Product details

Overview

S29GL064N90TFI040H 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 JEDEC-compliant command set, CFI interface, and operates across VIO = 1.65–3.6 V for flexible I/O voltage control - deployed in industrial embedded boot code storage and firmware update modules.

For engineers reviewing the S29GL064N90TFI040H datasheet, S29GL064N90TFI040H pinout, S29GL064N90TFI040H application, or S29GL064N90TFI040H equivalent, key selection criteria include sector protection mode (Persistent/Password), Secured Silicon Sector availability, TSOP-48 package compatibility, and hardware reset (RESET#) and ready/busy (RY/BY#) signaling for real-time operation monitoring.

Technical Context

This device implements a 16-bit parallel NOR Flash architecture with hot-electron programming and hot-hole erase mechanisms, enabling 100,000 erase cycles per sector and 20-year data retention. Its command-set compatibility with JEDEC JESD21-C ensures interoperability with legacy host controllers without firmware modification.

The VersatileI/O™ control decouples I/O voltage (VIO) from core supply (VCC), allowing mixed-voltage system integration while maintaining full 16-bit bus operation. Hardware features include WP#/ACC-accelerated programming, RY/BY# status output, and RESET#-initiated abort/recovery - critical for deterministic boot sequencing in safety-critical firmware storage.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NOR Flash memory applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL064S90TFI020	Same density and speed, but uses 56-pin TSOP package and includes boot-sector architecture (8 × 8 KB + 127 × 64 KB)	Optimized for legacy BIOS partitioning where top/bottom boot sectors are required	Select when boot code must reside in dedicated small sectors; not pin-compatible with TSOP-48 layout
MX29GL640EHTI-90G	64 Mbit, 90 ns, but lacks Secured Silicon Sector and Password Protection; uses different command set (non-CFI)	Lower-cost alternative where cryptographic security and field-upgrade protection are not required	Choose only for cost-sensitive consumer applications with static firmware; requires custom driver development

Compared with S29GL064S90TFI020 and MX29GL640EHTI-90G, the S29GL064N90TFI040H uniquely combines uniform-sector flexibility, factory-programmed secure identity, and full CFI compliance - making it optimal for industrial OEMs requiring both field-upgrade capability and audit-ready firmware integrity.

FAQ

What is the function of the BYTE# pin on S29GL064N90TFI040H?

The BYTE# pin configures the device's data bus width: when pulled high, it enables full 16-bit (x16) operation using DQ0–DQ15; when pulled low, it selects 8-bit (x8) mode where only DQ0–DQ7 are active and DQ8–DQ15 become high-impedance. This allows backward compatibility with legacy 8-bit microcontrollers without redesigning the PCB layout.

Does S29GL064N90TFI040H support hardware reset during active erase or program operations?

Yes - asserting RESET# asynchronously terminates any ongoing erase or program operation, clears internal state machines, and returns the device to read mode within 100 ns. The device retains all previously programmed data, and no sector corruption occurs. This behavior is guaranteed per datasheet Section 8.6 and is essential for fail-safe recovery in safety-critical systems.

How does the Secured Silicon Sector differ from standard flash sectors?

The Secured Silicon Sector is a dedicated 256-byte region (128 words) pre-programmed at the factory with a unique 16-byte Electronic Serial Number and permanently locked via fuse or OTP mechanism. Unlike standard sectors, it cannot be erased or rewritten after initial lock - even with elevated VPP or command sequences - ensuring immutable device identification for traceability and anti-counterfeiting.

Can S29GL064N90TFI040H operate with VIO = 1.8 V while VCC = 3.3 V?

Yes - the VersatileI/O™ architecture explicitly supports independent VIO (1.65–3.6 V) and VCC (2.7–3.6 V) supplies. With VIO = 1.8 V and VCC = 3.3 V, input thresholds scale to 0.9 V (VIH) and 0.45 V (VIL), while outputs drive to 1.8 V levels, enabling direct connection to 1.8 V FPGAs or ASICs without external level shifters - confirmed in datasheet Section 4 and AC Characteristics Table 15-1.
