Product details
Overview
S29GL256S10FHB020 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-used in boot code storage and firmware execution in industrial control systems.
For engineers reviewing the S29GL256S10FHB020 datasheet, S29GL256S10FHB020 pinout, S29GL256S10FHB020 application, or S29GL256S10FHB020 equivalent, key selection criteria include its 128 kB uniform sector erase granularity, 512-byte write buffer, Versatile I/O (1.65–VCC), OTP array, and AEC-Q100 Grade 2 qualification.
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 suspend/resume capability and status reporting via status register, data polling, or RY/BY# pin.
The flash uses a 65 nm MIRRORBIT™ Eclipse cell architecture enabling high density and reliability. It features dual-voltage I/O (VIO = 1.65–VCC), internal hardware ECC, and advanced sector protection with volatile/non-volatile lock options per 128 kB sector.
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 |
|---|---|---|---|
| S29GL256P10TFB020 | Same density and timing, but uses 64-ball LAE FBGA (9 mm × 9 mm); no TSOP option | Preferred for space-constrained PCBs where footprint reduction outweighs manual rework feasibility | Select when board layout prioritizes BGA miniaturization and automated assembly over field serviceability |
| MX29GL256FHT2I-90G | Macronix part; 90 ns access, but lacks integrated ECC and OTP array; requires external error handling | Suitable for cost-sensitive consumer applications where firmware integrity is managed in software | Choose only if ECC and OTP are handled externally and AEC-Q100 qualification is not required |
Compared with S29GL256P10TFB020, this TSOP variant offers easier prototyping and rework; versus MX29GL256FHT2I-90G, it provides hardware ECC and automotive qualification at higher unit cost but lower system-level validation effort.

FAQ
What is the maximum operating temperature range for S29GL256S10FHB020?
This part is qualified to AEC-Q100 Grade 2, supporting continuous operation from –40°C to +105°C. The datasheet specifies full electrical performance across this range, including 90 ns random access time and 100,000 program/erase cycles at maximum temperature. Thermal derating is not required up to +105°C ambient.
Does S29GL256S10FHB020 require an external VPP voltage for programming?
No. It uses a single 2.7–3.6 V VCC supply for all operations-read, program, and erase-eliminating the need for external high-voltage generators or charge pumps. Internal voltage regulation and pump circuits generate required programming/erase voltages, simplifying power design and reducing BOM count.
How is the 1024-byte OTP array structured and protected?
The OTP array consists of 64 words (1024 bytes) divided into two 512-byte lockable regions. Each region has an independent non-volatile lock bit; once set, the corresponding region becomes permanently read-only. Locking is irreversible and performed via dedicated CFI commands, providing tamper-resistant storage for cryptographic keys or calibration data.
Can S29GL256S10FHB020 be used in a 1.8 V I/O system?
Yes. Its Versatile I/O feature supports VIO from 1.65 V to VCC, so with VCC = 3.0 V, VIO can be set to 1.8 V. This allows direct interfacing with 1.8 V microcontrollers or FPGAs without level shifters, while maintaining full 90 ns access timing and all embedded functions including ECC and sector protection.
