Infineon Technologies S29GL128P11FAI010

Overview

S29GL128P11FAI010 from Cypress Semiconductor is a 128 Mbit (16 MB) 3 V page-mode NOR Flash memory fabricated on 90 nm MirrorBit process technology, featuring 128 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, 32-word write buffer, and Secured Silicon Sector with factory- or customer-programmable 128-word serial number - deployed in industrial embedded controllers for firmware storage and field-upgradable boot code.

For engineers reviewing the S29GL128P11FAI010 datasheet, S29GL128P11FAI010 pinout, S29GL128P11FAI010 application, or S29GL128P11FAI010 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 pin for sector protection and VHH-accelerated programming.

Technical Context

This device implements a synchronous/asynchronous hybrid interface with dedicated CE#, OE#, and WE# controls, enabling direct CPU bus interfacing without glue logic. Its architecture includes an internal state machine managing embedded program/erase algorithms, suspend/resume capability, and Ready/Busy# output for real-time operation status monitoring.

The VersatileI/O™ control decouples I/O voltage (VIO) from core supply (VCC), allowing interoperability with 1.8 V, 2.5 V, or 3.3 V host systems while maintaining full 3 V core operation. Sector protection employs both persistent lock bits and password-based software methods, with WP#/ACC providing hardware-level first/last sector write protection independent of software settings.

FAQ

What is the function of the WP#/ACC pin on S29GL128P11FAI010?

The WP#/ACC pin serves two distinct roles: at VIL, it hardware-protects the top or bottom sector from program/erase operations regardless of software protection settings; when driven to VHH (~12 V), it activates unlock bypass mode, accelerating programming throughput during manufacturing. It features an internal pull-up, defaulting to VIH when unconnected.

Does S29GL128P11FAI010 support true x8/x16 bus width selection?

Yes - the BYTE# input selects bus width: at VIL, DQ0–DQ7 are active and DQ15/A-1 becomes A-1 (LSB address) for byte mode; at VIH, DQ0–DQ15 operate as a full 16-bit data bus in word mode. This dual-mode capability eliminates external bus-width translation logic in heterogeneous system designs.

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

The Secured Silicon Sector is a dedicated 128-word (256-byte) region that can be permanently locked at factory or by customer. Once locked, its contents - including an 8-word electronic serial number - cannot be erased or rewritten, even with global unlock commands. It resides outside the main array and is accessed via unique command sequences defined in the datasheet.

Can S29GL128P11FAI010 be used in systems with 1.8 V I/O interfaces?

Yes - with VIO supplied at 1.8 V and VCC at 3.0–3.6 V, the device operates in VersatileI/O™ mode, accepting 1.8 V logic levels on all address, control, and data pins while maintaining full 3 V core functionality. This enables seamless interfacing with 1.8 V FPGAs, ASICs, and low-power microcontrollers without level shifters.
