Product details

Overview

S29GL064N90BAI040 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 boot code storage in systems requiring nonvolatile program storage with hardware reset recovery.

For engineers reviewing the S29GL064N90BAI040 datasheet, S29GL064N90BAI040 pinout, S29GL064N90BAI040 application, or S29GL064N90BAI040 equivalent, this device serves as a drop-in replacement for legacy parallel NOR Flash in industrial control firmware, automotive ECUs, and network equipment boot memory - with CFI compliance, Secured Silicon Sector, and Erase/Program Suspend capabilities critical for field-upgradable embedded systems.

Technical Context

This device uses 110 nm MirrorBit process technology to deliver high-density, single-supply NOR Flash operation with JEDEC-compliant command set and VersatileI/O™ control via VIO (1.65–3.6 V). Its architecture includes dedicated RY/BY# status output, DQ6/DQ7 polling bits, and hardware RESET# for synchronous system initialization.

It supports both uniform and boot-sector configurations, though S29GL064N90BAI040 is a uniform-sector model. Sector protection is implemented via Persistent Sector Protection and Password Sector Protection, with factory-programmable Secured Silicon Sector (128-word/256-byte) accessible only through defined command sequences.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	64 Mbit (4,194,304 × 16-bit words); enables full boot image + firmware storage in space-constrained designs
Access Time	90 ns at VCC = 2.7–3.6 V; meets real-time read latency requirements for MCU boot fetch cycles
Erase Endurance	100,000 cycles per sector; supports frequent field firmware updates without premature wear-out
Data Retention	20 years at 125°C; validated for automotive under-hood and industrial extended-temperature applications
Supply Voltage	Single 3.0 V supply (VCC = 2.7–3.6 V, VIO = 1.65–3.6 V); eliminates need for dual-rail power design
Page Read Buffer	8-word (16-byte) buffer; reduces sequential read latency by minimizing address setup overhead
Write Buffer Size	16-word (32-byte) buffer; accelerates multi-word programming by batching writes and reducing command overhead

Pinout & Package

Package: 48-pin TSOP (Standard Thin Small Outline Package), lead pitch 0.5 mm, body size 12 × 20 mm - compatible with standard surface-mount reflow profiles and legacy PCB footprints.

Pin/Terminal	Circuit Role	Design Meaning
A0–A21	Address Inputs	22-bit address bus supporting full 4M-word addressing; A-1 (DQ15/A-1) multiplexes most significant data bit and address bit
DQ0–DQ15	Data I/O Bus	16-bit bidirectional data path; supports byte-wide operation when BYTE# = low (not used in this uniform-sector TSOP variant)
CE#	Chip Enable	Active-low chip select; must be asserted before WE# or OE# to enable device operation
OE#	Output Enable	Active-low control for data output driver; decouples read timing from CE# deassertion
WE#	Write Enable	Active-low control for write/program/erase command latching; synchronized with address/data setup
RY/BY#	Ready/Busy Output	Open-drain status signal indicating active programming/erase; allows host to poll asynchronously without data bus contention
RESET#	Hardware Reset	Active-low asynchronous reset; terminates ongoing operations and returns device to read mode - tied to system reset for boot reliability
WP#/ACC	Write Protect / Accelerated Program	Input with dual function: logic low enables hardware sector protection; high-voltage pulse (VHH) enables accelerated programming for production throughput

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
Erase/Program Suspend	Allows interruption of erase or program in one sector to read/program another - essential for real-time OS interrupt handling during firmware update
CFI Compliance	Enables automatic detection and configuration by host BIOS/bootloader without hard-coded timing or geometry tables
VersatileI/O™ Control	VIO pin sets all I/O voltage thresholds (1.65–3.6 V); permits direct interfacing with 1.8 V, 2.5 V, or 3.3 V microcontrollers without level shifters
Advanced Sector Protection	Persistent and password-based protection modes prevent unauthorized firmware modification - required for ISO 26262 ASIL-B compliant systems

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
S29GL064S90TFI010	Same density and speed, but 56-pin TSOP package with different pinout (e.g., NC pins at 1–2, 55–56); no WP#/ACC dual function - separate ACC pin	Requires PCB redesign due to pin count and layout mismatch; lacks integrated write protect on WP#/ACC	Select only if board layout accommodates 56-pin footprint and system uses discrete acceleration control
MX29GL640EHTI-90G	64 Mbit, 90 ns, but uses 1.8 V core (VCC = 1.7–2.0 V) with 3.3 V I/O; no Secured Silicon Sector or CFI support	Not suitable for direct replacement: incompatible voltage domain, missing security features, and non-JEDEC command set	Consider only for new designs prioritizing ultra-low power over legacy compatibility and security

Compared with S29GL064S90TFI010, the S29GL064N90BAI040 offers pin-compatible TSOP-48 footprint and integrated WP#/ACC functionality; versus MX29GL640EHTI-90G, it delivers superior security, CFI interoperability, and single 3.0 V operation - making it the preferred choice for industrial and automotive firmware storage where reliability and standards compliance are mandatory.

Manufacturer

Infineon Technologies acquired Cypress Semiconductor in 2020 and now owns and supports the MirrorBit Flash portfolio, delivering high-reliability nonvolatile memory for automotive, industrial, and communications markets.

The S29GL-N family was designed specifically for mission-critical embedded boot and firmware storage, emphasizing data integrity, long-term retention, and hardware-enforced security - not general-purpose data logging or high-speed streaming.

FAQ

Is S29GL064N90BAI040 compatible with legacy S29GL064N devices from Cypress?

Yes - Infineon maintains full pin, command-set, and timing compatibility with all prior Cypress S29GL064N variants. The part number suffix "AI040" denotes the 48-pin TSOP package with industrial temperature range (–40°C to +85°C) and same 90 ns access specification. No firmware or hardware changes are required for migration.

What is the function of the WP#/ACC pin during normal operation?

When held low, WP#/ACC enables hardware write protection for the first or last sector regardless of software protection settings. When driven to VHH (typically 11–12 V), it activates accelerated programming mode, reducing single-word program time by ~30% - intended for high-volume manufacturing, not field use.

Does this device support byte-wide data access?

No - S29GL064N90BAI040 is a 16-bit-only configuration. The BYTE# pin is present but not functional in this TSOP-48 variant; it is reserved for boot-sector models with 8/16-bit selectable operation. Data must be written and read as 16-bit words aligned to even addresses.

How is the Secured Silicon Sector accessed and protected?

Access requires issuing the Enter Secured Silicon Sector command sequence (0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00) followed by standard read commands. Once locked via the Lock Secured Silicon Sector command, no further writes or erases are possible - even with VPP applied - ensuring permanent device identity and calibration data integrity.
