Product details

Overview

S29GL128N11FFI020 from Cypress Semiconductor is a 128 Mbit (16 MB), 16-bit wide, single-supply 3.0 V Page Flash memory using 110 nm MirrorBit technology, organized as 8,388,608 words × 16 bits, with 90 ns access time, 25 ns page read time, and 100,000 erase cycles per sector - deployed in boot code storage for industrial control systems requiring nonvolatile firmware retention.

For engineers reviewing the S29GL128N11FFI020 datasheet, S29GL128N11FFI020 pinout, S29GL128N11FFI020 application, or S29GL128N11FFI020 equivalent, key selection criteria include JEDEC-compliant command set, Secured Silicon Sector with 128-word ESN, Enhanced VersatileI/O™ (VIO = 1.65–3.6 V), and hardware reset (RESET#) support for reliable system initialization.

Technical Context

This device implements a sector-erase architecture with 128 independent 64 Kword (128 Kbyte) sectors, enabling selective reprogramming without disturbing adjacent data. It supports both byte (via BYTE#) and word operations, and integrates CFI (Common Flash Interface) for automatic host identification and configuration.

Hardware features include WP#/ACC for accelerated programming, RY/BY# status output, and persistent/password-based sector protection. The VIO input decouples I/O voltage from VCC, allowing interoperability with 1.8 V or 3.0 V host buses while maintaining full 3.0 V core operation.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	128 Mbit (16 MB), organized as 8,388,608 × 16-bit words - sufficient for full bootloader + firmware image in space-constrained embedded hosts.

Erase Endurance	100,000 cycles per sector - supports field firmware updates over 10+ years in industrial gateways with monthly OTA patches.
Data Retention	20 years typical - ensures long-term reliability in unattended infrastructure equipment without battery backup.
Supply Voltage	VCC = 2.7–3.6 V, VIO = 1.65–3.6 V - allows seamless integration into mixed-voltage SoC designs with 1.8 V I/O and 3.3 V power domains.
Page Read Buffer	8-word (16-byte) buffer with 25 ns page access - reduces sequential read latency by >60% vs. standard random-access flash.
Write Buffer	16-word (32-byte) write buffer - cuts multi-word programming time by eliminating per-word command overhead.

Pinout & Package

Package: 56-pin TSOP (Thin Small Outline Package), lead-free, RoHS-compliant, 14 mm × 20 mm body size. Pin compatibility maintained across S29GL-N family for drop-in replacement within same density tier.

Pin/Terminal	Circuit Role	Design Meaning
A0–A22	Address Inputs	23-bit address bus supporting full 128 Mbit addressing; A22 is MSB - no external address multiplexing required.
DQ0–DQ15	Data I/O	16-bit bidirectional data bus; BYTE# pin enables 8-bit mode for legacy 8-bit microcontrollers.
CE#, OE#, WE#	Chip/Output/Write Enable	Independent three-control interface eliminates bus contention; supports standard microprocessor timing without glue logic.
RESET#	Hardware Reset Input	Asynchronous active-low reset terminates ongoing erase/program and returns device to read mode - critical for safe power-cycle recovery.
RY/BY#	Ready/Busy Output	Open-drain status signal indicates active programming/erasing - enables interrupt-driven host polling instead of constant software polling.
VIO	I/O Voltage Reference	Configures all input thresholds and output drive levels to match host I/O voltage (1.65–3.6 V), enabling mixed-voltage system integration.
WP#/ACC	Write Protect / Accelerated Program	Low-active write protect for top/bottom sector; high-voltage mode (when VCC ≥ 3.0 V) reduces program time by ~40% during factory programming.

Key Features

Feature	Design Value
Secured Silicon Sector	128-word (256-byte) factory- or user-lockable region with 8-word electronic serial number - provides immutable device identity for secure boot and license enforcement.
Program/Erase Suspend	Allows pausing active program/erase to service higher-priority reads from other sectors - essential for real-time OS environments with concurrent firmware and data access.
Enhanced VersatileI/O™	VIO pin sets all I/O voltage thresholds and drive strength - eliminates level shifters when interfacing with 1.8 V FPGAs or 3.3 V MCUs.
CFI Compliance	Standardized query table at fixed address enables automatic detection and configuration by bootloader - removes hard-coded flash parameters from firmware.
Password Sector Protection	64-bit user-defined password secures any sector combination against unauthorized erase/write - meets IEC 62443-3-3 requirements for industrial firmware integrity.

Manufacturer

Cypress Semiconductor (now part of Infineon Technologies) is a global leader in embedded solutions, specializing in high-reliability nonvolatile memory, PSoC programmable systems-on-chip, and USB-C/power delivery ICs.

The S29GL-N family was designed for mission-critical embedded boot and firmware storage in industrial, medical, and communications equipment where data integrity, long-term retention, and secure identity are mandatory.

FAQ

Is S29GL128N11FFI020 still recommended for new designs?

No - Cypress explicitly states this part is "Not Recommended for New Design" and has been superseded by the S29GL128S series. It remains available for legacy production and repair, but new projects should use S29GL128S11FFI020 or verified alternatives like MX29GL128FHI-90G with appropriate qualification.

What is the function of the VIO pin, and why does it matter?

The VIO pin sets the voltage reference for all input thresholds and output drive levels. With VIO = 1.65–3.6 V, the device operates correctly alongside 1.8 V FPGAs or 3.3 V microcontrollers without external level shifters - simplifying board design and improving signal integrity in mixed-voltage systems.

Can the Secured Silicon Sector be reprogrammed after locking?

No - once the Secured Silicon Sector is permanently locked (via command sequence), it becomes read-only and cannot be erased or rewritten. The 8-word electronic serial number is factory-programmed and immutable; customer data written to this region before locking remains permanently secured.

How does Program Suspend improve real-time system responsiveness?

Program Suspend allows the host to interrupt an ongoing word-program operation, read from another sector (e.g., sensor data or interrupt handler code), then resume programming - avoiding blocking delays. This enables deterministic response times in RTOS-based systems where flash writes must not stall time-critical tasks.
