Product details

Overview

S29GL256P90FFCR20 from Cypress Semiconductor is a 256 Mbit (32 MB), 3.0 V-only page-mode NOR Flash memory fabricated on 90 nm MirrorBit process technology, featuring 25 ns page access time, 90 ns random access time, uniform 64 Kword sectors (256 total), and 100,000 erase cycles per sector - deployed in industrial embedded systems for firmware storage and boot code execution.

For engineers reviewing the S29GL256P90FFCR20 datasheet, S29GL256P90FFCR20 pinout, S29GL256P90FFCR20 application, or S29GL256P90FFCR20 equivalent, key selection criteria include VersatileI/O™ voltage flexibility (VIO = 1.65–VCC), write buffer programming efficiency (64-byte burst), secured silicon sector with electronic serial number, and CFI-compliant interface for host controller compatibility.

Technical Context

This device operates as a parallel-interface NOR Flash with byte/word configuration selectable via BYTE# input, supporting both standard and accelerated programming modes using WP#/ACC at VHH. Its internal state machine handles embedded erase and program algorithms, with RY/BY# output signaling operation status.

The architecture includes an 8-word page read buffer and 32-word write buffer, enabling high-throughput data updates. Sector protection employs persistent bits and password methods, while Secured Silicon Sector provides factory- or customer-programmable 256-byte identity space with lock capability.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	256 Mbit (32 MB) organized as 256 × 64 Kword uniform sectors
Access Time	90 ns random access (VCC = 3.0–3.6 V); 25 ns page access enables burst reads
Write Buffer Size	64 bytes (32 words) - reduces effective programming time by >75% vs single-word writes
Erase Endurance	100,000 cycles per sector - supports frequent field firmware updates
Data Retention	20 years typical - ensures long-term reliability in unpowered storage
VersatileI/O Range	VIO = 1.65 V to VCC - allows interfacing with 1.8 V, 2.5 V, or 3.3 V logic without level shifters
Operating Temp	–40°C to +85°C (Industrial grade) - validated for harsh environmental deployment

Pinout & Package

Package: 64-ball Fortified BGA (LAA064, 11 × 13 mm, 1.0 mm pitch), Pb-free, industrial temperature grade.

Pin/Terminal	Circuit Role	Design Meaning
A23–A0	Address Inputs	24-bit address bus (A23–A0) selects 16 MB word locations; A-1 multiplexed on DQ15 in byte mode
DQ15–DQ0	Data I/O	16-bit bidirectional data bus; DQ15/A-1 serves as LSB address in byte mode (BYTE# = VIL)
CE#, OE#, WE#	Control Inputs	Standard parallel Flash control: chip enable, output enable, write enable - fully compliant with JEDEC standards
WP#/ACC	Protection/Accel Input	At VIL: locks top/bottom sector; at VHH: enables unlock bypass mode for faster production programming
RY/BY#	Status Output	Active-low open-drain signal indicates active erase/program; high-Z = ready for next command
RESET#	Hardware Reset	Asynchronous reset input - forces device into read array mode and aborts pending operations
VIO	I/O Supply	Independent I/O voltage reference (1.65–VCC) sets input thresholds and output drive levels

Key Features

Feature	Design Value
90 nm MirrorBit Process	Enables higher density and lower power vs prior generations; reduces die size and leakage current
Secured Silicon Sector	256-byte factory- or user-lockable region containing 16-byte electronic serial number for device authentication
Advanced Sector Protection	Persistent lock bits + password method prevent unauthorized firmware overwrite - critical for secure boot applications
Suspend/Resume Commands	Allows interrupting erase or program operations to service high-priority reads - essential for real-time OS environments
CFI Compliance	Standardized query structure enables automatic detection and configuration by host bootloader or flash utility software

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL256S90TFI01	TSOP-56 package (vs BGA); same 256 Mbit density, 90 ns speed, industrial temp	Larger footprint; easier hand-soldering and prototyping but less suitable for high-density PCBs	Select when board layout prioritizes assembly simplicity over space constraints
MX29GL256FHI-90G	Macronix part; 256 Mbit, 90 ns, 64-ball BGA, but lacks VersatileI/O and secured silicon sector	No VIO flexibility or hardware-based device ID - requires external security layer for authentication	Select when cost sensitivity outweighs need for integrated security and mixed-voltage interfacing

Compared with S29GL256S90TFI01 and MX29GL256FHI-90G, the S29GL256P90FFCR20 uniquely combines BGA miniaturization, VersatileI/O voltage adaptability, and on-chip secured silicon - making it optimal for space-constrained, security-aware, and multi-voltage industrial designs.

FAQ

What is the function of the VIO pin on the S29GL256P90FFCR20?

The VIO pin sets the input voltage thresholds and output drive levels for all address, control, and data signals. It operates from 1.65 V to VCC, enabling direct interface with 1.8 V, 2.5 V, or 3.3 V host logic without external level shifters - a key enabler for mixed-voltage system design.

Does the S29GL256P90FFCR20 support execute-in-place (XIP) operation?

Yes - its parallel NOR architecture and fast 25 ns page access time allow microprocessors to execute code directly from the flash array without copying to RAM. This reduces boot latency and eliminates SRAM dependency for initial firmware execution in resource-constrained embedded systems.

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

The Secured Silicon Sector is a dedicated 256-byte region that can be permanently locked after programming a unique 16-byte electronic serial number. Unlike standard sectors, it cannot be erased once locked - providing immutable device identification for anti-counterfeiting, license enforcement, and field unit traceability.

Can the S29GL256P90FFCR20 be used in place of older S29GL256N devices?

No - the S29GL256P uses a different command set, enhanced protection features, and updated timing parameters. While pin-compatible in the same BGA package, migration requires firmware validation due to differences in unlock bypass behavior, CFI query structure, and RY/BY# assertion timing during suspend/resume operations.
