S25FL256LAGNFI013

S25FL256LAGNFI013 is a 256-Mbit Serial NOR flash memory from Spansion/Cypress (S25FL256L family). It provides non-volatile storage for firmware and data in embedded systems, accessible over a serial SPI interface.
Key points
- Capacity: 256 Mbit (32 MB)
- Interface: SPI-compatible; supports fast/read-throughput modes, including Dual/Quad I/O and QPI in some configurations
- Voltage: typically 2.7–3.6 V (low-voltage “L” variant)
- Memory organization: 256-byte page size; sectors/blocks (e.g., 4 KB sectors, larger blocks for erase)
- Operations: read, fast read, page program, sector/block/chip erase; supports protection and security features (block protection, status/registers)
- Performance and power: fast read speeds, standard/low-power modes with deep power-down
- Applications: boot and code storage, firmware updates, data logging
Note: The “AGNFI013” suffix encodes package/temperature/lot information; for exact electrical specs, timing, packaging, and supported SPI modes, consult the official S25FL256L datasheet for this variant.
