Product details

Overview

S29GL128P11TFIV20 from Cypress Semiconductor is a 128 Mbit (16 MB) single-supply 3.0 V page-mode NOR Flash memory fabricated on 90 nm MirrorBit process technology, featuring 25 ns page access time, 90 ns random access time, uniform 64 Kword (128 Kbyte) 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 S29GL128P11TFIV20 datasheet, S29GL128P11TFIV20 pinout, S29GL128P11TFIV20 application, or S29GL128P11TFIV20 equivalent, this device supports VersatileI/O™ (VIO = 1.65–VCC), CFI-compliant interface, hardware reset (RESET#), ready/busy status (RY/BY#), and dual protection modes (Persistent/Password) for secure firmware updates in resource-constrained edge devices.

Technical Context

This NOR Flash implements a synchronous command-set architecture with embedded program/erase algorithms, supporting byte/word configuration via BYTE# input and selectable VIO voltage for I/O level translation independent of VCC. It integrates a 32-word write buffer to accelerate multi-word programming and suspend/resume capability for real-time interrupt handling during erase operations.

The device uses a dedicated sector-switch matrix and X/Y decoder architecture to enable fast random and page read access. Its Secured Silicon Sector provides factory- or customer-programmable 128-word electronic serial number with lockable security, while WP#/ACC serves dual roles: hardware write protection and VHH-accelerated programming during production.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	128 Mbit (16 MB), organized as 128 × 64 Kword uniform sectors - enables deterministic firmware partitioning and OTA update rollback.
Access Time	90 ns random / 25 ns page access at regulated VCC (3.0–3.6 V) - meets real-time boot latency requirements in industrial controllers.
Write Buffer Size	32 words (64 bytes) - reduces effective programming time by >75% vs. single-word writes for firmware patching.
Erase Endurance	100,000 cycles per sector - supports field firmware updates over 10+ years in unattended equipment.
Data Retention	20 years typical at +85°C - ensures long-term reliability in automotive under-hood and industrial control cabinet environments.
VersatileI/O Range	VIO = 1.65 V to VCC (2.7–3.6 V) - allows direct interfacing with 1.8 V, 2.5 V, or 3.3 V host processors without level shifters.
Operating Temp	–40°C to +85°C (Industrial grade) - qualified for deployment in outdoor telecom base stations and factory automation PLCs.

Pinout & Package

Package: 56-pin TSOP (Standard Thin Small Outline Package, TSO56), lead-free, industrial temperature grade.

Pin/Terminal	Circuit Role	Design Meaning
A22–A0	Address Inputs	23-bit address bus (A22–A0) selects 128 Kbyte sectors and internal word locations - A22 is MSB for 128 Mbit density.
DQ15–DQ0	Data I/O Bus	16-bit bidirectional data path; DQ15/A-1 functions as LSB address in byte mode when BYTE# = VIL.
CE#, OE#, WE#	Chip/Output/Write Enable	Standard JEDEC-compliant control signals - CE# enables device, OE# gates output drivers, WE# initiates write cycles.
RY/BY#	Ready/Busy Output	Active-low open-drain signal indicates active program/erase - used for polling or interrupt-driven status monitoring.
RESET#	Hardware Reset Input	Asynchronous active-low reset that aborts ongoing operations and returns device to read mode - critical for system recovery.
WP#/ACC	Write Protect / Acceleration	At VIL: protects top/bottom sector; at VHH: enables unlock-bypass programming - supports both security and high-throughput manufacturing.
VIO	Versatile I/O Supply	Independent voltage reference for all I/O pins - decouples logic interface voltage from core VCC, enabling mixed-voltage system integration.

Key Features

Feature	Design Value
Uniform Sector Architecture	128 identical 64 Kword sectors simplify firmware image layout, wear leveling, and flash translation layer implementation.
Secured Silicon Sector	128-word factory- or customer-lockable region stores immutable electronic serial number - enables device authentication and anti-cloning.
Advanced Sector Protection	Persistent bits + password method allow selective, non-volatile sector locking - prevents accidental or malicious firmware corruption.
Write Buffer Programming	32-word buffer reduces average programming time to 13.5 µs/word with VHH - accelerates field firmware upgrades by up to 4×.
Suspend/Resume Capability	Interrupts erase or program operations to service high-priority reads - essential for real-time OS environments with concurrent access.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MX29GL128FPTI-90G	128 Mbit, 90 ns access, 3.0 V, 56-pin TSOP - lacks VersatileI/O and Secured Silicon Sector; uses standard VCC-referenced I/O.	No VIO flexibility or hardware-locked serial number - requires external security IC for device authentication.	Select when cost sensitivity outweighs need for mixed-voltage interface or built-in security features.
S29GL128S11TFIV20	Same density and package, but 65 nm Eclipse process - improved 1.8 V VIO support, lower standby current (100 nA vs. 1 µA), and faster 13 ns write buffer programming.	Better suited for battery-powered edge nodes; not backward-compatible due to timing and command set differences.	Choose for new designs prioritizing ultra-low power and next-gen process benefits - not drop-in replaceable.

Compared with MX29GL128FPTI-90G, S29GL128P11TFIV20 delivers hardware-enforced security and voltage-flexible I/O; versus S29GL128S11TFIV20, it offers proven industrial qualification and broader ecosystem tool support despite higher power and older node.

FAQ

What is the function of the VIO pin on S29GL128P11TFIV20?

The VIO pin sets the voltage reference for all input and output signal levels (address, control, and DQ), independent of VCC. With VIO ranging from 1.65 V to VCC (2.7–3.6 V), it enables direct interfacing with 1.8 V or 2.5 V host processors without external level shifters - a key enabler for mixed-voltage system design.

Does S29GL128P11TFIV20 support hardware reset, and how is it implemented?

Yes, it features an active-low hardware RESET# input. When asserted, RESET# immediately terminates any ongoing program or erase operation and forces the device into reading array data mode. This provides deterministic recovery from fault conditions and is essential for fail-safe embedded boot sequences.

How does the Secured Silicon Sector work, and who can program it?

The Secured Silicon Sector is a dedicated 128-word (256-byte) region containing an 8-word electronic serial number. It can be programmed and permanently locked either at the factory or by the end customer using specific command sequences. Once locked, contents cannot be altered - providing tamper-resistant device identification.

What is the difference between WP# and ACC functionality on the WP#/ACC pin?

When pulled low (VIL), WP# protects the top or bottom sector from program/erase. When driven to VHH (~11.5 V), the same pin enables acceleration mode: automatic entry into unlock-bypass programming, reducing single-word programming time from 60 µs to 13.5 µs - optimized for high-volume manufacturing throughput.
