Infineon Technologies S29GL128N10FFI010

Overview

S29GL128N10FFI010 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, 25 ns page read time, and 100,000 erase cycles per sector. It supports flexible sector architecture (128 × 64 Kword sectors), CFI compliance, and operates in 1.65–3.6 V VIO range for mixed-voltage system interfacing.

For engineers reviewing the S29GL128N10FFI010 datasheet, S29GL128N10FFI010 pinout, S29GL128N10FFI010 application, or S29GL128N10FFI010 equivalent, key selection criteria include JEDEC software compatibility, Secured Silicon Sector with 128-word ESN, Enhanced VersatileI/O™ voltage flexibility, and hardware reset (RESET#) with RY/BY# status signaling.

Technical Context

This device implements a command-set-compatible NOR Flash architecture with separate CE#, WE#, and OE# controls, enabling standard microprocessor bus interfacing without glue logic. Its sector erase topology allows independent reprogramming of 128 Kbyte sectors while preserving data elsewhere, and it uses hot-electron injection for programming and hot-hole assisted erase.

The Enhanced VersatileI/O™ interface decouples I/O voltage levels from VCC by referencing all address, control, and DQ signals to the externally supplied VIO pin (1.65–3.6 V), permitting seamless integration into both 1.8 V and 3.3 V host systems. Internal state machines manage Program/Erase Suspend & Resume, Unlock Bypass, and password-protected sector locking without host CPU intervention.

FAQ

Is S29GL128N10FFI010 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No. Cypress explicitly states this part is "Not Recommended for New Design" and has been superseded by the S29GL128S series.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 support and last-time buy scenarios, but new projects should migrate to S29GL128S10FFI010 for continued technical and supply chain support.

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

The WP#/ACC pin serves dual roles: when pulled low, it hardware-protects the first or last sector against accidental writes; when driven to 5.5 V (via external charge pump), it accelerates programming time by increasing internal current - a feature intended for high-throughput factory programming, not field use.

Does S29GL128N10FFI010 support 8-bit data bus operation?

Yes. When the BYTE# input is asserted low, the device operates in 8-bit mode, presenting DQ0–DQ7 as the data bus while internally managing 16-bit word alignment. This enables compatibility with legacy 8-bit microcontrollers without external data-width conversion logic.

How is the Secured Silicon Sector accessed and locked?

The Secured Silicon Sector is accessed via a specific command sequence (enter/exit commands defined in Section 9.15–9.16 of the datasheet) and contains a factory-programmed or customer-programmable 8-word electronic serial number. Once locked via the Lock Register command, no further writes or erases are possible - providing permanent, tamper-resistant device identity.
