Z8800 Datasheet | Zilog

Zilog January 1988 Product Specification Super8™ MCU ROMless, ROM, and Prototyping Device with EPROM Interlace Z8800,Z8801,Z8820,Z8822 Features - 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 p Ointers allow use of short and fast instructions to access register groups within 600 nsec. - Direct Memory Access con~roller (DMA). - Two 16-bit counter Itimers. - 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 . - On-chip oscillator. - 20 MHz clock. - SK byte ROM for ZSS20 GENERAL DESCRIPTION The Zilog Super S single-chip MCU can be used for development and production. It can be used as I/O- or memory-intensive puters, or configured to address external memory while still supporting many I/O lines. Ne Vee ROMIe. . "" ,."
