Overview

Z86Cl1 CMOS Z8® 4K ROM MCU FEATURES m Complete microcomputer, 4K bytes of ROM, 256 bytes of RAM, 32 I/O lines, and up to 6DK bytes addressable external space each for program and data memory.
II! 256-byte register file, including 236 general-purpose registers, four I/O port registers, and 16 status and control registers.
(liJ Vectored, priority interrupts for 110, counter/timers, and UART.
I:'!l Full-duplex UART and two programmable 8-bit counter/ timers, each with a 6-bit programmable prescaler.
June 1987 El Register Pointer so that short, fast instructions can access any of 16 working-register groups in 1.
5 !ls.
I!!) On-chip oscillator which accepts crystal or external clock drive.
C'.
I Standby modes-Halt and Stop o Single + 5V power supply-all pins TIL-compatible.
