Product details

Overview

S29GL064S70TFI040 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, and integrated hardware ECC for single-bit error correction. It features uniform 64-KB sectors, secure silicon region with factory-programmed 16-byte serial number, and operates across –40°C to +85°C industrial temperature range in 48-lead TSOP package.

For engineers reviewing the S29GL064S70TFI040 datasheet, S29GL064S70TFI040 pinout, S29GL064S70TFI040 application, or S29GL064S70TFI040 equivalent, this device supports boot code storage, firmware updates, and secure configuration data retention in embedded control systems requiring JEDEC-compliant parallel flash with persistent sector protection and erase suspend/resume capability.

Technical Context

The S29GL064S70TFI040 implements a 16-bit parallel interface with BYTE# input enabling optional 8-bit mode, and uses Infineon's 65-nm MIRRORBIT™ process for high reliability. It supports command-set compatibility with JEDEC JESD21-C and includes CFI compliance for automatic device identification.

Its architecture integrates hardware reset (RESET#), ready/busy output (RY/BY#), and WP#/ACC pin for accelerated programming and first/last sector write protection. Internal ECC operates transparently during read cycles without software intervention, correcting single-bit errors in real time.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	64 Mb (8 MB), organized as 4,194,304 × 16-bit words - enables full boot image and application firmware storage in single device.
Access Time	70 ns - ensures deterministic timing for real-time microcontroller boot and code execution from flash.
Write Buffer Size	128-word (256-byte) - reduces multi-word programming overhead by batching writes, improving firmware update efficiency.
ECC Support	Internal hardware single-bit error correction - eliminates need for external error-handling logic in safety-critical applications.
Operating Voltage	VCC = 2.7–3.6 V, VIO = 1.65–VCC - allows flexible I/O voltage scaling independent of core supply for mixed-voltage system interfacing.
Endurance	100,000 erase/program cycles per sector - supports field-upgradable firmware with long service life in industrial controllers.
Data Retention	20 years typical - guarantees reliable storage of calibration data, security keys, and configuration parameters over product lifetime.

Pinout & Package

Package: 48-lead TSOP (Thin Small Outline Package), 12 mm × 20 mm × 1.2 mm body, standard JEDEC MO-142AC footprint.

Pin/Terminal	Circuit Role	Design Meaning
A0–A21	Address Inputs	22-bit address bus supporting full 4-Mword addressing; A0 selects LSB in 16-bit mode or byte lane in 8-bit mode via BYTE#.
DQ0–DQ15	Data I/O	16-bit bidirectional data bus; direction controlled by WE# and OE#; supports byte-wide access when BYTE# = low.
CE#	Chip Enable	Active-low chip select; device enters standby mode when CE# high, reducing current to 40 µA.
OE#	Output Enable	Active-low control for data bus drivers; enables read data output without affecting internal state.
WE#	Write Enable	Active-low signal initiating command latching, program, or erase; must meet tWP timing for valid command execution.
RESET#	Hardware Reset	Active-low asynchronous reset; terminates ongoing program/erase and returns device to read mode for safe boot recovery.
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	Low = hardware sector protection (first/last sector); high + VHH = accelerated programming for production throughput.
BYTE#	Bus Width Select	Low = 8-bit data mode (DQ0–DQ7 active); high = 16-bit mode (DQ0–DQ15 active) - enables pin-compatible migration.
VCC, VIO, GND	Power & Ground	VCC = 3.0 V core supply; VIO sets I/O voltage level (1.65–3.6 V); separate pins decouple noise-sensitive analog circuitry.

Key Features

Feature	Design Value
Secure Silicon Region	128-word (256-byte) factory-locked area with 16-byte electronic serial number - provides immutable device identity for secure boot and anti-cloning.
Erase Suspend/Resume	Pause background sector erase to read/program other sectors - enables concurrent firmware update and runtime code execution.
Unlock Bypass Programming	Two-cycle command sequence instead of four - cuts multi-word programming time by ~50% in host-controlled updates.
Persistent Sector Protection	Non-volatile lock bits disable program/erase in selected sectors without high-voltage requirement - replaces legacy 12 V protection schemes.
CFI Compliance	Standardized query table at 0x0055 address - allows automatic detection and parameter negotiation by bootloader or flash utility software.

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
S29GL064S90TFI040	90 ns access time, same density/package, identical command set - slower timing but lower power in read mode (18 mA @ 5 MHz).	Preferred where boot latency < 100 ns is acceptable and thermal budget limits active current.	Select for cost-sensitive industrial gateways with relaxed timing margins.
MX29GL640EHTI-90G	Macronix 64 Mb parallel NOR, 90 ns, no integrated ECC, requires external error handling; CFI compliant but lacks Secure Silicon Region.	Suitable for non-safety-critical consumer electronics where firmware integrity is managed at software layer.	Choose when BOM cost reduction outweighs need for hardware ECC and secure identity.

Compared with S29GL064S90TFI040 and MX29GL640EHTI-90G, the S29GL064S70TFI040 delivers tighter 70 ns timing for deterministic boot, built-in ECC for radiation-tolerant operation, and factory-programmed secure silicon - making it optimal for industrial control, automotive, and medical systems requiring guaranteed data integrity and traceability.

FAQ

Does S29GL064S70TFI040 support 8-bit data bus operation?

Yes, it supports 8-bit mode via the BYTE# input pin. When BYTE# is driven low, only DQ0–DQ7 are active as an 8-bit data bus while DQ8–DQ15 are tri-stated. This enables backward compatibility with legacy 8-bit microcontrollers without requiring PCB redesign.

What is the function of the WP#/ACC pin in normal operation?

In normal operation, WP#/ACC serves dual roles: when held low, it hardware-protects the first or last 64-KB sector from accidental erase or program; when driven high with elevated voltage (VHH ≈ 9 V), it enables accelerated programming for faster production-line flashing.

How does the Secure Silicon Region differ from standard flash sectors?

The Secure Silicon Region is a dedicated 128-word (256-byte) sector that can be permanently locked at factory or by customer using a command sequence. Once locked, no further writes or erases are possible - unlike standard sectors, it cannot be unlocked or reconfigured, ensuring immutable device identity or security keys.

Is the internal ECC applied automatically during all read operations?

Yes, hardware ECC is fully transparent and enabled by default on every read access. Single-bit errors within a 16-bit word are corrected in real time without CPU intervention or additional latency; uncorrectable multi-bit errors trigger DQ7/DQ6 toggle behavior to alert host software.
