Product details

Overview

S29GL064N90DFI020 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 boot code storage in embedded systems requiring nonvolatile program storage with hardware reset and sector-level protection.

For engineers reviewing the S29GL064N90DFI020 datasheet, S29GL064N90DFI020 pinout, S29GL064N90DFI020 application, or S29GL064N90DFI020 equivalent, key selection criteria include JEDEC-compliant command set, VIO-referenced VersatileI/O™ operation (1.65–3.6 V), CFI interface support, Secured Silicon Sector with factory-programmed 128-word ESN, and hardware write protection via WP#/ACC.

Technical Context

This device uses 110 nm MirrorBit process technology to enable simultaneous hot-hole assisted erase and hot-electron injection programming across 64 MB of NOR Flash. Its architecture integrates dedicated erase voltage and program voltage generators, state control logic, and a command register that latches addresses/data internally during write cycles.

The S29GL064N90DFI020 supports both uniform and boot-sector configurations, though this specific part number maps to the uniform 128-sector model. It features dual-mode operation: standard read/write/erase and advanced suspend/resume modes for concurrent sector access-enabling program or erase operations to be paused for reads in other sectors.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	64 Mbit (4,194,304 × 16-bit words); enables full firmware image storage for mid-complexity microcontrollers.
Access Time	90 ns at VCC = 2.7–3.6 V; ensures deterministic timing for real-time boot code fetch in industrial controllers.
Erase Endurance	100,000 cycles per sector; supports field firmware updates over 10+ years in deployed equipment.
Data Retention	20 years at 125 °C; validated for automotive under-hood and industrial high-temperature environments.
VIO Range	1.65–3.6 V; allows I/O voltage scaling independent of VCC, simplifying interface to mixed-voltage SoCs.
Page Read Buffer	8-word (16-byte); reduces sequential read latency by eliminating address setup overhead per word.
Write Buffer Size	16-word (32-byte); cuts multi-word programming time by batching writes without host intervention.
Secured Silicon Sector	128-word (256-byte) factory-lockable region; stores immutable device ID, calibration data, or cryptographic keys.

Pinout & Package

Package: 48-pin TSOP (Standard Thin Small Outline Package), compliant with JEDEC MO-142AC. Pin count and layout match industry-standard 16-bit NOR Flash footprint for drop-in compatibility in legacy designs.

Pin/Terminal	Circuit Role	Design Meaning
A0–A21	Address Inputs	22-bit address bus supporting full 4M-word addressing; A-1 used for DQ15 multiplexing in x16 mode.
DQ0–DQ15	Data/Address Multiplexed I/O	16-bit bidirectional data bus; DQ15 functions as A-1 during address phase in x16 configuration.
CE#	Chip Enable	Active-low chip select; enables device decoding in multi-chip memory maps; must be stable before WE#/OE# assertion.
OE#	Output Enable	Controls output buffer; allows read data to appear on DQ pins without asserting CE#, enabling shared-bus arbitration.
WE#	Write Enable	Initiates command latching or data programming; low pulse width and setup/hold times defined per AC spec.
WP#/ACC	Write Protect / Accelerated Program	Low = hardware sector lock (first/last sector); high + VHH = accelerated programming for production throughput.
RY/BY#	Ready/Busy Output	Open-drain status signal; low during active program/erase; used for hardware polling instead of software bit-checking.
RESET#	Hardware Reset	Aborts all operations and returns device to read mode; tied to system reset to ensure clean boot sequence.
BYTE#	Bus Width Select	High = x16 mode; low = x8 mode using DQ0–DQ7 only; enables flexible interface to 8-bit or 16-bit hosts.
VIO	I/O Voltage Reference	Sets input threshold and output swing for all control and data pins; decoupled from VCC for mixed-signal interfacing.

Key Features

Feature	Design Value
CFI Compliance	Enables automatic device identification and parameter retrieval by host BIOS/firmware without hard-coded timing tables.
Program/Erase Suspend	Allows interruption of active programming or erasing to service higher-priority reads elsewhere-critical for real-time OS boot loaders.
Advanced Sector Protection	Combines persistent lock bits and password-based sector locking to prevent unauthorized firmware modification in certified devices.
Unlock Bypass Mode	Reduces multi-word programming overhead from four to two write cycles per data word, accelerating field update deployment.
Hardware Data Protection	Integrated low-VCC detector disables writes during power ramp-up/down, preventing corruption during brown-out conditions.
Secured Silicon Sector	Factory-programmed 128-word area with permanent lock; used for storing immutable device serial numbers or cryptographic roots of trust.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NOR Flash memory applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL064S90TFI020	Same density and speed, but 56-pin TSOP package with different pinout (e.g., NC pins at positions 1–2, 55–56); no BYTE# pin-x16-only interface.	Requires PCB redesign due to pin count and signal mapping differences; lacks byte-width flexibility.	Select when board space permits larger TSOP and x16-only interface suffices; avoid if 8-bit host or footprint compatibility is required.
MX29GL640EHT2I-90G	64 Mbit, 90 ns, but uses Macronix's MX29GL architecture; different command set (non-CFI-compliant), no Secured Silicon Sector, no VIO pin.	Not suitable for CFI-dependent BIOS or systems requiring factory-programmed ESN; requires custom driver adaptation.	Consider only for cost-sensitive, non-certified applications where firmware update security and standardized enumeration are not required.

Compared with S29GL064S90TFI020 and MX29GL640EHT2I-90G, the S29GL064N90DFI020 uniquely combines CFI compliance, VIO-referenced I/O, and Secured Silicon Sector-making it the only choice for safety-certified, field-upgradable, and vendor-agnostic embedded boot memory designs.

FAQ

Is S29GL064N90DFI020 compatible with legacy Cypress S29GL064N designs?

Yes-this part retains identical electrical characteristics, pinout, command set, and timing specifications as the original Cypress S29GL064N. Infineon maintains full backward compatibility, including identical AC/DC parameters, CFI responses, and sector architecture. No firmware or hardware modifications are required for migration.

What is the function of the WP#/ACC pin in normal operation versus accelerated programming?

In normal operation, pulling WP#/ACC low permanently protects the first or last sector from accidental erase/write. When driven high with an external 5.5 V VHH supply (via charge pump), it activates accelerated programming mode-reducing individual word programming time by ~40% for high-throughput manufacturing.

Does the Secured Silicon Sector support customer programming after factory shipment?

Yes-the 128-word Secured Silicon Sector can be programmed and locked by the customer using documented command sequences. Once locked via PPB (Persistent Protection Bit), the sector becomes permanently read-only; unlocking requires physical device replacement, ensuring irreversible security for keys or IDs.

How does the device handle power loss during erase or program operations?

The S29GL064N90DFI020 includes hardware data protection: its internal low-VCC detector automatically suspends all write operations when supply drops below 2.5 V, preventing partial writes or sector corruption. Upon power restoration, the device resumes in read mode-no recovery sequence is needed.
