Product details
Overview
S29GL064N11WEI039 from Infineon Technologies (formerly Cypress) is a 64 Mbit, 3.0 V single-power-supply MirrorBit Flash memory organized as 4,194,304 words (16-bit bus), featuring 90 ns access time, 100,000 erase cycles per sector, and 20-year data retention. It supports uniform sector architecture with 128 × 64 KB sectors and operates across VIO = 1.65–3.6 V for flexible I/O voltage control. Used in industrial control firmware storage and boot code retention where deterministic erase granularity and secure silicon identity are required.
For engineers reviewing the S29GL064N11WEI039 datasheet, S29GL064N11WEI039 pinout, S29GL064N11WEI039 application, or S29GL064N11WEI039 equivalent, key selection criteria include JEDEC-compliant command set compatibility, Secured Silicon Sector with factory-programmed 128-word ESN, hardware reset (RESET#) integration for boot recovery, and dual-mode write protection via WP#/ACC and persistent sector lock bits.
Technical Context
This device implements a 110 nm MirrorBit floating-gate architecture enabling simultaneous hot-hole erase and hot-electron programming. Its sector-based erase model isolates 64 KB blocks, allowing independent reprogramming without disturbing adjacent firmware regions. The VersatileI/O™ interface decouples VIO from VCC, supporting mixed-voltage host systems while maintaining full JEDEC software compatibility.
Hardware features include dedicated RY/BY# status output, DQ6/DQ7 polling support, and programmable Advanced Sector Protection with both Password and Persistent modes. The Secured Silicon Sector provides 256-byte factory-locked space accessible only via command sequence - used for immutable device identifiers or cryptographic keys in certified embedded platforms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (4,194,304 × 16-bit words) - defines maximum firmware image size and partitioning capability |
| Access Time | 90 ns at VCC = 2.7–3.6 V - enables direct execution from flash in real-time microcontroller boot paths |
| Erase Endurance | 100,000 cycles per sector - supports field-upgradable firmware with long service life in industrial PLCs |
| Data Retention | 20 years at 125°C - ensures reliability in automotive under-hood or telecom base station environments |

Pinout & Package
Package: 48-pin TSOP (Standard Thin Small Outline Package), lead-free, RoHS-compliant, body size 12 mm × 20 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A21 | Address Inputs | 22-bit address bus supporting full 4M-word addressing; A-1 multiplexed with DQ15 in byte mode |
| DQ0–DQ15 | Data/Address Multiplexed I/O | 16-bit bidirectional data bus; DQ15 functions as A-1 when BYTE# = low for 8-bit operation |

| OE# | Output Enable | Controls output buffer; allows shared bus arbitration without tri-state conflicts during read sequences |
| WE# | Write Enable | Initiates command latching or data writes; timing-critical for valid command sequence execution |
| WP#/ACC | Write Protect / Accelerated Program | Low = hardware sector lock; high + VHH = accelerated programming for production throughput |
| RESET# | Hardware Reset | Aborts ongoing erase/program and returns to read mode; synchronizes boot firmware reload on system reset |
| RY/BY# | Ready/Busy Output | Open-drain status signal indicating active programming/erase; eliminates need for polling overhead |
| BYTE# | Bus Width Select | Low = 8-bit mode (DQ0–DQ7 only); high = 16-bit mode - configures interface for legacy or compact controllers |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory-locked region with 8-word ESN - provides tamper-resistant device identity for secure boot validation |
| Program/Erase Suspend | Allows interrupting active program/erase to read or program other sectors - enables concurrent firmware update and runtime diagnostics |
| CFI Compliance | JEDEC JESD68-defined parameter tables - enables automatic flash detection and driver configuration in Linux U-Boot or RTOS BSPs |
| Unlock Bypass Mode | Reduces multi-word programming from 4 to 2 write cycles - cuts bootloader update time by ~35% in field deployments |
| Persistent Sector Protection | Non-volatile lock bits disable program/erase permanently until hardware reset - prevents accidental corruption of critical boot sectors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL064S11TFI020 | Same density and architecture but in 56-pin TSOP package with different thermal pad layout and 110 ns access time | Larger footprint and slower timing limit system clock scaling in space-constrained designs | Select when board layout requires 56-pin TSOP or thermal dissipation exceeds 48-pin limits |
| MX29GL640EHTI-90G | Micron device with identical 64 Mbit density, 90 ns access, but lacks Secured Silicon Sector and uses different CFI implementation | No factory-programmed ESN or persistent lock bits - unsuitable for secure boot or regulatory traceability | Choose only for cost-sensitive non-secure applications where CFI auto-detection is not required |
Compared with S29GL064S11TFI020, the S29GL064N11WEI039 offers tighter timing and smaller footprint; versus MX29GL640EHTI-90G, it delivers certified secure identity and robust sector protection essential for safety-critical firmware.

FAQ
Is S29GL064N11WEI039 compatible with legacy Cypress S29GL064N designs?
Yes - this part retains identical pinout, command set, timing parameters, and electrical characteristics as the original Cypress S29GL064N. Infineon maintains full backward compatibility including CFI structure, sector map, and unlock bypass behavior. No PCB or firmware changes are required for drop-in replacement in existing designs.
What is the function of the WP#/ACC pin in normal operation versus programming mode?
In normal operation, asserting WP# low protects the first or last sector from accidental writes or erases regardless of software protection settings. During programming, applying VHH (12 V) to ACC enables accelerated write cycles, reducing typical programming time by up to 40% - intended for high-throughput manufacturing but usable in-field with proper voltage generation.
How does the Secured Silicon Sector differ from standard protected sectors?
The Secured Silicon Sector is a dedicated 256-byte region programmed and locked at the factory with a unique 16-byte Electronic Serial Number. Unlike software-locked sectors, it cannot be erased or rewritten after locking - even with RESET# or power cycling. Access requires a specific command sequence, making it suitable for cryptographic key storage or regulatory device identification.
Can S29GL064N11WEI039 operate with VIO = 1.8 V while VCC = 3.3 V?
Yes - the VersatileI/O™ architecture explicitly supports independent VIO (1.65–3.6 V) and VCC (2.7–3.6 V) supplies. At VIO = 1.8 V, all input thresholds and output drive levels conform to 1.8 V logic families, enabling direct interfacing with low-voltage microcontrollers without external level shifters, while maintaining full 3.3 V core functionality.
