Product details

Overview

S29GL256P90FFIR22 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. It delivers 90 ns random access time, 25 ns page access time, and features a 32-word/64-byte write buffer for accelerated multi-word programming - ideal for boot code storage and firmware updates in industrial control systems.

For engineers reviewing the S29GL256P90FFIR22 datasheet, S29GL256P90FFIR22 pinout, S29GL256P90FFIR22 application, or S29GL256P90FFIR22 equivalent, key selection criteria include uniform 64 Kword sector architecture (256 sectors), 100,000 erase cycles per sector, 20-year data retention, VersatileI/O™ support (VIO = 1.65–VCC), and CFI-compliant interface for host system compatibility.

Technical Context

This device operates in word (16-bit) or byte (8-bit) configuration via BYTE# input, with address range A23–A0 (24 address lines). Its embedded algorithms support suspend/resume during program/erase, and status reporting via RY/BY# output and internal status bits.

The WP#/ACC pin provides dual functionality: hardware write protection of top/bottom sector at VIL, and programming acceleration via VHH voltage application. Sector protection uses both persistent lock bits and password-based methods, enabling flexible field firmware security management.

Key Specifications

Parameter	Value and Actual Design Meaning
Density	256 Mbit (32 MB) organized as 256 uniform 64 Kword sectors
Access Time	90 ns random access (VCC = 3.0–3.6 V); enables fast instruction fetch in microcontroller boot sequences
Page Access	25 ns page read time supports high-throughput firmware loading from sequential memory regions
Write Buffer	32-word (64-byte) buffer reduces effective programming time to 13.5 µs/word with VHH acceleration
Erase Endurance	100,000 cycles per sector ensures long-term reliability in field-upgradable embedded systems
Data Retention	20 years typical at +85°C - validated for industrial temperature operation without refresh
VersatileI/O	VIO input (1.65–VCC) independently sets I/O voltage level, decoupling interface logic from core VCC

Pinout & Package

Package: 64-ball Fortified BGA (LAA064), 11 × 13 mm, 1.0 mm pitch, Pb-free (F), Industrial temperature (–40°C to +85°C).

Pin/Terminal	Circuit Role	Design Meaning
A23–A0	Address inputs	24-bit address bus supporting full 32 MB addressing; A23 is MSB
DQ15–DQ0	Data I/O	16-bit bidirectional data bus; DQ15/A-1 serves as LSB address in byte mode
CE#, OE#, WE#	Chip/Output/Write Enable	Standard asynchronous NOR interface controls memory access timing and direction
RY/BY#	Ready/Busy output	Active-low open-drain signal indicates active program/erase; used for polling or interrupt-driven flow control
RESET#	Hardware reset	Asynchronous active-low input that aborts ongoing operations and returns device to read mode
WP#/ACC	Write protect / acceleration	At VIL: locks top/bottom sector; at VHH: enables unlock bypass mode for faster production programming
VIO	Versatile I/O supply	Independent voltage reference (1.65–VCC) for all I/O pins - allows mixed-voltage system interfacing
BYTE#	Bus width select	Configures 8-bit (VIL) or 16-bit (VIH) data path; determines DQ15/A-1 function

Key Features

Feature	Design Value
Secured Silicon Sector	128-word (256-byte) factory- or customer-programmable region with electronic serial number for secure device identification
Suspend/Resume	Allows temporary halt of program/erase operations to service higher-priority read requests - critical for real-time OS environments
Advanced Sector Protection	Combines persistent lock bits and password-based software protection to prevent unauthorized firmware modification
CFI Support	Common Flash Interface compliance enables automatic detection and configuration by host bootloader without hard-coded parameters
Automatic Sleep Mode	Enters ultra-low-power standby (<1 µA) after 100 µs of bus inactivity - reduces system-level power consumption

Applications

Use Value: Write buffer programming (13.5 µs/word with VHH) reduces reconfiguration downtime versus standard single-word programming.

Equivalent & Alternatives

The following parts are listed as comparable options for similar page-mode NOR Flash applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL256S90TFI01	TSOP-56 package (vs. BGA); same 90 nm MirrorBit process, identical timing and command set	Preferred for prototyping or space-constrained PCBs where BGA assembly is not available	Select when manual rework or legacy board layout requires through-hole or gull-wing footprint
MX29GL256FHTI-90G	Macronix device; 90 ns access, but uses different CFI query structure and lacks VersatileI/O™ (VIO fixed to VCC)	Requires modified bootloader initialization sequence; no independent I/O voltage scaling	Choose only if existing design already uses Macronix CFI parser and VIO flexibility is not required

Compared with S29GL256S90TFI01 and MX29GL256FHTI-90G, the S29GL256P90FFIR22 uniquely supports VIO voltage decoupling (1.65–VCC), enabling direct interface to 1.8 V logic without level shifters - reducing BOM count and signal integrity risk in mixed-voltage SoC designs.

FAQ

What is the function of the VIO pin on S29GL256P90FFIR22?

The VIO pin sets the voltage level for all input and output signals (address, control, and DQ lines), independent of VCC. It accepts 1.65 V to VCC, allowing direct interface with 1.8 V, 2.5 V, or 3.3 V logic without external level shifters - a key enabler for mixed-voltage SoC designs.

Does S29GL256P90FFIR22 support hardware write protection of specific sectors?

Yes - the WP#/ACC pin provides hardware-level protection of either the highest or lowest 64 Kword sector (configurable via model number suffix). When pulled low, it disables program/erase in that sector regardless of software protection settings, offering fail-safe firmware protection during power-up or brownout conditions.

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

The Secured Silicon Sector is a dedicated 128-word (256-byte) region with factory-programmable or customer-lockable electronic serial number. Once locked, its contents cannot be erased or rewritten - providing immutable device identity for licensing, anti-counterfeiting, and secure boot chain validation in regulated environments.

Can S29GL256P90FFIR22 be used in byte-mode configuration?

Yes - asserting BYTE# low configures the device for 8-bit data bus operation, activating DQ0–DQ7 and repurposing DQ15/A-1 as the LSB address input (A-1). This mode maintains full 24-bit addressing capability and supports legacy 8-bit microcontrollers without external data bus multiplexing.
