Product details
Overview
S29GL256P90FACR20 from Cypress Semiconductor is a 256 Mbit (32 MB), 3.0 V-only Page Flash memory IC fabricated on 90 nm MirrorBit process technology, featuring 25 ns page access time, 90 ns random access time, uniform 64 Kword sectors (256 total), and 100,000 erase cycles per sector - deployed in industrial embedded systems for firmware storage and boot code execution.
For engineers reviewing the S29GL256P90FACR20 datasheet, S29GL256P90FACR20 pinout, S29GL256P90FACR20 application, or S29GL256P90FACR20 equivalent, key selection considerations include VersatileI/O™ voltage flexibility (VIO = 1.65–VCC), secured silicon sector with factory-programmable 128-word serial number, CFI compliance, and dual-package availability (64-ball Fortified BGA / 56-pin TSOP).
Technical Context
This device operates as a non-volatile NOR flash memory with synchronous-compatible command-set architecture, supporting byte/word configuration via BYTE# input and hardware reset (RESET#) for system-level recovery. It implements embedded algorithms for program/erase with suspend/resume capability and status reporting via RY/BY# output.
The 90 nm MirrorBit cell structure enables single-supply 3.0 V operation across read/program/erase (2.7–3.6 V), while VersatileI/O™ decouples I/O voltage (VIO) from core supply (VCC), allowing interface compatibility with 1.8 V, 2.5 V, or 3.3 V controllers without level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 256 Mbit (32 MB), organized as 256 uniform 64 Kword (128 KB) sectors |
| Access Time | 90 ns random access (VCC = 3.0–3.6 V); 25 ns page access enables burst reads of 8 words |
| Write Buffer | 32-word (64-byte) buffer reduces multi-word programming time to 13.5 µs/word with VHH acceleration |
| Erase Endurance | 100,000 program/erase cycles per sector - validated for long-life firmware update partitions |
| Data Retention | 20 years at +85°C - meets industrial embedded lifecycle requirements without refresh |
| Supply Range | VCC = 2.7–3.6 V; VIO = 1.65–VCC - supports mixed-voltage SoC interfacing |
| Operating Temp | –40°C to +85°C (Industrial grade), confirmed by temperature-range suffix 'I' in part number |
Pinout & Package
Package: 64-ball Fortified Ball Grid Array (LAA064), 11 × 13 mm, 1.0 mm pitch, Pb-free (RoHS-compliant), marked per ordering convention omitting "S29" prefix and packing type.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A23–A0 | Address Inputs | 24-bit address bus (A23–A0) selects 16 MB word-addressable space; A-1 multiplexed on DQ15 in byte mode |
| DQ15–DQ0 | Data I/O | 16-bit bidirectional data bus; DQ15/A-1 serves as LSB address in byte mode (BYTE# = VIL) |
| CE#, OE#, WE# | Control Inputs | Standard NOR flash control signals; CE# enables chip, OE# gates output, WE# initiates write/erase |
| RY/BY# | Status Output | Active-low open-drain signal: low = active program/erase; high-Z = ready - enables polling-free operation |
| WP#/ACC | Protection/Accel | VIL = protects top/bottom sector; VHH = enables unlock bypass mode for accelerated programming during production |
| RESET# | Hardware Reset | Asynchronous active-low reset that terminates ongoing operations and returns device to read mode |
| VIO | I/O Supply | Separate I/O voltage rail (1.65–VCC) sets logic thresholds for all address/data/control pins - eliminates external level shifters |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory- or customer-lockable region with unique 8-word electronic serial number for secure device identification |
| Advanced Sector Protection | Persistent lock bits + password method allow selective, irreversible sector locking - prevents accidental firmware overwrite in field-deployed units |
| Write Buffer Programming | 32-word buffer cuts effective programming time by >70% vs. single-word writes - critical for fast OTA firmware patching |
| CFI Compliance | Common Flash Interface support enables automatic detection and configuration by bootloader or flash translation layer (FTL) software |
| Suspend/Resume | Interruptible program/erase operations allow real-time servicing of higher-priority tasks - essential for deterministic RTOS environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL256S90TFIR20 | Same density and speed, but TSOP-56 package (T) instead of BGA (F); lacks Fortified BGA mechanical robustness | Better suited for cost-sensitive consumer PCBs with manual rework capability; not recommended for high-vibration telecom modules | Select when board space permits larger footprint and thermal management favors exposed leads over BGA solder joints |
| MX29GL256FHT2I-90G | Micron equivalent; identical 256 Mbit, 90 ns, industrial temp, but uses different command set and lacks secured silicon sector | Requires firmware driver modification; no built-in electronic serial number or factory-lockable identity region | Choose only if CFI-based auto-detection suffices and secure device identity is handled externally via MCU TPM |
Compared with S29GL256S90TFIR20 and MX29GL256FHT2I-90G, the S29GL256P90FACR20 uniquely combines Fortified BGA reliability, VersatileI/O™ voltage agility, and cryptographically traceable secured silicon - making it optimal for safety-critical, long-lifecycle, and mixed-voltage embedded designs.

FAQ
What is the function of the VIO pin on the S29GL256P90FACR20?
The VIO pin supplies the I/O voltage reference for all address, control, and data pins (A23–A0, DQ15–DQ0, CE#/OE#/WE#, etc.). It operates independently from VCC and ranges from 1.65 V to VCC, enabling direct interface with 1.8 V, 2.5 V, or 3.3 V host processors without external level shifters - a key enabler for mixed-voltage system design.
Does the S29GL256P90FACR20 support hardware write protection for specific sectors?
Yes. The WP#/ACC pin provides hardware-level write protection for the highest or lowest 64 Kword sector depending on model configuration (R1/R2/V1/V2). When WP# is driven low, those sectors are locked against program/erase commands regardless of software protection settings - providing fail-safe protection for boot code or calibration data.
How does the secured silicon sector differ from standard flash sectors?
The secured silicon sector is a dedicated 128-word (256-byte) region physically isolated from main array, factory-programmable with a unique 8-word electronic serial number, and lockable via persistent bits or password. Once locked, its contents cannot be erased or rewritten - ensuring permanent, tamper-resistant device identification for traceability and security-critical applications.
Can the S29GL256P90FACR20 be used in place of older S29GL256N devices?
No. While both are 256 Mbit NOR flash, the S29GL256P uses 90 nm MirrorBit process with enhanced VersatileI/O™, write buffer, and secured silicon features absent in the legacy S29GL256N (65 nm). Command sequences and timing parameters differ; migration requires full firmware validation and may need VIO routing adjustments on PCB.
