Infineon Technologies S29GL256P90FFCR13

Overview

S29GL256P90FFCR13 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 S29GL256P90FFCR13 datasheet, S29GL256P90FFCR13 pinout, S29GL256P90FFCR13 application, or S29GL256P90FFCR13 equivalent, key selection criteria include sector architecture uniformity (256 × 64 Kword sectors), VersatileI/O™ voltage flexibility (VIO = 1.65–VCC), Secured Silicon Sector with factory-programmable ESN, and support for CFI-compliant host interfaces.

Technical Context

This device implements a synchronous/asynchronous hybrid command interface with embedded program/erase algorithms, hardware reset (RESET#), and Ready/Busy# status signaling. Its VersatileI/O™ architecture decouples I/O voltage (VIO) from core supply (VCC), enabling interoperability with 1.8 V, 2.5 V, or 3.3 V controllers while maintaining 2.7–3.6 V VCC operation.

The memory employs uniform 64 Kword (128 KB) sector erase architecture, supports suspend/resume during program/erase cycles, and integrates dual protection methods-Persistent Protection Bits and Password-based Advanced Sector Protection-to secure critical firmware regions against accidental or malicious overwrite.

FAQ

What is the function of the VIO pin on the S29GL256P90FFCR13?

The VIO pin sets the input/output voltage reference independently from VCC, allowing the device to interface with 1.65–VCC logic levels-including 1.8 V or 2.5 V controllers-while operating its core at 2.7–3.6 V. This eliminates level-shifter requirements in mixed-voltage systems and ensures signal integrity across diverse host platforms.

Does the S29GL256P90FFCR13 support hardware reset during active programming?

Yes. The RESET# pin provides asynchronous hardware reset: asserting it low immediately halts any ongoing program or erase operation, clears internal state machines, and returns the device to read mode. This is critical for system recovery after power glitches or watchdog timeouts without risking memory corruption.

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

The Secured Silicon Sector is a dedicated 128-word (256-byte) region with factory-programmable 8-word electronic serial number and independent lock mechanism. Once locked-either at factory or by customer-it becomes permanently read-only and immune to standard erase commands, providing tamper-resistant identity storage for licensing or anti-cloning.

Can the S29GL256P90FFCR13 be used in place of older S29GL256N devices?

No direct drop-in replacement: S29GL256P uses 90 nm MirrorBit process with enhanced VersatileI/O™, write buffer, and CFI support, whereas S29GL256N is 110 nm with different timing and command set. Pin compatibility exists, but firmware must be updated to accommodate new status bit definitions, suspend/resume commands, and VIO dependency.
