Product details

Overview

S29GL064S80DHB020 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, industrial temperature range (–40°C to +85°C), and TSOP-48 packaging - used in boot code storage for industrial controllers and firmware update modules.

For engineers reviewing the S29GL064S80DHB020 datasheet, S29GL064S80DHB020 pinout, S29GL064S80DHB020 application, or S29GL064S80DHB020 equivalent, key selection criteria include sector architecture (uniform vs. boot), VIO voltage flexibility (1.65 V to VCC), JEDEC software compatibility, and Secure Silicon Region programmability for immutable device identity.

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 MIRRORBIT™ 65-nm process enables hot-hole erase and hot-electron programming, with automatic ECC applied per 512-byte data unit.

Hardware protection includes low-VCC write inhibition, WP#/ACC-driven first/last sector lock, and RESET#-initiated operation abort. Erase/program suspend/resume allows concurrent read access during background operations - critical for real-time firmware patching in embedded systems.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	64 Mb (4,194,304 × 16-bit words), enabling full boot image storage for mid-range microcontrollers.
Access Time	70 ns at VCC = 3.0 V ± 0.3 V, ensuring deterministic timing for legacy 8086/ARM9 bus interfaces.
Erase Cycles	≥100,000 per sector, supporting field firmware updates over 10+ years of industrial deployment.
Data Retention	20 years typical, validated under industrial temperature stress (85°C), suitable for unattended infrastructure equipment.
VIO Range	1.65 V to VCC, allowing I/O voltage scaling independent of core supply - essential for mixed-voltage SoC interfacing.
Secure Silicon Region	128-word (256-byte) factory-programmable area with permanent lock, hosting immutable serial number or cryptographic keys.
Package	48-lead TSOP (Type I, 12 mm × 20 mm), compatible with standard wave-solder reflow profiles and legacy PCB footprints.

Pinout & Package

48-lead TSOP (Thin Small Outline Package), Type I, 12 mm × 20 mm body, 0.5 mm lead pitch, JEDEC MO-141AC compliant. Pin functions validated per Infineon datasheet Rev. *K, pages 11–12.

Pin/Terminal	Circuit Role	Design Meaning
A0–A21	Address Inputs	22-bit address bus supporting full 4-Mword addressing; A0 selects LSB in word mode or byte in byte mode when BYTE# = L.
DQ0–DQ15	Data I/O	16-bit bidirectional data bus; direction controlled by WE# and OE#; supports byte-wide access when BYTE# = L.
CE#	Chip Enable	Active-low chip select; device enters standby when CE# high, reducing current to 40 µA.
OE#	Output Enable	Active-low output control; enables DQ bus drivers only during read cycles - prevents 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 returns device to read mode within 100 ns.
RY/BY#	Ready/Busy Output	Open-drain status flag; low during active program/erase, high when operation complete or in read mode.
WP#/ACC	Write Protect / Accelerated Program	Low = protects first/last sector; high + VHH = enables accelerated programming for production throughput.

Key Features

Feature	Design Value
Uniform Sector Architecture	128 × 64-KB sectors enable consistent firmware partitioning and OTA update scheduling without boot-sector complexity.
Hardware ECC Engine	On-the-fly single-bit error correction per 512-byte block eliminates need for external error-handling logic in safety-critical systems.
Program/Erase Suspend	Allows host CPU to read or program alternate sectors during long erase (up to 1 s) or program (up to 20 ms) operations - maintains system responsiveness.
Secure Silicon Region	Factory- or customer-lockable 256-byte zone stores immutable identifiers or keys, preventing cloning or unauthorized firmware replacement.
Unlock Bypass Mode	Reduces multi-word programming overhead from 4 to 2 write cycles per word, cutting total firmware write time by ~50% in host-controlled updates.

IC Role / Device Role / Timing Role: Boot memory mapped to ARM Cortex-M7 reset vector space; accessed via 16-bit parallel bus during cold start.

Use Value: Hardware RESET# integration ensures reliable recovery after brown-out; Secure Silicon Region stores unique VIN-linked calibration data.

Medical Diagnostic Equipment BIOS

Telecom Base Station Configuration Storage

Use Scenario: Stores UEFI-compatible BIOS and FPGA configuration bitstreams in portable ultrasound and MRI subsystems.

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
S29GL064S90DHB020	90 ns access time (vs. 80 ns), identical sector map, same TSOP-48 package and command set.	Lower performance grade; suitable where 70 ns timing margin is not required, e.g., slower microcontroller buses.	Select when cost sensitivity outweighs access time requirement and board layout accommodates same footprint.
MX29GL640EHT2I-90G	Micron device; 90 ns access, 64 Mb, TSOP-48, JEDEC-compatible but lacks Secure Silicon Region and hardware ECC.	No factory-programmable serial number or on-die error correction - requires external SW ECC or redundancy schemes.	Choose only if Secure Silicon and hardware ECC are not mandated, and legacy Micron ecosystem support is prioritized.

Compared with S29GL064S80DHB020, the 90 ns Infineon variant trades speed for cost in less timing-critical systems, while the Micron alternative omits security and reliability features - making the original optimal for safety- or integrity-sensitive deployments.

FAQ

What is the function of the WP#/ACC pin on S29GL064S80DHB020?

The WP#/ACC pin serves dual roles: when held low, it permanently protects the first or last 64-KB sector from program/erase operations; when driven high with elevated voltage (VHH ≈ 11.5 V), it enables accelerated programming for faster production-line firmware loading. This dual functionality is hardware-implemented and does not require command sequences.

Does S29GL064S80DHB020 support byte-wide data access?

Yes - when the BYTE# input is asserted low, the device operates in 8-bit mode using DQ0–DQ7 only, with A0 ignored. In this mode, each address accesses one byte instead of one 16-bit word. The feature is hardware-controlled and fully compatible with legacy 8-bit microprocessor buses.

How is the Secure Silicon Region programmed and locked?

The Secure Silicon Region (128 words / 256 bytes) is programmed using the Enter Secure Silicon Region command sequence (0x80 → 0x60 → 0x01), followed by standard write commands. Locking is performed via the Persistent Protection Bit (PPB) - once set, the region becomes permanently read-only and cannot be reprogrammed, even after power cycle or reset.

Can S29GL064S80DHB020 operate with VIO = 1.8 V while VCC = 3.0 V?

Yes - the VIO input sets all I/O voltage thresholds independently of VCC. With VCC = 3.0 V and VIO = 1.8 V, the device accepts 1.8 V logic levels on address, control, and data pins while maintaining full 3.0 V core operation. This enables direct interfacing with 1.8 V FPGAs or SoCs without level shifters.
