128 Mbit parallel NOR Flash — what the 110 ns access time means for your bus
The Infineon S29GL128P11FAIV20 is a 128 Mbit parallel NOR Flash from the GL-P series, organized as 16M x 8 bits. It uses a standard parallel interface with a 110 ns access time, which sets the read-cycle window the host controller must accommodate. The supply range spans 1.65 V to 3.6 V.
Package and temperature grade — assembly and environment check
Housed in a 64-FBGA (13x11) package, surface-mount only. The BGA footprint saves board area but demands a controlled reflow profile and post-solder X-ray inspection — factor that into your assembly yield budget. The operating temperature range is -40°C to 85°C (ambient), a standard industrial grade that covers most outdoor telecom, factory automation, and infrastructure equipment. No AEC-Q grade is listed, so this part is not qualified for automotive under-hood or chassis domains.
Lifecycle status — active, no LTB watch needed
The manufacturer lists this part as Active. For a BOM line, this means no supply discontinuity risk from obsolescence in the near term. The GL-P series sits alongside the newer GL-S and GL-T families, but the GL-P remains a current-production option.
RoHS note
This variant is marked RoHS non-compliant. If your assembly line requires RoHS or lead-free solder, verify the exemption or consider the RoHS-compliant suffix options in the GL-P family.
