Product details

Overview

S29GL064N90FAI020 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 operates in uniform sector architecture with 128 × 64 KB sectors and supports boot code storage in embedded systems requiring nonvolatile program storage with hardware reset and sector-level protection.

For engineers reviewing the S29GL064N90FAI020 datasheet, S29GL064N90FAI020 pinout, S29GL064N90FAI020 application, or S29GL064N90FAI020 equivalent, key selection criteria include JEDEC-compliant command set compatibility, Secured Silicon Sector with factory-programmed 128-word ESN, flexible sector protection (Persistent/Password), and dual-mode VIO (1.65–3.6 V) for mixed-voltage system interfacing.

Technical Context

This device implements a 110 nm MirrorBit floating-gate architecture enabling simultaneous hot-hole erase and hot-electron programming across full sectors. Its command-set architecture is fully JEDEC JESD21-C compliant, supporting CFI interrogation, autoselect mode, and unlock-bypass programming to reduce multi-word write overhead.

The device integrates dedicated hardware features including RESET# for operation termination and boot recovery, RY/BY# for cycle completion signaling, WP#/ACC for accelerated programming and first/last sector write protection, and VIO-controlled I/O voltage scaling-enabling interoperability with 1.8 V or 3.3 V host logic without level shifters.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	64 Mbit (4,194,304 × 16-bit words); enables storage of ~8 MB firmware images in compact footprint.
Access Time	90 ns at VCC = 2.7–3.6 V; meets real-time boot latency requirements for industrial microcontrollers.
Erase Endurance	100,000 cycles per sector; supports field firmware updates over 10+ years in deployed equipment.
Data Retention	20 years at Tj ≤ 85 °C; ensures long-term reliability in unattended infrastructure applications.
VIO Range	1.65–3.6 V; allows direct interface to 1.8 V I/O domains while maintaining full read/write functionality.
Page Read Buffer	8-word (16-byte) buffer with 25 ns page access; accelerates sequential instruction fetch during boot.
Write Buffer	16-word (32-byte) buffer; reduces cumulative programming time for block-based firmware patches.

Pinout & Package

Package: 48-pin TSOP (Type I, standard thin small outline package), 12 × 20 mm body, lead pitch 0.5 mm. Pin-compatible with JEDEC MO-142AC standard.

Pin/Terminal	Circuit Role	Design Meaning
A0–A21	Address inputs	22-bit address bus supporting full 4M-word addressing; A-1 (DQ15) multiplexed as MSB in x16 mode.
DQ0–DQ15	Data I/O bidirectional bus	16-bit parallel interface; DQ15 functions as A-1 in x16 configuration; supports BYTE#-controlled x8/x16 mode switching.
CE#, OE#, WE#	Chip, output, and write enable controls	Independent active-low enables allow interleaved read/write operations and eliminate bus contention in multi-device systems.
WP#/ACC	Write protect / accelerated program input	Hardware lock for first/last sector; when driven high with 5.5 V, enables faster programming for production line throughput.
RY/BY#	Ready/Busy status output	Open-drain signal indicates active erase/program cycle; eliminates need for software polling in time-critical boot sequences.
RESET#	Hardware reset input	Asynchronous reset terminates all operations and restores device to known state; tied to system reset for reliable cold-boot recovery.
VIO	I/O voltage reference	Defines logic threshold for all address/data/control pins; decouples I/O voltage from core VCC for mixed-signal SoC integration.

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 and Password modes-enables permanent or password-gated lockdown of critical boot sectors against accidental/malicious overwrite.
Program/Erase Suspend	Allows host to pause ongoing programming/erasing to service higher-priority reads from other sectors-essential for real-time OS firmware updates.
CFI Compliance	JEDEC-standard Common Flash Interface enables automatic device detection and parameter retrieval by bootloader without hard-coded timing tables.
Unlock Bypass Mode	Reduces multi-word programming from 4-cycle to 2-cycle command sequence-cuts firmware update time by ~50% in large-block writes.

Applications

Use Scenario: Hosting boot loader and safety-critical display firmware in automotive digital instrument clusters with ASIL-B compliance requirements.

IC Role / Device Role / Timing Role: Secure, sector-protected Flash storing signed boot images verified before execution by MCU's ROM bootloader.

Use Value: Secured Silicon Sector with factory-programmed ESN enables cryptographic binding of firmware to specific ECUs for anti-tampering.

Medical Diagnostic Equipment BIOS

Telecom Base Station Configuration Storage

Use Scenario: Holding FDA-certified initialization routines and regulatory configuration parameters in portable ultrasound and imaging devices.

IC Role / Device Role / Timing Role: High-reliability storage element with hardware RESET# synchronization to ensure deterministic boot state after brown-out recovery.

Use Value: Persistent Sector Protection prevents unauthorized modification of calibration constants during field servicing or software updates.

Use Scenario: Storing FPGA bitstreams, radio profile tables, and network stack parameters in LTE/5G remote radio units deployed in outdoor cabinets.

IC Role / Device Role / Timing Role: Field-upgradable nonvolatile memory supporting over-the-air (OTA) firmware patching via Erase Suspend/Resume capability.

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 speed, but 56-pin TSOP package with different pinout (e.g., NC pins at positions 1–2, 55–56) and no WP#/ACC acceleration path.	Lacks hardware-accelerated programming; unsuitable for high-throughput manufacturing lines requiring ACC voltage injection.	Select when board layout uses 56-pin footprint and factory programming is performed off-line via EPROM programmer.
MX29GL640EHTI-90G	64 Mbit, 90 ns, but uses 48-ball fine-pitch BGA (VBK048); no Secured Silicon Sector or Password Protection; only Persistent Sector Protection.	Missing ESN and password-based security features; cannot meet secure boot requirements for regulated medical or automotive use.	Choose for cost-sensitive consumer applications where physical tamper resistance suffices and firmware signing is handled externally.

Compared with S29GL064N90FAI020, the S29GL064S90TFI020 trades ACC-driven throughput for TSOP pinout flexibility, while MX29GL640EHTI-90G sacrifices security features for BGA space savings-making the original part uniquely suited for secure, high-volume industrial boot memory.

FAQ

Is S29GL064N90FAI020 compatible with legacy Cypress S29GL064N designs?

Yes-Infineon maintains full pin, command-set, and timing compatibility with original Cypress S29GL064N devices. The "AI020" suffix denotes the 48-pin TSOP package with industrial temperature range (-40 °C to +85 °C) and same 90 ns access specification. No PCB or firmware changes are required for drop-in replacement.

What is the function of the WP#/ACC pin beyond write protection?

When driven to 5.5 V, the WP#/ACC pin activates accelerated programming mode, reducing individual word programming time by up to 30%. This feature is intended for high-volume system manufacturing and remains functional even when sector protection is enabled-ensuring first/last sector integrity during production flash programming.

Does the Secured Silicon Sector support customer programming?

Yes-the 128-word Secured Silicon Sector can be programmed and permanently locked either at the factory or by the end customer using the documented command sequence. Once locked, no further writes or erases are possible, and the 8-word Electronic Serial Number remains readable via standard CFI commands for device authentication.

How does Erase Suspend improve firmware update reliability in real-time systems?

Erase Suspend allows the host processor to interrupt an ongoing sector erase to read or program another sector-enabling background firmware validation or logging during long-duration erase cycles. This prevents watchdog timeouts and maintains system responsiveness, which is critical in RTOS-based industrial controllers performing concurrent diagnostics and update tasks.
