Product details
Overview
S29GL064N11FFIS43 from Infineon Technologies (formerly Cypress) is a 64 Mbit, 3.0 V single-power-supply MirrorBit Flash memory organized as 4,194,304 words (8,388,608 bytes), featuring 90 ns access time, 25 ns page read time, and uniform 128 × 64 KB sector architecture. It supports 16-bit data bus operation with BYTE# pin for optional 8-bit mode, and is used in embedded boot code storage, firmware update storage, and industrial controller nonvolatile program retention.
For engineers reviewing the S29GL064N11FFIS43 datasheet, S29GL064N11FFIS43 pinout, S29GL064N11FFIS43 application, or S29GL064N11FFIS43 equivalent, key selection criteria include JEDEC-compliant command set, Secured Silicon Sector with factory-programmed 128-word ESN, Advanced Sector Protection (Persistent and Password modes), CFI compliance, and support for Program/Erase Suspend & Resume functionality.
Technical Context
This device implements a 110 nm MirrorBit floating-gate NOR Flash architecture with hot-electron programming and hot-hole assisted erase. It uses separate CE#, WE#, and OE# controls, supports VIO-referenced I/O (1.65–3.6 V), and integrates hardware reset (RESET#), ready/busy signaling (RY/BY#), and write-protect acceleration via WP#/ACC pin.
The flash employs command-based operations compliant with JEDEC JESD21-C and includes CFI data structure for host auto-configuration. Sector erase granularity (64 KB uniform sectors), 100,000 erase cycles per sector, and 20-year data retention are guaranteed under specified operating conditions (VCC = 2.7–3.6 V, TA = –40°C to +85°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (4,194,304 × 16-bit words); enables full boot image + application firmware storage in single device |
| Access Time | 90 ns at VCC = 2.7–3.6 V; ensures deterministic timing for real-time microcontroller boot fetch |
| Page Read Time | 25 ns; reduces latency during sequential instruction fetch from page buffer |
| Erase Endurance | 100,000 cycles per sector; supports field firmware updates over product lifetime |
| Data Retention | 20 years at TA ≤ +85°C; guarantees long-term reliability without refresh |
| Supply Voltage | VCC = 2.7–3.6 V, VIO = 1.65–3.6 V; allows flexible I/O voltage scaling independent of core supply |
| Operating Temp | –40°C to +85°C; qualified for industrial-grade embedded control environments |
Pinout & Package
Package: 48-pin TSOP (Type I, standard thin small outline package, 12 × 20 mm body, 0.5 mm pitch). Pin compatibility confirmed per Infineon datasheet 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 multiplexed with DQ15 in x16 mode |
| DQ0–DQ15 | Data I/O (x16) | 16-bit bidirectional data bus; BYTE# selects x8/x16 mode; DQ15 doubles as A-1 in x16 configuration |
| CE# | Chip Enable | Active-low chip select; enables internal logic only when asserted; critical for multi-device memory mapping |
| WE# | Write Enable | Controls write latching; low during command/data writes; must meet tWP timing for reliable command execution |
| OE# | Output Enable | Enables output drivers during read; decouples read timing from address setup for burst access |
| WP#/ACC | Write Protect / Accelerated Program | Low = hardware sector protection (first/last sector); high + VHH = accelerated programming for production throughput |
| RY/BY# | Ready/Busy Output | Open-drain active-low status signal; indicates ongoing program/erase; eliminates need for polling overhead |
| RESET# | Hardware Reset | Asynchronous active-low reset; terminates all operations and returns device to read mode; ties to system reset rail |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory-locked region with 16-byte ESN; provides immutable device identity for secure boot and licensing |
| Advanced Sector Protection | Persistent (bit-lockable) and Password (16-byte key) modes; prevents unauthorized firmware overwrite without physical or cryptographic access |
| Program/Erase Suspend & Resume | Allows interrupting active program/erase to service higher-priority reads/writes elsewhere; essential for real-time multitasking systems |
| CFI Compliance | Standardized parameter table accessible via command; enables automatic detection and configuration by bootloader/host OS |
| Unlock Bypass Mode | Reduces multi-word programming overhead from 4 to 2 write cycles per word; improves firmware update speed in production and field |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL064S11FFIV10 | Same density and pinout; 110 ns access time (vs. 90 ns); uses 90 nm process (vs. 110 nm); no Secured Silicon Sector | Lacks factory-programmed ESN and persistent lock register; unsuitable for secure boot or device authentication use cases | Select when cost sensitivity outweighs security and performance; verify timing margins in high-speed boot paths |
| MX29GL640EBTI-90G | 64 Mbit, 90 ns, 3 V; Macronix part with identical TSOP-48 footprint; supports CFI but lacks Password Sector Protection and Unlock Bypass | No hardware-accelerated programming (no ACC input); no suspend/resume capability; lower endurance (100K vs. same, but unverified field data) | Choose for drop-in replacement where advanced protection and suspend features are unused; confirm RESET# behavior matches |
Compared with S29GL064S11FFIV10 and MX29GL640EBTI-90G, the S29GL064N11FFIS43 uniquely delivers factory-secured identity, dual-mode sector protection, and suspend-enabled real-time operation-making it the only option for safety-critical or field-upgradable embedded systems requiring both performance and tamper resistance.

FAQ
What is the function of the WP#/ACC pin on S29GL064N11FFIS43?
The WP#/ACC pin serves two distinct roles: when driven low, it hardware-protects the first or last sector regardless of software protection settings; when driven high with an elevated voltage (VHH ≈ 11.5 V), it accelerates programming time during manufacturing. This dual function enables both field-level security and production-line throughput optimization without external circuitry.
Does S29GL064N11FFIS43 support true 8-bit data bus operation?
Yes-it supports true 8-bit mode via the BYTE# pin. When BYTE# is low, DQ0–DQ7 operate as an 8-bit data bus with A0–A20 addressing; when high, it operates in full 16-bit mode (DQ0–DQ15) with A0–A21. This is not multiplexed emulation: the device internally routes separate 8-bit paths and meets all AC timing specs in both configurations per datasheet Section 8.1.
How is the Secured Silicon Sector programmed and locked?
The Secured Silicon Sector is pre-programmed at the factory with a unique 16-byte Electronic Serial Number and can be customer-locked using the "Program Secured Silicon Sector" command sequence (Section 10.4 of datasheet 001-98525). Once locked via the PPB (Persistent Protection Bit), the sector becomes permanently read-only-even under VCC brownout or reset-and cannot be erased or rewritten.
Can S29GL064N11FFIS43 be used in systems with 1.8 V I/O interfaces?
No-its VIO range is strictly 1.65 V to 3.6 V, but operation below 2.7 V is only supported in standby and low-power modes, not in active read/write. For 1.8 V systems, level-shifting is required on DQ, CE#, WE#, OE#, and WP#/ACC lines; the device does not tolerate 1.8 V as VIO during command execution or data transfer per DC Characteristics Table (Section 13).
