• Manufacturer Part Number: sak-xc2387a-56fxxl
• Description: 16/32-bit Single-chip Microcontroller With 32-bit Performance
• Manufacturer: Infineon Technologies Corporation

Access to the XC238xA Flash modules is controlled by the IMB. Built-in prefetch
mechanisms optimize the performance for sequential access.
Flash access waitstates only affect non-sequential access. Due to prefetch
mechanisms, the performance for sequential access (depending on the software
structure) is only partially influenced by waitstates.
