Product details

Overview

S25FS064SAGNFB033 from Infineon is a 64 Mb (8 MB) serial NOR flash memory with SPI Multi-I/O interface, operating at 1.8 V supply. It supports DDR Quad I/O read up to 80 MBps, features hardware ECC for single-bit error correction, 100,000 program-erase cycles, and 20-year data retention. Used in industrial embedded systems requiring reliable non-volatile storage with XIP capability.

For engineers reviewing the S25FS064SAGNFB033 datasheet, S25FS064SAGNFB033 pinout, S25FS064SAGNFB033 application, or S25FS064SAGNFB033 equivalent, key selection criteria include 1.7–2.0 V operation, hybrid/uniform sector erase options, OTP array size, AEC-Q100 grade support, and QPI mode compatibility with legacy S25FL families.

Technical Context

This device implements Infineon's 65-nm MIRRORBIT™ technology with ECLIPSE architecture, enabling high-density, low-power serial flash operation. It supports both legacy SPI command subsets and extended QPI mode, with configurable 24-/32-bit addressing and SFDP/CFI for runtime configuration discovery.

The logic block includes dedicated control logic for burst wrap, continuous XIP, and multi-I/O data paths with dual-lane latency handling. Internal ECC engine operates transparently during read/write, and erase suspend/resume enables real-time system responsiveness during background operations.

Key Specifications

Memory Density	64 Mb (8 MB) - sufficient for firmware images, boot code, and configuration data in resource-constrained microcontrollers.
Interface	SPI Multi-I/O with QPI mode - enables 4-line parallel transfers and reduced instruction overhead vs standard SPI.
Read Throughput	80 MBps DDR Quad I/O - supports real-time XIP execution of code directly from flash without local RAM buffering.
Erase Granularity	Hybrid sectors: eight 4 KB + one 32 KB at top/bottom, rest 64 KB - balances fine-grained update flexibility with bulk efficiency.
Endurance & Retention	100,000 P/E cycles / 20 years retention - validated for industrial and automotive applications with long field lifetimes.
Voltage Range	1.7 V to 2.0 V - compatible with low-voltage SoC I/O domains and reduces dynamic power consumption.

IO3 (RESET#)	Reset Input / Data Lane 3	Hardware reset trigger; doubles as IO3 in quad/DDR modes; requires external pull-up for normal operation.
VCC	Power Supply	1.7–2.0 V core and I/O supply; decoupling capacitor required per datasheet layout guidelines.
VSS	Ground	Reference return path for all digital and analog circuitry; must be low-impedance connection to PCB ground plane.

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar serial NOR flash applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
S25FL132K0XMFI000	32 Mb density, 3.0 V operation, no DDR support, lower max read rate (40 MBps)	Limited to cost-sensitive, non-automotive designs with simpler timing budgets	Select only if voltage domain is 2.7–3.6 V and DDR/XIP not required.
S25FS256SAGNFI100	256 Mb density, same 1.8 V, DDR Quad I/O, identical pinout and command set	Drop-in upgrade path for higher firmware capacity without redesign	Choose when future firmware growth or dual-application partitioning is anticipated.

Compared with S25FL132K, the S25FS064SAGNFB033 delivers double density, DDR capability, and automotive qualification; versus S25FS256S, it offers lower cost and power for fixed-function devices where 64 Mb suffices.

FAQ

Does S25FS064SAGNFB033 support Quad Peripheral Interface (QPI) mode?

Yes, the device fully supports QPI mode with 4-line command/address/data transfer, reducing instruction overhead and improving throughput over standard SPI. QPI entry/exit is controlled via status register bits, and the command set remains backward-compatible with S25FL1-K/S25FL-P families.

What is the function of the IO3/RESET# pin in normal operation?

In normal SPI operation, IO3 serves as the RESET# input: pulling it low initiates a hardware reset that clears internal state and returns the device to standby. During Quad or DDR transfers, it functions as IO3 data lane. External pull-up is mandatory unless reset functionality is intentionally disabled.

How does the hybrid sector option affect firmware update design?

The hybrid sector layout-eight 4 KB sectors plus one 32 KB sector at either end-enables atomic updates of small boot code sections while preserving larger application partitions. This avoids full-chip erases during minor patches and improves field update reliability in constrained environments.

Is the 1024-byte OTP array accessible after initial programming?

Once programmed, OTP bytes cannot be erased or rewritten. However, read access remains unrestricted, and the array supports byte-wise programming. It is commonly used for cryptographic keys, calibration coefficients, or unique serial numbers that must persist across all device lifecycles.
