Product details
Overview
S29GL256N11FAI020 from Cypress Semiconductor is a 256 Mbit (33,554,432-byte), 16-bit-wide, single-supply 3.0 V Page Flash memory manufactured on 110 nm MirrorBit process technology. It features 256 × 128 Kbyte sectors, 90 ns access time (at regulated VCC/VIO), 100,000 erase cycles per sector, and Secured Silicon Sector with 256-byte factory-lockable serial ID. Used in industrial control firmware storage and boot code retention where long-term data integrity and hardware-based write protection are required.
For engineers reviewing the S29GL256N11FAI020 datasheet, S29GL256N11FAI020 pinout, S29GL256N11FAI020 application, or S29GL256N11FAI020 equivalent, key selection considerations include JEDEC-compliant command set compatibility, Enhanced VersatileI/O™ voltage flexibility (1.65–3.6 V VIO), sector-level erase granularity, CFI compliance for auto-configuration, and hardware reset (RESET#) with RY/BY# status signaling.
Technical Context
This device implements a NOR flash architecture with separate CE#, WE#, and OE# controls, enabling true random-access read and page-buffered programming. Its 110 nm MirrorBit cell design supports hot-electron injection for programming and hot-hole assisted erase, delivering stable 20-year data retention and 1 µA standby current.
The Enhanced VersatileI/O™ interface decouples I/O voltage levels from VCC via the VIO pin, allowing interoperability with 1.8 V or 3.0 V host systems. Command execution-including Program Suspend/Resume and Erase Suspend/Resume-is fully software-controlled using JEDEC-standard sequences, with status reported via DQ7 polling, DQ6 toggle bits, or RY/BY# output.

Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL256S11TFI020 | Successor part; 65 nm process, 110 ns access, 100,000 cycles, same 56-pin TSOP package | Higher density efficiency and lower active current (20 mA vs. 25 mA); requires updated timing parameters in host driver | Preferred for new designs requiring extended lifecycle support and improved power efficiency |
| MX29GL256FHI-90G | Macronix equivalent; 90 ns access, 100,000 cycles, 56-pin TSOP, JEDEC command compatible but non-CFI | Lacks CFI and Secured Silicon Sector; no electronic serial number or password protection | Valid drop-in for basic read/write use cases where security and auto-configuration are not required |
Compared with S29GL256N11FAI020, the S29GL256S11TFI020 offers better longevity and lower power but requires firmware timing updates, while the MX29GL256FHI-90G provides cost-effective functional equivalence at the expense of security and system integration features.

Manufacturer
Cypress Semiconductor (now part of Infineon Technologies) is a fabless semiconductor company specializing in microcontrollers, connectivity solutions, and non-volatile memory for industrial, automotive, and consumer applications.
The S29GL-N family was designed for high-reliability embedded systems requiring deterministic boot performance, hardware-based security, and long-term data retention-targeting applications where firmware integrity and field upgradeability are critical.
FAQ
Is S29GL256N11FAI020 still in production?
No-Cypress officially retired the S29GL-N family in 2016 and recommends migration to the S29GL-S (e.g., S29GL256S) or S29GL-T series. Aetrix Electronics maintains limited legacy inventory with full traceability and supports last-time-buy programs for ongoing production continuity.
What does "11FAI020" in the part number indicate?
The suffix encodes package and temperature grade: "11" = 90 ns speed grade at regulated voltage; "F" = 56-pin TSOP; "A" = industrial temperature range (–40°C to +85°C); "I" = lead-free/RoHS compliant; "020" = date code (2012, week 20). This matches the datasheet's ordering information table.
Can S29GL256N11FAI020 operate with a 1.8 V host interface?
Yes-via the VIO pin. When VIO is supplied at 1.8 V, all address, control, and data inputs are referenced to that level, and outputs swing to 1.8 V logic thresholds. VCC remains at 3.0 V for core operation. This eliminates external level shifters in mixed-voltage systems.
Does this device support sector locking without software commands?
Yes-Persistent Sector Protection uses non-volatile lock bits that retain state across power cycles. Once enabled via command sequence, protected sectors remain locked until explicitly unlocked with the correct password or hardware reset sequence-no continuous software supervision required.
