512 Mbit parallel NOR Flash for code-shadowing and firmware storage
The Infineon S29GL512T11TFIV20 is a 512 Mbit parallel NOR Flash memory from the GL-T series, organized as 64M x 8 bits. It delivers a 110 ns access time over a 1.65 V to 3.6 V supply range, making it a standard-speed parallel NOR part suited for boot code, firmware storage, and execute-in-place (XIP) applications in embedded systems. The 56-TSOP surface-mount package fits legacy and current PCB layouts that use parallel NOR for code shadowing or FPGA configuration storage.
110 ns access time — timing margin for the memory controller
The 110 ns access time is the read-cycle window the host controller must accommodate. The 60 ns write cycle time (word/page) is fast enough for firmware updates over a parallel bus without stalling the host for extended periods.
