Infineon Technologies S25FL512SAGMFV010

Overview

S25FL512SAGMFV010 from Infineon is a 512 Mb (64 MB) serial NOR flash memory with SPI Multi-I/O interface, designed for boot code storage and firmware execution in embedded systems. It supports Quad, Dual, and DDR read modes up to 80 MHz (80 MBps Quad DDR), features 256-KB uniform sectors, 100,000 program-erase cycles, and 20-year data retention. Operates across industrial temperature range (–40°C to +85°C) in 16-pin SOIC package.

For engineers reviewing the S25FL512SAGMFV010 datasheet, S25FL512SAGMFV010 pinout, S25FL512SAGMFV010 application, or S25FL512SAGMFV010 equivalent, key selection criteria include SPI Multi-I/O timing compliance, uniform sector erase granularity, OTP security configuration, and AEC-Q100 Grade 3 qualification for automotive control modules.

Technical Context

This device implements Infineon's 65 nm MIRRORBIT™ technology with Eclipse™ architecture, enabling high-density nonvolatile storage with hardware ECC for single-bit error correction. Its command set is fully compatible with S25FL-A/K/P families, supporting extended 32-bit addressing and CFI/JEDEC SFDP parameter discovery.

The logic block integrates SRAM latches, X/Y decoders, and configurable I/O drivers supporting VIO from 1.65 V to 3.6 V independent of core VCC (2.7–3.6 V). AutoBoot functionality enables automatic Normal or Quad Read at power-up or reset from a preselected address.

FAQ

What is the maximum clock frequency supported in Quad DDR mode?

The S25FL512SAGMFV010 supports Quad DDR read operations at up to 80 MHz, delivering 80 MBps effective throughput. This requires VIO = VCC = 3.0–3.6 V and strict adherence to DDR timing specifications including tDSH, tDHD, and tDQMH as defined in Section 5.5 of the datasheet. No external DLL or phase alignment circuitry is needed.

Does this part support hardware reset via the RESET# pin?

Yes, the RESET# pin provides asynchronous hardware reset functionality. Asserting RESET# low clears internal command state, resets the address counter, and places the device into standby mode. After release, the device enters ready state and accepts new commands after tRES1 (max 100 ns). This pin is not multiplexed and operates independently of CS#.

How is the 1024-byte OTP array accessed and protected?

The OTP array is accessed via dedicated One-Time Program commands (0x4B, 0x42) and resides at fixed address 0x00000000 in the OTP address space. Once programmed, bits cannot be erased. Protection is enforced by status register lock bits (SRWD, TB, BP[2:0]) and requires Write Enable (0x06) before programming. Physical fuse-based write-once behavior is guaranteed by Infineon's process.

Can the device operate with VIO = 1.8 V while VCC = 3.3 V?

Yes, the S25FL512SAGMFV010 supports independent VIO (1.65–3.6 V) and VCC (2.7–3.6 V) supplies. At VIO = 1.8 V and VCC = 3.3 V, it maintains full SPI Multi-I/O functionality including Quad and DDR modes, though maximum clock rates are reduced per the "lower I/O voltage" performance table (e.g., Quad Read limited to 33 MBps at 66 MHz).
