Product details
Overview
S29GL256S11FHIV23 from Infineon is a 256 Mb (32 MB) parallel NOR flash memory IC with 3.0 V core supply, 16-bit data bus, and MIRRORBIT™ Eclipse 65 nm technology. It delivers 90 ns random access time, 15 ns page access time, and integrated hardware ECC for single-bit error correction. Designed for embedded boot code storage in industrial control systems requiring high reliability and fast XIP execution.
For engineers reviewing the S29GL256S11FHIV23 datasheet, S29GL256S11FHIV23 pinout, S29GL256S11FHIV23 application, or S29GL256S11FHIV23 equivalent, this device supports asynchronous read, sector erase, suspend/resume operations, OTP array, CFI compliance, and versatile I/O (1.65 V to VCC) - critical for legacy parallel interface migration and long-lifecycle industrial designs.
Technical Context
This NOR flash implements an asynchronous parallel interface with word-aligned addressing (A0–A23), 32-byte page reads, and 512-byte write buffer programming. Its embedded algorithm controller handles autonomous program/erase with status register, data polling, and RY/BY# signaling.
The device integrates hardware-based ECC for single-bit correction and detects multi-bit errors, supports uniform 128 kB sector erase, and provides advanced sector protection via volatile/non-volatile lock bits plus a dedicated 1024-byte OTP array with two lockable regions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL256P11TFIV20 | Same density and core voltage, but uses 64-ball LAE Fortified BGA (9 mm × 9 mm); no TSOP option | Targeted at space-constrained PCBs where board area is prioritized over socketability or rework ease | Select when footprint reduction and automated assembly outweigh manual debug/test accessibility |
| MX29GL256FHT2I-90G | Micron equivalent with 90 ns access, but lacks hardware ECC and OTP array; requires external error handling | Suitable for cost-sensitive applications where firmware corruption risk is mitigated by host-level redundancy | Choose only if ECC and OTP features are not required and BOM cost is primary constraint |
Compared with S29GL256P11TFIV20, the S29GL256S11FHIV23 offers superior serviceability via TSOP packaging and identical electrical performance; versus MX29GL256FHT2I-90G, it delivers built-in reliability features that reduce system-level validation effort and improve field failure MTBF.

FAQ
Is S29GL256S11FHIV23 compatible with legacy S29GL256N devices?
No. The S29GL256S11FHIV23 uses updated command sets, enhanced ECC architecture, and revised timing parameters compared to the N-series. While pinout is identical in TSOP, firmware drivers must be updated to support new status register layout and suspend/resume behavior per datasheet section 5.5.
What is the function of the STB pin on S29GL256S11FHIV23?
The STB (Strobe) pin is not present on the S29GL256S11FHIV23. This pin exists only on certain BGA variants (e.g., LAE package) for synchronous burst mode support. The TSOP version (FHIV23) omits STB and operates exclusively in asynchronous mode per datasheet Figure 1 and Section 8.1.
Does S29GL256S11FHIV23 support Common Flash Interface (CFI)?
Yes. It implements a full CFI parameter table accessible via standard query commands (0x98 at address 0x55). The CFI data includes vendor ID, device geometry, timing parameters, and command set identification - enabling OS-level flash abstraction layers like MTD in Linux to auto-detect and configure the device.
Can VIO be operated at 1.8 V while VCC is at 3.0 V?
Yes. The versatile I/O feature explicitly supports VIO from 1.65 V to VCC. At VCC = 3.0 V, VIO may be independently set to 1.8 V, allowing direct connection to 1.8 V microcontroller buses without level translation, provided all timing specifications in Table 11.4 are met under those voltage conditions.
