Product details
Overview
S29GL256S10DHV020 from Infineon is a 256 Mb (32 MB), 16-bit parallel NOR flash memory using 65 nm MIRRORBIT™ Eclipse technology, with 90 ns random access time, 15 ns page access time, and single 3.0 V supply (2.7–3.6 V) for read/program/erase - deployed in industrial-grade embedded boot code storage and firmware update applications.
For engineers reviewing the S29GL256S10DHV020 datasheet, S29GL256S10DHV020 pinout, S29GL256S10DHV020 application, or S29GL256S10DHV020 equivalent, key selection criteria include uniform 128-kbyte sector erase, hardware ECC (single-bit correction), 100,000 program/erase cycles, Versatile I/O (1.65–3.6 V), and CFI-compliant interface for BIOS/firmware compatibility.
Technical Context
This device implements an asynchronous parallel interface with ×16 data bus, word-aligned addressing, and 32-byte page-mode reads. Its embedded algorithm controller (EAC) manages autonomous program/erase operations, status monitoring via RY/BY#, and automatic ECC on read/write paths.
The architecture supports suspend/resume during programming or erasing, advanced sector protection (volatile/non-volatile), and a dedicated 1024-byte OTP array with dual lockable regions - enabling secure boot configuration and calibration data storage in automotive and industrial control systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory density | 256 Mb (32 MB), organized as 2,097,152 × 16-bit words - sufficient for full firmware images in microcontroller-based edge nodes. |
| Access time (random) | 90 ns at VCC = VIO - enables direct XIP execution without external cache in real-time control firmware. |
| Page access time | 15 ns - accelerates sequential instruction fetch within 32-byte aligned pages during boot or ISR execution. |
| Programming buffer | 512 bytes (256 words) - reduces effective programming time by batching writes, critical for field firmware updates. |
| Erase granularity | Uniform 128-kbyte sectors - allows selective firmware partitioning (e.g., bootloader vs. application) with deterministic erase timing. |
| Endurance & retention | 100,000 program/erase cycles; 20-year data retention - meets long-life requirements for industrial PLCs and automotive ECUs. |
| Operating temperature | –40°C to +85°C (Industrial grade) - qualified for deployment in uncontrolled ambient environments like factory-floor HMIs. |
Pinout & Package
Package: 56-pin TSOP (Type I, 400 mil width), JEDEC standard footprint compatible with legacy flash socket designs and automated PCB assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A22 | Address inputs | 23-bit word address bus (AMAX = A23); supports full 256 Mb addressing with no bank switching required. |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus; operates at VIO (1.65–3.6 V), enabling direct interfacing with 1.8 V or 3.3 V controllers. |
| CE# | Chip enable | Active-low chip select; tCE = 90 ns - defines minimum assertion time before valid read data appears. |
| OE# | Output enable | Active-low output control; tOE = 25 ns - determines maximum delay from OE# assertion to valid DQ output. |
| WE# | Write enable | Active-low write strobe; controls latching of command sequences and data into internal registers. |
| RY/BY# | Ready/Busy indicator | Open-drain output; low during embedded operations (program/erase), used for polling-based status detection. |
| RESET# | Hardware reset | Active-low asynchronous reset; forces device into known state, clears status register, aborts ongoing operations. |
| VCC | Core supply | 3.0 V ±10% (2.7–3.6 V); powers core logic, EAC, and voltage generators - no separate VPP required. |
| VIO | I/O supply | Independent 1.65–3.6 V rail; decouples I/O signaling from core voltage, simplifying mixed-voltage system design. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware ECC | On-the-fly single-bit error correction with automatic detection - eliminates need for software-level CRC overhead in safety-critical firmware storage. |
| Versatile I/O | Independent VIO rail (1.65–3.6 V) - permits direct connection to 1.8 V FPGA I/O banks or 3.3 V MCU buses without level shifters. |
| Page-mode read | 32-byte aligned page access with 15 ns cycle time - improves instruction throughput during linear code execution from flash. |
| OTP array | 1024-byte one-time-programmable region with two lockable sectors - stores immutable keys, calibration constants, or device-unique identifiers. |
| CFI compliance | Standard Common Flash Interface parameter table - enables auto-detection and driver compatibility across BIOS, U-Boot, and RTOS flash abstractions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL256P10TFV020 | Same density and timing, but 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 socket-based serviceability. | Select when PCB layout requires BGA miniaturization and reflow-only assembly is acceptable. |
| MX29GL256FHT2I-90G | Macronix part with 90 ns access, but lacks hardware ECC and OTP array; CFI support limited to basic query mode. | Suitable for cost-sensitive consumer applications where ECC and secure storage are not mandated. | Choose only if firmware integrity is managed externally and long-term data retention is not mission-critical. |
Compared with S29GL256P10TFV020, this TSOP variant offers field-serviceable replacement and legacy board compatibility; versus MX29GL256FHT2I-90G, it delivers hardware-level ECC and OTP security essential for industrial and automotive use cases.

FAQ
Does S29GL256S10DHV020 support execute-in-place (XIP) operation?
Yes. The device supports true XIP with 90 ns random access time and 15 ns page-mode reads, enabling direct CPU instruction fetch from flash without copying to RAM. Its architecture includes dedicated address/data latches and fast state control logic optimized for zero-wait-state execution in Cortex-M and Power Architecture microcontrollers.
What is the function of the Versatile I/O (VIO) feature?
VIO provides independent voltage control for the DQ[15:0] bus (1.65–3.6 V), decoupled from the 3.0 V core supply. This allows direct interfacing with 1.8 V FPGAs or 3.3 V MCUs without external level shifters, reducing BOM count and signal integrity risk in mixed-voltage embedded systems.
How does the hardware ECC operate during read cycles?
Hardware ECC runs transparently on every read: the device checks each 512-byte sector for single-bit errors and corrects them in real time before presenting data on DQ[15:0]. No software intervention is needed, and corrected data is latched with no timing penalty - critical for deterministic boot sequences.
Can the OTP array be reprogrammed after initial programming?
No. The 1024-byte OTP array is permanently programmable once per sector; each of its two lockable regions can be individually locked via dedicated command sequence. After locking, further writes to that region are blocked at the hardware level - ensuring permanent storage of cryptographic keys or calibration data.
