Product details

Overview

S29GL128N10FFI020 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, featuring 90 ns access time, 100,000 erase cycles per sector, and 20-year data retention. It supports flexible sector architecture with 128 × 64 Kword (128 Kbyte) sectors and operates in industrial temperature range (–40°C to +85°C) in a 56-pin TSOP package.

For engineers reviewing the S29GL128N10FFI020 datasheet, S29GL128N10FFI020 pinout, S29GL128N10FFI020 application, or S29GL128N10FFI020 equivalent, key selection criteria include JEDEC-compliant command set, Enhanced VersatileI/O™ (VIO = 1.65–3.6 V), Secured Silicon Sector with 128-word ESN, and hardware reset (RESET#) for boot firmware recovery in embedded systems.

Technical Context

This device implements a sector-erase flash architecture with independent program/erase suspend/resume capability, enabling concurrent read operations during background programming or erasing. It uses hot-electron injection for write and hot-hole assisted erase, with status monitoring via DQ7 polling, DQ6 toggle bits, and RY/BY# output.

The Enhanced VersatileI/O™ control decouples I/O voltage (VIO) from core supply (VCC), allowing interoperability with 1.8 V or 3.0 V host buses. Sector protection includes persistent lock bits, password-based 64-bit authentication, and hardware WP#/ACC acceleration for factory programming throughput.

Equivalent & Alternatives

The following parts are listed as comparable options for similar page flash memory applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL128S10FFI020	Successor part with 65 nm MirrorBit process; 90 ns access, same 56-pin TSOP, but improved 125,000 erase cycles and lower standby current (500 nA).	Designed for new designs requiring extended lifecycle support and reduced power in always-on networking equipment.	Select when long-term availability, lower leakage, and Cypress's active product roadmap are required.
MX29GL128FHI-90G	Macronix equivalent; 90 ns access, 128 Mbit, 56-pin TSOP, JEDEC-compatible command set, but lacks Secured Silicon Sector and password protection.	Suitable for cost-sensitive industrial controls where security features are not mandated.	Choose only if Secured Silicon and password protection are unnecessary and second-source qualification is prioritized.

Compared with S29GL128N10FFI020, the S29GL128S10FFI020 offers higher endurance and longer manufacturer support, while the MX29GL128FHI-90G trades security features for broader distributor availability - making the original optimal for legacy maintenance where its proven field reliability outweighs obsolescence risk.

Manufacturer

Cypress Semiconductor (now part of Infineon Technologies) is a U.S.-based semiconductor company specializing in non-volatile memory, microcontrollers, and connectivity solutions for industrial, automotive, and consumer applications.

The S29GL-N family was designed specifically for high-reliability, single-power-supply embedded boot and firmware storage, emphasizing sector-level flexibility, hardware security, and JEDEC interoperability in space- and power-constrained systems.

FAQ

Is S29GL128N10FFI020 still in production?

No - Cypress officially retired the S29GL-N family and recommends migration to S29GL-S (e.g., S29GL128S) or S29GL-T series. However, Aetrix Electronics maintains limited legacy inventory with full traceability and extended lifecycle support for existing designs undergoing maintenance or phase-out.

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

The WP#/ACC pin serves dual roles: when held low, it protects the first or last sector from accidental writes; when driven to VCC + 2.5 V (via external charge pump), it accelerates programming current for faster factory programming - a feature intended for production-line throughput, not field use.

Does S29GL128N10FFI020 support 8-bit data bus operation?

Yes - asserting BYTE# low configures the device for 8-bit data mode, mapping DQ0–DQ7 as the data bus while disabling DQ8–DQ15. This allows compatibility with 8-bit microcontrollers without external data bus multiplexing or glue logic.

How is the Secured Silicon Sector programmed and locked?

The Secured Silicon Sector is programmed using the standard Word Program command sequence after entering Secured Silicon Sector mode via the dedicated command set. Locking is performed with the Sector Lock command; once locked, no further writes or erases are possible - even with RESET# asserted - ensuring permanent device identity and firmware integrity.
