Infineon Technologies S29GL128N11TAI010

Overview

S29GL128N11TAI010 from Cypress Semiconductor is a 128 Mbit (16 MB), 3.0 V single-power-supply NOR Flash memory using 110 nm MirrorBit technology, organized as 8,388,608 words × 16 bits, with 90 ns access time, 128 Kbyte uniform sectors, and CFI-compliant command set. It supports byte/word configuration via BYTE# input and operates in industrial temperature range (–40°C to +85°C) in a 56-pin TSOP package.

For engineers reviewing the S29GL128N11TAI010 datasheet, S29GL128N11TAI010 pinout, S29GL128N11TAI010 application, or S29GL128N11TAI010 equivalent, key selection criteria include sector erase architecture, VIO voltage flexibility (1.65–3.6 V), Secured Silicon Sector for electronic serial number, and hardware reset (RESET#) and ready/busy (RY/BY#) signaling for embedded boot code storage.

Technical Context

This device implements a JEDEC-standard command-set-compatible NOR Flash architecture with separate CE#, WE#, and OE# controls, enabling deterministic read/write/erase timing in microcontroller-based boot memory systems. Its Enhanced VersatileI/O™ (VIO) allows independent I/O voltage setting (1.65–3.6 V), decoupling interface logic levels from core VCC (2.7–3.6 V).

The 128-sector layout (each 64 Kwords / 128 Kbytes) supports selective erase without disturbing adjacent sectors. Internal hot-hole erase and hot-electron programming deliver 100,000 erase cycles per sector and 20-year data retention, validated under industrial operating conditions.

S29GL128N11TAI010 is available at Aetrix Electronics and suitable for industrial PLC firmware storage, automotive ECU boot memory, and medical device configuration storage requiring stable component supply despite end-of-life status.

Supply support for S29GL128N11TAI010 includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Cypress Semiconductor (now part of Infineon Technologies) is a fabless semiconductor company specializing in embedded systems solutions, including microcontrollers, connectivity, and non-volatile memory.

The S29GL-N family was designed specifically for reliable, high-density boot code and firmware storage in industrial, automotive, and networking equipment requiring JEDEC-compliant NOR Flash with advanced security and sector management.

FAQ

Is S29GL128N11TAI010 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 designs should use S29GL128S11TFI010 or later equivalents to ensure long-term supply and technical support.

What is the function of the WP#/ACC pin in normal operation?

In normal operation, WP# (Write Protect) is an active-low input that permanently protects the first or last sector from accidental erase or program when asserted. When driven high and VCC ≥ 3.0 V, it enables ACC (Accelerated Program) mode, reducing programming time by ~30% - intended for high-throughput manufacturing, not field use.

How does the Secured Silicon Sector differ from standard flash sectors?

The Secured Silicon Sector is a dedicated 128-word (256-byte) region physically isolated from main array. Once locked (via command sequence), it becomes permanently read-only and immune to bulk erase. It contains a factory-programmed 8-word electronic serial number and supports customer programming of custom identification or keys before final lock.

Can S29GL128N11TAI010 operate with VIO = 1.8 V while VCC = 3.3 V?

Yes. The Enhanced VersatileI/O™ architecture allows VIO to be set independently from VCC within 1.65–3.6 V. With VIO = 1.8 V and VCC = 3.3 V, all address, control, and DQ pins conform to 1.8 V logic thresholds, enabling direct interfacing with 1.8 V microcontrollers without level-shifting circuitry.
