Product details

Overview

S29GL064S70TFI023 from Infineon is a 64 Mb (8 MB) parallel NOR flash memory IC with 3.0 V single-supply operation, 70 ns access time, 128-word write buffer, internal hardware ECC for single-bit correction, and industrial temperature range (–40°C to +85°C); used for boot code storage and firmware updates in embedded control systems.

For engineers reviewing the S29GL064S70TFI023 datasheet, S29GL064S70TFI023 pinout, S29GL064S70TFI023 application, or S29GL064S70TFI023 equivalent, key selection criteria include sector architecture (128 × 64-KB uniform sectors), VIO-controlled I/O compatibility (1.65 V to VCC), JEDEC CFI compliance, AEC-Q100 Grade 3 qualification, and Secure Silicon Region support.

Technical Context

This device implements a parallel interface with separate CE#, WE#, and OE# controls, supporting both 16-bit-only and byte-configurable (via BYTE#) data bus modes. Its MIRRORBIT™ 65-nm process enables hot-hole erase and hot-electron programming with full sector erase granularity.

Hardware features include RESET#-driven operation reset, RY/BY# status signaling, WP#/ACC-enabled factory or field-programmable sector protection, and automatic low-VCC write inhibition. Software features encompass CFI identification, Program/Erase Suspend/Resume, Unlock Bypass mode, and persistent/password-based sector locking.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	64 Mb (4,194,304 words × 16 bits), organized as 128 uniform 64-KB sectors
Access Time	70 ns - determines maximum sustained read throughput in legacy parallel bus systems
Write Buffer Size	128 words (256 bytes) - reduces multi-word programming overhead by batching writes
ECC Capability	Internal hardware single-bit error correction - maintains data integrity without host CPU intervention
VIO Range	1.65 V to VCC - enables flexible I/O voltage scaling independent of core supply
Endurance	100,000 erase cycles per sector - supports frequent firmware update cycles in field-deployed devices
Data Retention	20 years typical - ensures long-term reliability in unpowered storage applications

Pinout & Package

Package: 48-lead TSOP (Type I, standard pitch), compliant with JEDEC MO-142AC. Pin assignments validated per Infineon datasheet Rev. *K, pages 11–12.

Pin/Terminal	Circuit Role	Design Meaning

DQ0–DQ15	Data I/O	16-bit bidirectional data bus; BYTE# enables 8-bit mode
CE#	Chip Enable	Active-low chip select; deactivates device to reduce standby current
OE#	Output Enable	Controls output drivers during read; allows shared bus operation
WE#	Write Enable	Controls write latching and command execution timing
RESET#	Hardware Reset	Aborts ongoing operations and returns device to read mode
RY/BY#	Ready/Busy Output	Open-drain status signal indicating active program/erase completion
WP#/ACC	Write Protect / Accelerated Program	Low-level assertion protects first/last sector; high-voltage mode enables faster programming

Key Features

Feature	Design Value
Secure Silicon Region	128-word (256-byte) factory- or customer-lockable area for immutable serial number or security keys
Program/Erase Suspend	Enables concurrent read access to unprotected sectors during active program/erase - improves system responsiveness
Unlock Bypass Mode	Reduces multi-word programming command overhead from 4 to 2 write cycles - accelerates firmware patching
CFI Compliance	Standardized query table allows automatic detection and configuration by host bootloader or OS flash driver
Hardware VCC Monitor	Internally disables write commands during power ramp-up/down - prevents corruption during brown-out conditions

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
S29GL064S90TFI020	90 ns access time; same density, package, and feature set	Lower performance grade; suitable where timing margin exceeds 70 ns requirement	Select when cost sensitivity outweighs access time need and board layout accommodates identical footprint
MX29GL640EHT2I-90G	Macronix part; 90 ns access, JEDEC-compatible but lacks Secure Silicon Region and password protection	No hardware-enforced secure storage; requires external security layer for serial number management	Choose only if Secure Silicon Region is unused and CFI-based auto-detection suffices for system integration

Compared with S29GL064S90TFI020, this part delivers tighter 70 ns timing for latency-critical boot paths; versus MX29GL640EHT2I-90G, it provides integrated secure storage and stronger sector protection-critical for regulated medical and automotive deployments.

FAQ

What is the function of the WP#/ACC pin on S29GL064S70TFI023?

The WP#/ACC pin serves dual functions: when held low, it hardware-protects the first or last memory sector against accidental erase or program; when driven to accelerated voltage (V_ACC), it enables faster programming cycles. This pin operates independently of software sector protection settings and remains active even during accelerated programming sequences.

Does S29GL064S70TFI023 support byte-wide data access?

Yes - the device supports 8-bit data access when the BYTE# input is asserted low, enabling compatibility with 8-bit microcontroller buses. In this mode, DQ0–DQ7 carry data while DQ8–DQ15 are tri-stated. The 16-bit mode is active when BYTE# is high, using the full DQ0–DQ15 bus.

How does the Secure Silicon Region differ from standard sectors?

The Secure Silicon Region is a dedicated 128-word (256-byte) sector that can be permanently locked at factory or by the user via command sequence. Once locked, no further writes or erases are possible-even with elevated voltage or unlock commands-making it suitable for storing immutable electronic serial numbers or cryptographic keys.

Is S29GL064S70TFI023 compatible with legacy 5 V-only parallel flash interfaces?

No - it requires a 3.0 V ±0.3 V VCC supply and supports VIO from 1.65 V to VCC, but is not 5 V tolerant. Interface compatibility depends on host system's ability to generate 3.0 V logic levels and adhere to JEDEC-standard command sets; level-shifting circuitry is required for connection to 5 V buses.
