S25FS512SAGNFI013

Introduction to S25FS512SAGNFI013
- It is a 512-Mbit serial NOR flash memory from Cypress (Spansion lineage) in the S25 family.
- Purpose: firmware/code storage and data storage for embedded systems; suitable for boot memory and firmware updates.
- Interface: SPI-based with support for higher-throughput modes such as dual/quad I/O SPI (depending on configuration).
- Operations: standard SPI commands plus page program, sector/block erase, and security features (status/lock protections) with deep power-down.
- Electrical/variants: typically 2.7–3.6 V supply; the “013” suffix denotes a specific revision/grade; packaging options vary by market.
Note: exact timings, voltage ranges, and package options should be verified in the latest datasheet for this specific revision.

Equivalent 512Mb SPI NOR flash parts (vendor-agnostic):
- Winbond W25Q512JV/W25Q512JVEQ
- Macronix MX25L512E/MX25L512U
- GigaDevice GD25Q512E/U
- ISSI IS25LP512D

- Micron N25Q512A
Note: verify package, voltage, timing and peculiar protections match your design.

Here are the key features of S25FS512SAGNFI013 (Serial NOR Flash):
- Density: 512 Mb (64 MB) serial NOR flash
- Interface: supports standard SPI, Dual I/O, Quad I/O, and QPI
- Addressing: 3-byte addressing (no 4-byte mode needed for this density)
- Memory organization: 256-byte pages; erase: 4 KB sectors; 32 KB/64 KB blocks; chip erase option
- Read/IO modes: multiple read options including Fast Read and Quad/Quad I/O Read
- Security/protection: software and hardware write protection; block/sector protection (BP) and status register protections
- Power modes: deep power-down and low-power idle modes
- Endurance/retention: typical program/erase endurance in the 100k+ cycles range with long data retention (years)
- Operating voltage: VCC in the common serial flash range (I/O pins included) with compatible supply range
- Temperature: industrial-grade operating range (and variants available for extended temps)
- Package: 8-pin surface-mount package (typical for this density)
Note: Always verify exact voltage, temperature, and timing in the latest datasheet for this exact part variant.

Pin count: 8 pins (8-pin package, e.g., SOIC).
Function: 512-Mbit serial SPI flash memory (S25FS512S). Typical pinout (example):
- 1 CS# (Chip Select)
- 2 DO# / MISO (Data out)
- 3 DI / MOSI (Data in)
- 4 GND
- 5 SCK (Serial Clock)
- 6 WP# (Write Protect)
- 7 HOLD# (Hold)
- 8 VCC
Notes: Uses a standard SPI interface (and supports wiring for write protection and hold). GND and VCC power the device.
