Infineon Technologies S29GL128P11FAIV10

Overview

S29GL128P11FAIV10 from Cypress Semiconductor is a 128 Mbit (16 MB), 3.0 V-only Page Flash memory IC fabricated on 90 nm MirrorBit process technology, featuring 128 uniform 64 Kword sectors, 25 ns page access time, and 90 ns random access time. It operates across –40°C to +85°C industrial temperature range in a 64-ball Fortified BGA (LAA064) package and supports CFI, VersatileI/O™, and Secured Silicon Sector for embedded boot code storage.

For engineers reviewing the S29GL128P11FAIV10 datasheet, S29GL128P11FAIV10 pinout, S29GL128P11FAIV10 application, or S29GL128P11FAIV10 equivalent, key selection criteria include sector erase endurance (100,000 cycles), write buffer programming efficiency (64-byte burst), VIO voltage flexibility (1.65–VCC), and hardware reset/ready-busy signaling for real-time flash management in resource-constrained systems.

Technical Context

This device implements a synchronous command-set architecture with dual-mode data bus (word/byte via BYTE#), integrated erase voltage generator, and state machine-controlled embedded algorithms for program/erase. 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 logic domains while maintaining full 2.7–3.6 V VCC operation.

The Secured Silicon Sector provides factory- or customer-programmable 256-byte identification space with lockable 16-byte Electronic Serial Number, and Advanced Sector Protection supports both persistent bit locking and password-based unprotection-critical for secure firmware update and IP protection in automotive and industrial controllers.

FAQ

What is the function of the VIO pin on the S29GL128P11FAIV10?

VIO sets the input voltage thresholds and output drive levels for all address, control, and data pins independently of VCC. With VIO ranging from 1.65 V to VCC, the device interfaces directly with 1.8 V, 2.5 V, or 3.3 V logic without external level shifters-reducing BOM count and PCB complexity in mixed-voltage SoC designs.

Does the S29GL128P11FAIV10 support hardware reset during active programming?

Yes. The active-low RESET# input asynchronously terminates any ongoing program or erase operation, clears internal state machines, and returns the device to read mode within 100 ns. This feature enables safe recovery from power glitches or watchdog timeouts without risking flash corruption.

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

The Secured Silicon Sector is a dedicated 256-byte region with factory- or customer-programmable 16-byte Electronic Serial Number and lock bits. Once locked, its contents cannot be erased or rewritten-even by commands that affect other sectors-ensuring permanent device identification and cryptographic key storage for secure boot validation.

Can the S29GL128P11FAIV10 be used in byte-mode configuration?

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 mode supports 8-bit microcontrollers and simplifies interface design for legacy 8-bit bus architectures without requiring external data multiplexing.
