Offered in 40-pin DIP or 44-pin PLCC package styles, these devices are pin-compatible EPROM versions of the Z86C61/ 63. The ROMless pin option is available on the 44-pin versions only. With 4 Kbytes of ROM and 236 bytes of general-purpose RAM, the Z86E61/E63 offers fast execution, efficient use of memory, sophisticated interrupts, input/output bit manipulation capabilities, and easy hardware/software system expansion. For applications demanding powerful I/O capabilities, the Z86E61/E63 offers 32 pins dedicated to input and output. These lines are grouped into four ports. Each port consists of eight lines, and is configurable under software control to provide timing, status signals, serial or parallel I/O with or without handshake, and an address/data bus for interfacing external memory. The Z86E61/E63 can address both external memory and preprogrammed ROM, making it well suited for highvolume applications or where code flexibility is required. 1 P R E L I M I N A R Y WITH 16K/32K Z86E61/E63 Z8® MCU EPROM GENERAL DESCRIPTION (Continued) There are three basic address spaces available to support this configuration: Program Memory, Data Memory, and 236 general-purpose registers. To unburden the system from coping with real-time tasks such as counting/timing and serial data communication, the Z86E61/E63 offers two on-chip counter/timers with a large number of user selectable modes (Figure 1). Notes: All Signals with a preceding front slash, "/", are active Low, e.g., B//W (WORD is active Low); /B/W (BYTE is active Low, only).
