Product details
Overview
S29GL064S90TFA043 from Infineon is a 64 Mb (8 MB) parallel NOR flash memory with 3.0 V single-supply operation, 70 ns access time, 128-word write buffer, internal hardware ECC for single-bit error correction, and secure silicon region with factory-programmed 128-word electronic serial number. It serves as boot code storage in industrial control systems requiring AEC-Q100 Grade 2 qualification (–40°C to +105°C).
For engineers reviewing the S29GL064S90TFA043 datasheet, S29GL064S90TFA043 pinout, S29GL064S90TFA043 application, or S29GL064S90TFA043 equivalent, this device supports JEDEC-compliant command sets, sector-level erase suspend/resume, unlock bypass programming, and flexible 16-bit/8-bit data bus configuration via BYTE# input.
Technical Context
The S29GL064S90TFA043 implements MIRRORBIT™ floating-gate technology on a 65-nm process, enabling simultaneous hot-hole erase and hot-electron programming across uniform 32-Kword sectors. Its architecture includes dedicated RY/BY# status output, DQ6/DQ7 polling support, and CFI-compliant identification for host auto-configuration.
Hardware protection integrates low-VCC detection, WP#/ACC-controlled first/last sector lock, and RESET#-driven operation termination. The secure silicon region is permanently locked post-configuration, and ECC operates transparently during read cycles without software intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mb (4,194,304 words × 16 bits), organized as 127 × 32-Kword main sectors + 8 × 4-Kword boot sectors |
| Access Time | 70 ns at VCC = 3.0 V ± 0.3 V; defines maximum clock-to-data delay in high-speed read operations |
| Erase Endurance | 100,000 cycles per sector; enables field firmware updates over extended product lifetime |
| Data Retention | 20 years typical at 85°C; ensures long-term reliability in industrial and automotive environments |
| Write Buffer Size | 128-word (256-byte); reduces multi-word programming time by batching writes into single command execution |
| ECC Capability | Internal hardware single-bit error correction; eliminates need for external ECC logic in safety-critical boot storage |
| Operating Voltage | VCC = 2.7–3.6 V, VIO = 1.65–VCC; decouples I/O voltage from core supply for mixed-voltage system interfacing |
Pinout & Package
This device is packaged in a 48-ball fine-pitch BGA (VBK048, 8.15 mm × 6.15 mm × 1.0 mm) with 16-bit parallel interface and dedicated control pins for CE#, OE#, WE#, RESET#, RY/BY#, WP#/ACC, and BYTE#.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A22 | Address Inputs | 23-bit address bus supporting full 4-Mword addressing; A0 selects LSB in word mode or byte within word in byte mode |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus; BYTE# input configures DQ0–DQ7 as 8-bit bus when asserted low |
| CE# | Chip Enable | Active-low chip select; device enters standby mode when deasserted, reducing current to 40 µA |
| OE# | Output Enable | Active-low read strobe; controls output drivers independently of CE# for multiplexed bus sharing |
| WE# | Write Enable | Active-low signal initiating command latching or data programming; must be synchronized with address and data setup/hold |
| RESET# | Hardware Reset | Active-low asynchronous reset; terminates ongoing program/erase and returns device to read mode |
| RY/BY# | Ready/Busy Output | Open-drain status indicator; low during active program/erase, high when operation complete or in read mode |
| WP#/ACC | Write Protect / Accelerated Program | Input with dual function: protects first/last sector when low; enables accelerated programming when high-voltage applied |
| BYTE# | Bus Width Select | Configures data bus width: high = 16-bit word mode, low = 8-bit byte mode using DQ0–DQ7 only |
Key Features
| Feature | Design Value |
|---|---|
| Secure Silicon Region | 128-word (256-byte) factory-programmed serial number area with permanent lock capability for secure boot authentication |
| Erase Suspend/Resume | Allows host to pause background sector erase to service real-time read/program requests in other sectors |
| Unlock Bypass Programming | Reduces multi-word programming overhead from four to two write cycles per word, accelerating firmware patching |
| Advanced Sector Protection | Combines persistent lock bits and password-based sector locking to prevent unauthorized firmware modification |
| CFI Compliance | Enables automatic device identification and parameter retrieval by host BIOS/bootloader without hard-coded timing assumptions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL064S90TFI043 | Same die, industrial temperature grade (–40°C to +85°C), identical pinout and command set | Lacks AEC-Q100 qualification; not suitable for automotive safety-critical boot paths | Select when cost-sensitive industrial designs do not require automotive qualification or extended temperature range |
| S29GL064S10TFI043 | Slower 100 ns access time, same density and package, identical feature set except timing | Higher latency limits use in real-time boot sequences where <80 ns response is mandated | Choose for non-time-critical firmware storage where lower power consumption at reduced speed is prioritized |
Compared with S29GL064S90TFA043, the S29GL064S90TFI043 offers identical functionality at lower cost but excludes automotive qualification, while the S29GL064S10TFI043 trades 30 ns of access speed for broader voltage tolerance and marginally lower active current - both require no PCB redesign but differ in thermal and timing validation scope.

FAQ
What is the function of the BYTE# pin on S29GL064S90TFA043?
The BYTE# pin configures the data bus width: when high, the device operates in 16-bit word mode using DQ0–DQ15; when low, it switches to 8-bit byte mode using only DQ0–DQ7. This allows compatibility with both 16-bit and 8-bit host processors without external bus transceivers or glue logic.
How does the Secure Silicon Region work and how is it programmed?
The Secure Silicon Region is a dedicated 128-word (256-byte) sector containing a factory-programmed electronic serial number. It can be permanently locked via command sequence after customer programming; once locked, no further writes or erases are possible. Locking is irreversible and enforced by on-die fuse-like circuitry.
Does S29GL064S90TFA043 support both uniform and boot sector architectures?
Yes - this specific part number implements the boot sector architecture: 127 uniform 32-Kword sectors plus eight 4-Kword boot sectors. The boot sectors are located at the top or bottom of the address space and support independent protection, enabling safe in-field firmware updates without risking bootloader corruption.
What is the role of the WP#/ACC pin during accelerated programming?
When a 5.5 V voltage is applied to WP#/ACC, the device enters accelerated programming mode, reducing individual word programming time by ~30%. This mode is intended for factory programming only; during normal operation, asserting WP#/ACC low protects the first or last sector regardless of software protection settings.
