Infineon Technologies S29GL256P90FACR10

Overview

S29GL256P90FACR10 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 and 25 ns page access time, features a 32-word/64-byte write buffer and uniform 64 Kword sectors (256 total), and operates across industrial temperature range (–40°C to +85°C) in a 64-ball Fortified BGA package. It is used in embedded boot code storage for industrial controllers and network edge devices requiring reliable nonvolatile program storage.

For engineers reviewing the S29GL256P90FACR10 datasheet, S29GL256P90FACR10 pinout, S29GL256P90FACR10 application, or S29GL256P90FACR10 equivalent, key selection criteria include sector erase endurance (100,000 cycles), data retention (20 years), VersatileI/O™ voltage flexibility (VIO = 1.65–VCC), CFI compliance, and hardware-accelerated programming via WP#/ACC.

Technical Context

This device implements a synchronous-compatible asynchronous interface with dedicated CE#, OE#, and WE# controls, supporting byte/word configuration via BYTE# input and hardware reset via RESET#. Its internal state machine handles embedded program/erase algorithms, with RY/BY# signaling completion and suspend/resume capability for both operations.

The Secured Silicon Sector provides 128-word (256-byte) factory- or customer-programmable space with lockable Electronic Serial Number, while Advanced Sector Protection supports both persistent bit and password-based locking. Power management includes 1 µA standby current and automatic sleep mode.

FAQ

What is the function of the VIO pin on S29GL256P90FACR10?

The VIO pin sets the logic threshold for all address, control, and data I/O pins independently of VCC. With VIO ranging from 1.65 V to VCC (2.7–3.6 V), it allows direct interfacing with 1.8 V or 2.5 V host processors without external level shifters - a key enabler for mixed-voltage system design and power optimization.

Does S29GL256P90FACR10 support hardware reset, and how does it behave?

Yes, the RESET# pin provides asynchronous hardware reset. When asserted low, it immediately terminates any active program or erase operation, clears internal command registers, and returns the device to reading array data mode. The pin has internal pull-up, so it defaults to inactive (high) when unconnected - ensuring safe power-on behavior.

How does the Secured Silicon Sector work, and who can program it?

The Secured Silicon Sector is a dedicated 128-word (256-byte) region containing an 8-word (16-byte) factory-programmed Electronic Serial Number. Both factory and end customer can program and permanently lock this region using dedicated command sequences. Once locked, contents are immutable and immune to bulk erase - enabling secure device identification and anti-cloning.

Can S29GL256P90FACR10 be used in place of older S29GL256N devices?

No - S29GL256P90FACR10 is not a drop-in replacement for S29GL256N. While both are 256 Mbit NOR Flash, the P-series uses 90 nm MirrorBit technology with different timing (90 ns vs. 110 ns), enhanced VersatileI/O™, and updated command set. Pin compatibility exists, but timing margins, VIO dependency, and protection register layout require full validation before substitution.
