Product Summary
The MC6809P is a high-performance 8-bit microprocessor which supports modern programming techniques such a s position independence, re-entrancy, and modular programming. The MC6809P has major architectural improvements which include additional register,s instructions, and addressing modes. The MC6809P has the most complete set of addressing modes available on any 8-bit microprocessor. The MC6809P has hardware and software features which make it an ideal processor for higher level language execution or standard controller applications.
Parametrics
MC6809P absolute maximum ratings: (1)supply voltage, VCC: -0.3 to 7.0V; (2)input voltage, VIN: -0.36 to 7.0V; (3)operating temperature range, TA: -40 to 85℃; (4)storage temperature range, Tstg: -55 to 150℃.
Features
MC6809P features: (1)on-chip oscillator; (2)DMA BREQ allows DMA operation on memory refresh; (3)fast interrupt request input stacks only condition code register and program counter; (4)MRDY input extends data access times for use with slow memory; (5)interrupt acknowledge output allows vectoring by devices; (6)sync acknowledge output allows for synchronization to external event; (7)single bus-cycle RESET; (8)single 5-Volt supply operation; (9)NMI inhibited after RESET until after first load of stack pointer; (10)early address valid allows use with slower memories; (11)early write data for dynamic memories.
