Product details

Overview

S29GL064N90FFIS32 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 firmware storage with hardware write protection.

For engineers reviewing the S29GL064N90FFIS32 datasheet, S29GL064N90FFIS32 pinout, S29GL064N90FFIS32 application, or S29GL064N90FFIS32 equivalent, key selection criteria include JEDEC-compliant command set, VIO-referenced VersatileI/O™ operation (1.65–3.6 V), Secured Silicon Sector with factory-programmed 128-word ESN, and support for Program/Erase Suspend & Resume in real-time firmware update scenarios.

Technical Context

This device uses 110 nm MirrorBit process technology to enable simultaneous hot-hole erase and hot-electron programming across full sectors. 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-eliminating external address/data bus hold requirements during erase/program execution.

The device supports dual-bus configuration via BYTE# input, enabling 16-bit or 8-bit data width operation. Hardware features include WP#/ACC pin for accelerated programming and first/last sector protection, RESET# for operation termination and system boot synchronization, and RY/BY# output for cycle completion detection without polling overhead.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory size	64 Mbit (4,194,304 × 16-bit words); enables storage of full boot images and application firmware in space-constrained embedded controllers.
Access time	90 ns at VCC = 2.7–3.6 V; meets timing requirements for direct execution from flash (XIP) in ARM Cortex-M and similar MCUs.
Erase endurance	100,000 cycles per sector; supports field firmware updates over 10+ years in industrial gateways and PLCs.
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 and FPGAs.
Page read buffer	8-word (16-byte) buffer with 25 ns page access; reduces sequential read latency in bootloader initialization sequences.
Write buffer	16-word (32-byte) buffer; cuts multi-word programming time by >40% versus single-word writes in firmware patching.

Pinout & Package

Package: 48-pin TSOP (Type I, standard thin small outline package), 12 × 20 mm body, lead pitch 0.5 mm. Pin count and layout conform to JEDEC MO-142AC specification.

Pin/Terminal	Circuit Role	Design Meaning
A0–A21	Address inputs	22-bit address bus supporting full 4M-word addressing; A21 selects upper/lower 32 Mbit half for banked access.
DQ0–DQ15	Data I/O bus	16-bit bidirectional data path; DQ15 also functions as A−1 for byte-mode addressing when BYTE# = low.
CE#	Chip enable	Active-low chip select; device enters standby mode when CE# high, reducing current to 1 µA.
OE#	Output enable	Controls data bus drivers during read; decouples read timing from CE# assertion for flexible bus arbitration.
WE#	Write enable	Initiates command latching and internal write operations; must be strobed with valid address/data per JEDEC timing.
WP#/ACC	Write protect / accelerate	Low = hardware sector lock; high + VHH = 2× faster programming; protects boot sector even during ACC mode.
RY/BY#	Ready/Busy indicator	Open-drain active-low output signaling active erase/program; eliminates need for DQ6/DQ7 polling in time-critical systems.
RESET#	Hardware reset	Aborts ongoing operation and returns device to read mode; synchronizes with system power-on reset for deterministic boot.
BYTE#	Bus width select	Low = 8-bit mode (DQ0–DQ7 only); high = 16-bit mode; enables compatibility with legacy 8-bit microcontrollers.
VIO	I/O voltage reference	Sets input threshold and output drive level independently of VCC; enables interfacing to 1.8 V or 3.3 V logic without level shifters.

Key Features

Feature	Design Value
Secured Silicon Sector	128-word (256-byte) factory-locked region with 8-word ESN; provides immutable device identity for secure boot and anti-cloning.
Advanced Sector Protection	Persistent and Password Sector Protection modes; prevents unauthorized firmware modification without physical access or known password.
Program/Erase Suspend & Resume	Pause erase/program in one sector to read/program another; enables concurrent firmware update and runtime diagnostics in safety-critical systems.
CFI compliance	JEDEC JESD68-defined Common Flash Interface; allows host BIOS or bootloader to auto-detect geometry, timing, and protection status.
Unlock Bypass mode	Two-cycle command sequence replaces four-cycle standard programming; reduces firmware update time by up to 35% in production flashing.

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 64 Mbit density and 90 ns speed, but 56-pin TSOP package with different pinout (e.g., NC pins at positions 1–2, 55–56) and no BYTE# pin.	Lacks byte-mode flexibility; requires PCB redesign for 16-bit-only interfaces; suitable only where board space permits larger TSOP footprint.	Select when existing design uses 56-pin socket and does not require 8-bit bus operation.
MX29GL640EHT2I-90G	64 Mbit, 90 ns, but uses Macronix's MXSMIO interface instead of JEDEC command set; no CFI support; different unlock sequence and sector map.	Not software-compatible; requires full firmware driver rewrite; lacks Secured Silicon Sector and Password Protection features.	Select only for cost-sensitive, non-security-critical applications where vendor lock-in is acceptable and driver development resources exist.

Compared with S29GL064S90TFI020, the S29GL064N90FFIS32 offers byte-mode flexibility and smaller 48-pin footprint; versus MX29GL640EHT2I-90G, it delivers certified security features, JEDEC interoperability, and field-proven reliability in safety-critical deployments.

FAQ

Is S29GL064N90FFIS32 compatible with legacy Cypress S29GL064N designs?

Yes-this part retains identical electrical specifications, pinout, command set, and timing parameters as the original Cypress S29GL064N. Infineon maintains full backward compatibility, including identical AC/DC characteristics, CFI structure, and sector protection behavior. No hardware or firmware changes are required for drop-in replacement in existing designs.

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

In normal operation, asserting WP# low permanently locks the first or last sector against erase/program commands regardless of software protection settings. During accelerated programming, applying VHH (≈12 V) to ACC while WP# is high enables faster write cycles-reducing typical programming time by ~50%-without compromising sector lock integrity.

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

Yes-the Secured Silicon Sector can be programmed and locked by the customer using the documented Enter/Exit Secured Silicon Sector command sequence. Once locked via the PPB Lock Bit, the 128-word region becomes permanently read-only, preserving factory or customer-defined identifiers, keys, or calibration data across all subsequent power cycles.

How does Program Suspend differ from Erase Suspend in practical firmware update workflows?

Program Suspend allows reading other sectors while a multi-word program operation is active-enabling background diagnostics during firmware patching. Erase Suspend pauses a sector erase to permit immediate reads or programming elsewhere-critical for maintaining real-time system responsiveness during full-image updates without halting application execution.
