Product details

128 Mbit parallel NOR Flash for code shadowing and data logging

The Infineon S29GL128P11TFI020 is a 128 Mbit parallel NOR Flash memory from the GL-P series, organized as 16 M x 8 bits. It operates on a 2.7 V to 3.6 V supply and delivers a 110 ns access time, making it a direct-fit storage device for embedded systems that require reliable, long-life code execution or data logging in industrial environments.

The 110 ns access time sets the read-cycle window for the host controller.

For designs that need a faster page-program cycle, the GL-S series sibling (S29GL128S10TFIV13) offers 60 ns write and 100 ns access — but the GL-P stays the lower-cost baseline for the 110 ns speed grade.

56-TSOP footprint — fits existing NOR Flash layouts

The surface-mount package is a standard TSOP footprint shared across the GL-P, GL-S, and GL-T families. Board rework and repair technicians can swap between density variants without layout changes — the 128 Mbit S29GL128P11TFI020 and the 512 Mbit S29GL512T11TFIV20 both map to the same 56-pin land pattern.

Frequently asked questions

What are the alternatives or equivalents for the S29GL128P11TFI020?

The closest functional equivalent is the S29GL128S10TFIV13 from the GL-S series — same 128 Mbit density, same parallel interface, but with a 100 ns access time and 60 ns write cycle. For higher density without a footprint change, the S29GL512T11TFIV20 (512 Mbit) shares the 56-TSOP package.
