Infineon Technologies IS29GL128S-10TFV01

Overview

IS29GL128S-10TFV01 from Infineon is a 128 Mb (16 MB), 3.0 V core, parallel-interface MIRRORBIT™ Eclipse flash memory with ×16 data bus, 90 ns random access time, 15 ns page access time, and industrial temperature grade (–40°C to +85°C). It integrates hardware ECC for single-bit error correction, 128-kbyte uniform sectors, and a 512-byte programming buffer-enabling fast embedded code storage and firmware updates in microcontroller boot loaders.

For engineers reviewing the IS29GL128S-10TFV01 datasheet, IS29GL128S-10TFV01 pinout, IS29GL128S-10TFV01 application, or IS29GL128S-10TFV01 equivalent, key selection criteria include asynchronous read timing, Versatile I/O voltage range (1.65 V to VCC), sector erase endurance (100,000 cycles), OTP array support, and CFI-compliant interface compatibility with legacy NOR-based boot architectures.

Technical Context

This device implements an asynchronous parallel NOR flash architecture with XIP-capable random and page-mode reads. Its embedded algorithm controller handles program/erase operations autonomously, while internal hardware ECC corrects single-bit errors on-the-fly during read cycles without host intervention.

The 128-kbyte uniform sector layout supports fine-grained firmware partitioning, and the 512-byte write buffer enables burst programming at up to 1.5 MBps. Sector protection includes volatile and non-volatile lock bits per sector, plus a dedicated 1024-byte OTP array with two independently lockable regions for secure configuration or calibration data.

FAQ

Does IS29GL128S-10TFV01 support execute-in-place (XIP) operation?

Yes. The device supports true XIP with 90 ns random access time and 15 ns page-mode reads, allowing microcontrollers to fetch and execute instructions directly from flash without copying to RAM. Its asynchronous interface and deterministic timing comply with ARM AMBA and legacy bus protocols for seamless integration into boot ROM subsystems.

What is the purpose of the 1024-byte OTP array?

The OTP array contains two independently lockable 512-byte regions used to store immutable data such as factory calibration coefficients, cryptographic keys, or regulatory compliance identifiers. Once locked via dedicated commands, contents cannot be erased or rewritten-even with full device unlock-ensuring permanent integrity of critical system parameters.

How does hardware ECC function during normal read operations?

Hardware ECC runs transparently on every read access: the device automatically detects and corrects single-bit errors in real time using internal syndrome calculation and bit-flip correction logic. No host intervention or additional read cycles are required, and corrected data is delivered to the bus while uncorrectable multi-bit errors trigger status register flags for host exception handling.

Can IS29GL128S-10TFV01 operate with VIO = 1.8 V while VCC = 3.3 V?

Yes. Its Versatile I/O feature supports VIO from 1.65 V to VCC, enabling direct connection to 1.8 V logic families (e.g., FPGA I/O banks or low-voltage MCUs) while maintaining 3.3 V core operation. This eliminates external level shifters and reduces BOM count and board area in mixed-voltage embedded systems.
