Product details

Overview

S29GL064N90TFI030 from Infineon Technologies (formerly Cypress) is a 64 Mbit, 3.0 V single-power-supply MirrorBit Flash memory organized as 4,194,304 words (16-bit bus), featuring 90 ns access time, 100,000 erase cycles per sector, and 20-year data retention. It implements uniform sector architecture with 128 × 64 KB sectors and supports both standard and accelerated programming via WP#/ACC input for factory throughput.

For engineers reviewing the S29GL064N90TFI030 datasheet, S29GL064N90TFI030 pinout, S29GL064N90TFI030 application, or S29GL064N90TFI030 equivalent, key selection criteria include JEDEC-compliant command set, CFI interface support, Secured Silicon Sector with factory-programmed 128-word ESN, and hardware reset (RESET#) for boot firmware recovery in embedded systems.

Technical Context

This device uses 110 nm MirrorBit process technology to enable simultaneous hot-hole assisted erase and hot-electron injection programming. Its VersatileI/O™ control decouples I/O voltage (VIO = 1.65–3.6 V) from core supply (VCC = 2.7–3.6 V), enabling interoperability with mixed-voltage host systems.

The architecture includes dedicated status signaling via DQ7 (Data# Polling), DQ6/DQ2 (toggle bits), and RY/BY# output, alongside hardware features including low-VCC write inhibition, automatic sleep mode, and persistent sector protection with lock register control - all compliant with JEDEC JESD21-C standards.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	64 Mbit (4,194,304 × 16-bit words); enables storage of full boot code + firmware images in space-constrained embedded controllers.
Access Time	90 ns at VCC = 2.7–3.6 V; meets real-time read latency requirements for microcontroller boot sequences and firmware execution.
Erase Endurance	100,000 cycles per sector; supports field firmware updates over product lifetime in industrial gateways and networking equipment.
Data Retention	20 years at 125°C; ensures long-term reliability in automotive under-hood and industrial control applications.
Supply Voltage	VCC = 2.7–3.6 V, VIO = 1.65–3.6 V; allows direct interfacing with 1.8 V/2.5 V/3.3 V logic without level shifters.
Page Read Buffer	8-word (16-byte) buffer with 25 ns page access; accelerates sequential instruction fetch during CPU boot loading.
Write Buffer	16-word (32-byte) buffer; reduces multi-word programming overhead by batching writes and minimizing command overhead.

Pinout & Package

Package: 48-pin TSOP (Type I, standard thin small outline package, 12 × 20 mm body). Pinout validated per Cypress/Infineon Document 001-98525 Rev. *B, Figure 1 (S29GL064N Models 03/04).

Pin/Terminal	Circuit Role	Design Meaning
A0–A21	Address Inputs	22-bit address bus supporting full 4M-word addressing; A-1 (DQ15) used for x16/x8 configuration in byte mode.
DQ0–DQ15	Data/Address Multiplexed I/O	16-bit bidirectional data bus; DQ15 doubles as A-1 for byte-mode selection when BYTE# = LOW.
CE#, OE#, WE#	Chip/Output/Write Enable Controls	Independent gating enables concurrent memory mapping and eliminates bus contention in multi-peripheral systems.
WP#/ACC	Write Protect / Accelerated Program Input	Active-low hardware protection for first/last sector; high-voltage mode (ACC) cuts programming time during production burn-in.
RESET#	Hardware Reset Input	Asynchronous reset terminates ongoing erase/program and restores device to known state - critical for safe boot recovery.
RY/BY#	Ready/Busy Output	Open-drain status signal indicating active programming/erase; enables interrupt-driven host polling without constant DQ7 toggling.
BYTE#	Bus Width Configuration	Selects x16 (BYTE# = HIGH) or x8 (BYTE# = LOW) operation; supports legacy 8-bit microcontrollers without external demux.

Key Features

Feature	Design Value
Secured Silicon Sector	128-word (256-byte) factory-locked region with 8-word electronic serial number - provides immutable device identity for secure boot and anti-cloning.
Program/Erase Suspend & Resume	Allows host to pause active programming/erasing to service higher-priority reads from other sectors - essential for real-time OS firmware updates.
CFI Compliance	Common Flash Interface enables automatic device detection and parameter querying at system startup - eliminates hardcoded timing assumptions in bootloader code.
Advanced Sector Protection	Persistent and password-based protection modes allow selective locking of boot sectors and application partitions - prevents accidental overwrite during field upgrades.
Unlock Bypass Mode	Reduces multi-word programming from 4-cycle to 2-cycle command sequence - improves firmware update throughput by ~35% in production test environments.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Flash memory applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL064S90TFI020	Same density and speed, but boot-sector architecture (127 × 64 KB + 8 × 8 KB boot sectors); lacks Secured Silicon Sector.	Better suited for legacy BIOS designs requiring dedicated protected boot blocks; not suitable where ESN-based device authentication is required.	Select only if boot-sector layout matches existing PCB footprint and secure identity features are unnecessary.
MX29GL640EHTI-90G	64 Mbit, 90 ns, but uses 65 nm process; no CFI support; 10K erase cycles; no Secured Silicon or suspend/resume features.	Limited to cost-sensitive consumer electronics with short lifecycle; incompatible with CFI-aware bootloaders and secure provisioning workflows.	Use only in non-safety-critical, low-end applications where firmware update frequency and security are not design constraints.

Compared with S29GL064S90TFI020 and MX29GL640EHTI-90G, the S29GL064N90TFI030 uniquely combines uniform sector layout, CFI compliance, Secured Silicon Sector, and full suspend/resume functionality - making it the only option qualified for long-life, secure, real-time embedded firmware storage.

FAQ

What is the function of the WP#/ACC pin on S29GL064N90TFI030?

The WP#/ACC pin serves dual functions: as Write Protect (WP#) it disables programming/erasure of the first or last sector when asserted low; as Accelerated Program (ACC) input, applying 5.5 V (±0.5 V) reduces programming time by enhancing internal charge pump efficiency. Both functions operate independently of software protection settings and remain active during accelerated programming.

Does S29GL064N90TFI030 support 8-bit data bus operation?

Yes - when BYTE# is driven LOW, the device operates in x8 mode using DQ0–DQ7 as the data bus, with DQ15 functioning as A-1 for address extension. This mode maintains full command compatibility and preserves all timing specifications, enabling seamless integration with legacy 8-bit microcontrollers without external bus multiplexing.

How does the Secured Silicon Sector differ from standard flash sectors?

The Secured Silicon Sector is a dedicated 128-word (256-byte) region that can be permanently locked at factory or by customer. Once secured, it cannot be erased or reprogrammed - even with elevated voltages. It contains an 8-word electronic serial number (ESN) accessible only via defined command sequences, providing tamper-resistant device identification for secure boot and licensing.

Can S29GL064N90TFI030 be used in systems with 1.8 V I/O interfaces?

Yes - the VersatileI/O™ architecture allows VIO to operate from 1.65 V to 3.6 V independently of VCC (2.7–3.6 V). At VIO = 1.8 V, all inputs (address, control, data) recognize 1.8 V logic levels and outputs drive 1.8 V-compatible signals, eliminating need for external level shifters when interfacing with 1.8 V FPGAs or microcontrollers.
