Product details

Overview

S29GL064S70TFA040 from Infineon is a 64 Mb (8 MB) parallel NOR flash memory IC using 65-nm MIRRORBIT™ technology, operating from a single 3.0 V supply with 70 ns access time, 128-word write buffer, and integrated hardware ECC for single-bit error correction. It features uniform 64-KB sectors, industrial temperature range (–40°C to +85°C), and 48-lead TSOP package - deployed in boot firmware storage for industrial controllers.

For engineers reviewing the S29GL064S70TFA040 datasheet, S29GL064S70TFA040 pinout, S29GL064S70TFA040 application, or S29GL064S70TFA040 equivalent, key selection criteria include JEDEC-compliant command set, sector-level erase flexibility, Secure Silicon Region programmability, VIO-controlled I/O voltage range (1.65 V to VCC), and AEC-Q100 Grade 3 qualification status.

Technical Context

This device implements a parallel asynchronous interface with separate CE#, WE#, and OE# controls, supporting both 16-bit word and 8-bit byte configurations via BYTE# input. Its architecture enables simultaneous read/program or read/erase operations through Program Suspend and Erase Suspend features.

Internal hardware ECC operates transparently during read cycles, correcting single-bit errors without host intervention. The Secure Silicon Region provides a factory- or customer-lockable 128-word (256-byte) area with permanent protection enforced by command-sequence-based locking and PPB bit control.

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 - defines maximum address-to-valid-data delay under specified VCC and load conditions
Write Buffer Size	128 words (256 bytes) - reduces multi-word programming overhead by batching writes
ECC Support	On-die hardware single-bit error correction - ensures data integrity without software overhead
VIO Range	1.65 V to VCC - allows I/O voltage independence from core supply for mixed-voltage system interfacing
Endurance	100,000 erase cycles per sector - guarantees long-term field reliability in firmware update scenarios
Data Retention	20 years typical - supports extended product lifecycle without refresh requirements

Pinout & Package

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

Pin/Terminal	Circuit Role	Design Meaning
A0–A21	Address Inputs	22-bit address bus supporting full 4-Mword addressing; latched internally during command execution
DQ0–DQ15	Data I/O	16-bit bidirectional data bus; BYTE# selects 8-bit mode for legacy controller compatibility
CE#	Chip Enable	Active-low enable controlling device selection; required assertion for all read/write/erase operations
OE#	Output Enable	Active-low control enabling output drivers during read cycles only
WE#	Write Enable	Active-low strobe latching address/data/command on rising edge for write/erase sequences
RESET#	Hardware Reset	Active-low asynchronous reset terminating ongoing operations and returning device to read mode
RY/BY#	Ready/Busy Output	Open-drain status indicator signaling active program/erase cycle completion
WP#/ACC	Write Protect / Accelerated Program	Low = protects first/last sector; high-voltage pulse enables accelerated programming for production throughput

Key Features

Feature	Design Value
Secure Silicon Region	128-word (256-byte) factory- or user-lockable sector with irreversible protection via command sequence and PPB bit
Program/Erase Suspend	Enables real-time interruption of programming or erasing to service higher-priority reads from other sectors
Unlock Bypass Mode	Reduces multi-word programming command overhead from 4 to 2 write cycles per data word
Advanced Sector Protection	Combines persistent lock bits and password-based sector protection for hierarchical firmware security
CFI Compliance	JEDEC-standard Common Flash Interface enables automatic device identification and parameter discovery at system boot

IC Role / Device Role / Timing Role: Primary nonvolatile storage for power-on self-test (POST) routines and hardware initialization sequences.

Use Value: 20-year data retention and CFI compliance simplify regulatory documentation; sector erase architecture isolates updates from critical boot code.

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, industrial temperature (–40°C to +85°C), same 48-pin TSOP package	Lacks AEC-Q100 qualification; lower performance margin for timing-critical boot paths	Select when cost sensitivity outweighs 20 ns access time requirement and automotive qualification is unnecessary
S29GL064S70TFI020	Identical 70 ns speed and 48-pin TSOP, but rated only for industrial (not automotive) temperature range	No AEC-Q100 Grade 3 certification; unsuitable for under-hood or dashboard-mounted systems	Choose for industrial HMI or gateway applications where extended temperature is not required

Compared with S29GL064S70TFA040, the alternatives trade off automotive qualification (AEC-Q100 Grade 3) and/or access speed to reduce cost - making them viable only where environmental stress or boot latency constraints are relaxed.

FAQ

What is the function of the WP#/ACC pin on S29GL064S70TFA040?

The WP#/ACC pin serves dual functions: when held low, it hardware-protects the first or last memory sector against accidental program/erase; when pulsed with elevated voltage (V_ACC), it enables accelerated programming for faster production-line flashing. This pin remains active even during Secure Silicon Region locking and does not affect internal ECC operation.

Does S29GL064S70TFA040 support byte-wide data access?

Yes - the device supports 8-bit data access when the BYTE# input is asserted low, configuring DQ0–DQ7 as the active data bus while disabling DQ8–DQ15. This mode maintains full command-set compatibility and preserves sector protection settings, enabling integration with legacy 8-bit microcontrollers without external data-width translation.

How does the Secure Silicon Region differ from standard sector protection?

The Secure Silicon Region is a dedicated 128-word (256-byte) area that can be permanently locked via command sequence and PPB bit, preventing any further writes or erases - unlike standard sector protection, which remains reversible via unlock commands. Once locked, this region retains its contents for 20 years and is inaccessible to standard erase commands, even during chip erase.

Is the 70 ns access time guaranteed across the full industrial temperature range?

Yes - the 70 ns access time is specified and tested over the full –40°C to +85°C industrial temperature range at V_CC = 3.0 V ±0.3 V and specified capacitive load. This timing includes address setup and hold margins and is validated per JEDEC JESD22-A108 reliability standards, ensuring deterministic boot performance in uncontrolled thermal environments.
