Product details
Overview
S29GL064N90FFA040 from Cypress Semiconductor is a 64 Mbit (8 MB), 3.0 V single-power-supply MirrorBit Flash memory organized as 4,194,304 × 16-bit words, featuring 90 ns access time, 25 ns page read time, and uniform 64 KB sector architecture (128 sectors). It supports 16-bit data bus operation with BYTE# control for optional 8-bit mode and integrates Secured Silicon Sector with factory-programmed 128-word Electronic Serial Number - used in industrial control firmware storage and boot code retention.
For engineers reviewing the S29GL064N90FFA040 datasheet, S29GL064N90FFA040 pinout, S29GL064N90FFA040 application, or S29GL064N90FFA040 equivalent, key selection criteria include JEDEC-compliant command set, hardware reset (RESET#) and ready/busy (RY/BY#) signaling, VIO-controlled I/O voltage range (1.65–3.6 V), and persistent/password-based sector protection for secure firmware updates.
Technical Context
This device implements a command-latched, state-machine-driven architecture with hot-electron programming and hot-hole erase mechanisms. It uses a 110 nm MirrorBit process and supports CFI (Common Flash Interface) for automatic device identification and configuration by host systems.
It features dual-mode sector protection (Persistent and Password), Erase/Program Suspend & Resume, and Unlock Bypass programming to reduce multi-word write overhead. The VIO input independently sets I/O voltage levels, decoupling interface logic from core VCC (2.7–3.6 V), enabling mixed-voltage system integration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (8,388,608 bytes), organized as 4,194,304 × 16-bit words - defines maximum firmware image size and address space required. |
| Access Time | 90 ns (VCC = 2.7–3.6 V, VIO = 2.7–3.6 V) - determines minimum CPU wait-state timing for random reads in embedded boot loaders. |
| Page Read Time | 25 ns - enables high-throughput sequential instruction fetch from 8-word (16-byte) internal buffer during code execution. |
| Erase Endurance | 100,000 cycles per sector - supports field firmware update cycles over 10+ years in industrial gateways. |
| Data Retention | 20 years at 125°C - ensures long-term reliability of calibration data and security keys in automotive ECUs. |
| Supply Voltage | VCC = 2.7–3.6 V; VIO = 1.65–3.6 V - allows direct interfacing with 1.8 V or 3.3 V microcontrollers without level shifters. |
| Package | 48-ball fine-pitch BGA (VBK048, 8.15 × 6.15 mm) - provides compact footprint for space-constrained IoT edge nodes. |
Pinout & Package
Package: 48-ball fine-pitch BGA (VBK048), RoHS-compliant, 0.5 mm ball pitch, 8.15 × 6.15 mm body size.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A21 | Address Inputs | 22-bit address bus supporting full 4 MB word addressing; A-1 (DQ15) multiplexed as MSB for 16-bit mode. |
| DQ0–DQ15 | Bi-directional Data I/O | 16-bit parallel data path; DQ15 doubles as A-1 in word mode; supports byte-wide access via BYTE# control. |
| CE#, OE#, WE# | Chip/Output/Write Enable | Independent active-low controls enable concurrent memory mapping, read gating, and write initiation without bus contention. |
| RESET# | Hardware Reset Input | Asynchronous hard reset that terminates ongoing erase/program and returns device to read mode - critical for safe boot recovery. |
| RY/BY# | Ready/Busy Output | Open-drain status signal indicating active programming/erase; enables polling-free interrupt-driven firmware update flow. |
| WP#/ACC | Write Protect / Accelerated Program | Low-active WP# protects first/last sector; high-voltage ACC mode reduces program time during manufacturing or field reflash. |
| VIO | I/O Supply Reference | Sets input threshold and output drive strength independently from VCC - essential for mixed-voltage SoC interfaces. |
Key Features
| Feature | Design Value |
|---|---|

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 and permanent lock capability. | Used in cost-sensitive consumer electronics where device identity and cryptographic binding are not required. | Select when board layout favors TSOP, BGA assembly is unavailable, and secure identity features are unnecessary. |
| MX29GL640EHT2I-90G | 64 Mbit, 90 ns, 48-ball BGA, but requires separate 12 V for sector protection unlock - no VIO flexibility or CFI compliance. | Deployed in legacy industrial HMIs with fixed 12 V rails and non-standard flash drivers. | Choose only if existing design relies on 12 V protection scheme and cannot adopt Cypress's VIO-based I/O scaling. |
Compared with S29GL064S90TFI020 and MX29GL640EHT2I-90G, the S29GL064N90FFA040 uniquely combines BGA miniaturization, VIO voltage independence, CFI standardization, and factory-provisioned Secured Silicon - making it optimal for next-generation secure, mixed-voltage embedded systems requiring long-term firmware integrity.

FAQ
What is the function of the VIO pin on the S29GL064N90FFA040?
The VIO pin sets the voltage reference for all input thresholds and output drive strength, independent of VCC. It accepts 1.65–3.6 V, enabling direct interface with 1.8 V or 3.3 V host processors without external level shifters. This decoupling simplifies mixed-voltage board design and improves noise immunity during signal transitions.
How does the Secured Silicon Sector differ from standard flash sectors?
The Secured Silicon Sector is a dedicated 128-word (256-byte) region pre-programmed at the factory with an 8-word Electronic Serial Number and permanently locked via fuse or one-time-programmable bits. Unlike standard sectors, it cannot be erased or rewritten after locking - ensuring immutable device identity and secure key storage for cryptographic operations.
Can the S29GL064N90FFA040 operate in 8-bit data bus mode?
Yes, when the BYTE# pin is asserted low, the device operates in 8-bit mode using DQ0–DQ7 only, with A0–A20 addressing bytes. This mode is fully supported in both read and write operations and maintains full command set compatibility, enabling use with 8-bit microcontrollers or legacy bus architectures.
What is the purpose of the WP#/ACC pin in accelerated programming mode?
When a high voltage (typically 5.5 V) is applied to WP#/ACC, the device enters accelerated programming mode, reducing individual word programming time by ~30%. This feature is intended for high-throughput manufacturing but can also be used in-field for faster firmware patches - while still preserving hardware write protection of the first/last sector.
