Memory selection for firmware storage
The S29GL064S80FHIV20 is a 64 Mbit parallel NOR flash from Infineon's GL-S family, organized as 8M x 8 or 4M x 16 via the parallel interface. The 80 ns access time sets the read latency ceiling for code execution in place — the CPU waits on the flash for each fetch, so this part suits systems where the bus clock stays below ~12.5 MHz for zero-wait-state operation. The 60 ns write cycle time per word or page means firmware updates in the field complete in milliseconds per sector, not seconds.
FBGA package — rework and board integration
The 64-FBGA supplier package code maps to a standard JEDEC footprint — no custom land pattern needed.
Lifecycle and compliance
RoHS3 compliant, so no exemption expiry to track for EU shipments.
