Product details
Overview
S29GL064N90FFI042 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 boot code storage in embedded systems requiring nonvolatile program storage with hardware reset and sector-level protection.
For engineers reviewing the S29GL064N90FFI042 datasheet, S29GL064N90FFI042 pinout, S29GL064N90FFI042 application, or S29GL064N90FFI042 equivalent, this device serves as a drop-in replacement for legacy parallel NOR Flash in industrial control firmware, automotive ECU boot memory, and network equipment BIOS storage - with verified JEDEC command compatibility, CFI support, and factory-locked Secured Silicon Sector.
Technical Context
This device uses 110 nm MirrorBit process technology to deliver high-density, single-supply NOR Flash operation at 3.0 V (2.7–3.6 V range), with VIO input enabling flexible I/O voltage control (1.65–3.6 V). Its architecture includes dedicated command registers, on-chip voltage generators for erase/program, and state machine control for autonomous sector erase and buffer write operations.
It supports both uniform and boot-sector configurations, though S29GL064N90FFI042 is a uniform-sector model. Hardware features include RESET#, RY/BY#, WP#/ACC, and BYTE# inputs; software features include Program/Erase Suspend/Resume, Password Sector Protection, and CFI-compliant identification - all implemented without external logic or voltage translators.
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 (VCC = 2.7–3.6 V, VIO = 2.7–3.6 V); meets timing requirements for 10 MHz+ parallel bus interfaces. |
| Erase Endurance | 100,000 cycles per sector; supports field firmware updates over 10+ years in deployed industrial devices. |
| Data Retention | 20 years at 125°C; validated for automotive under-hood and telecom base station environments. |
| Page Read Buffer | 8-word (16-byte) buffer with 25 ns page read time; reduces sequential read latency by >60% vs. random access. |
| Write Buffer | 16-word (32-byte) buffer; cuts multi-word programming time by eliminating per-word command overhead. |
| Supply Voltage | Single 3.0 V supply (2.7–3.6 V); eliminates need for dual-rail power design in host systems. |
Pinout & Package
Package: 48-pin TSOP (Type I, standard thin small outline package, 12 × 20 mm body, 0.5 mm pitch). Pinout validated per Infineon Document 001-98525 Rev. *B, Figure 1 (S29GL064N Models 03/04).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A21 | Address Inputs | 22-bit address bus supporting full 4M-word addressing; A-1 (DQ15/A-1) multiplexes most significant data bit or address bit. |
| DQ0–DQ15 | Data/Address Bus | 16-bit bidirectional data bus; DQ15 functions as A-1 during address latching, enabling 16-bit word mode only. |
| CE# | Chip Enable | Active-low chip select; must be asserted before WE# or OE# to enable device operation; controls power-down entry. |
| OE# | Output Enable | Active-low output gate; decouples data bus drivers during read cycles without affecting internal state. |
| WE# | Write Enable | Active-low write strobe; latches addresses and data for command execution, programming, or erase initiation. |
| RESET# | Hardware Reset | Active-low asynchronous reset; terminates ongoing erase/program and returns device to reading state instantly. |
| RY/BY# | Ready/Busy Output | Open-drain status signal; low during active erase/program; used for polling-free operation in real-time systems. |
| WP#/ACC | Write Protect / Accelerated Program | Input with dual function: low = hardware sector lock; high + VHH = accelerated programming (factory throughput mode). |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory-programmable and permanently lockable region for immutable serial numbers or cryptographic keys. |
| Advanced Sector Protection | Persistent and Password-based protection modes prevent unauthorized firmware modification without physical access or valid credentials. |
| Program/Erase Suspend | Allows host CPU to interrupt long-duration flash operations to service interrupts or read other memory regions - critical for real-time OS. |
| VersatileI/O™ Control | VIO pin sets all I/O thresholds independently of VCC (1.65–3.6 V), enabling direct interfacing with 1.8 V or 3.3 V controllers without level shifters. |
| CFI Compliance | Standardized query structure allows automatic detection and configuration by bootloader or BIOS - no hardcoded timing or vendor-specific code. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel NOR Flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL064S90TFI020 | Same density and speed, but 56-pin TSOP package; lacks Secured Silicon Sector; different AC timing specs (tACC = 90 ns, tCE = 90 ns, tOE = 25 ns). | Used in space-constrained router line cards where 56-pin footprint fits existing PCB layout but security features are secondary. | Select when board layout requires 56-pin TSOP and factory-locked serial number capability is not required. |
| MX29GL640EHT2I-90G | 64 Mbit, 90 ns, 48-pin TSOP; Macronix part with identical pinout and JEDEC command set; no Secured Silicon Sector; 10-year data retention (vs. 20 years). | Deployed in cost-sensitive industrial HMIs where firmware integrity is enforced via external crypto controller rather than on-die silicon. | Select for price-sensitive volume production where extended data retention and hardware-secured identity are not mandatory. |
Compared with S29GL064S90TFI020 and MX29GL640EHT2I-90G, the S29GL064N90FFI042 uniquely delivers factory-programmed Secured Silicon Sector, 20-year data retention, and VIO-controlled I/O compatibility - making it the only choice for applications requiring traceable, tamper-resistant boot memory in harsh thermal environments.

FAQ
Is S29GL064N90FFI042 pin-compatible with older S29GL064N variants?
Yes - S29GL064N90FFI042 uses the 48-pin TSOP package (TS048) with identical pinout, voltage ratings, and JEDEC command set as earlier S29GL064N revisions. The 'F' suffix denotes Infineon's post-acquisition branding; electrical and mechanical compatibility is fully maintained per Document 001-98525 Rev. *B.
Does this device support byte-wide operation?
No - S29GL064N90FFI042 is a 16-bit-only configuration. It does not support 8-bit mode via BYTE#; the BYTE# pin is present but unused in this variant. For 8/16-bit configurable operation, refer to S29GL064N models with 'T' or 'V' suffixes that explicitly list BYTE# functionality in ordering information.
What is the purpose of the WP#/ACC pin in normal operation?
In normal operation, WP#/ACC serves as hardware write protect: asserting low disables programming and erasure of the first or last sector regardless of software protection settings. When driven high with VHH (11–12 V), it enables accelerated programming for factory test throughput - a feature disabled in field use unless explicitly enabled via external circuitry.
How is the Secured Silicon Sector programmed and locked?
The Secured Silicon Sector is programmed using the Enter/Exit Secured Silicon Sector command sequence (documented in Section 10.4 of 001-98525 Rev. *B) and permanently locked via a dedicated lock bit. Once locked, no further writes or erases are possible - even with VPP applied. Factory programming and locking occur during wafer sort; customer locking is supported via command sequence.
