Infineon Technologies S29GL256N10TFI010

Overview

S29GL256N10TFI010 from Cypress Semiconductor is a 256 Mbit (33,554,432-byte), 16-bit wide, single-supply 3.0 V Page Flash memory using 110 nm MirrorBit technology. It features 256 × 128 Kbyte sectors, 90 ns access time at regulated 3.0–3.6 V, 1 µA standby current, and supports byte/word configuration via BYTE# input. It is used in industrial control firmware storage where reliable nonvolatile code retention and sector-level erase flexibility are required.

For engineers reviewing the S29GL256N10TFI010 datasheet, S29GL256N10TFI010 pinout, S29GL256N10TFI010 application, or S29GL256N10TFI010 equivalent, key selection criteria include JEDEC-compliant command set, VIO-adjustable I/O voltage (1.65–VCC), Secured Silicon Sector with 128-word serial ID, Erase/Program Suspend capability, and TSOP-56 or FBGA-64 package compatibility.

Technical Context

This device implements a sector-erase architecture with 256 independent 128 Kbyte sectors, enabling selective reprogramming without disturbing adjacent firmware regions. Its Enhanced VersatileI/O™ control ties all address, control, and data input thresholds to the VIO pin voltage, allowing seamless integration into mixed-voltage systems (1.8 V or 3.0 V logic domains).

Internally, it uses hot-electron injection for programming and hot-hole assisted erase, delivering 100,000 erase cycles per sector and 20-year data retention. Command execution-including Autoselect, Sector Erase, Word Program, and Secured Silicon access-is performed via standard microprocessor write timing with no external high-voltage supply required.

Manufacturer

Cypress Semiconductor (now part of Infineon Technologies) is a fabless semiconductor company specializing in embedded solutions, including PSoC, NOR/NAND flash, and USB controllers.

The S29GL-N family was designed for high-reliability, sector-erasable code storage in industrial, medical, and communications systems requiring JEDEC-compliant, single-supply flash with advanced security and suspend capabilities.

FAQ

Is S29GL256N10TFI010 still in production?

No - Cypress officially retired the S29GL-N family and does not recommend it for new designs. However, Aetrix Electronics maintains legacy inventory and provides traceable, tested units for continuity support in existing production programs and repair channels.

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

WP#/ACC serves dual roles: when pulled low, it hardware-protects the first or last sector; when driven high with VCC applied, it enables accelerated programming current to reduce write time during manufacturing. It is not a general-purpose write protect for all sectors.

Can S29GL256N10TFI010 operate with a 1.8 V host interface?

Yes - by setting VIO = 1.8 V, all input thresholds and output drive levels adapt to 1.8 V logic, enabling direct connection to 1.8 V FPGAs or ASICs without level shifters. VCC remains at 3.0 V for core memory operation.

Does this device support true 8-bit bus operation?

Yes - asserting BYTE# low configures the device for 8-bit mode, where only DQ0–DQ7 are active and DQ8–DQ15 are tri-stated. Addressing remains word-based internally, but data transfers occur on the lower byte lane only.
