The Z86193 is a CMOS ROMless Z8 microcontroller enhanced with a hardwired 16-bit x 16-bit multiplier, 32-bit/16-bit divider, three 16-bit counter/timers, search and merge instructions, Evaluation mode and a Bus Request mode. The device is code compatible with other Z8 family devices, yet it offers more powerful mathematical capabilities, data searching capabilities, and bit manipulation. The Z86193 is offered in a 64-pin VQFP package. The Z86193 provides up to 16 output address lines permitting an address space of up to 64 Kbytes each of Program or Data memory. Eight address outputs are provided by a de-multiplexed 8-bit Address Bus (A7-A0) or by a multiplexed 8-bit Address/Data Bus (AD7-AD0). The remaining eight address lines (A15-A8) can be provided by the software configuration of Port0 to output address. The Z86193 includes a bus which differs from other Z8 devices. The Z86193 provides bus control signals /RD (Read Strobe), /WR (Write Strobe), and ALE (Address Latch Enable). |
