quad Output Read (1-1-4). | |
Helper Masks | |
Macros for internal logic simplification. | |
| #define | FLAG_QE_ENABLE_VIA_SR (FLAG_QE_SR2_BIT1 | FLAG_QE_SR1_BIT6) |
| Check if QE requires a Status Register Write. | |
Vendor Profiles | |
| #define | PROFILE_WINBOND_64 (FLAG_DREAD_SUPPORT | FLAG_QREAD_SUPPORT | FLAG_QE_SR2_BIT1) |
| Profile for Winbond <= 64Mb. | |
| #define | PROFILE_WINBOND_128 (FLAG_DREAD_SUPPORT | FLAG_QE_SR2_BIT1) |
| Profile for Winbond 128Mb. | |
| #define | PROFILE_MACRONIX_LARGE |
| Profile for Macronix > 16MB. | |
| #define | PROFILE_ISSI_LARGE |
| Profile for ISSI > 16MB. | |
| #define | PROFILE_GIGA_LARGE (FLAG_QREAD_SUPPORT | FLAG_4BYTE_SUPPORT ) |
| Profile for GigaDevice > 16MB. | |
GigaDevice IDs | |
| #define | JEDEC_ID_GD25LB512MEYIGR 0xC8671A00 |

| #define | JEDEC_ID_W25Q64JWSSIQ 0xEF601700 |
| Winbond 64Mb (Ti60F225). | |
Macronix IDs | |
| #define | JEDEC_ID_MX25U25645GZ4I00 0xC2253900 |
| Macronix 256Mb (Ti180J484). | |
ISSI IDs | |
