Product details
Overview
S29GL256S10DHI020 from Infineon is a 256 Mb (32 MB) parallel NOR flash memory IC with MIRRORBIT™ Eclipse 65 nm technology, 16-bit data bus, and single 2.7–3.6 V supply for read/program/erase. It delivers 90 ns random access time, 15 ns page access time, and integrated hardware ECC for single-bit error correction - deployed in automotive instrument clusters requiring deterministic boot code storage.
For engineers reviewing the S29GL256S10DHI020 datasheet, S29GL256S10DHI020 pinout, S29GL256S10DHI020 application, or S29GL256S10DHI020 equivalent, key selection criteria include sector erase granularity (128 kB), OTP array size (1024 bytes), Versatile I/O voltage range (1.65 V to VCC), AEC-Q100 Grade 2 qualification (–40°C to +105°C), and 100,000 program/erase cycles.
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 autonomous program and erase operations, including suspend/resume capability and status reporting via status register, data polling, or RY/BY# pin.
The internal architecture includes a 512-byte write buffer enabling burst programming up to 256 words per command, and a dedicated 1024-byte one-time-programmable (OTP) array split into two lockable regions for secure configuration storage. ECC logic operates transparently during read cycles without software intervention.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL256S10TFI020 | Same die, 64-ball LAE Fortified BGA (9 mm × 9 mm) package - no TSOP footprint compatibility | Targeted at space-constrained designs where board area is prioritized over manual reworkability | Select when using fine-pitch BGA assembly and thermal cycling exceeds TSOP limits |
| N25Q256A13ESE40F | Quad SPI interface, 3 V supply, no built-in ECC - requires external error handling and serial-to-parallel bridge logic | Used in cost-sensitive IoT gateways where pin count reduction outweighs XIP performance needs | Select only if migrating from parallel to serial architecture and accepting firmware overhead for ECC emulation |
Compared with S29GL256S10DHI020, the TSOP-packaged variant offers superior manufacturability and thermal reliability for automotive under-hood use, while the Quad SPI alternative trades deterministic latency for reduced interconnect complexity - making the TSOP version optimal for XIP-critical, safety-certified systems.

FAQ
Does S29GL256S10DHI020 support execute-in-place (XIP) operation?
Yes. The device supports true XIP operation with 90 ns random access time and 15 ns page-mode read, allowing microcontrollers to fetch instructions directly from flash without copying to RAM. Its asynchronous interface and word-aligned addressing ensure deterministic timing for real-time code execution without wait states.
What is the function of the Versatile I/O (VIO) supply pin?
VIO sets the input/output voltage level independently from VCC, ranging from 1.65 V to VCC. This enables direct interfacing with 1.8 V, 2.5 V, or 3.3 V host processors without external level shifters, while maintaining full 2.7–3.6 V core operation for reliable program/erase functionality.
How does the 512-byte write buffer improve programming efficiency?
The buffer accepts up to 512 bytes (256 words) in a single command sequence, reducing overhead from repeated command latching. At 1.5 MBps effective rate, it cuts typical 32 kB firmware sector programming time from ~210 ms (single-word) to ~22 ms - accelerating field updates and manufacturing programming.
Is the OTP array truly one-time programmable?
Yes. The 1024-byte OTP region consists of two 512-byte lockable sections. Once locked (via dedicated command), bits cannot be altered or erased. This ensures permanent storage of cryptographic keys, calibration constants, or device identifiers - meeting IEC 62443 and ISO 21434 security requirements.
