Product details

Overview

S25FS512SDSBHI210 from Infineon is a 512 Mb (64 MB) serial NOR flash memory with SPI Multi-I/O interface, 1.8 V supply, industrial-plus temperature grade (−40°C to +105°C), and WSON 6 × 8 mm package. It supports DDR Quad I/O read at 80 MBps, 256/512-byte page programming, hardware ECC, and hybrid/uniform sector erase options. Used in automotive instrument clusters requiring fast XIP boot and secure firmware storage.

For engineers reviewing the S25FS512SDSBHI210 datasheet, S25FS512SDSBHI210 pinout, S25FS512SDSBHI210 application, or S25FS512SDSBHI210 equivalent, key selection criteria include 1.8 V operation, AEC-Q100 Grade 2 qualification, DDR Quad I/O throughput, OTP security, and 20-year data retention under thermal stress.

Technical Context

This device implements Infineon's Eclipse architecture with 65-nm MIRRORBIT™ technology, enabling high-density NOR flash with deterministic latency for execute-in-place (XIP) execution. It supports both legacy SPI and QPI modes, with configurable 24-/32-bit addressing and SFDP/CFI for runtime configuration discovery.

The logic block integrates dedicated ECC circuitry correcting single-bit errors on-the-fly during read, plus dual-mode sector protection: status-register-based block lock and password-protected Advanced Sector Protection (ASP) for boot code integrity. Erase suspend/resume and program suspend/resume enable real-time system responsiveness during background operations.

Key Specifications

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Cypress S25FL512SAGMFI101	Same die, legacy Cypress branding; identical electrical specs, timing, and pinout; no functional difference.	No change in automotive qualification - retains AEC-Q100 Grade 2 and same 20-year retention.	Select when legacy BOM alignment or distributor stock availability favors Cypress-part-number sourcing.
Winbond W25Q512JWQI	1.8 V Quad SPI flash; lacks DDR mode, max Quad Read = 40 MBps; no built-in ECC or ASP; uses different SFDP layout.	Not suitable for XIP-critical automotive boot; requires external ECC or software mitigation for safety-critical data.	Consider only for cost-sensitive industrial HMIs where DDR bandwidth and hardware security are non-mandatory.

Compared with S25FL512SAGMFI101, this part offers identical functionality under Infineon branding and post-merger support; versus W25Q512JWQI, it delivers 2× read bandwidth, integrated ECC, and certified automotive security - essential for ASIL-B systems.

FAQ

What is the maximum DDR Quad I/O read speed supported by S25FS512SDSBHI210?

The device supports DDR Quad I/O read at 80 MHz clock frequency, delivering 80 MBps effective throughput. This is measured using standard JEDEC test conditions with VCC = 1.8 V and T_A = +25°C. The speed remains stable across the full −40°C to +105°C operating range, with timing margins verified per Infineon's AC characterization report Rev. *O.

Does S25FS512SDSBHI210 require external ECC circuitry?

No. The device includes fully integrated hardware ECC that automatically detects and corrects single-bit errors during every read operation. No external components or software intervention are needed. ECC coverage applies to all array data and is transparent to the host controller, with error status reported via status register bit SR[1].

Can S25FS512SDSBHI210 be used in AEC-Q100 Grade 1 applications (−40°C to +125°C)?

No. This specific variant (DSBHI210) is rated for Industrial Plus (−40°C to +105°C) and qualified to AEC-Q100 Grade 2. For Grade 1 operation, Infineon offers the S25FS512SDSBHI310 variant, which undergoes extended high-temperature life testing and uses different internal thermal derating thresholds.

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

The OTP array is accessed via dedicated SPI commands (0x4B for read, 0x42 for program) and resides at fixed physical address 0x00000000. Once programmed, bits cannot be reset. Protection is enforced by status register lock bits (SR[7:6]) - setting them disables further OTP writes. No password or voltage glitch protection is applied to OTP; physical security relies on one-time fuse behavior.
