Product details
Overview
S29GL128P90FAIR22 from Cypress Semiconductor is a 128 Mbit (16 MB), 3.0 V-only Page Flash memory IC fabricated on 90 nm MirrorBit process technology, featuring 90 ns random access time, 25 ns page access time, uniform 64 Kword (128 KB) sector architecture (128 sectors), and 100,000 erase cycles per sector - deployed in industrial embedded systems for firmware storage and boot code execution.
For engineers reviewing the S29GL128P90FAIR22 datasheet, S29GL128P90FAIR22 pinout, S29GL128P90FAIR22 application, or S29GL128P90FAIR22 equivalent, key selection criteria include VersatileI/O™ voltage flexibility (VIO = 1.65–VCC), write buffer programming efficiency (64-byte buffer), secured silicon sector with factory-programmable ESN, and CFI-compliant interface for standardized flash management.
Technical Context
This device implements a synchronous/asynchronous hybrid command-set architecture with hardware reset (RESET#), ready/busy status signaling (RY/BY#), and dual protection modes: persistent sector lock bits and password-based Advanced Sector Protection. It supports byte/word configuration via BYTE# input and operates across full VCC (2.7–3.6 V) or regulated VCC (3.0–3.6 V) with VersatileI/O™ decoupling of I/O voltage from core supply.
The internal block diagram integrates X/Y decoders, erase/program voltage generators, state control logic, and command register with autoselect and suspend/resume capability. Sector erase time is fixed at 0.5 s per 64 Kword sector, and effective write buffer programming achieves 13.5 µs/word when VHH acceleration is applied to WP#/ACC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 128 Mbit (16 MB) organized as 2,097,152 × 8 or 1,048,576 × 16 - supports boot ROM and firmware image storage in space-constrained designs. |
| Access Time | 90 ns random access (Regulated VCC); 25 ns page access - enables fast instruction fetch in real-time microcontroller boot sequences. |
| Write Buffer Size | 64 bytes (32 words) - reduces total programming time for multi-word updates by eliminating repeated command overhead. |
| Erase Endurance | 100,000 cycles per sector - suitable for field-upgradable firmware requiring frequent reprogramming during product lifecycle. |
| Data Retention | 20 years typical - ensures long-term reliability in unattended industrial equipment without refresh mechanisms. |

Pinout & Package
Package: 64-ball Fortified BGA (LAA064, 11 × 13 mm, 1.0 mm pitch), RoHS-compliant, Pb-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A22–A0 | Address Inputs | 23-bit address bus (A22–A0) selects 128 Kbyte sectors and 16-byte pages; A22 is MSB for 128 Mbit density. |
| DQ15/A-1 | Multi-function I/O | In word mode: DQ15 data line; in byte mode: A-1 LSB address - enables flexible 8-/16-bit host bus compatibility. |
| WP#/ACC | Write Protect / Acceleration Input | At VIL: protects top/bottom sector; at VHH: enables unlock bypass mode and accelerates programming throughput. |
| RY/BY# | Open-drain Status Output | Active-low signal indicates active program/erase; high-impedance = operation complete - simplifies polling-based firmware control. |
| RESET# | Hardware Reset Input | Asynchronous active-low reset returns device to read mode and aborts ongoing operations - critical for system recovery. |
| VIO | Versatile I/O Supply | Independent voltage reference for all I/O pins (address, data, control); decouples interface voltage from VCC domain. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Page Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL128S90TFI020 | Same 128 Mbit density and 90 nm MirrorBit process, but TSOP-56 package (vs. BGA); no Secured Silicon Sector; VIO range limited to VCC only. | Lacks factory-programmable ESN and VersatileI/O™ flexibility - unsuitable for secure or mixed-voltage designs. | Select when board layout requires through-hole-compatible footprint and security features are not required. |
| MX29GL128FHT2I-90G | Macronix 128 Mbit Page Flash; 90 ns access; 64-ball BGA; supports CFI but lacks Secured Silicon Sector and WP#/ACC acceleration. | No hardware-accelerated programming or factory-locked serial number - limits use in high-security or high-throughput production lines. | Choose for cost-sensitive applications where CFI compatibility and BGA footprint match are primary, not security or programming speed. |
Compared with S29GL128S90TFI020 and MX29GL128FHT2I-90G, the S29GL128P90FAIR22 uniquely combines industrial-grade BGA packaging, VersatileI/O™ voltage independence, hardware-accelerated programming, and factory-lockable secure silicon - making it optimal for secure, high-reliability embedded boot applications.

FAQ
What is the function of the WP#/ACC pin on S29GL128P90FAIR22?
The WP#/ACC pin serves two distinct roles: at VIL, it hardware-protects the top or bottom sector from accidental program/erase; at VHH (12 V), it enables Unlock Bypass Program mode and accelerates programming throughput. Its internal pull-up ensures default VIH state when unconnected, preventing unintended lockout during initialization.
Does S29GL128P90FAIR22 support both byte and word data configurations?
Yes - the BYTE# input determines bus width: at VIL, the device operates in byte mode (DQ0–DQ7 active, DQ15/A-1 becomes A-1 address input); at VIH, it operates in word mode (DQ0–DQ15 active). This dual-mode capability allows seamless integration with 8-bit and 16-bit microcontroller buses without external glue logic.
How does the Secured Silicon Sector differ from standard flash sectors?
The Secured Silicon Sector is a dedicated 128-word (256-byte) region that can be permanently locked by the factory or end user. It contains an 8-word electronic serial number and supports one-time programmable fields. Unlike standard sectors, it cannot be erased after locking and is isolated from standard command sequences unless explicitly accessed via Secured Silicon Entry commands.
Can S29GL128P90FAIR22 be used in systems with mixed I/O voltage domains?
Yes - VersatileI/O™ allows VIO to operate independently from VCC across 1.65 V to VCC. For example, with VCC = 3.3 V and VIO = 1.8 V, all address, data, and control signals interface directly with 1.8 V logic, eliminating level shifters while maintaining full functionality including CFI queries and write buffer operations.
