Product details
Overview
S29GL256S10FAIV20 from Infineon is a 256 Mb (32 MB) parallel NOR flash memory IC with 16-bit data bus, fabricated on 65 nm MIRRORBIT™ Eclipse process. It operates from a single 2.7–3.6 V supply, delivers 90 ns random access time and 15 ns page access time, and integrates hardware ECC for single-bit error correction. It is used in boot code storage for industrial microcontrollers requiring fast XIP execution and reliable non-volatile program retention.
For engineers reviewing the S29GL256S10FAIV20 datasheet, S29GL256S10FAIV20 pinout, S29GL256S10FAIV20 application, or S29GL256S10FAIV20 equivalent, key selection criteria include its 128 kB uniform sector erase granularity, 512-byte write buffer throughput (1.5 MBps), Versatile I/O support (1.65–VCC), AEC-Q100 Grade 2 qualification (–40°C to +105°C), and OTP array for secure configuration storage.
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 all program/erase operations-including suspend/resume-and enforces automatic ECC during read cycles.
The flash array is organized into uniform 128 kB sectors with advanced sector protection (ASP), enabling independent volatile/non-volatile locking per sector. The integrated 1024-byte OTP array contains two lockable regions for immutable firmware keys or calibration data.

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL256P10TFIV20 | Same density and timing, but uses 64-ball LAE Fortified BGA (9 mm × 9 mm); no TSOP option | Preferred for space-constrained PCBs where footprint reduction outweighs manual soldering complexity | Select when board layout prioritizes miniaturization and automated assembly over hand-soldering feasibility |
| MX29GL256FHT2I-90G | Macronix part; 90 ns access, but lacks hardware ECC and OTP array; requires external error management | Suitable for cost-sensitive consumer applications where ECC is handled in software or omitted | Choose only if system-level ECC is already implemented and AEC-Q100 qualification is not required |
Compared with S29GL256P10TFIV20, this TSOP variant offers easier prototyping and rework; versus MX29GL256FHT2I-90G, it provides built-in ECC and OTP security-critical for automotive and medical use cases where data integrity is non-negotiable.

FAQ
Is S29GL256S10FAIV20 pin-compatible with earlier S29GL256N or S29GL256P variants?
No. While functionally similar, S29GL256S uses a revised command set and timing model optimized for 65 nm MIRRORBIT™ Eclipse. Pinout matches S29GL256P in TSOP package, but differences in reset behavior, OTP access protocol, and ASP register mapping require firmware validation before drop-in replacement.
Does this device support burst read or synchronous interface modes?
No. S29GL256S10FAIV20 is strictly asynchronous and does not support burst, clocked, or DDR read modes. It relies on CE#, OE#, and WE# handshaking for all operations. Page-mode reads (15 ns) are the fastest supported sequential access method.
How is the 1024-byte OTP array accessed and locked?
The OTP array resides at fixed address offset 0x0000_0000 in the CFI query region. Locking is performed via dedicated unlock/lock commands issued to specific addresses in the status register ASO map; each of the two 512-byte regions can be independently locked permanently after programming.
What thermal derating applies above 85°C ambient?
Per datasheet Section 10.4, the device is rated for full performance up to +105°C junction temperature. At 105°C ambient with typical PCB copper pour, junction rise is ~15°C; no derating of access time or endurance is specified, but active current increases ~12% versus 25°C conditions.
