Product Summary

Code Compatible with ZiLOG Z80Extended InstructionsTwo Chain-Linked DMA ChannelsLow Power-Down ModesOn-Chip Interrupt ControllersThree On-Chip Wait-State GeneratorsOn-Chip Oscillator/GeneratorExpanded MMU Addressing (Up to 1 MB)Clocked Serial I/O Port?The enhanced Z8S180/Z8L180significantly improves onprevious Z80180 models, while still providing full back-ward compatibility with existing ZiLOG Z80 devices. TheZ8S180/Z8L180 now offers faster execution speeds, pow-er-saving modes, and EMI noise reduction.?This enhanced Z180design also incorporates additionalfeature enhancements to the ASCIs, DMAs, andmode power consumption. With the addition of ESCC-likeBaud Rate Generators (BRGs), the two ASCIs offer the flex-ibility and capability to transfer data asynchronously at ratesof up to 512 Kbps. In addition, the ASCI receiver featuresa 4-byte first in/first out (FIFO) buffer which reduces thelikelihood of overrun errors. The DMAs have been modifiedto allow for chain-linking of the two DMA channels whenset to take their DMA requests from the same peripheralsdevice. This feature allows for nonstop DMA operation be-tween the two DMA channels
