Product details
Overview
S29GL064N90FFA023 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, 25 ns page read time, and uniform 64 KB sector architecture with 100,000 erase cycles per sector. It serves as nonvolatile program/data storage in embedded boot code, firmware update, and industrial control systems.
For engineers reviewing the S29GL064N90FFA023 datasheet, S29GL064N90FFA023 pinout, S29GL064N90FFA023 application, or S29GL064N90FFA023 equivalent, key selection criteria include JEDEC-compliant command set, Secured Silicon Sector with factory-programmed 128-word ESN, VIO-referenced VersatileI/O™, CFI compliance, and hardware reset (RESET#) for boot recovery.
Technical Context
This device implements a 110 nm MirrorBit floating-gate NOR Flash architecture with hot-electron injection programming and hot-hole assisted erase. It supports both uniform-sector (128 × 64 KB) and boot-sector (127 × 64 KB + 8 × 8 KB) configurations - the S29GL064N90FFA023 is a uniform-sector variant.
It features dual-voltage I/O control via VIO (1.65–3.6 V), independent of VCC (2.7–3.6 V), enabling mixed-voltage system interfacing. Status reporting uses DQ7 data polling, DQ6/DQ2 toggle bits, and RY/BY# output, with full support for Program/Erase Suspend & Resume operations across sectors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (4,194,304 × 16-bit words); enables full firmware image storage for mid-tier microcontrollers. |
| Access Time | 90 ns at VCC = 2.7–3.6 V, VIO = 2.7–3.6 V; ensures deterministic timing for real-time boot execution. |
| Sector Architecture | 128 uniform 64 KB sectors; simplifies partitioning for OTA updates and secure boot regions without boot-sector overhead. |
| Erase Endurance | 100,000 cycles per sector; supports field firmware upgrades over 10+ years in industrial deployments. |
| Data Retention | 20 years at 125 °C; validated for automotive under-hood and industrial high-temp environments. |
| Power Supply | Single 3.0 V supply (VCC = 2.7–3.6 V); eliminates need for separate VPP or charge pumps in host design. |
| VIO Range | 1.65–3.6 V; allows direct interface to 1.8 V or 3.3 V logic without level shifters. |
Pinout & Package
Package: 48-pin TSOP (Type 1, standard thin small outline package), 12 × 20 mm body, lead pitch 0.5 mm. Pin compatibility aligns with JEDEC MO-142AC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A21 | Address Inputs | 22-bit address bus supporting full 4M-word addressing; A-1 (DQ15) used for x16/x8 mode selection. |
| DQ0–DQ15 | Data/Address Bus (x16) | 16-bit bidirectional data bus; DQ15 doubles as A-1 for byte-mode configuration when BYTE# = LOW. |
| CE#, OE#, WE# | Chip/Output/Write Enable | Independent three-control gating enables concurrent memory access arbitration in multi-peripheral systems. |
| WP#/ACC | Write Protect / Accelerated Program | Hardware sector lock (WP#) and high-Vpp acceleration (ACC) share one pin; protects first/last sector during production programming. |
| RY/BY# | Ready/Busy Output | Active-low open-drain status signal indicating active erase/program; enables interrupt-driven host polling. |
| RESET# | Hardware Reset Input | Asynchronous active-low reset terminates all operations and restores device to read mode; ties directly to system reset rail. |
| VIO | I/O Voltage Reference | Defines logic thresholds for all address, control, and data pins independently of VCC; critical for mixed-voltage SoC interfaces. |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory-locked region with 8-word ESN; provides immutable device identity for secure boot and anti-cloning. |
| Advanced Sector Protection | Persistent and Password-based protection modes; prevents accidental or unauthorized firmware overwrite without explicit unlock sequence. |
| Program/Erase Suspend | Pause ongoing write/erase in one sector to read/program another; enables real-time diagnostics during firmware update. |
| CFI Compliance | Standardized query table at 0x0055, 0x0055, 0x00AA; allows automatic flash detection and driver configuration in Linux/U-Boot. |
| Unlock Bypass Mode | Reduces multi-word programming overhead from 4 to 2 write cycles; cuts flash programming time by ~30% in production line flashing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL064S90TFI020 | Same density and speed, but 56-pin TSOP package and boot-sector architecture (127 × 64 KB + 8 × 8 KB). | Requires different PCB layout and sector management logic; better suited for legacy BIOS-style boot code with dedicated boot blocks. | Select only if boot-sector partitioning is required and 56-pin footprint is available. |
| MX29GL640EHTI-90G | 64 Mbit, 90 ns, but uses 1.8 V core (VCC = 1.7–2.0 V) and lacks Secured Silicon Sector and CFI compliance. | Not suitable for secure boot or cross-platform driver reuse; limited to cost-sensitive consumer applications. | Choose only for low-power, non-secure applications where Infineon's security and ecosystem support are not needed. |
Compared with S29GL064S90TFI020 and MX29GL640EHTI-90G, the S29GL064N90FFA023 uniquely combines uniform-sector simplicity, factory-secured identity, and full CFI interoperability - making it optimal for new industrial and automotive designs requiring long-term firmware integrity and toolchain portability.

FAQ
Is S29GL064N90FFA023 compatible with legacy Cypress S29GL064N designs?
Yes - Infineon maintains full pin, command-set, and timing compatibility with original Cypress S29GL064N devices. The part number suffix "A023" denotes Infineon's updated packaging and traceability, with no functional or electrical changes. Existing PCB layouts, firmware drivers, and test procedures remain valid.
What is the role of the VIO pin, and can it be tied to VCC?
VIO sets input threshold voltage and output drive strength for all address, control, and data pins. It may be tied to VCC only if VCC falls within 1.65–3.6 V and matches the host interface voltage. For 1.8 V logic, VIO must be externally supplied at 1.8 V - tying it to 3.3 V VCC would violate input voltage limits and risk damage.
How does the Secured Silicon Sector differ from standard sector protection?
The Secured Silicon Sector is a dedicated 128-word (256-byte) region programmed and locked at the factory with a unique 8-word Electronic Serial Number. Unlike software-based sector locks, it cannot be unlocked or rewritten after locking - providing immutable device identity essential for secure boot and anti-counterfeiting.
Does S29GL064N90FFA023 support x8 data bus mode?
Yes - when BYTE# is driven LOW, the device operates in x8 mode using DQ0–DQ7 only, with A0–A20 addressing 8,388,608 bytes. This mode is fully supported in both read and program operations and retains all timing specifications except for page buffer size (reduced to 8 bytes).
