GENERAL DESCRIPTION

The Z86C61/62/96 microcontroller is a member of the Z8 single-chip microcontroller family with 16 Kbytes of ROM and 256 bytes of RAM. The Z86C96 is ROMless. The Z86C61 is offered in 40-pin DIP and 44-pin PLCC style packages, however, the ROMless pin option is available on the 44-pin version only. The Z86C62/96 is offered in 64-pin DIP and 68-pin PLCC style packages. A ROMless pin option enables these MCUs to address both external memory and preprogrammed ROM, making them well suited for high-volume applications or where code flexibil ity is required.
