Product details
Overview
S29GL064N90TFA04 from Cypress Semiconductor is a 64 Mbit (8 MB), 3.0 V single-power-supply MirrorBit Flash memory organized as 4,194,304 words × 16 bits, featuring 90 ns access time, 25 ns page read time, and uniform 64 KB sector architecture with 128 sectors. It supports 16-bit data bus operation, CFI compliance, and hardware reset (RESET#) for boot firmware storage in embedded systems.
For engineers reviewing the S29GL064N90TFA04 datasheet, S29GL064N90TFA04 pinout, S29GL064N90TFA04 application, or S29GL064N90TFA04 equivalent, key selection criteria include sector protection mode (Persistent/Password), VIO voltage range (1.65–3.6 V), Secured Silicon Sector availability, and TSOP-48 package compatibility with industrial control and networking boot memory designs.
Technical Context
This device implements Cypress's 110 nm MirrorBit floating-gate technology with hot-hole assisted erase and hot-electron injection programming. It uses JEDEC-standard command sets and supports both uniform and boot-sector configurations - though S29GL064N90TFA04 is a uniform-sector model with 128 × 64 KB sectors.
Hardware features include dedicated WP#/ACC input for accelerated programming and first/last sector write protection, RY/BY# output for cycle status monitoring, and VIO-referenced I/O enabling flexible interface voltage scaling. The Secured Silicon Sector provides factory- or customer-lockable 256-byte region with 8-word ESN for secure identification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (4,194,304 × 16-bit words); enables full boot code + firmware image storage in space-constrained embedded hosts. |
| Access Time | 90 ns at VCC = 2.7–3.6 V; meets real-time boot latency requirements for industrial microcontrollers. |
| Page Read Time | 25 ns; reduces sequential instruction fetch overhead during CPU initialization sequences. |
| Erase Endurance | 100,000 cycles per sector; supports field firmware updates over 10+ years in deployed gateways. |
| Data Retention | 20 years at 125°C; ensures long-term reliability in automotive under-hood and telecom base station environments. |
| VIO Range | 1.65–3.6 V; allows direct interfacing with 1.8 V or 3.3 V logic without level shifters. |
| Supply Voltage | Single 3.0 V supply (2.7–3.6 V); eliminates need for auxiliary voltage rails in low-power edge devices. |
Pinout & Package
Package: 48-pin TSOP (Standard Thin Small Outline Package), 12 × 20 mm body, JEDEC MO-142AC compliant. Pin-compatible with legacy parallel NOR Flash sockets in industrial PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A21 | Address Inputs | 22-bit address bus supporting full 4 MB word addressing; A-1 (DQ15) used for x16/x8 configuration detection. |
| DQ0–DQ15 | Data/Address Bus | 16-bit bidirectional data bus; DQ15 functions as A-1 during autoselect to indicate x16 mode. |
| CE#, OE#, WE# | Chip/Output/Write Enable | Independent active-low controls enable precise timing isolation between read, write, and chip-select operations. |
| WP#/ACC | Write Protect / Accelerated Program | Asserting high voltage (VHH) on this pin cuts programming time; logic-low protects first/last sector regardless of software protection state. |
| RESET# | Hardware Reset Input | Asynchronous active-low signal that terminates ongoing erase/program and restores device to read mode - critical for safe boot recovery. |
| RY/BY# | Ready/Busy Output | Open-drain status indicator; pulled low during internal operations, enabling interrupt-driven host polling without constant register reads. |
| BYTE# | Bus Width Select | Configures 16-bit (high) or 8-bit (low) data interface; supports legacy 8-bit microcontroller integration. |
| VIO | I/O Supply Reference | Separate voltage reference for all input thresholds and output drive levels - decouples I/O logic from core VCC for mixed-voltage systems. |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory- or customer-programmable region with permanent lock; stores cryptographic keys or unique device IDs immune to field reprogramming. |
| Advanced Sector Protection | Persistent Sector Protection (PPB) and Password Sector Protection (PSP) provide dual-layer write/erase disable - prevents unauthorized firmware modification in certified medical or industrial devices. |
| Program/Erase Suspend | Allows host to pause active program/erase in one sector and read/program another - enables concurrent firmware update and runtime diagnostics without system stall. |
| CFI Compliance | Common Flash Interface support enables automatic device detection and parameter retrieval by bootloader, eliminating hard-coded timing constants across multiple Flash vendors. |
| Unlock Bypass Mode | Reduces multi-word programming overhead from 4 to 2 write cycles per word - improves production line throughput during system-level flash programming. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel NOR Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL064S90TFI02 | Same density and speed, but uses 56-pin TSOP package and includes boot-sector architecture (127 × 64 KB + 8 × 8 KB). | Designed for x86-compatible BIOS storage where boot-sector prioritization is required; lacks Secured Silicon Sector. | Select when legacy PC-style boot partitioning is mandatory and secure ID storage is not needed. |
| MX29GL640EHT2I-90G | Micron 64 Mbit parallel NOR with 90 ns access, but only supports 1.8 V I/O (no VIO pin) and lacks Password Sector Protection. | Lower-cost alternative for consumer electronics where advanced security features are omitted per design spec. | Choose for cost-sensitive applications with fixed 1.8 V logic interface and no requirement for field-updatable secure regions. |

FAQ
Is S29GL064N90TFA04 compatible with standard JEDEC parallel NOR Flash command sets?
Yes. It fully complies with the JEDEC JESD21-C standard for single-power-supply Flash, supporting identical command sequences for read, program, sector erase, chip erase, and autoselect. Host systems using legacy AMD or Spansion-compatible firmware require zero modifications to interface with this device.
What is the function of the VIO pin, and can it be tied to VCC?
VIO sets input threshold voltages and output drive levels independently of VCC. It must be connected to the host processor's I/O voltage rail (1.65–3.6 V), not necessarily VCC. Tying VIO to VCC is permissible only if the host operates at the same voltage; mismatched VIO/VCC causes timing violations or bus contention.
Does S29GL064N90TFA04 support 8-bit data bus operation?
Yes, via the BYTE# pin. When BYTE# is low, the device operates in x8 mode using DQ0–DQ7 only; A-1 (DQ15) becomes unused. This enables drop-in replacement in legacy 8-bit microcontroller designs without PCB redesign, preserving pin count and routing.
How is the Secured Silicon Sector protected, and can it be reprogrammed after locking?
The Secured Silicon Sector is locked permanently via a one-time fuse or persistent PPB bit. Once secured, no command - including chip erase - can modify its contents. Factory programming occurs pre-shipment; customer locking requires issuing the Lock Command Sequence, after which the sector becomes read-only for life.
