The S25FL064LABBHV023 is a 64 Mbit NOR flash memory from Cypress's FL-L series, organized as 8M x 8 bits. It uses the SPI - Quad I/O and QPI interface, which at 108 MHz clock frequency gives a fast read throughput for code shadowing or execute-in-place (XIP) applications. The memory is non-volatile, so it holds firmware and configuration data across power cycles. The supplier device package is 24-BGA (8x6).
108 MHz clock — timing margin for the SPI bus
The Quad SPI interface operates at 108 MHz.
