Product details

Overview

S29GL064S90DHVV20 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 industrial temperature range (–40°C to +85°C) in 48-lead TSOP package.

For engineers reviewing the S29GL064S90DHVV20 datasheet, S29GL064S90DHVV20 pinout, S29GL064S90DHVV20 application, or S29GL064S90DHVV20 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, high-reliability parallel flash.

Technical Context

The S29GL064S90DHVV20 implements MIRRORBIT™ charge-trapping technology on a 65-nm process, enabling simultaneous hot-hole erase and hot-electron programming. Its sector architecture comprises 128 uniform 64-KB sectors, each independently erasable without affecting others.

It supports dual-mode I/O via VIO (1.65 V to VCC), enabling flexible interface voltage scaling. Command execution follows JEDEC JESD21-C standard, with status monitoring via DQ6 toggle bit, DQ7 polling, and RY/BY# output - all synchronized to CE#, WE#, and OE# control timing.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	64 Mb (4,194,304 words × 16 bits), organized as 128 × 64-KB uniform sectors
Access Time	70 ns - enables direct execution (XIP) from flash in microcontroller boot sequences
Write Buffer Size	128 words (256 bytes) - reduces multi-word programming overhead by >60% vs. single-word writes
ECC Capability	Internal hardware single-bit error correction - eliminates need for external ECC logic in safety-critical firmware storage
Endurance	100,000 erase/program cycles per sector - supports field firmware updates over 10+ year product lifecycle
Data Retention	20 years typical at 85°C - validated for automotive ECU and industrial PLC nonvolatile storage
Operating Voltage	VCC = 2.7–3.6 V; VIO = 1.65–VCC - allows mixed-voltage system interfacing without level shifters

Pinout & Package

Package: 48-lead TSOP (Type I, 12 mm × 20 mm × 1.2 mm), RoHS-compliant, lead-free, industrial temperature grade (–40°C to +85°C).

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
DQ0–DQ15	Data I/O	16-bit bidirectional data bus; supports BYTE#-controlled 8-bit mode when asserted
CE#	Chip Enable	Active-low enable controlling device selection; must be low for read/write command latching
OE#	Output Enable	Active-low control for data bus drivers; enables read data output without affecting internal state
WE#	Write Enable	Active-low strobe that latches address/data during command sequences and programming
RY/BY#	Ready/Busy Output	Open-drain status signal indicating active program/erase cycle; used for hardware wait-state generation
RESET#	Hardware Reset	Active-low asynchronous reset that terminates ongoing operations and returns device to read mode
WP#/ACC	Write Protect / Accelerated Program	Low = protects first/last sector; high-voltage = enables accelerated programming for production throughput

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 firmware binding and anti-cloning
Program/Erase Suspend	Allows host to pause programming or erasing to service interrupts or read other sectors - essential for real-time OS boot loaders
Unlock Bypass Mode	Reduces multi-word programming command overhead from 4 to 2 write cycles - cuts firmware update time by ~35% in host-controlled flashing
Advanced Sector Protection	Persistent and password-based protection modes - enables hierarchical firmware partitioning (e.g., bootloader vs. application image)
Automatic Hardware ECC	On-the-fly single-bit correction without CPU intervention - meets ASIL-B functional safety requirements for automotive storage

Equivalent & Alternatives

The following parts are listed as comparable options for similar parallel NOR flash applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL064S90TFIR20	Same die, 56-pin TSOP package with different pinout and thermal pad; no WP#/ACC pin - lacks accelerated programming and hardware write protect	Used where board space permits larger package and production programming is handled off-system	Select only if PCB layout accommodates 56-pin footprint and system-level write protection suffices
MX29GL640EHTI-90G	64 Mb parallel NOR, 90 ns access, no integrated ECC, 100K cycles, 10-year retention - Macronix second-source part with JEDEC-compatible command set	Lower cost alternative where ECC is implemented in host MCU or external logic	Choose when BOM cost pressure outweighs ECC integration benefit and host can manage error detection

Compared with S29GL064S90DHVV20, the TSOP variant S29GL064S90TFIR20 trades hardware write protection for package size, while MX29GL640EHTI-90G sacrifices ECC and retention for cost - making the DHVV20 optimal for safety-critical, long-lifecycle designs needing on-die reliability features.

FAQ

Is S29GL064S90DHVV20 pin-compatible with earlier S29GL064N or S29GL064P devices?

No. The S29GL064S90DHVV20 uses a 48-pin TSOP package with updated pin assignments including dedicated RY/BY# and RESET# signals not present in legacy N/P series. Pin mapping differs for WP#/ACC, BYTE#, and several address lines - PCB redesign is required for migration.

Does this device support 8-bit data bus operation?

Yes. When the BYTE# input is asserted low, the device operates in 8-bit mode using DQ0–DQ7 only. The upper byte (DQ8–DQ15) is disabled, and address lines shift accordingly - enabling compatibility with 8-bit microcontrollers without external data bus multiplexing.

What is the function of the VIO pin, and how does it affect interface design?

VIO sets the input threshold and output drive voltage for all control and data pins. With VIO ranging from 1.65 V to VCC, it allows direct interfacing to 1.8 V, 2.5 V, or 3.3 V logic families without level shifters - critical for mixed-voltage SoC designs where flash shares a bus with lower-voltage peripherals.

Can the Secure Silicon Region be reprogrammed after factory locking?

No. Once the Secure Silicon Region is permanently locked via the PPB lock bit, no further writes or erases are possible - even with valid passwords or high-voltage programming. The 16-byte electronic serial number is programmed and locked at factory; customer locking is irreversible and enforced by on-die fuse circuitry.
