Hot-selling and scarce UM6502 8-Bit Microprocessors IC DIP40 spot stock

Product Descriptions

The UM6502/UM6507/UM6512 microprocessors are totally software compatible with one another. These products provide a selection of addressable memory range, interrupt input options and on-chip clock oscillators and drivers. The UM6502/UM6507 on-chip clock versions are aimed at high performance, low cost applications where single phase inputs or crystals provide the time base. The UM6512 external clock version is geared for the multiprocessor system applications where maximum timing control is mandatory. These products are bus compatible with the MC6800 product offering.
