Product details
Overview
S29GL064N90TFI023 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 implements uniform sector architecture with 128 × 64 KB sectors and supports in-system programming and sector-level erase for embedded boot code and firmware storage in industrial controllers.
For engineers reviewing the S29GL064N90TFI023 datasheet, S29GL064N90TFI023 pinout, S29GL064N90TFI023 application, or S29GL064N90TFI023 equivalent, key selection criteria include JEDEC-compliant command set, Secured Silicon Sector with factory-programmed 128-word ESN, VIO-referenced VersatileI/O™, CFI compliance for host auto-configuration, and hardware reset (RESET#) with RY/BY# status signaling.
Technical Context
This device uses 110 nm MirrorBit process technology to enable simultaneous hot-hole assisted erase and hot-electron injection programming across 64 MB of NOR Flash. Its architecture includes dedicated sector switches, on-chip voltage generators for erase/program, and state control logic that interprets JEDEC-standard command sequences written via standard microprocessor timing.
The device supports dual-bus operation: 16-bit wide data bus only (no BYTE# function) in this variant, with separate CE#, WE#, and OE# controls. VIO input (1.65–3.6 V) sets all I/O voltage thresholds, enabling interoperability with mixed-voltage host systems while maintaining full read/write functionality at VCC = 2.7–3.6 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (4,194,304 × 16-bit words); enables storage of full boot firmware images for ARM Cortex-M or RISC-V MCUs. |
| Access Time | 90 ns (VCC = 2.7–3.6 V, VIO = 2.7–3.6 V); ensures deterministic instruction fetch latency in real-time embedded systems. |
| Erase Endurance | 100,000 cycles per sector; supports field firmware updates over 10+ years in industrial gateways. |
| Data Retention | 20 years at 125°C; validated for automotive under-hood and industrial high-temp environments. |
| Page Read Buffer | 8-word (16-byte) buffer with 25 ns page access time; accelerates sequential code execution from linear address space. |
| Write Buffer | 16-word (32-byte) buffer; reduces multi-word programming overhead by batching writes before internal commit. |
| Secured Silicon Sector | 128-word (256-byte) factory-lockable region with 8-word ESN; provides immutable device identity for secure boot root-of-trust. |
Pinout & Package
Package: 48-pin TSOP (Type I, standard thin small outline package, 12 × 20 mm body, 0.5 mm pitch). Pin compatibility follows JEDEC MO-141AC standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A21 | Address Inputs | 22-bit address bus supporting full 4M-word addressing; A21 selects upper/lower 32 MB in 64 MB map. |
| DQ0–DQ15 | Data/Address Bus (multiplexed) | 16-bit bidirectional data bus; DQ15 also functions as A−1 for extended addressing in some modes. |
| CE# | Chip Enable | Active-low chip select; device enters standby when deasserted, reducing current to ≤1 µA. |
| WE# | Write Enable | Controls write latching; initiates command loading or data programming when asserted with valid address/data. |
| OE# | Output Enable | Enables output drivers during read; allows shared bus operation with other peripherals without tristate conflicts. |
| RESET# | Hardware Reset | Asynchronous active-low reset; terminates ongoing erase/program and returns device to read mode within 100 ns. |
| RY/BY# | Ready/Busy Output | Open-drain status signal; low during erase/program, high when ready-enables interrupt-driven host polling. |
| WP#/ACC | Write Protect / Accelerated Program | Low = hardware sector protection (first/last sector); high + VHH = accelerated programming for production throughput. |
Key Features
| Feature | Design Value |
|---|---|
| CFI Compliance | Host reads device geometry, timings, and command set from on-chip CFI query table-enabling automatic driver initialization without hard-coded parameters. |
| Program/Erase Suspend | Pause active programming or erasing to service higher-priority reads from other sectors-critical for real-time OS task scheduling. |
| Advanced Sector Protection | Persistent (PPB) and Password-based protection modes allow selective lockdown of boot sectors against accidental overwrite or malicious tampering. |
| VersatileI/O™ Control | VIO pin sets all I/O voltage thresholds independently of VCC, permitting direct interfacing with 1.8 V or 3.3 V logic without level shifters. |
| Unlock Bypass Mode | Reduces multi-word programming from 4-cycle to 2-cycle command sequence-cutting firmware update time by ~40% in host-controlled field upgrades. |
Applications
| Industrial PLC Firmware Storage | Automotive Body Control Module (BCM) |

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 boot-sector architecture (127 × 64 KB + 8 × 8 KB boot sectors); different sector map and CFI descriptor. | Optimized for x86 BIOS or ARM bootROM where top/bottom 64 KB sectors require independent protection. | Select when boot code resides in dedicated small sectors and requires asymmetric protection granularity. |
| MX29GL640EHT2I-90G | 64 Mbit, 90 ns, but uses Macronix's MXSMIO interface; no CFI support; different command set and sector lock mechanism. | Lacks Secured Silicon Sector and Password Protection; requires custom driver adaptation. | Choose only if legacy system already uses MX29GL-series drivers and CFI auto-detection is not required. |
Compared with S29GL064S90TFI020, the S29GL064N90TFI023 offers uniform sector layout ideal for generic firmware partitioning, while MX29GL640EHT2I-90G trades security features for lower cost in non-secure consumer applications-making the N-variant optimal for new designs needing CFI, ESN, and persistent protection.

FAQ
Is S29GL064N90TFI023 compatible with legacy Cypress S29GL064N designs?
Yes. This part retains identical pinout, command set, timing specifications, and electrical characteristics as the original Cypress S29GL064N. Infineon maintains full backward compatibility-including identical AC/DC parameters, CFI structure, and sector protection behavior-ensuring drop-in replacement without design change or qualification retesting.
What is the function of the WP#/ACC pin in normal operation versus accelerated programming?
In normal operation, asserting WP# low protects the first or last sector from program/erase regardless of software protection settings. During accelerated programming, applying VHH (≈9 V) to ACC enables faster internal charge pump operation, cutting typical programming time by 30–50%-a feature used exclusively in manufacturing test and burn-in, not in-field operation.
Does S29GL064N90TFI023 support byte-wide data access?
No. This specific variant (indicated by 'N' suffix and 48-pin TSOP packaging) supports 16-bit word-wide operation only. The BYTE# pin is not implemented; DQ0–DQ15 operate exclusively as a 16-bit bus. For 8/16-bit configurable operation, refer to S29GL064P or S29GL064R variants with 56-pin TSOP or BGA packages.
How is the Secured Silicon Sector protected and accessed?
The Secured Silicon Sector is a dedicated 128-word (256-byte) region pre-programmed with an 8-word electronic serial number (ESN) at the factory. Access requires issuing the Enter Secured Silicon Sector command (0x80 → 0x90), followed by standard read commands. Once locked via PPB or password, it becomes permanently read-only and immune to erase or program operations.
