Product details
Overview
S29GL128P90TFIR23 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 128 uniform 64 Kword sectors, 90 ns random access time, 25 ns page access time, and 100,000 erase cycles per sector - deployed in industrial embedded systems for firmware storage and boot code execution.
For engineers reviewing the S29GL128P90TFIR23 datasheet, S29GL128P90TFIR23 pinout, S29GL128P90TFIR23 application, or S29GL128P90TFIR23 equivalent, key selection criteria include VersatileI/O™ voltage flexibility (VIO = 1.65–VCC), write buffer programming efficiency (64-byte burst), secured silicon sector with factory-programmable ESN, and TSOP-56 industrial-temperature packaging.
Technical Context
This device implements a synchronous/asynchronous hybrid interface with dedicated CE#, OE#, and WE# controls, supporting both word (DQ0–DQ15) and byte (DQ0–DQ7 + DQ15/A-1 as A-1) configurations via BYTE# input. Its internal state machine executes embedded program/erase algorithms with suspend/resume capability and real-time status reporting via RY/BY#.
The 90 nm MirrorBit architecture enables dual-bit-per-cell storage without additional mask steps, while the CFI-compliant command set ensures interoperability with standard flash controllers. Sector protection employs both persistent lock bits and password-based methods, with WP#/ACC providing hardware acceleration at VHH and sector-level write protection at VIL.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 128 Mbit (16 MB), organized as 128 × 64 Kword sectors - defines firmware image capacity and partitioning granularity. |
| Access Time | 90 ns random access (Regulated VCC), 25 ns page access - enables fast instruction fetch in boot ROM applications. |
| Write Buffer Size | 64 bytes (32 words) - reduces effective programming time by >4× vs single-word writes in firmware updates. |
| Erase Endurance | 100,000 cycles per sector - supports field firmware upgrades over 10+ years in industrial control units. |
| Data Retention | 20 years typical - ensures long-term reliability of stored configuration and calibration data. |
| Operating Voltage | VCC = 2.7–3.6 V, VIO = 1.65–VCC - allows I/O voltage scaling independent of core supply for mixed-voltage SoC interfacing. |
| Temperature Range | –40°C to +85°C (Industrial) - qualified for deployment in automotive ECUs and outdoor telecom equipment. |
Pinout & Package
Package: 56-pin Thin Small Outline Package (TSOP-II, Standard Pinout, TSO56), lead-free (Pb-free), industrial temperature grade.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A22–A0 | Address Inputs | 23-bit address bus (A22–A0) selects 128 Mbit memory location; A22 is MSB for this density. |
| DQ15–DQ0 | Data I/O (Word Mode) | 16-bit bidirectional data bus; DQ15/A-1 serves as LSB address in byte mode when BYTE# = VIL. |
| CE# | Chip Enable | Active-low chip select; device enters low-power standby when deasserted. |
| OE# | Output Enable | Active-low read strobe; controls output buffer enable independently of CE# for multiplexed bus timing. |
| WE# | Write Enable | Active-low signal initiating write/erase commands; must be synchronized with address and data setup/hold. |
| RY/BY# | Ready/Busy Output | Open-drain status indicator: low during active program/erase, high-Z when operation complete. |
| RESET# | Hardware Reset | Active-low asynchronous reset; forces device into reading array state and aborts ongoing operations. |
| WP#/ACC | Write Protect / Acceleration | VIL: locks top/bottom sector; VHH: enables unlock-bypass programming for production throughput. |
| BYTE# | Bus Width Select | VIL: enables 8-bit data path (DQ0–DQ7); VIH: enables 16-bit path (DQ0–DQ15). |
| VIO | Versatile I/O Supply | Defines logic threshold for all I/O pins (address, control, data); decouples interface voltage from VCC. |
Key Features
| Feature | Design Value |
|---|---|
| 8-word page read buffer | Enables burst reads at up to 10 MHz, improving sequential instruction fetch bandwidth in microcontroller boot sequences. |
| Secured Silicon Sector (128-word) | Provides factory- or customer-programmable 256-byte region with locked Electronic Serial Number for device authentication and traceability. |
| Advanced Sector Protection | Combines persistent lock bits and password-based unprotection - prevents accidental or malicious firmware overwrite in deployed systems. |
| Suspend/Resume for Program/Erase | Allows interrupting background erase to service high-priority read requests - critical for real-time HMI and control loop responsiveness. |
| CFI (Common Flash Interface) | Standardized JEDEC-compliant query table enables automatic driver detection and configuration in Linux/U-Boot environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Page Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |

FAQ
What is the function of the VIO pin on the S29GL128P90TFIR23?
The VIO pin sets the input voltage threshold and output drive level for all address, control, and data I/O signals. It operates from 1.65 V to VCC (2.7–3.6 V), enabling direct interfacing with 1.8 V, 2.5 V, or 3.3 V logic without external level shifters - a key enabler for mixed-voltage SoC designs.
Does the S29GL128P90TFIR23 support hardware reset during active programming?
Yes. Asserting RESET# asynchronously halts any ongoing program or erase operation, clears internal state machines, and returns the device to read mode. This provides deterministic recovery from power glitches or watchdog timeouts without requiring external sequencing logic.
How does the Secured Silicon Sector differ from standard flash sectors?
The Secured Silicon Sector is a dedicated 128-word (256-byte) region with factory-programmable 8-word Electronic Serial Number and customer-lockable bits. Once locked, its contents cannot be erased or rewritten - unlike standard sectors - making it ideal for immutable device identity and cryptographic key binding.
Can the S29GL128P90TFIR23 be used in byte-mode configuration?
Yes. When BYTE# is driven low, the device operates in 8-bit mode: DQ0–DQ7 become active data lines, and DQ15/A-1 functions as address bit A-1 (LSB). This supports legacy 8-bit microcontrollers and reduces bus routing complexity on space-constrained PCBs.
