Product details

Overview

S25FS064SAGBHM023 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, hybrid/uniform sector erase options, and AEC-Q100 Grade 2 automotive qualification (–40°C to +105°C). Used in automotive ADAS boot code storage and industrial firmware update modules.

For engineers reviewing the S25FS064SAGBHM023 datasheet, S25FS064SAGBHM023 pinout, S25FS064SAGBHM023 application, or S25FS064SAGBHM023 equivalent, key selection criteria include DDR Quad I/O throughput, 100,000 program-erase cycles, OTP array size, SFDP/CFI support, and BGA-24 6×8 mm package compatibility with legacy S25FL-S footprint.

Technical Context

This device implements Infineon's 65-nm MIRRORBIT™ technology with ECLIPSE architecture, enabling high-density, low-voltage operation. It supports both legacy SPI and QPI modes, with configurable 24-/32-bit addressing and burst wrap/continuous XIP read modes.

The internal control logic integrates dedicated ECC generation, program/erase suspend-resume capability, and dual protection schemes: status-register-based block protection plus Advanced Sector Protection (ASP) with password-controlled access and boot-code-triggered individual sector locking.

FAQ

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

The S25FS064SAGBHM023 supports DDR Quad I/O operation at up to 80 MHz, delivering 80 MBps effective read throughput. This is confirmed in Table 1 of the official Infineon datasheet (002-03631 Rev. *I), and requires proper PCB layout with matched trace lengths and controlled impedance for all four I/O lines and SCK.

Does this part support hardware reset via the IO3/RESET# pin?

Yes - the IO3/RESET# pin serves as a dedicated hardware reset input. When asserted low, it initiates a warm reset that clears internal state and returns the device to standby mode without cycling VCC. This functionality is electrically and functionally distinct from the power-on reset sequence and is fully documented in Section 3.10 and 5.3.2 of the datasheet.

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

The OTP array is accessed via standard SPI commands (Read/Program) at fixed address range 0x00000000–0x000003FF. Once programmed, bits cannot be reset; protection is enforced by status register lock bits and optional ASP password. Programming requires VPP voltage (if enabled) and passes hardware verification - details are specified in Section 7.3 of the datasheet.

Can this device operate in continuous XIP (execute-in-place) mode?

Yes - the device supports Continuous Read mode with wrap-around addressing, enabling true XIP execution from flash. This mode is activated via specific command sequences and requires host controller support for dummy cycles and latency management. Performance and timing constraints for XIP are defined in Section 4.3.6 and Table 5–10 of the datasheet.
