Product details
Overview
S29GL256S11DHIV23 from Infineon is a 256 Mb (32 MB), 16-bit parallel NOR flash memory IC with MIRRORBIT™ Eclipse 65 nm technology, 3.0 V core supply (2.7–3.6 V), 90 ns random access time, and 15 ns page access time. It integrates hardware ECC for single-bit error correction, 128-kB uniform sector erase, and a 512-byte programming buffer - deployed in automotive instrument clusters for firmware storage and boot code execution.
For engineers reviewing the S29GL256S11DHIV23 datasheet, S29GL256S11DHIV23 pinout, S29GL256S11DHIV23 application, or S29GL256S11DHIV23 equivalent, key selection criteria include industrial-plus temperature grade (–40°C to +105°C), Versatile I/O support (1.65 V to VCC), CFI compliance, OTP array security, and suspend/resume capability for real-time system updates.
Technical Context
This device implements an asynchronous parallel interface with word-aligned addressing (A0–A23), supporting both standard and page-mode reads. Its embedded algorithm controller (EAC) manages program/erase operations autonomously, including automatic ECC generation and status reporting via status register, data polling, or RY/BY# pin.
The flash uses uniform 128-kB sectors with advanced sector protection (ASP) enabling volatile/non-volatile lock per sector, plus a dedicated 1024-byte one-time-programmable (OTP) array split into two lockable regions for secure configuration storage and device identification.

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL256S10TFIV20 | Same density and architecture, but 64-ball LAE FBGA (9 mm × 9 mm) package and 100 ns random access | Preferred for space-constrained PCB layouts where TSOP footprint is prohibitive | Select when board area is constrained and thermal profile permits slightly slower access |
| MX29GL256FHT2I-90G | Micron 256 Mb parallel NOR; 90 ns access, but no integrated ECC or OTP array | Requires external error handling and lacks secure key storage capability | Choose only if cost sensitivity outweighs ECC/OTP security requirements |
Compared with S29GL256S11DHIV23, the TSOP-packaged Infineon variant offers superior thermal robustness and built-in ECC/OTP for safety-critical firmware, while alternatives trade those features for smaller footprint or lower unit cost at the expense of system-level error management complexity.

FAQ
Is S29GL256S11DHIV23 pin-compatible with earlier S29GL256P or S29GL256N variants?
No. S29GL256S11DHIV23 uses a 56-pin TSOP package with updated signal timing and command set alignment to the GL-S architecture. It is not mechanically or electrically compatible with legacy P/N series due to differences in RY/BY# behavior, OTP mapping, and ASP register layout.
Does this device support execute-in-place (XIP) operation?
Yes. The S29GL256S11DHIV23 supports true XIP operation with 90 ns random access and page-mode reads, allowing microcontrollers to fetch instructions directly from flash without copying to RAM - verified in Infineon's application note AP32274.
What is the function of the STB pin on this device?
The STB (Strobe) pin is not present on S29GL256S11DHIV23. It appears only on certain FBGA variants (e.g., LAE/LAA packages) for optional address/data multiplexing. The 56-pin TSOP version uses separate A0–A23 and DQ0–DQ15 pins and omits STB entirely.
Can the OTP array be reprogrammed after initial programming?
No. The 1024-byte OTP array is permanently programmable - once a bit is set to '0', it cannot be changed back to '1'. Each of the two lockable regions can be individually secured via dedicated lock bits, preventing further writes after configuration.
