S29GL01GT12TFVV20

Memory IC Overview

The Infineon S29GL01GT12TFVV20 is a 1 Gbit (128 MB) parallel NOR flash memory device from the GL-T MirrorBit Eclipse family. It utilizes 45-nm process technology and supports asynchronous read access with random access times of 110 ns and page access times of 25 ns. The device operates on a single 3.0 V supply (2.7 V to 3.6 V) with versatile I/O ranging from 1.65 V to VCC. It features an 8-bit or 16-bit data bus, a 512-byte write buffer for efficient programming, and uniform 128-KB sector erase architecture. The component is housed in a 64-ball LAA fortified BGA package.

Memory IC Feature Summary

• Integrates internal hardware automatic error checking and correction (ECC) capable of single-bit error correction during initial read access.
• Includes a separate 2048-byte one-time programmable (OTP) array divided into four lockable regions for secure silicon storage.
• Supports advanced sector protection (ASP) utilizing both volatile and non-volatile methods to prevent unauthorized program or erase operations.
• Features a 512-byte write buffer that enables faster effective programming by allowing bulk data writes before initiating array programming.
