Infineon Technologies S29GL256P11FFI010

Overview

S29GL256P11FFI010 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 sectors, 25 ns page access time, and 32-word write buffer for accelerated multi-word programming. It operates across –40°C to +85°C and supports VersatileI/O™ with VIO range 1.65–VCC, making it suitable for industrial embedded storage in networking routers and automotive control modules.

For engineers reviewing the S29GL256P11FFI010 datasheet, S29GL256P11FFI010 pinout, S29GL256P11FFI010 application, or S29GL256P11FFI010 equivalent, key selection criteria include sector erase endurance (100,000 cycles), data retention (20 years), CFI compliance, hardware reset (RESET#), and dual protection modes (Persistent/Password Advanced Sector Protection).

Technical Context

This device implements a synchronous/non-volatile flash architecture with independent X/Y decoders, on-chip voltage generators for erase/program, and state control logic managing command sequences via WE#/CE#/OE# timing. It supports byte/word configuration via BYTE#, uses DQ15/A-1 as dual-role pin, and integrates a secured silicon sector with factory- or customer-programmable 128-word serial number.

Operation relies on command register latching with unlock bypass mode for accelerated programming when WP#/ACC is driven to VHH. The Ready/Busy# (RY/BY#) output provides real-time status of embedded algorithms, while CFI support enables host system auto-configuration of timing and geometry parameters.

FAQ

What is the function of the WP#/ACC pin on S29GL256P11FFI010?

The WP#/ACC pin serves dual functions: at VIL, it protects the highest or lowest address sector from accidental program/erase; at VHH (12 V), it accelerates programming by enabling unlock bypass mode, reducing single-word programming time from 60 µs to 13.5 µs. Internally pulled up, it defaults to VIH when unconnected, permitting normal operation.

Does S29GL256P11FFI010 support byte-mode operation?

Yes. When BYTE# is driven low, the device enters byte mode: DQ0–DQ7 become active data lines, and DQ15/A-1 functions as the LSB address input (A-1). This enables 8-bit microcontroller interfacing without external data bus multiplexing, preserving pin count and simplifying PCB layout for legacy 8-bit systems.

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

The Secured Silicon Sector is a dedicated 128-word (256-byte) region physically isolated from main array logic. It can be permanently locked at factory or by user to store immutable identifiers like electronic serial numbers. Unlike standard sectors, it cannot be erased or rewritten once locked, and its contents remain intact even after full chip erase commands.

Can S29GL256P11FFI010 be used with a 1.8 V I/O interface?

Yes, provided VCC is within 2.7–3.6 V and VIO is set to 1.8 V. The VersatileI/O™ architecture allows VIO to operate independently from VCC across 1.65–VCC, enabling direct connection to 1.8 V logic families without level shifters. All input thresholds and output drive strengths are referenced to VIO, ensuring signal integrity in mixed-voltage systems.
