6808P CPU

MOTOROLA MC6808P DIP-40 8-BIT MPUS 8-BIT MCUS 8-BIT

The MC6802 is a monolithic 8-bit microprocessor that contains all the registers and accumulators of the present MC6800 plus an internal clock oscillator and driver on the same chip. In addition, the MC6802 has 128 bytes of on-board RAM located at hex addresses $0000 to $007F. The first 32 bytes of RAM, at hex addresses $0000 to $001F, may be retained in a low power mode by utilizing Vcc standby; thus, facilitating memory retention during a power-down situation. The MC6802 is completely software compatible with the MC6800 as well as the entire M6800 family of parts. Hence, the MC6802 is expand-able to 64K words. The MC6802NS is identical to the MC6802 without standby RAM feature. The MC6808 is identical to the MC6802 without on-board RAM.
