Infineon Technologies S29GL256P11TFI010

Overview

S29GL256P11TFI010 from Cypress Semiconductor is a 256 Mbit (32 Mbyte), 3.0 V-only page-mode NOR Flash memory fabricated on 90 nm MirrorBit process technology, featuring 256 uniform 64 Kword (128 Kbyte) sectors, 25 ns page access time, and 90 ns random access time under regulated VCC. It supports VersatileI/O™ with VIO range 1.65–VCC, includes 32-word write buffer and secured silicon sector with 128-word electronic serial number, and is used in industrial embedded systems requiring reliable nonvolatile storage for firmware and configuration data.

For engineers reviewing the S29GL256P11TFI010 datasheet, S29GL256P11TFI010 pinout, S29GL256P11TFI010 application, or S29GL256P11TFI010 equivalent, key selection criteria include sector erase endurance (100,000 cycles), 20-year data retention, TSOP-56 industrial temperature operation (–40°C to +85°C), and support for CFI, suspend/resume, and dual protection methods (persistent lock bits and password).

Technical Context

This device implements a synchronous-compatible asynchronous NOR Flash architecture with dedicated X/Y decoders, on-chip voltage generators for program/erase, and state control logic managing command sequences via WE#/CE#/OE# timing. Its VersatileI/O™ interface decouples I/O voltage (VIO) from core supply (VCC), enabling interoperability with 1.8 V, 2.5 V, or 3.3 V host buses while maintaining full 3.0 V internal operation.

The 32-word write buffer enables burst programming of up to 64 bytes per command cycle, reducing effective programming time by ~75% versus single-word writes; sector erase is performed in 0.5 s typical, with status reported via RY/BY# and internal status bits. Secured Silicon Sector provides factory- or customer-programmable 256-byte region with permanent locking capability.

FAQ

What is the maximum operating temperature range for S29GL256P11TFI010?

The S29GL256P11TFI010 is rated for industrial temperature operation from –40°C to +85°C, validated across full VCC (2.7–3.6 V) and VIO (1.65–VCC) ranges. This specification is confirmed in the Ordering Information section (page 4) and Electrical Specifications (page 50) of datasheet 002-00886 Rev. *B, with derating applied only beyond these limits.

Does S29GL256P11TFI010 support both byte and word data access modes?

Yes, the device supports configurable bus width via the BYTE# input: at VIL, it operates in byte mode with DQ0–DQ7 active and DQ15/A-1 repurposed as LSB address; at VIH, it operates in word mode with full 16-bit DQ0–DQ15 data path. This is defined in Section 2 (Input/Output Descriptions) and supported by the A-1 address multiplexing function.

How does the Secured Silicon Sector function in S29GL256P11TFI010?

The Secured Silicon Sector is a dedicated 128-word (256-byte) region that can store an 8-word electronic serial number and be permanently locked by the factory or end user. Once locked, contents cannot be erased or rewritten. Entry/exit is controlled by specific command sequences documented in Section 10, and the sector resides at a fixed physical location outside the main array.

Is the S29GL256P11TFI010 pin-compatible with earlier S29GL-P generations?

No, the S29GL256P11TFI010 is not pin-compatible with prior S29GL-P variants using different speed grades or packages. While the TSOP-56 footprint is consistent across the family, pin functions such as VIO and WP#/ACC require correct voltage-level handling per the VersatileI/O™ specification; migration from non-VIO parts demands board-level signal routing and voltage rail validation.
