Product details

Overview

S29GL064N90DAI040 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.

For engineers reviewing the S29GL064N90DAI040 datasheet, S29GL064N90DAI040 pinout, S29GL064N90DAI040 application, or S29GL064N90DAI040 equivalent, key selection criteria include JEDEC-compliant command set, Secured Silicon Sector with factory-programmed 128-word ESN, CFI compliance for host auto-configuration, and hardware write protection via WP#/ACC pin.

Technical Context

This device implements a 110 nm MirrorBit floating-gate NAND architecture enabling simultaneous hot-hole erase and hot-electron programming. Its sector-based erase model isolates 64 KB blocks for independent reprogramming without disturbing adjacent sectors, while the VersatileI/O™ interface decouples VIO from VCC to support mixed-voltage system interfacing.

The command-set architecture includes full CFI compliance, Program/Erase Suspend & Resume, Unlock Bypass mode (2-cycle programming), and dual status reporting via DQ7 polling and RY/BY# output. Hardware reset (RESET#) and low-VCC write inhibition provide robust power-transition safety during boot and field updates.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	64 Mbit (4,194,304 × 16-bit words); enables full bootloader + configuration storage in single device
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 frequent firmware field updates over product lifetime
Data Retention	20 years at 125°C; validated for extended operation in automotive under-hood and industrial edge environments

Pin/Terminal	Circuit Role	Design Meaning
A0–A21	Address Inputs	22-bit address bus supporting full 4M-word addressing; A-1 used as DQ15 in x16 mode
DQ0–DQ15	Data/Address Multiplexed I/O	16-bit bidirectional data bus; DQ15 doubles as A-1 for x16 configuration
CE#, OE#, WE#	Chip/Output/Write Enable Controls	Independent gating enables precise timing control for burst reads and page programming
WP#/ACC	Write Protect / Accelerated Program Input	Hardware lock for first/last sector; high-voltage mode (VHH) reduces program time in production
RY/BY#	Ready/Busy Output	Active-low open-drain signal indicating active erase/program cycle completion
RESET#	Hardware Reset Input	Asynchronous reset clears internal state and restores read mode; ties directly to system reset rail
BYTE#	Bus Width Select	Configures x16 or x8 data interface; critical for compatibility with legacy 8-bit microcontrollers

Key Features

Feature	Design Value
Secured Silicon Sector	128-word (256-byte) factory-locked region with 8-word ESN; prevents cloning of device identity in secure boot systems
Password Sector Protection	128-bit password required to modify protected sectors; enforces firmware integrity in certified medical devices
Program/Erase Suspend	Pause active programming/erasing to service interrupts or read other sectors; essential for deterministic real-time response
CFI Compliance	Standardized query table at address 0x55 for automatic flash detection and parameter loading by BIOS/bootloader
Unlock Bypass Mode	Two-write-cycle sequence replaces four-cycle standard programming; increases throughput in high-volume manufacturing

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 timing, but 56-pin TSOP package and 110 nm process with enhanced ECC support	Targeted for telecom baseband cards requiring higher reliability under thermal cycling	Select when board layout requires 56-pin footprint or ECC-enabled error correction is mandated
MX29GL640EHT2I-90G	64 Mbit, 90 ns, but uses 48-ball fine-pitch BGA and lacks Secured Silicon Sector	Used in cost-sensitive consumer gateways where physical security is not required	Choose for space-constrained designs needing BGA footprint, accepting absence of factory-locked ESN

Compared with S29GL064S90TFI020 and MX29GL640EHT2I-90G, the S29GL064N90DAI040 uniquely delivers Secured Silicon Sector + TSOP-48 mechanical compatibility + JEDEC command set consistency - making it optimal for industrial firmware vaults where physical package interchangeability and cryptographic identity binding are jointly required.

FAQ

What is the function of the BYTE# pin on S29GL064N90DAI040?

The BYTE# pin configures the data bus width: when pulled high, the device operates in x16 mode (DQ0–DQ15 active); when pulled low, it enables x8 mode (DQ0–DQ7 only), allowing compatibility with 8-bit microcontrollers and reducing signal routing complexity on PCBs with mixed-bus architectures.

Does S29GL064N90DAI040 support hardware reset during active programming?

Yes - asserting RESET# asynchronously terminates any ongoing program or erase operation, clears internal state machines, and returns the device to read mode within 100 ns. This feature ensures safe recovery from power brownouts or watchdog timeouts without requiring external sequencers or voltage monitors.

How is the Secured Silicon Sector protected from accidental overwrite?

The Secured Silicon Sector is permanently locked via fuse-based or one-time-programmable (OTP) circuitry after factory programming. Once secured, no command sequence - including unlock bypass or sector erase - can modify its contents. Access requires a dedicated command sequence, and write attempts return status failure without altering stored data.

Can S29GL064N90DAI040 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) rails. At VIO = 1.8 V, all input thresholds and output drive levels conform to 1.8 V logic standards, enabling direct interface with low-voltage FPGAs or ASICs without level-shifting components.
