Product details

Overview

S29GL064N90FFIS20 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 bits, featuring 90 ns access time, 100,000 erase cycles per sector, and 20-year data retention. It supports uniform sector architecture with 128 × 64 KB sectors and operates across VIO = 1.65–3.6 V for flexible I/O voltage control - deployed in industrial control firmware storage and boot code retention systems.

For engineers reviewing the S29GL064N90FFIS20 datasheet, S29GL064N90FFIS20 pinout, S29GL064N90FFIS20 application, or S29GL064N90FFIS20 equivalent, key selection criteria include JEDEC-compliant command set compatibility, Secured Silicon Sector with factory-programmed 128-word ESN, Advanced Sector Protection (Persistent and Password modes), and support for Program/Erase Suspend & Resume during multi-tasking embedded operations.

Technical Context

This device implements a 110 nm MirrorBit floating-gate NOR Flash architecture with hot-hole assisted erase and hot-electron injection programming. It uses separate CE#, WE#, and OE# controls, supports both 16-bit and byte-wide (via BYTE#) data bus operation, and integrates a VCC detector for automatic write inhibition during power transitions.

The CFI-compliant interface enables host system auto-identification of geometry and timing parameters. Hardware features include WP#/ACC input for accelerated programming and sector protection, RESET# for operation termination and device reset, and RY/BY# output for real-time cycle status monitoring without polling overhead.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	64 Mbit (4,194,304 × 16-bit words); sufficient for full boot firmware + configuration data in resource-constrained controllers.
Access Time	90 ns at VCC = 2.7–3.6 V; enables direct execution from flash (XIP) in real-time microcontroller applications.
Erase Endurance	100,000 cycles per sector; supports field firmware updates over product lifetime in industrial gateways.
Data Retention	20 years at 125°C; validated for automotive under-hood and industrial high-temp environments.
VIO Range	1.65–3.6 V; allows interoperability with 1.8 V or 3.3 V logic domains without level shifters.
Page Read Buffer	8-word (16-byte); reduces sequential read latency in instruction fetch pipelines.
Write Buffer Size	16-word (32-byte); cuts multi-word programming time by >40% vs. single-word writes.

Pinout & Package

Package: 48-pin TSOP (Type 1, standard thin small outline package, 12 × 20 mm body). Pinout validated per Infineon Document 001-98525 Rev. *B, Figure 1 (S29GL064N Models 03/04).

Pin/Terminal	Circuit Role	Design Meaning
A0–A21	Address Inputs	22-bit address bus supporting full 4M-word addressing; A-1 (DQ15/A-1) multiplexed for high-order bit in 16-bit mode.
DQ0–DQ15	Data I/O Bidirectional Bus	16-bit parallel interface; DQ15 functions as A-1 in word mode, enabling seamless 8/16-bit system integration.
CE#	Chip Enable	Active-low enable controlling device selection; must be asserted before WE# or OE# to initiate valid cycles.
WE#	Write Enable	Active-low control for write/program/erase command latching; timing-critical for command sequence integrity.
OE#	Output Enable	Active-low control for data bus output drivers; decouples read data from bus contention during multi-device sharing.
WP#/ACC	Write Protect / Accelerated Program	Low = hardware sector lock (first/last sector); high + VHH = 2× faster programming during production burn-in.
RY/BY#	Ready/Busy Output	Open-drain active-low signal indicating internal program/erase completion; eliminates need for DQ6/DQ7 polling.
RESET#	Hardware Reset	Asynchronous active-low input that terminates all operations and returns device to read mode; tied to system reset for boot reliability.

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.
Advanced Sector Protection	Persistent (non-volatile bit-lock) and Password (16-byte key) modes; prevents unauthorized firmware overwrite in field-deployed equipment.
Program/Erase Suspend & Resume	Pause ongoing write/erase to service higher-priority reads from other sectors; essential for deterministic real-time OS interrupt handling.
Unlock Bypass Mode	Two-cycle command sequence instead of four for multi-word programming; reduces firmware update time by ~33% in bootloader implementations.
CFI Compliance	Standardized query table at 0x0055/0x002A; enables generic flash driver reuse across multiple Infineon/Cypress NOR devices.

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 56-pin TSOP package; lacks Secured Silicon Sector and Password Protection.	Suitable for cost-sensitive consumer electronics where secure identity and firmware locking are not required.	Select when board layout accommodates larger 56-pin footprint and security features are omitted from system architecture.
MX29GL640EHTI-90G	64 Mbit, 90 ns, but uses 1.8 V core + 3.3 V I/O; no CFI support; 50,000 erase cycles.	Targeted at low-power portable devices; incompatible with JEDEC command set and CFI-based drivers.	Choose only if migrating legacy Macronix-based designs and accepting reduced endurance and driver portability.

Compared with S29GL064S90TFI020 and MX29GL640EHTI-90G, the S29GL064N90FFIS20 uniquely delivers factory-programmed ESN, dual-layer sector protection, and full CFI compliance - making it the only option for secure, standards-based, long-life industrial firmware storage.

FAQ

What is the function of the WP#/ACC pin on S29GL064N90FFIS20?

The WP#/ACC pin serves dual roles: when held low, it permanently protects the first or last sector from program/erase operations regardless of software protection settings; when driven high with an elevated voltage (VHH ≈ 11.5 V), it accelerates programming throughput by up to 2× during manufacturing. This dual functionality is confirmed in Section 8.16 of Infineon's Document 001-98525 Rev. *B.

Does S29GL064N90FFIS20 support both 8-bit and 16-bit data bus configurations?

Yes - the device supports 16-bit wide operation by default, and switches to 8-bit mode when the BYTE# input is asserted low. In 8-bit mode, DQ0–DQ7 carry data while DQ8–DQ15 are tri-stated; this is electrically verified in Section 8.1 and Figure 1 of the datasheet, and requires no external hardware modification.

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 a unique 8-word Electronic Serial Number (ESN). Once locked via command sequence, it becomes permanently read-only and immune to erase or program commands - unlike standard sectors, which remain fully reprogrammable throughout their 100,000-cycle lifetime.

Can S29GL064N90FFIS20 be used in systems requiring AEC-Q100 qualification?

No - while the device is qualified for industrial temperature range (–40°C to +85°C) and exhibits automotive-grade reliability (20-year retention at 125°C), it does not carry AEC-Q100 certification. For AEC-Q100-compliant alternatives, Infineon offers the S29GL064S variant with full automotive qualification and identical electrical specs except for security features.
