Product details

Overview

S29GL064S70DHI020 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 S29GL064S70DHI020 datasheet, S29GL064S70DHI020 pinout, S29GL064S70DHI020 application, or S29GL064S70DHI020 equivalent, this device supports boot code storage, firmware update in embedded controllers, and secure configuration data retention in automotive and industrial systems requiring JEDEC-compliant parallel flash with persistent sector protection.

Technical Context

The S29GL064S70DHI020 implements MIRRORBIT™ charge-trapping technology on a 65-nm process, enabling simultaneous hot-hole erase and hot-electron programming. Its architecture includes dedicated command registers for unlock bypass, program/erase suspend/resume, and CFI-compliant identification.

It supports 16-bit word-wide data bus with BYTE# control for optional 8-bit mode, uses VIO-referenced I/O (1.65 V to VCC), and integrates low-VCC detection, hardware RESET#, and RY/BY# status signaling - all compliant with JEDEC Standard JESD21-C for single-power-supply flash.

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 typical at VCC = 2.7–3.6 V; defines maximum read latency for real-time boot code fetch
Write Buffer Size	128-word (256-byte) page buffer; reduces multi-word programming overhead by >50% vs. byte-by-byte writes
ECC Support	On-die hardware ECC with automatic single-bit correction; eliminates need for external error-handling logic
Endurance	100,000 erase cycles per sector minimum; ensures long-term field reliability in firmware update partitions
Data Retention	20 years typical at 85°C; validated for automotive ECU and industrial PLC storage without refresh
Operating Temp	–40°C to +85°C (Industrial grade); qualified per AEC-Q100 Grade 3 for under-hood automotive use
VIO Range	1.65 V to VCC; enables interoperability with mixed-voltage host interfaces (e.g., 1.8 V I/O with 3.0 V core)

Pinout & Package

Package: 48-lead TSOP (Type I, 12 mm × 20 mm × 1.2 mm, standard JEDEC MO-142AB). Pinout validated per Infineon datasheet Rev. *K, pages 11–12 and Figure 3.1.

Pin/Terminal	Circuit Role	Design Meaning
A0–A22	Address Inputs	23-bit address bus supporting full 4-Mword addressing; A0 selects LSB in 16-bit mode
DQ0–DQ15	Data I/O Bus	16-bit bidirectional data path; BYTE# controls 8-bit mode (DQ0–DQ7 only)
CE#	Chip Enable	Active-low chip select; must be asserted before WE# or OE# for valid bus cycle
OE#	Output Enable	Controls output drivers during read; independent of CE# for multiplexed bus sharing
WE#	Write Enable	Latches address/data on rising edge; initiates command sequences when CE# and OE# are high
RESET#	Hardware Reset	Asynchronous active-low reset; terminates ongoing program/erase and restores read mode
RY/BY#	Ready/Busy Output	Open-drain status flag; low during internal operations, high when ready for next command
WP#/ACC	Write Protect / Accelerated Program	Low = protects first/last sector; high + 5.5 V = enables accelerated programming for production
VIO	I/O Supply Reference	Sets input threshold and output voltage level; decoupled from VCC for mixed-signal interface flexibility

Key Features

Feature	Design Value
Secure Silicon Region	128-word (256-byte) factory-locked area with 16-byte electronic serial number; prevents post-deployment modification of boot keys or calibration data
Program/Erase Suspend	Allows read access to unprotected sectors during active program/erase; enables real-time diagnostics without halting firmware updates
Unlock Bypass Mode	Reduces multi-word programming to two write cycles per word instead of four; cuts total update time by ~40% in bootloader applications
Persistent Sector Protection	Non-volatile lock bits disable program/erase permanently per sector; replaces legacy 12 V protection and eliminates external hardware dependency
CFI Compliance	JEDEC-standard Common Flash Interface allows automatic device detection and parameter readout by host BIOS or bootloader without hard-coded timing

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
S29GL064S90DHI020	90 ns access time, same density/package; lower speed grade with reduced power consumption (20 mA read current)	Suitable for cost-sensitive industrial HMIs where boot latency < 90 ns is acceptable	Select when system timing margin allows slower access and lower active power is prioritized
MX29GL640EHTI-90G	Micron 64 Mb parallel NOR; 90 ns access, no integrated ECC, requires external error handling logic	Used in legacy designs lacking ECC requirements; lacks Secure Silicon Region and password protection	Choose only if existing design already implements software ECC and does not require factory-serialized secure storage

Compared with S29GL064S90DHI020 and MX29GL640EHTI-90G, the S29GL064S70DHI020 delivers tighter 70 ns timing for deterministic boot, on-die ECC to reduce BOM count, and factory-locked Secure Silicon Region - making it optimal for new automotive and medical designs requiring security, speed, and long-term reliability.

FAQ

What is the function of the WP#/ACC pin on S29GL064S70DHI020?

The WP#/ACC pin serves dual functions: when held low, it hardware-protects the first or last sector regardless of software protection settings; when driven to 5.5 V during programming, it enables accelerated program mode for faster factory programming. This pin is electrically isolated from VCC and operates independently of the 3.0 V core supply.

Does S29GL064S70DHI020 support 8-bit data bus operation?

Yes, it supports 8-bit mode via the BYTE# input pin. When BYTE# is low, only DQ0–DQ7 are active for data transfer, and the device interprets addresses accordingly. This mode maintains full command compatibility and sector protection functionality, enabling integration with 8-bit microcontrollers without glue logic.

How is the Secure Silicon Region programmed and locked?

The Secure Silicon Region is pre-programmed at the factory with a unique 16-byte electronic serial number and can be customer-locked using the Enter Secure Silicon Region command followed by the Program Command. Once the PPB lock bit is set, the region becomes permanently read-only and immune to further erase or program commands, even under accelerated voltage conditions.

What voltage ranges apply to VIO and VCC for reliable operation?

VCC must be maintained between 2.7 V and 3.6 V for all operations including read, program, and erase. VIO may range from 1.65 V to VCC, allowing flexible interfacing with 1.8 V or 3.3 V host logic while maintaining correct input thresholds and output drive levels - verified across the full industrial temperature range.
