Product details
Overview
S29GL064N90BFI043 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 via JEDEC-standard command set for embedded boot code and firmware storage in industrial controllers.
For engineers reviewing the S29GL064N90BFI043 datasheet, S29GL064N90BFI043 pinout, S29GL064N90BFI043 application, or S29GL064N90BFI043 equivalent, key selection criteria include sector protection granularity (Persistent/Password), VIO voltage flexibility (1.65–3.6 V), page read/write buffer size (8-word / 16-byte read, 16-word / 32-byte write), and hardware reset (RESET#) and ready/busy (RY/BY#) signaling for real-time operation monitoring.
Technical Context
This device uses 110 nm MirrorBit process technology to enable simultaneous hot-hole assisted erase and hot-electron injection programming across full sectors. Its architecture integrates Secured Silicon Sector (128-word/256-byte factory- or customer-lockable region) and CFI-compliant interface for host system auto-configuration.
The VersatileI/O™ control decouples I/O voltage (VIO = 1.65–3.6 V) from core supply (VCC = 2.7–3.6 V), enabling interoperability with mixed-voltage microcontrollers. Erase suspend/resume and program suspend/resume allow concurrent background operations without halting host execution.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (4,194,304 × 16-bit words); enables storage of full bootloader + application firmware in single device |
| Access Time | 90 ns at VCC = 2.7–3.6 V; meets timing requirements for 11 MHz synchronous bus interfaces |
| Erase Endurance | 100,000 cycles per sector; supports field firmware updates over 10+ years in deployed equipment |
| 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; reduces sequential read latency by eliminating per-word address setup overhead |
| Write Buffer | 16-word (32-byte) buffer; cuts multi-word programming time by >60% vs. single-word writes |
| VIO Range | 1.65–3.6 V; allows direct interfacing with 1.8 V, 2.5 V, or 3.3 V logic without level shifters |
Pinout & Package
Package: 48-pin TSOP (Type I, standard thin small outline package, 12 × 20 mm body). Pinout conforms to JEDEC MO-142AC standard for 16-bit Flash memory.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A21 | Address inputs | 22-bit address bus supporting full 4M-word addressing; A-1 used as DQ15 during byte mode |
| DQ0–DQ15 | Data I/O bidirectional bus | 16-bit parallel interface; BYTE# input enables 8-bit mode using DQ0–DQ7 only |
| CE#, OE#, WE# | Chip, output, and write enable controls | Independent gating enables interleaved read/write and low-latency command execution |
| WP#/ACC | Write protect / accelerated program input | Hardware lock for first/last sector; high-voltage mode (VCC + 1.5 V) reduces programming time by ~40% |
| RY/BY# | Ready/Busy output | Active-low open-drain signal indicating active erase/program cycle; eliminates need for polling DQ7/DQ6 |
| RESET# | Hardware reset input | Aborts ongoing operation and returns device to read mode; synchronizes with system power-on reset |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory- or field-programmable locked region with 8-word ESN; prevents cloning of device identity or secure keys |
| Advanced Sector Protection | Persistent (non-volatile bit-based) and Password (16-byte encrypted) protection modes; blocks unauthorized firmware overwrite in production or field |
| Program/Erase Suspend | Pause active programming or erasing to service higher-priority reads from other sectors; essential for real-time OS interrupt handling |
| CFI Compliance | Standardized query structure enables automatic detection of geometry, timing, and protection features by host BIOS or bootloader |
| Unlock Bypass Mode | Two-cycle command sequence replaces four-cycle standard programming; reduces firmware update overhead by 50% in mass production |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the function of the WP#/ACC pin on S29GL064N90BFI043?
The WP#/ACC pin serves dual functions: as WP# (Write Protect), it permanently locks the first or last sector when pulled low, preventing accidental erase or program even during accelerated programming; as ACC (Accelerated Program), applying VCC + 1.5 V reduces typical programming time by ~40%, improving throughput in manufacturing test environments.
Does S29GL064N90BFI043 support 8-bit data bus operation?
Yes, the device supports 8-bit mode via the BYTE# input. When BYTE# is asserted low, only DQ0–DQ7 are active as an 8-bit data bus while DQ8–DQ15 are tri-stated; this enables compatibility with 8-bit microcontrollers without external data bus multiplexing logic.
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 user. Once secured, it cannot be erased or rewritten-even with unlock commands-and contains a unique 8-word Electronic Serial Number accessible only via specific command sequences, providing hardware-rooted device identity.
Can S29GL064N90BFI043 be used in systems with 1.8 V I/O voltage?
Yes, the device supports VIO = 1.65–3.6 V independently of VCC (2.7–3.6 V). With VIO = 1.8 V, all address, control, and data signals operate at 1.8 V logic levels, enabling direct connection to 1.8 V microcontrollers or FPGAs without level-shifting circuitry.
