PRODUCTION DATA
Refer to the PDF data sheet for device specific package drawings
All volatile memory (RAM and ROM) on the F28P55x device is 0 Wait-state for both reads and writes, meaning the memory operates at the same speed as SYSCLK. Table 6-7 and Table 6-8 summarize the characteristics of the different RAM instances on the device.
