Product details
Overview
S29GL064N90FAI040 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 - deployed in industrial embedded boot code storage and firmware update systems.
For engineers reviewing the S29GL064N90FAI040 datasheet, S29GL064N90FAI040 pinout, S29GL064N90FAI040 application, or S29GL064N90FAI040 equivalent, key selection criteria include sector protection granularity (128-word Secured Silicon Sector), CFI compliance for host auto-configuration, Erase/Program Suspend capability, and TSOP-48 package compatibility with legacy PCB footprints.
Technical Context
This device implements a command-set-compatible JEDEC-standard Flash interface with hardware reset (RESET#), Ready/Busy# status signaling, and dual-mode write protection via WP#/ACC input. Its 110 nm MirrorBit process enables hot-hole erase and hot-electron programming, supporting both byte/word configuration (via BYTE#) and page-mode reads (8-word buffer).
It integrates Advanced Sector Protection with Persistent and Password-based modes, plus CFI-compliant identification registers. The VIO-referenced VersatileI/O™ allows independent I/O voltage scaling down to 1.65 V while maintaining full functionality at VCC = 2.7–3.6 V - critical for mixed-voltage system integration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (4,194,304 × 16-bit words); enables full boot firmware + parameter storage in single device |
| Access Time | 90 ns at VCC = 2.7–3.6 V; meets real-time boot latency requirements in industrial controllers |
| Erase Endurance | 100,000 cycles per sector; supports field firmware updates over 10+ years of operation |
| Data Retention | 20 years at 125°C; validated for automotive under-hood and industrial high-temp environments |
| Supply Voltage | VCC = 2.7–3.6 V, VIO = 1.65–3.6 V; decouples I/O logic from core voltage for mixed-signal SoC interfacing |
| Page Read Buffer | 8-word (16-byte); reduces sequential read latency by eliminating address setup overhead per word |
| Write Buffer Size | 16-word (32-byte); cuts multi-word programming time by >40% vs. single-word writes |
Pinout & Package
Package: 48-pin TSOP (Standard Thin Small Outline Package), 12 × 20 mm body, lead pitch 0.5 mm - compatible with JEDEC MO-142AC standard and automated SMT assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A21 | Address Inputs | 22-bit address bus supporting full 4M-word addressing; A-1 used for DQ15 multiplexing in x16 mode |
| DQ0–DQ15 | Data I/O Bus | 16-bit bidirectional data path; DQ15 doubles as A-1 for x16 configuration; supports BYTE#-controlled x8 mode |
| CE#, OE#, WE# | Chip/Output/Write Enable | Independent control enables interleaved read/write operations and eliminates bus contention during memory access |
| WP#/ACC | Write Protect / Accelerated Program | Logic-low assertion protects first/last sector; high-voltage mode (VHH) reduces programming time by ~50% in production |
| RY/BY# | Ready/Busy Output | Active-low open-drain signal indicates active erase/program cycle completion - eliminates polling overhead |
| RESET# | Hardware Reset Input | Asynchronous reset terminates ongoing operations and restores device to known state; ties directly to system reset rail |
| VIO | I/O Supply Reference | Defines logic threshold for all address/control/data pins; enables interoperability with 1.8 V or 3.3 V host interfaces |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory- or customer-lockable region with 8-word ESN; provides immutable device identity for secure boot verification |
| Erase Suspend/Resume | Pauses background sector erase to allow immediate read/program of other sectors - essential for real-time firmware patching |
| Unlock Bypass Mode | Reduces multi-word programming command overhead from 4 to 2 write cycles; improves throughput by ~35% in mass production |
| CFI Compliance | Standardized query structure enables automatic detection and configuration by host BIOS/bootloader without hard-coded drivers |
| Persistent Sector Protection | Non-volatile lock bits disable program/erase in selected sectors without requiring external voltage; replaces obsolete 12 V protection schemes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL064S90TFI010 | Same density and speed, but 56-pin TSOP package; lacks Secured Silicon Sector and Password Protection | Targeted at cost-sensitive consumer electronics where secure identity and sector-level password enforcement are not required | Select when board layout accommodates larger TSOP-56 footprint and security features are omitted from system architecture |
| MX29GL640EHTI-90G | 64 Mbit, 90 ns, but uses 130 nm process; no CFI support; only uniform sector architecture (no boot sectors) | Used in legacy telecom infrastructure where host firmware lacks CFI auto-detection and boot-sector flexibility is unnecessary | Choose only if existing design relies on non-CFI command sets and does not require suspend/resume or secured silicon functions |
Compared with S29GL064S90TFI010 and MX29GL640EHTI-90G, the S29GL064N90FAI040 uniquely combines CFI compliance, Erase/Program Suspend, and factory-programmable Secured Silicon Sector - making it the sole option for secure, upgradable boot memory in safety-critical industrial and automotive platforms.

FAQ
What package type is S29GL064N90FAI040?
S29GL064N90FAI040 uses a 48-pin TSOP (Thin Small Outline Package) with 12 × 20 mm body and 0.5 mm lead pitch, conforming to JEDEC MO-142AC. It is not pin-compatible with 56-pin or BGA variants of the same family - mechanical and thermal handling requires adherence to Cypress/Infineon special packaging guidelines for molded packages.
Does S29GL064N90FAI040 support 8-bit data bus operation?
Yes, it supports 8-bit operation via the BYTE# input: when BYTE# is asserted low, the device operates in x8 mode using DQ0–DQ7 only, with A0–A20 providing 21-bit addressing. This mode is fully supported in both read and write operations and maintains full command set compatibility including CFI queries and sector protection.
How is the Secured Silicon Sector programmed and locked?
The Secured Silicon Sector is programmed using the Enter Secured Silicon Sector command sequence (0x00 → 0x00 → 0x00 → 0x00), then written like normal flash. Locking is performed via the Lock Secured Silicon Sector command (0x00 → 0x00 → 0x00 → 0x29). Once locked, no further writes or erases are possible - even with VPP applied - and the 8-word ESN remains permanently readable.
Can Erase Suspend be used during Chip Erase?
No. Erase Suspend is supported only for Sector Erase operations, not Chip Erase. During a Chip Erase command sequence, the device does not respond to Erase Suspend commands; attempting to issue one has no effect. Host systems must complete chip erase before initiating any other operation - this is explicitly defined in the AC characteristics table and command definitions section of the datasheet.
