Z8801
Overview
The Zilog SuperS single-chip MCU can be used for development and production. It can be used as I/O- or memory-intensive computers, or configured to address external memory while still supporting many I/O lines.
- Improved Z8t!) instruction set includes multiply and divide instructions, Boolean and BCD operations.
- Additional instructions support threaded-code languages, such as "Forth."
- 325 byte registers, including 272 general:purpose registers, and 53 mode and control registers.
- Addressing of up to 12SK bytes of memory.
- Two register pOinters allow use of short and fast instructions to access register groups within 600 nsec.
- Direct Memory Access con~roller (DMA).
- Two 16-bit counterItimers.
- Up to 32 bit-programmable and Sbyte-programmable 110 lines, with 2 handshake channels. .
- Interrupt structure supports: o 27 interrupt sources o 16 interrupt vectors (2 reserved for future versions) o Sinterrupt levels . o Servicing in 600 nsec. (1 levelonly)
- Full-duplex UARTwith special features.
