Product details
Overview
S29GL064N90FFI043 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 microcontroller systems requiring nonvolatile program storage with hardware reset recovery.
For engineers reviewing the S29GL064N90FFI043 datasheet, S29GL064N90FFI043 pinout, S29GL064N90FFI043 application, or S29GL064N90FFI043 equivalent, key selection criteria include JEDEC-compliant command set, VIO-referenced VersatileI/O™ operation (1.65–3.6 V), Secured Silicon Sector with factory-programmed 128-word ESN, and support for Program/Erase Suspend & Resume in real-time firmware update scenarios.
Technical Context
This device uses 110 nm MirrorBit process technology to enable hot-hole assisted erase and hot-electron injection programming. Its architecture includes separate CE#, WE#, and OE# controls, dual-mode 16/8-bit data bus via BYTE# input, and a dedicated RY/BY# output for cycle completion detection.
The flash integrates CFI (Common Flash Interface) for host auto-identification, Advanced Sector Protection with Persistent and Password modes, and hardware-level write protection via WP#/ACC pin-enabling accelerated programming and first/last sector lock independent of software protection settings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (4,194,304 × 16-bit words); enables full boot firmware + application image storage in resource-constrained embedded hosts. |
| Access Time | 90 ns at VCC = 2.7–3.6 V; ensures deterministic timing for CPU fetch cycles without wait states in 3.0 V systems. |
| Erase Endurance | 100,000 cycles per sector; supports field firmware updates over product lifetime in industrial controllers. |
| Data Retention | 20 years typical; guarantees long-term reliability for unpowered storage in automotive ECUs and medical devices. |
| Supply Voltage | VCC = 2.7–3.6 V, VIO = 1.65–3.6 V; allows flexible I/O voltage scaling to match host processor logic levels. |
| Page Read Buffer | 8-word (16-byte); reduces sequential read latency by prefetching adjacent data during instruction fetch. |
| Write Buffer Size | 16-word (32-byte); cuts multi-word programming time by batching writes and minimizing command overhead. |
Pinout & Package
Package: 48-pin TSOP (Type I, standard thin small outline package), footprint-compatible with JEDEC MO-142AC, body size 18.4 mm × 12.0 mm × 1.2 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A21 | Address Inputs | 22-bit address bus supporting full 4M-word addressing; A-1 (DQ15) used as MSB in x16 mode. |
| DQ0–DQ15 | Data I/O Bus | 16-bit bidirectional data path; operates as 8-bit when BYTE# = low (x8 mode). |
| 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 sequences and data programming on falling edge. |
| OE# | Output Enable | Enables output drivers during read; decouples read timing from CE# for flexible bus arbitration. |
| WP#/ACC | Write Protect / Accelerated Program | Low = sector lock; high-voltage = faster programming; protects first/last sector regardless of software settings. |
| RY/BY# | Ready/Busy Output | Open-drain status signal; low = operation in progress, high = ready for next command. |
| RESET# | Hardware Reset | Aborts active erase/program and resets internal state; ties directly to system reset for boot recovery. |
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. |
| Program/Erase Suspend & Resume | Allows interruption of active programming/erasing to service higher-priority reads elsewhere; essential for real-time OS firmware updates. |
| VersatileI/O™ Control | VIO-referenced inputs/outputs (1.65–3.6 V); eliminates level shifters when interfacing with mixed-voltage SoCs or FPGAs. |
| CFI Compliance | JEDEC-standard Common Flash Interface; enables automatic device detection and parameter readout by bootloader without hard-coded offsets. |
| Unlock Bypass Mode | Reduces multi-word programming from 4 to 2 write cycles; improves throughput during production programming and field OTA patching. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL064S90TFI020 | Same density and 90 ns speed, but 56-pin TSOP package and no Secured Silicon Sector. | Lacks factory-programmed ESN; unsuitable for secure boot or device authentication use cases. | Select when cost-sensitive industrial control designs require identical timing but omit security features. |
| MX29GL640EHTI-90G | 64 Mbit, 90 ns, 48-pin TSOP, but uses standard NOR architecture (not MirrorBit) and lacks CFI compliance. | No auto-identification capability; requires hardcoded driver initialization and lacks password protection. | Choose only for legacy systems where CFI and advanced sector protection are not required. |
Compared with S29GL064S90TFI020 and MX29GL640EHTI-90G, the S29GL064N90FFI043 uniquely delivers factory-secured identity, CFI-based portability, and suspend/resume functionality-making it the only option for secure, upgradable, and host-agnostic embedded boot memory.

FAQ
What is the function of the WP#/ACC pin on S29GL064N90FFI043?
The WP#/ACC pin serves dual roles: when driven low, it permanently protects the first or last sector from program/erase operations; when driven high with 5.5 V (±0.5 V), it accelerates programming time by enabling higher internal PGM voltage. This dual functionality supports both field-level write protection and factory high-throughput programming without external circuitry.
Does S29GL064N90FFI043 support 8-bit data bus operation?
Yes, it supports 8-bit operation via the BYTE# input: when BYTE# is low, DQ0–DQ7 function as an 8-bit data bus with DQ8–DQ15 disabled; when BYTE# is high, the full 16-bit bus is active. This mode is fully compatible with x8-oriented microcontrollers and reduces PCB routing complexity in space-constrained designs.
How does the Secured Silicon Sector differ from standard flash sectors?
The Secured Silicon Sector is a dedicated 128-word (256-byte) region that can be permanently locked at factory or by the customer. Once secured, no further writes or erases are possible-even with valid unlock commands. It contains a unique 8-word Electronic Serial Number and is used for immutable device identification, secure boot keys, or calibration constants in regulated industries.
Can S29GL064N90FFI043 be used in systems with 1.8 V I/O interfaces?
Yes, provided VIO is supplied at 1.8 V (within 1.65–3.6 V range) and VCC remains at 2.7–3.6 V. All address, control, and data pins reference VIO, enabling direct connection to 1.8 V FPGAs or ASICs without level shifters-while maintaining full 3.0 V core operation for optimal endurance and retention performance.
