Product details
Overview
S25FS064SAGBHN020 from Infineon Technologies is a 64 Mb (8 MB) serial NOR flash memory IC with SPI Multi-I/O interface, 1.8 V single supply operation, DDR support, and hybrid/uniform sector erase architecture. It delivers up to 80 MBps read throughput via DDR Quad I/O, supports SFDP/CFI for auto-configuration, and integrates hardware ECC for single-bit error correction-used in industrial microcontroller boot code storage and firmware update partitions.
For engineers reviewing the S25FS064SAGBHN020 datasheet, S25FS064SAGBHN020 pinout, S25FS064SAGBHN020 application, or S25FS064SAGBHN020 equivalent, key selection criteria include 1.7–2.0 V VCC tolerance, AEC-Q100 Grade 2 qualification (–40°C to +105°C), BGA-24 6 × 8 mm package with 5 × 5 ball layout, and support for QPI mode and erase suspend/resume functionality.
Technical Context
This device implements Infineon's 65-nm MIRRORBIT™ technology with ECLIPSE architecture, enabling high-density, low-power NOR flash operation. Its SPI-MIO interface supports all standard clock modes (0 and 3), dual/quad I/O, DDR, and QPI protocols-allowing flexible host controller integration without protocol translation logic.
The internal control logic manages hybrid sector erase (eight 4 KB + one 32 KB sectors at top/bottom) and uniform 64 KB/256 KB block erase options. Hardware ECC operates transparently during program/erase cycles, and SFDP v1.6 compliance enables runtime configuration discovery by host firmware.

IC Role / Device Role / Timing Role: Secure, long-retention configuration store with password-protected sector access for HIPAA-compliant data integrity. Use Value: 1024-byte OTP stores cryptographic keys; SFDP enables automatic parameter discovery across product variants-reducing BOM management effort. | Use Scenario: Storing protocol stacks (DLMS/COSEM, IEC 61850), encryption certificates, and firmware images in AMI gateways deployed in outdoor substations. IC Role / Device Role / Timing Role: High-reliability firmware repository operating continuously at –40°C to +105°C with deep power-down current of 6 µA. Use Value: Uniform 256 KB erase blocks ensure compatibility with field-upgrade toolchains; standby current <25 µA extends battery backup runtime during grid outages. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Cypress S25FL132K0XMFI010 | 32 Mb density, no DDR support, 1.8 V only, SOIC-8 package | Limited to smaller firmware images; lacks DDR bandwidth and BGA packaging for high-pin-count SoCs | Select when cost-sensitive designs require basic SPI NOR without DDR or advanced security |
| Winbond W25Q64JWBIQ | 64 Mb, 1.8 V, DTR support, but no ASP or OTP; 8-pin WSON package | Missing password-based sector protection and dedicated key storage-requires external security co-processor | Choose for consumer IoT where AEC-Q100 and hardware security are non-mandatory |
Compared with S25FL132K0XMFI010 and W25Q64JWBIQ, the S25FS064SAGBHN020 uniquely combines DDR Quad I/O bandwidth, AEC-Q100 Grade 2 qualification, ASP, and OTP in a BGA-24 package-making it optimal for safety-critical, high-bandwidth embedded boot applications.

FAQ
What is the maximum clock frequency supported in DDR mode?
The S25FS064SAGBHN020 supports DDR Quad I/O operation up to 80 MHz, delivering 80 MBps effective read bandwidth. This is confirmed in Table 1 of the official Infineon datasheet (002-03631 Rev. *I), where DDR Quad I/O Read is specified at 80 MHz with 80 MBps throughput. The device does not support DDR operation above this frequency.
Does this part support both 24-bit and 32-bit addressing?
Yes, the S25FS064SAGBHN020 supports extended addressing with configurable 24-bit or 32-bit address modes. This is explicitly stated in the "Features" section of the datasheet and enabled via status register bits. The 32-bit mode is required to access the full 64 Mb address space beyond the 16 MB limit of 24-bit addressing.
Is hardware reset (RESET#) required for initialization after power-up?
No, hardware reset via the RESET# pin is optional. The device performs an automatic power-on reset (cold reset) when VCC rises above the threshold. However, asserting RESET# is recommended before switching between SPI and QPI modes or recovering from unknown interface states, as defined in Section 4.3.3 and 4.3.4 of the datasheet.
Can the OTP array be programmed multiple times?
No, the 1024-byte OTP (One-Time Programmable) array can be programmed only once per byte. Once a bit is set from '1' to '0', it cannot be reverted. Programming is performed using the Write Enable and Program OTP commands, and verification must be done post-programming since no erase function exists for OTP memory.
