Product details

Overview

S29GL128P11TFI023 from Cypress Semiconductor is a 128 Mbit (16 MB) 3.0 V-only Page Mode Flash memory fabricated on 90 nm MirrorBit process technology, featuring 128 uniform 64 Kword (128 Kbyte) sectors, 25 ns page access time, and 90 ns random access time under regulated VCC. It supports VersatileI/O™ with VIO range 1.65–VCC, includes a 32-word write buffer for accelerated multi-word programming, and integrates Secured Silicon Sector with factory- or customer-programmable 8-word electronic serial number - deployed in industrial-grade embedded boot code storage.

For engineers reviewing the S29GL128P11TFI023 datasheet, S29GL128P11TFI023 pinout, S29GL128P11TFI023 application, or S29GL128P11TFI023 equivalent, key selection criteria include sector erase endurance (100,000 cycles), 20-year data retention, TSOP-56 industrial temperature support (–40°C to +85°C), and CFI-compliant interface compatibility for legacy NOR flash migration paths.

Technical Context

This device operates as a parallel-interface NOR Flash memory with byte/word configuration selectable via BYTE# input, supporting standard read, page read, program, and sector erase operations governed by command sequences compliant with Common Flash Interface (CFI). Its architecture includes dedicated erase voltage and programming voltage generators, state control logic, and a command register that interprets unlock-bypass and suspend/resume commands.

Power management features include automatic sleep mode, standby current of 1 µA, and hardware reset (RESET#) with RY/BY# status output for real-time operation monitoring. The VersatileI/O™ interface decouples I/O voltage (VIO) from core supply (VCC), enabling interoperability with mixed-voltage microcontrollers while maintaining signal integrity across 1.65–3.6 V VIO range.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	128 Mbit (16 MB), organized as 128 × 64 Kword sectors - enables full boot image storage for mid-tier microcontrollers.
Access Time	90 ns random access / 25 ns page access at regulated VCC = 3.0–3.6 V - meets timing requirements for 11 MHz bus interfaces.
Write Buffer Size	32 words (64 bytes) - reduces effective programming time by >75% vs. single-word writes in firmware update scenarios.
Erase Endurance	100,000 cycles per sector - supports field firmware updates over 10+ years in industrial control applications.
Data Retention	20 years typical at +85°C - ensures long-term reliability without refresh in unpowered storage.
Operating Voltage	VCC = 2.7–3.6 V, VIO = 1.65–VCC - allows direct interfacing with 1.8 V, 2.5 V, or 3.3 V host processors.
Temperature Range	Industrial: –40°C to +85°C - qualified for deployment in automotive body control modules and industrial HMIs.

Pinout & Package

Package: 56-pin Thin Small Outline Package (TSOP), 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 128 Mbit density.
DQ15–DQ0	Data I/O Bus	16-bit bidirectional data path; DQ15/A-1 serves as LSB address in byte mode when BYTE# = VIL.
CE#, OE#, WE#	Control Inputs	Standard chip enable, output enable, and write enable signals - compatible with asynchronous SRAM timing protocols.
BYTE#	Bus Width Select	Configures 8-bit (DQ0–DQ7 active) or 16-bit (DQ0–DQ15 active) data interface - simplifies integration with 8-/16-bit MCUs.
WP#/ACC	Write Protect / Acceleration	At VIL: protects top/bottom sector; at VHH: enables unlock-bypass programming for production-line throughput boost.
RY/BY#	Status Output	Active-low open-drain signal indicates ongoing program/erase - eliminates need for polling delay loops in firmware.
RESET#	Hardware Reset	Asynchronous reset input forces device into read mode - critical for safe recovery after power brownout or watchdog timeout.

Key Features

Feature	Design Value
Uniform Sector Architecture	128 identical 64 Kword sectors simplify firmware partitioning and enable deterministic erase scheduling in OTA update stacks.
Secured Silicon Sector	128-word factory-lockable region stores immutable device ID or cryptographic keys - prevents cloning in secure boot implementations.
Advanced Sector Protection	Persistent lock bits and password-based protection allow selective sector lockdown - essential for protecting bootloader and calibration data.
Suspend/Resume Commands	Pause active erase or program operations to service high-priority reads - maintains system responsiveness during background flash maintenance.
CFI Compliance	Standardized JEDEC JESD68 interface enables auto-detection and driver portability across NOR flash families in Linux/RTOS BSPs.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NOR Flash memory applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL128S11TFI020	Same density and package, but 65 nm Eclipse process; 110 ns random access, lower active current (25 mA vs. 30 mA)	Higher power efficiency in battery-backed systems; slightly slower read timing requires bus timing adjustment	Select for new designs prioritizing power savings over marginal speed loss; not drop-in due to AC timing changes
MX29GL128FPTI-90G	128 Mbit, 90 ns, TSOP-56, but lacks Secured Silicon Sector and VersatileI/O; VIO fixed at VCC	No electronic serial number or mixed-voltage I/O - limits use in secure or heterogeneous voltage systems	Choose only when cost sensitivity outweighs security and flexibility requirements; verify CFI descriptor compatibility

Compared with S29GL128P11TFI023, the S29GL128S11TFI020 offers better power efficiency at minor timing cost, while MX29GL128FPTI-90G sacrifices security and voltage flexibility for lower unit price - making the original optimal for industrial designs needing both robustness and configurability.

Manufacturer

Cypress Semiconductor (now part of Infineon Technologies) is a fabless semiconductor company specializing in high-reliability memory, PSoC, and USB-C solutions for industrial, automotive, and IoT markets.

FAQ

Is S29GL128P11TFI023 compatible with legacy S29GL-P series designs?

Yes - it shares identical pinout, command set, and electrical characteristics with other S29GL128P variants in the same speed/package/temperature grade. The "11" speed grade denotes 110 ns random access under full VCC conditions, matching documented timing for industrial TSOP configurations. No PCB or firmware changes are required for substitution within the same model number family.

What is the function of the WP#/ACC pin during programming?

When driven to VHH (typically 11–12 V), WP#/ACC enables Unlock Bypass Program mode, eliminating the need for repeated unlock commands and reducing programming time by up to 40%. In standard operation, it must be held at VIH; pulling it low protects the top or bottom sector from accidental erasure or programming, independent of software protection settings.

Does this device support byte-mode operation?

Yes - asserting BYTE# = VIL configures the device for 8-bit data bus operation, activating DQ0–DQ7 and repurposing DQ15/A-1 as the LSB address input (A-1). This mode is fully supported in all read, program, and erase operations and maintains full sector protection and security features without performance penalty.

How is the Secured Silicon Sector programmed and locked?

The 128-word Secured Silicon Sector is programmed using standard CFI command sequences, then permanently locked via a dedicated lock bit. Factory locking occurs during wafer test; customer locking is performed by writing to the lock register after programming. Once locked, the sector becomes read-only and immune to erase commands - verified by reading status register bit 7 (SEC) = 1.
