Product details

Overview

S29GL064S90FHI020 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 supports industrial temperature range (–40°C to +85°C) in 48-lead TSOP package.

For engineers reviewing the S29GL064S90FHI020 datasheet, S29GL064S90FHI020 pinout, S29GL064S90FHI020 application, or S29GL064S90FHI020 equivalent, this device serves as boot code storage in automotive ECUs, firmware retention in industrial PLCs, and configuration memory in telecom baseband processors - where deterministic read latency, sector-level erase control, and AEC-Q100 Grade 3 compliance are required.

Technical Context

The S29GL064S90FHI020 implements MIRRORBIT™ floating-gate architecture on 65-nm process, enabling hot-electron programming and hot-hole assisted sector erase. It uses JEDEC-standard command set with CFI support, and integrates dedicated status monitoring via DQ6/DQ7 polling and RY/BY# output.

Its flexible I/O interface operates with VIO from 1.65 V to VCC, allowing mixed-voltage system interfacing. The device supports both word (16-bit) and byte (8-bit) modes via BYTE# input, and includes hardware reset (RESET#), write protect (WP#/ACC), and automatic sleep mode triggered by address stability or CE#/RESET# voltage thresholds.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	64 Mb (8 MB), organized as 4,194,304 × 16-bit words - supports full firmware image storage for mid-complexity microcontrollers.
Access Time	70 ns at VCC = 3.0 V ± 0.3 V - enables direct execution (XIP) from flash in real-time control loops without wait states.
Erase Endurance	100,000 cycles per sector - suitable for field-upgradable firmware partitions updated monthly over 8+ years.
Data Retention	20 years typical at 85°C - ensures long-term reliability in uncooled industrial enclosures.
ECC Capability	Internal hardware single-bit error correction - eliminates need for external ECC logic in safety-critical boot memory paths.
Operating Temp	–40°C to +85°C (Industrial) - qualified per AEC-Q100 Grade 3, validated for automotive body control modules.
Package	48-lead TSOP (Type I, 12 × 20 mm) - compatible with standard 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-142AC compliant. Pin 1 marked by notch or dot; leads are gull-wing, surface-mountable.

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, ignored in byte mode when BYTE# = low.
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 high; required assertion for all read/write/erase operations.
OE#	Output Enable	Active-low control for data bus drivers; allows shared bus operation with other peripherals without tristate conflicts.
WE#	Write Enable	Active-low strobe for command latching and write cycles; combined with CE# and OE# defines bus operation type (read/write/standby).
RESET#	Hardware Reset	Active-low asynchronous reset; terminates ongoing program/erase, clears internal state, and returns to reading array mode.
RY/BY#	Ready/Busy Output	Open-drain status indicator; low during active program/erase, high when ready - enables interrupt-driven firmware flow control.
WP#/ACC	Write Protect / Accelerated Program	Input with dual function: low = permanent protection of first/last sector; high + VCC ≥ 3.3 V = accelerated programming mode for production line throughput.
BYTE#	Bus Width Select	Low = 8-bit data mode (DQ0–DQ7 active); high = 16-bit mode (DQ0–DQ15 active) - enables compatibility with 8-bit and 16-bit host buses.
VCC	Core Supply	3.0 V ± 0.3 V main power; powers core logic, array, and I/O buffers - no separate VPP required for erase/program.
VIO	I/O Supply	1.65 V to VCC; sets input threshold and output drive level - decouples I/O voltage from core, enabling 1.8 V host interfacing.
VSS	Ground	Dedicated analog/digital ground pin; must be connected to system ground plane with low-inductance path to minimize noise coupling into array.

Key Features

Feature	Design Value
Secure Silicon Region	128-word (256-byte) factory-lockable area with 16-byte electronic serial number - provides immutable device identity for secure boot key binding.
Program/Erase Suspend	Allows read access to unprotected sectors during active program/erase - enables real-time diagnostics and firmware updates without halting system operation.
Unlock Bypass Mode	Reduces multi-word programming overhead from 4 to 2 write cycles per word - cuts total firmware update time by ~45% in host-controlled field upgrades.
Advanced Sector Protection	Combines persistent lock bits and password-based sector locking - prevents unauthorized modification of bootloader or calibration tables in deployed systems.
Automatic Hardware ECC	On-the-fly single-bit correction with no software intervention or latency penalty - meets ASIL-B functional safety requirements for automotive memory 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
S29GL064S90TFI020	Same die, 56-lead TSOP package with different pinout (e.g., RESET# relocated); identical timing and command set.	Requires PCB redesign due to pin count and layout mismatch; not drop-in replaceable.	Select only when board space allows larger TSOP footprint and thermal dissipation requirements exceed 48-lead limits.
MX29GL640EHTI-90G	64 Mb Macronix parallel NOR; 90 ns access time; no integrated ECC; requires external error handling logic.	Lacks hardware ECC and secure silicon region - unsuitable for ASIL-B or regulated medical firmware storage.	Consider only for cost-sensitive consumer applications where ECC is implemented in software and security is not mandated.

Compared with S29GL064S90FHI020, the S29GL064S90TFI020 offers identical functionality in a mechanically incompatible package, while the MX29GL640EHTI-90G sacrifices ECC and secure silicon to reduce unit cost - making the Infineon part uniquely suited for safety- and security-critical embedded firmware storage.

FAQ

Does S29GL064S90FHI020 support both 8-bit and 16-bit data bus configurations?

Yes. The device supports 16-bit word mode by default. When BYTE# is driven low, it switches to 8-bit mode, activating only DQ0–DQ7. This dual-mode capability allows seamless integration with both 8-bit microcontrollers and 16-bit DSPs without external data bus multiplexing logic.

What is the purpose of the WP#/ACC pin beyond write protection?

The WP#/ACC pin serves two distinct functions: at logic low, it permanently protects the first or last sector; at logic high with VCC ≥ 3.3 V, it enables accelerated programming mode, reducing individual word programming time by up to 30% during high-volume manufacturing programming.

How does the internal ECC operate during read cycles?

The hardware ECC engine automatically checks each 16-bit word read from the array. If a single-bit error is detected, it is corrected transparently before data reaches the DQ bus - no software intervention, no latency penalty, and no status flag unless uncorrectable multi-bit errors occur.

Can the Secure Silicon Region be reprogrammed after factory locking?

No. Once the Secure Silicon Region is locked via the PPB lock bit or factory programming, it becomes permanently read-only. The 128-word region retains its contents indefinitely, including the 16-byte electronic serial number, and cannot be erased or rewritten under any condition - even with elevated VCC or command sequences.
