Product details

Overview

S25FS256SDSBHI300 from Infineon is a 256 Mb (32 MB) serial NOR flash memory IC with SPI Multi-I/O interface, 1.8 V supply, industrial temperature grade (–40°C to +85°C), and BGA-24 6 × 8 mm package (FAB024 footprint). It supports Quad I/O, DDR Quad I/O read up to 80 MBps, 256-byte/512-byte page programming, and hardware ECC for single-bit error correction.

For engineers reviewing the S25FS256SDSBHI300 datasheet, S25FS256SDSBHI300 pinout, S25FS256SDSBHI300 application, or S25FS256SDSBHI300 equivalent, key selection criteria include hybrid/uniform sector erase options (4 KB/64 KB/256 KB), SFDP/CFI configuration support, OTP array size (1024 bytes), AEC-Q100 grade compatibility, and deep power-down current (6 µA).

Technical Context

This device implements Infineon's 65-nm MIRRORBIT™ Eclipse architecture, enabling high-density serial NOR with deterministic latency and XIP-capable continuous read mode. It supports both standard SPI (modes 0/3) and enhanced Multi-I/O protocols including QPI and DDR Quad I/O, with configurable 24-/32-bit addressing.

The flash integrates dual-sector protection schemes: status-register-based block protection and password-controlled Advanced Sector Protection (ASP), plus hardware-managed ECC for program/erase reliability. Erase endurance is rated at ≥100,000 cycles with 20-year data retention under industrial conditions.

Key Specifications

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 S25FS256SAGBHI300	Same die, identical electrical specs and pinout; rebranded part post-Infineon acquisition	No functional difference; same industrial temp grade and FAB024 package	Select when sourcing from legacy Cypress-distributed inventory or cross-referenced design libraries
Winbond W25Q256JWSIQ	256 Mb, 1.8 V, but uses 4-byte addressing only; no DDR mode; lower max read rate (40 MBps)	Lacks DDR Quad I/O and ASP; OTP size is 512 bytes vs. 1024 bytes	Choose for cost-sensitive designs where DDR performance and advanced security are not required

Compared with S25FS256SDSBHI300, the Cypress rebrand offers full equivalence, while the Winbond alternative trades DDR speed and ASP security for lower unit cost and simpler driver integration in non-safety-critical applications.

FAQ

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

The S25FS256SDSBHI300 supports DDR Quad I/O read operations at up to 80 MHz clock frequency, delivering 80 MBps effective throughput. This is specified in the AC characteristics section (Table 6.5) of the datasheet and requires proper impedance-controlled routing and termination matching on the host board.

Does this device support both 24-bit and 32-bit addressing?

Yes, the device supports extended addressing with configurable 24-bit or 32-bit address modes via the configuration register. This allows seamless migration from legacy 16 MB devices to 32 MB capacity without changing host controller address bus width, provided the SPI controller firmware enables extended address mode.

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

The OTP array is accessed using dedicated JEDEC-standard One-Time Program commands (0x4B/0x42) and resides at fixed address 0x00000000 in its own address space. It is permanently locked after first write; subsequent writes return status error. Hardware write protection is enforced independently of status register settings.

Can the device operate in standard SPI mode without enabling Multi-I/O features?

Yes, the device is fully backward-compatible with standard SPI mode 0 and mode 3, supporting normal and fast read, page program, and sector erase using only IO0 and IO1. Multi-I/O modes (Dual/Quad/QPI/DDR) are optional enhancements activated via configuration register bits and do not affect basic SPI functionality.
