The MC68B02P features an 8-bit data bus and a 16-bit address bus, allowing it to address up to 64KB of memory. It operates at a clock frequency of up to 2 MHz. The processor includes several internal registers, including an accumulator, index register, and stack pointer. It also features interrupt handling capabilities, allowing it to respond to external events in real-time. The MC68B02P is typically packaged in a DIP (Dual In-line Package). It requires a single 5V power supply for operation. The 'B' in the name denotes that this particular version is capable of running at the faster 2 MHz clock speed (as opposed to the original '6802').
