GENERAL DESCRIPTION
The Z86C27 and Z86C97 Digital Television Controller (DTC) introduce a new level of sophistication to single-chip architecture. The Z86C27/C97 are members of the Z8 single-chip microcontroller family with 8 Kbytes of ROM (Z86C27), ROMless (Z86C97) and 236 bytes of RAM. Both devices are housed in a 64-pin DIP package, and are CMOS compatible. Having the ROM/ROMless selectivity, the DTC offers both external memory and pre-programmed ROM which enables the Z8 microcontroller to be used in a high volume production application device embedded with a custom program (customer supplied program). The Z86C97 ROMless offers the use of external memory rather than a preprogrammed ROM. This enables the Z8 microcontroller to be used in prototyping, low volume applications or where code flexibility is required. Zilog’s DTC offers fast execution, efficient use of memory, sophisticated interrupts, input/output bit manipulation capabilities, and easy hardware/software system expansion along with low cost and low power consumption. The device provides an ideal performance and reliability solution for consumer and industrial television applications.
