Product details

Overview

S29GL064S70TFI073 from Infineon is a 64 Mb (8 MB) parallel NOR flash memory with 3.0 V single-supply operation, 70 ns access time, uniform 32-Kword (64-KB) sector architecture, internal hardware ECC for single-bit error 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 S29GL064S70TFI073 datasheet, S29GL064S70TFI073 pinout, S29GL064S70TFI073 application, or S29GL064S70TFI073 equivalent, key selection criteria include JEDEC-compliant command set, 128-word write buffer for accelerated multi-word programming, secure silicon region with factory-programmed 8-word serial number, and TSOP-48 package compatibility with legacy board layouts.

Technical Context

This device implements MIRRORBIT™ floating-gate technology on a 65-nm process, enabling simultaneous hot-hole erase and hot-electron programming across uniform sectors. It supports byte/word configuration via BYTE# input and uses VIO (1.65 V to VCC) to define I/O voltage levels independently of core VCC.

Hardware features include dedicated RESET#, RY/BY#, and WP#/ACC pins; software features include CFI compliance, Program/Erase Suspend/Resume, and persistent/password-based sector protection. Automatic ECC operates transparently during read cycles without host intervention.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	64 Mb (4,194,304 words × 16-bit), organized as 128 uniform 32-Kword sectors
Access Time	70 ns typical - enables direct execution (XIP) from flash in real-time microcontroller boot paths
Write Buffer Size	128-word (256-byte) - reduces average programming time for firmware patching by >60% vs. single-word writes
ECC Capability	Internal hardware single-bit error correction - eliminates need for external ECC logic in safety-critical boot memory
Endurance	100,000 erase/program cycles per sector - supports field firmware update cycles over 10-year product lifetime
Data Retention	20 years typical at 85°C - meets industrial storage requirements without refresh or backup power
Supply Voltage	VCC = 2.7–3.6 V; VIO = 1.65–VCC - allows mixed-voltage system interfacing (e.g., 3.3 V core / 1.8 V I/O)
Temperature Range	–40°C to +85°C (Industrial) - qualified per AEC-Q100 Grade 3 for automotive ECUs and industrial PLCs

Pinout & Package

Package: 48-pin TSOP (Type I, 12 mm × 20 mm, 0.5 mm pitch), RoHS-compliant, lead-free, moisture sensitivity level 3.

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 bit 0 in byte mode when BYTE# = low
DQ0–DQ15	Data I/O	16-bit bidirectional data bus; functions as 8-bit bus when BYTE# = low and DQ0–DQ7 active
CE#	Chip Enable	Active-low chip select; device enters standby mode when CE# high, reducing current to 40 µA
OE#	Output Enable	Active-low output control; enables data bus drivers only during read cycles to minimize bus contention
WE#	Write Enable	Active-low write strobe; latches addresses/data for command sequences and programming operations
RESET#	Hardware Reset	Active-low asynchronous reset; terminates ongoing program/erase and restores device to read mode within 100 ns
RY/BY#	Ready/Busy Output	Open-drain status indicator; low during internal program/erase, high when ready for next command
WP#/ACC	Write Protect / Accelerated Program	Low = first/last sector hardware lock; high + 5.5 V = accelerated programming mode for production line throughput
BYTE#	Bus Width Select	Low = 8-bit data mode (DQ0–DQ7); high = 16-bit mode (DQ0–DQ15) - enables backward compatibility with 8-bit hosts
VCC, VIO, GND	Power Supplies	VCC = 3.0 V core supply; VIO sets I/O voltage level independently - decouples I/O signaling from core rail

Key Features

Feature	Design Value
Secure Silicon Region	128-word (256-byte) factory-locked area with 8-word electronic serial number - provides immutable device identity for secure boot and anti-cloning
Program/Erase Suspend	Allows host to interrupt active programming/erasing to service higher-priority reads - essential for real-time OS interrupt handling
Unlock Bypass Mode	Reduces multi-word programming overhead from 4 to 2 write cycles per word - cuts firmware update time by ~50% in host-controlled flashing
CFI Compliance	JEDEC-standard Common Flash Interface - enables automatic detection and configuration by bootloader without hard-coded timing tables
Hardware Sector Protection	WP#/ACC pin locks first/last sector independent of software protection state - prevents accidental overwrite during power-up transients

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
S29GL064S90TFI073	90 ns access time, same density/package, identical command set and ECC - slower timing but lower power in read mode	Suitable where 70 ns timing margin is not required and system clock is ≤20 MHz	Select for cost-sensitive industrial designs where boot latency < 100 ms is acceptable
MX29GL640EHTI-90G	Macronix part; 90 ns access, no built-in ECC, requires external error management; CFI-compatible but lacks Secure Silicon Region	Lacks factory-serialized secure ID and hardware ECC - unsuitable for safety-certified or anti-counterfeit use cases	Choose only for legacy replacement where security and ECC are handled at software layer

Compared with S29GL064S90TFI073 and MX29GL640EHTI-90G, the S29GL064S70TFI073 delivers the fastest deterministic access, integrated ECC, and cryptographically verifiable device identity - making it the only option meeting ASIL-B boot integrity and 20-year field retention requirements.

FAQ

Is S29GL064S70TFI073 compatible with legacy 3.3 V parallel NOR flash sockets?

Yes - it operates at 3.0 V nominal with VIO support down to 1.65 V, and its 48-pin TSOP footprint matches JEDEC MO-142AB standard. Pinout is identical to S29GL064N and other Infineon GL-N devices, enabling drop-in replacement where timing margins allow 70 ns access.

Does the Secure Silicon Region require special programming equipment?

No - the 128-word Secure Silicon Region is programmed and locked either at Infineon's factory or in-system using standard CFI commands (Enter/Exit Secure Silicon Region sequence). No high-voltage programmer is needed; locking is performed via software command with password verification.

Can S29GL064S70TFI073 operate in 8-bit data bus mode?

Yes - asserting BYTE# = low configures DQ0–DQ7 as an 8-bit data bus while disabling DQ8–DQ15. This maintains full command compatibility and sector addressing, allowing integration with 8-bit microcontrollers without glue logic or bus translators.

What happens during power loss while an erase or program operation is in progress?

The device includes a low-VCC detector that automatically suspends write operations below safe voltage thresholds. Upon power restoration, the device resumes from known-good state; status bits (DQ6 toggle, DQ7 polling) indicate incomplete operations, enabling host firmware to safely retry or abort.
