Product details
Overview
S29GL064N90TFI043 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, 25 ns page read time, and 100,000 erase cycles per sector. It implements Secured Silicon Sector with factory-programmed 128-word electronic serial number and supports boot-sector architecture with eight 4 Kword (8 KB) boot sectors for embedded firmware storage in industrial controllers.
For engineers reviewing the S29GL064N90TFI043 datasheet, S29GL064N90TFI043 pinout, S29GL064N90TFI043 application, or S29GL064N90TFI043 equivalent, key selection criteria include uniform vs. boot-sector configuration, TSOP-48 package compatibility, VIO-supported VersatileI/O™ operation (1.65–3.6 V), CFI compliance, and hardware-accelerated programming via WP#/ACC input.
Technical Context
This device uses 110 nm MirrorBit process technology to enable simultaneous hot-hole assisted erase and hot-electron injection programming across 32 Kword (64 KB) sectors. Its command-set architecture is fully JEDEC-compliant, supporting standard microprocessor write timing and internal latching of addresses/data during erase/program operations.
The S29GL064N90TFI043 integrates dual status reporting via DQ7 Data# Polling and DQ6 Toggle Bit I, plus dedicated RY/BY# output for real-time cycle completion detection. Hardware features include low-VCC write inhibition, RESET#-initiated operation termination, and WP#/ACC-driven accelerated programming with first/last sector protection independent of software sector lock settings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (4,194,304 × 16-bit words); enables full boot code + application 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-based boot loaders. |
| Page Read Time | 25 ns; reduces instruction fetch overhead when reading contiguous code blocks from 8-word buffer. |
| Erase Endurance | 100,000 cycles per sector; supports field firmware updates over 10+ years in industrial gateways. |
| Data Retention | 20 years typical; ensures long-term reliability without refresh in unpowered storage applications. |
| VIO Range | 1.65–3.6 V; allows interface voltage scaling to match 1.8 V or 3.3 V host logic without level shifters. |
| Supply Voltage | Single 3.0 V (2.7–3.6 V); eliminates need for auxiliary voltage rails in battery-powered edge devices. |
Pinout & Package
Package: 48-pin TSOP (Standard Thin Small Outline Package), lead pitch 0.5 mm, body size 12 × 20 mm - compatible with legacy PCB footprints and automated assembly processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A21 | Address Inputs | 22-bit address bus supporting full 4 Mword addressing; A-1 (DQ15) used as MSB in x16 mode. |
| DQ0–DQ15 | Data/Address Multiplexed I/O | 16-bit bidirectional data bus; DQ15 doubles as A-1 for extended addressing in x16 configuration. |
| CE# | Chip Enable | Active-low chip select; enables device for read/write when asserted, with CE#-controlled standby entry. |
| OE# | Output Enable | Active-low control for data bus drivers; decouples read data from bus contention during multi-device sharing. |
| WE# | Write Enable | Active-low strobe for command latching and write cycles; synchronizes all programming/erase command sequences. |
| WP#/ACC | Write Protect / Accelerated Program | Logic-low enables hardware sector protection; high-voltage application accelerates programming throughput in production. |
| RY/BY# | Ready/Busy Output | Open-drain active-low signal indicating active erase/program; eliminates need for polling in time-critical systems. |
| RESET# | Hardware Reset | Active-low asynchronous reset; terminates ongoing operations and restores device to known state for safe reboot. |
Key Features
| Feature | Design Value |
|---|---|
| Secured Silicon Sector | 128-word (256-byte) factory-locked region with unique 8-word electronic serial number for secure device identification and anti-cloning. |
| Boot Sector Architecture | Eight 4 Kword (8 KB) boot sectors + 127 × 32 Kword main sectors; isolates bootloader code from application updates to prevent corruption. |
| Program/Erase Suspend | Allows interruption of active program/erase to service higher-priority reads from other sectors-critical for real-time OS coexistence. |
| VersatileI/O™ Control | VIO pin sets input threshold and output drive strength; enables seamless interfacing with mixed-voltage SoCs (1.8 V/3.3 V). |
| CFI Compliance | Common Flash Interface descriptor table allows automatic detection and configuration by host BIOS/firmware without hard-coded drivers. |

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 uses 64-ball Fortified BGA (LAA064) instead of TSOP-48; no BYTE# pin support. | Targeted at high-density PCBs where BGA footprint and thermal performance outweigh manual rework constraints. | Select when board layout prioritizes signal integrity and miniaturization over serviceability and hand-soldering. |
| MX29GL640EHTI-90G | 64 Mbit, 90 ns, but lacks Secured Silicon Sector and Password Sector Protection; only supports Persistent Sector Protection. | Suitable for cost-sensitive consumer electronics where cryptographic security and factory serialization are not required. | Choose when firmware authentication is handled externally and boot-sector flexibility is secondary to BOM cost reduction. |
Compared with S29GL064S90TFI020, the S29GL064N90TFI043 offers easier prototyping and field repair via TSOP-48, while MX29GL640EHTI-90G trades security features for lower unit cost-making the original part optimal for industrial applications demanding both physical accessibility and tamper resistance.

FAQ
Is S29GL064N90TFI043 compatible with legacy S29GL064N designs using TSOP-48?
Yes, S29GL064N90TFI043 is a direct replacement for earlier S29GL064N variants in TSOP-48 package, maintaining identical pinout, timing specifications (90 ns access), and command set. The "I043" suffix denotes Infineon's post-acquisition ordering code with unchanged electrical and mechanical behavior.
Does this device support both x8 and x16 data bus configurations?
No-S29GL064N90TFI043 is x16-only. It does not support BYTE#-enabled x8 mode. The device is organized as 4,194,304 words × 16 bits; DQ15 serves as A-1 in x16 addressing, and no byte-lane selection is implemented in this variant.
What is the function of the WP#/ACC pin during normal operation versus programming?
During normal operation, asserting WP# low protects the first or last sector from accidental writes. During programming, applying 5.5 V to ACC (via WP#/ACC) accelerates internal programming voltage generation, reducing write time by ~30%-a feature intended for high-throughput manufacturing, not field use.
Can the Secured Silicon Sector be reprogrammed after factory locking?
No-the Secured Silicon Sector is permanently locked after factory programming or customer locking via command sequence. Once the 128-word region is secured, no further writes or erases are possible, including electronic serial number modification, ensuring immutable device identity.
