• Manufacturer Part Number: mcf5307cft90b
• Description: Mcf5307 Coldfire Integrated Microprocessor User
• Manufacturer: Freescale Semiconductor, Inc

Asynchronous Operation
Note that in Table 11-8, MCF5307 pin A19 is not connected because DRAM address bit 18
is already provided on MCF5307 pin A18; thus, the next MCF5307 pin used should be A20.
