Infineon Technologies S29GL256P11TFIV13

Overview

S29GL256P11TFIV13 from Cypress Semiconductor is a 256 Mbit (32 MB), 3.0 V-only Page Flash memory fabricated on 90 nm MirrorBit process technology, featuring 256 uniform 128 KB sectors, 25 ns page access time, and 110 ns random access time at regulated VCC. It supports VersatileI/O™ with VIO range 1.65–VCC, 32-word write buffer, and Secured Silicon Sector for factory- or customer-programmable 256-byte serial ID - deployed in industrial embedded controllers requiring nonvolatile firmware storage with sector-level protection.

For engineers reviewing the S29GL256P11TFIV13 datasheet, S29GL256P11TFIV13 pinout, S29GL256P11TFIV13 application, or S29GL256P11TFIV13 equivalent, key selection criteria include 110 ns random access timing under industrial temperature (–40°C to +85°C), TSOP-56 package compatibility, CFI-compliant interface, WP#/ACC dual-function pin behavior, and persistent/password-based Advanced Sector Protection implementation.

Technical Context

This device implements a synchronous command-set architecture with dedicated state control logic, erase voltage generator, and PGM voltage generator enabling embedded erase and program algorithms. It uses a hierarchical X/Y decoder structure with sector switches and data Y-gating to manage 256 independent 64 Kword sectors, each rated for 100,000 erase cycles and 20-year data retention.

VersatileI/O™ decouples I/O voltage (VIO) from core supply (VCC), allowing DQ, address, and control signal levels to scale from 1.65 V to VCC while maintaining full functionality across 2.7–3.6 V VCC range. The RY/BY# output provides real-time status of active Embedded Algorithms, and RESET# enables hardware-initiated return to read mode without power cycle.

FAQ

What is the function of the VIO pin on S29GL256P11TFIV13?

The VIO pin sets the input/output voltage threshold for all address, control, and data pins (A0–A23, CE#, OE#, WE#, DQ0–DQ15). It operates independently from VCC and ranges from 1.65 V to VCC, enabling direct interfacing with 1.8 V, 2.5 V, or 3.3 V host processors without external level shifters - a key differentiator from legacy parallel flash devices.

How does the Secured Silicon Sector work in practice?

The Secured Silicon Sector is a dedicated 256-byte region containing an 8-word (16-byte) Electronic Serial Number pre-programmed at the factory. Customers can permanently lock this region using a specific command sequence, preventing overwrite while retaining read access. Once locked, the serial number becomes immutable and serves as a hardware root-of-trust for device authentication and firmware binding.

Can S29GL256P11TFIV13 be used in place of older S29GL256N devices?

No - S29GL256P11TFIV13 is not pin- or command-compatible with the S29GL256N generation. The 'P' series introduces VersatileI/O™, updated CFI tables, revised command sequences (e.g., unlock bypass), and tighter AC timing. Migration requires PCB layout changes (VIO addition), firmware driver updates, and validation of all erase/program flow timing margins.

What happens when RESET# is asserted during an erase operation?

Asserting RESET# during an erase operation forces immediate termination of the embedded algorithm, clears internal state machines, and returns the device to reading array data mode. The sector being erased remains in an undefined state and must be verified and re-erased before programming - no automatic recovery or rollback occurs, making RESET# a last-resort abort mechanism.
