Product details

Overview

S29GL256P90TFCR23 from Cypress Semiconductor is a 256 Mbit (32 MB), 3.0 V-only Page Flash memory IC fabricated on 90 nm MirrorBit process technology, featuring 25 ns page access time, 90 ns random access time, and uniform 64 Kword (128 KB) sector architecture with 256 sectors. It supports VersatileI/O™ control (VIO = 1.65–VCC), 32-word write buffer programming, and Secured Silicon Sector with factory- or customer-programmable 8-word electronic serial number. Used in industrial embedded systems for firmware storage requiring high endurance and long data retention.

For engineers reviewing the S29GL256P90TFCR23 datasheet, S29GL256P90TFCR23 pinout, S29GL256P90TFCR23 application, or S29GL256P90TFCR23 equivalent, key selection considerations include VIO voltage flexibility, WP#/ACC acceleration capability, CFI compliance, suspend/resume support for real-time OS environments, and 100,000 erase cycles per sector with 20-year data retention.

Technical Context

This device implements a NOR-based page-mode flash architecture with integrated state machine control, supporting byte/word configuration via BYTE# input and hardware reset (RESET#) for system-level recovery. Its VersatileI/O™ interface decouples I/O voltage (VIO) from core supply (VCC), enabling interoperability with mixed-voltage SoCs while maintaining full 2.7–3.6 V VCC operation.

The embedded algorithm engine handles program/erase operations autonomously, exposing status via RY/BY# and internal status bits. Command execution follows Common Flash Interface (CFI) protocol, with advanced sector protection implemented through persistent lock bits and password-based software methods - not just hardware WP# assertion.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	256 Mbit (32 MB) organized as 256 × 64 Kword sectors
Page Access Time	25 ns - enables fast sequential instruction fetch from boot code regions
Random Access Time	90 ns at regulated VCC (3.0–3.6 V) - meets timing for legacy bus interfaces
Write Buffer Size	32 words (64 bytes) - reduces effective programming time by >4× vs single-word writes
Erase Endurance	100,000 cycles per sector - supports field firmware updates over product lifetime
Data Retention	20 years typical - ensures reliability in unpowered storage for industrial deployments
VIO Range	1.65 V to VCC - allows direct interfacing with 1.8 V or 3.3 V logic without level shifters

Pinout & Package

Package: 56-pin TSOP (Standard Thin Small Outline Package, TSO56), lead-free (Pb-free), industrial temperature range (–40°C to +85°C).

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MX29GL256FPTI-90G	90 nm process, same density and TSOP package, but lacks VersatileI/O™ and Secured Silicon Sector	No VIO flexibility or hardware-secured identity - requires external security layer for authentication	Select when cost sensitivity outweighs need for embedded security or mixed-voltage interface
S29GL256S90TFI02	Same Cypress family, 64-ball BGA package, identical electrical specs, but lowest-address sector protected by default	BGA footprint reduces board area; different WP# default behavior affects boot sector protection strategy	Select for space-constrained designs where BGA routing and bottom-side mounting are acceptable

Compared with MX29GL256FPTI-90G and S29GL256S90TFI02, the S29GL256P90TFCR23 uniquely combines VIO voltage adaptability, factory-lockable secure ID, and industrial-grade TSOP packaging - making it optimal for legacy bus-based systems needing both longevity and embedded security without redesign.

FAQ

What is the function of the WP#/ACC pin on the S29GL256P90TFCR23?

The WP#/ACC pin serves dual roles: at VIL, it protects the highest- or lowest-address sector (configurable by model number) from accidental program/erase; at VHH (12 V), it accelerates programming throughput and automatically enters unlock bypass mode. Internal pull-up ensures safe default VIH state when unconnected.

Does the S29GL256P90TFCR23 support byte-wide data access?

Yes - the BYTE# input selects bus width: at VIL, DQ0–DQ7 are active and DQ15/A-1 becomes A-1 (LSB address); at VIH, full 16-bit word access is enabled. This allows seamless integration with 8-bit microcontrollers or 16-bit processors without external glue logic.

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 end-user. Once locked, its contents - including an 8-word electronic serial number - become read-only and immune to standard erase commands, providing tamper-resistant device identification and cryptographic key storage.

Can the S29GL256P90TFCR23 operate with VIO = 1.8 V while VCC = 3.3 V?

Yes - VersatileI/O™ explicitly supports VIO from 1.65 V to VCC. With VCC = 3.3 V, VIO may be set to 1.8 V, allowing direct connection to 1.8 V logic families without level shifters while maintaining full 3.3 V core performance and timing specifications.
