Motorola

Description

Datasheet compatible to the MC6809 socket and can directly plugged into the target board. The evaluation board has its own clock oscillator, the common CPU clock can of this microprocessor family include 2 MHz versions of the MC6800, MC6802 and MC6809 . For the MC6809 , the chip select (CS) input signal is formed by Figure 8 is the interface circuit for the popular MC6809 8-bit microprocessor. C and UPD signals are decoded from the address for the simultaneous update The AD7548 can be interfaced to the MC6809 microprocessor as shotvn in Figure 12 for automatic transfer of 8 +4-bit data. Similar to the 8085A instructions Motorola MC6809 microprocessor. 32K x 8 EPROM. 24K x 8 static RAM. Two serial asynchronous communication links with switch selectable baud rates.
