Product details
Overview
S29GL064N90TAI043 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 both standard and accelerated programming via WP#/ACC input for factory throughput.
For engineers reviewing the S29GL064N90TAI043 datasheet, S29GL064N90TAI043 pinout, S29GL064N90TAI043 application, or S29GL064N90TAI043 equivalent, key selection criteria include JEDEC software compatibility, Secured Silicon Sector with factory-programmed 128-word ESN, CFI compliance for host auto-configuration, and hardware reset (RESET#) support for boot firmware recovery in embedded systems.
Technical Context
This device uses 110 nm MirrorBit process technology to enable simultaneous hot-hole assisted erase and hot-electron injection programming. Its VersatileI/O™ control ties all input/output voltage thresholds to VIO (1.65–3.6 V), decoupling I/O logic levels from core VCC (2.7–3.6 V) for mixed-voltage system integration.
The command-set architecture supports full JEDEC-compliant operations including Autoselect, Chip/Sector Erase, Program Suspend/Resume, and Erase Suspend/Resume. Status reporting is implemented via DQ7 Data# Polling, DQ6/DQ2 toggle bits, and dedicated RY/BY# output - enabling concurrent background operations without host polling overhead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (4,194,304 × 16-bit words); enables storage of large boot images or firmware binaries in space-constrained designs. |
| Access Time | 90 ns at VCC = 2.7–3.6 V, VIO = 2.7–3.6 V; meets real-time read latency requirements for microcontroller boot code execution. |
| Erase Endurance | 100,000 cycles per sector; supports field firmware updates over extended product lifetime in industrial controllers. |
| Data Retention | 20 years typical at 125 °C; ensures long-term reliability in automotive under-hood or industrial high-temperature environments. |
| Page Read Buffer | 8-word (16-byte) buffer with 25 ns page read time; accelerates sequential instruction fetch during boot or runtime code loading. |
| Write Buffer | 16-word (32-byte) buffer; reduces multi-word programming time by batching writes and minimizing command overhead. |
| Secured Silicon Sector | 128-word (256-byte) factory-lockable region with 8-word ESN; provides immutable device identity for secure boot authentication or licensing. |
Pinout & Package
Package: 48-pin TSOP (Standard Thin Small Outline Package), compliant with JEDEC MO-142AA. Pin count and layout match industry-standard flash socket footprints for drop-in replacement in legacy designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A21 | Address Inputs | 22-bit address bus supporting full 64 Mbit addressing; A-1 (DQ15/A-1) serves dual role as MSB address or data bit in byte mode. |
| DQ0–DQ15 | Data/Address Bus | 16-bit bidirectional data bus; DQ15 doubles as A-1 for extended addressing in word mode configurations. |
| CE#, OE#, WE# | Chip/Output/Write Enable | Independent control lines allow interleaved read/write operations and eliminate bus contention in multi-device systems. |
| WP#/ACC | Write Protect / Accelerated Program | Logic-low assertion protects first/last sector; high-voltage application enables faster programming during manufacturing test or field update. |
| RESET# | Hardware Reset Input | Asynchronous active-low signal terminates ongoing erase/program and restores device to known state - critical for safe boot recovery. |
| RY/BY# | Ready/Busy Output | Open-drain status indicator synchronized to internal operation completion; eliminates need for continuous DQ7/DQ6 polling in timing-critical systems. |
| VIO | I/O Supply Voltage | Separate 1.65–3.6 V supply sets logic thresholds for all pins - enables direct interface to 1.8 V, 2.5 V, or 3.3 V host processors without level shifters. |
Key Features
| Feature | Design Value |
|---|---|
| CFI Compliance | Enables automatic detection and configuration by host BIOS/firmware without hard-coded timing or geometry parameters. |
| Program/Erase Suspend | Allows interrupting active program/erase to service higher-priority reads - essential for real-time OS environments with concurrent flash access. |
| Advanced Sector Protection | Combines Persistent (non-volatile lock-bit) and Password-based protection to prevent unauthorized firmware modification in deployed devices. |
| Unlock Bypass Mode | Reduces multi-word programming from four to two write cycles per data word - cuts production programming time by ~50% in high-volume manufacturing. |
| Hardware Data Protection | Low-VCC detector disables writes during power ramp-up/down; prevents corruption during brown-out or cold-start conditions. |
Applications
| Industrial PLC Firmware Storage | Automotive Instrument Cluster Boot Memory |
|---|---|
|

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 and no Secured Silicon Sector; lacks factory-programmed ESN. | Suitable for cost-sensitive consumer electronics where device identity and secure boot are not required. | Select when footprint compatibility with 56-pin sockets is needed and security features are unnecessary. |
| MX29GL640EHT2I-90G | 64 Mbit, 90 ns, but uses 48-ball fine-pitch BGA; requires different PCB layout and has no WP#/ACC acceleration path. | Better suited for space-constrained portable designs; lacks hardware reset and suspend/resume command support. | Choose only if BGA packaging is mandatory and real-time suspend functionality is not used in the system architecture. |
Compared with S29GL064S90TFI020 and MX29GL640EHT2I-90G, the S29GL064N90TAI043 uniquely combines TSOP-48 compatibility, hardware-accelerated programming, and factory-secured silicon - making it optimal for industrial and automotive applications demanding both physical design continuity and firmware security.

FAQ
What is the function of the WP#/ACC pin on S29GL064N90TAI043?
The WP#/ACC pin serves dual functions: as WP# (Write Protect), it locks the first or last sector when asserted low, preventing accidental writes even during accelerated programming; as ACC (Accelerated Program), applying 5.5 V ±0.3 V enables faster internal programming voltages, reducing write times by up to 40% in production test environments.
Does S29GL064N90TAI043 support byte-wide data access?
Yes - when BYTE# is driven low, the device operates in 8-bit mode using DQ0–DQ7 only, with A0–A20 addressing bytes instead of words. This allows compatibility with 8-bit microcontrollers and simplifies PCB routing in cost-sensitive designs without sacrificing memory capacity.
How does the Secured Silicon Sector differ from standard flash sectors?
The Secured Silicon Sector is a dedicated 128-word (256-byte) region that can be permanently locked at factory or by customer. Once protected, no erase or program commands affect its contents. It contains an 8-word electronic serial number and supports secure boot key storage, unlike standard sectors which remain fully reprogrammable.
Can S29GL064N90TAI043 be used in systems with 1.8 V I/O interfaces?
Yes - the VIO pin accepts 1.65–3.6 V, so setting VIO = 1.8 V configures all input thresholds and output drive levels for 1.8 V logic compatibility. Core VCC remains at 3.0 V (2.7–3.6 V range), maintaining full performance while enabling direct connection to 1.8 V FPGAs or SoCs without level-shifting circuitry.
