1 Gbit parallel NOR Flash for code storage and execute-in-place
The Infineon S29GL01GT11TFIV10 is a 1 Gbit parallel NOR Flash memory from the GL-T series, organized as 128M x 8 bits. This device is typically used for firmware storage, boot code, and execute-in-place (XIP) applications in networking equipment, industrial controllers, and telecom infrastructure where deterministic read latency and high reliability are required.
The 110 ns access time is the random read latency from address assertion to valid data on the bus. The write cycle time for word and page operations is 60 ns.
Supply voltage flexibility and interface
The parallel interface uses address and data buses that require 28 address lines and 8 data lines (for the x8 organization), plus control signals (CE#, OE#, WE#). This pin count is the reason for the 56-pin TSOP package. The wide supply tolerance also simplifies power sequencing — the part can track a ramping supply without brown-out issues, as long as the ramp rate stays within the datasheet limits.
Package and footprint — 56-TSOP reflow considerations
The 56-TSOP package (0.724" body width, 18.40 mm) is a standard thin small-outline package with gull-wing leads on 0.5 mm pitch. It is compatible with conventional reflow soldering profiles (MSL 3 typical for this class). The surface-mount footprint is well established, and the package does not have an exposed thermal pad, so thermal dissipation relies on the leads and board copper. For high-temperature environments (approaching 85°C ambient), ensure adequate airflow or derate the operating temperature if the part is in a confined enclosure.
