Infineon Technologies S29GL256P11FFIV10

Overview

S29GL256P11FFIV10 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 256 uniform 64 Kword (128 Kbyte) sectors, 25 ns page access time, and 110 ns random access time under regulated VCC conditions. It supports VersatileI/O™ with VIO range 1.65–VCC, 32-word write buffer, and Secured Silicon Sector for electronic serial number programming - deployed in industrial embedded controllers requiring nonvolatile program storage with sector-level protection.

For engineers reviewing the S29GL256P11FFIV10 datasheet, S29GL256P11FFIV10 pinout, S29GL256P11FFIV10 application, or S29GL256P11FFIV10 equivalent, key selection criteria include sector erase endurance (100,000 cycles), data retention (20 years), CFI compliance, hardware reset (RESET#), and WP#/ACC dual-function input for factory acceleration and sector write protection.

Technical Context

This device implements a synchronous/asynchronous hybrid interface with dedicated CE#, OE#, and WE# controls, supporting byte/word configuration via BYTE# input and automatic sleep mode for low-power standby (1 µA). Its internal state machine handles embedded erase and program algorithms, with RY/BY# output signaling operation completion and unlock bypass command reducing single-word programming to 60 µs.

The 64-ball Fortified BGA (LAA064) package enables high-density PCB layout while supporting both full-VCC (2.7–3.6 V) and regulated-VCC (3.0–3.6 V) operation modes. VersatileI/O™ decouples I/O voltage (VIO) from core supply (VCC), allowing interoperability with 1.8 V or 3.3 V logic systems without level shifters.

FAQ

What is the maximum operating temperature range for S29GL256P11FFIV10?

The 'I' suffix in the part number denotes Industrial temperature grade: –40°C to +85°C ambient operating range. This is validated per JEDEC JESD22-A108 and supported across all specified VCC and VIO voltage ranges. Thermal derating is not required within this envelope, and data retention remains 20 years at +85°C.

Does S29GL256P11FFIV10 support byte-level writes?

No - it supports word (16-bit) and byte (8-bit) data bus configurations via the BYTE# pin, but programming occurs in minimum units of one word (or one byte in byte mode); there is no true single-byte write capability. All writes require valid command sequences and are subject to the 32-word write buffer limit.

How is the Secured Silicon Sector programmed and locked?

The 128-word Secured Silicon Sector is programmed using standard CFI commands (e.g., Program Setup, Program Confirm) applied to addresses 0x00000000–0x000000FF. Locking is performed via the Sector Protect command (0x60 → 0xD0) followed by the appropriate sector address; once locked, the sector becomes permanently read-only and immune to erase or program commands.

Can S29GL256P11FFIV10 be used with a 1.8 V microcontroller interface?

Yes - with VIO = 1.8 V and VCC = 3.0–3.6 V (model V1/V2), all inputs accept 1.8 V logic levels and outputs drive to 1.8 V-compatible swing. The device maintains full timing specifications (110 ns random access) in this mode, eliminating need for external level shifters in mixed-voltage designs.
