Parallel NOR Flash for code shadowing and data storage
The Infineon S29GL064S70TFI060 is a 64 Mbit parallel NOR Flash memory from the GL-S series, organized as 4M x 16.
In a system with a 50 MHz to 66 MHz host bus, this timing provides enough margin for zero-wait-state reads when the memory controller's setup and hold windows are properly sized. For faster controllers or when the bus is shared with other peripherals, the 70 ns window still allows single-cycle access without external buffers in most cases. The write cycle time for word and page operations is 60 ns, meaning the device can accept back-to-back writes at that rate once the preceding program cycle completes. This keeps firmware update times predictable even for large blocks.
Industrial temperature range — where it goes
The full temperature range applies to both read and write operations, so no derating is needed for firmware updates in cold-start conditions.
Package and footprint — 48-TSOP
Housed in a 48-TFSOP (0.724", 18.40 mm width) package, also referred to as 48-TSOP, this is a standard surface-mount footprint for parallel NOR Flash. The 48-TSOP form factor is widely used across multiple densities in the GL-S family, so a board layout designed for this part can accommodate other densities (e.g., 128 Mbit) with the same pinout.
