UESTIONS AND. A. NSWERS AN971800100. INSTRUCTIONS (Continued) For DAA (Decimal adjust), if you execute this instruction after DEC instruction (especially DEC instruction on 00h, then execute DAA), Z180 results in F9H while Z80 results in 99H. It is because the Z80 CPU refers “Inter- nal Carry flag” while the Z180 doesn’t.
The Z180 is ZiLOG's second generation Z80 based processor family. Building on its world famous Z80, ZiLOG's Z180 offers several feature and improvement that have made it an attractive platform for those who require higher CPU performance as well as peripheral integration.
The Z180 CPU project. The Z180 CPU is an 8 bit processor which has been built upon the Z80 CPU. The Z180 is compatible with the Z80 command set, but it is bringing more instructions and functionality, extended registers, and it includes a DMA, CTC, and SIO. It has also an extended memory addressing range to 1Mb (20 address lines).
Apr 14, 2023 · Z180. The Z80180 is an 8-bit MPU which provides the benefits of reduced system costs and also provides full backward compatibility with existing Zilog Z80 devices. Reduced system costs are obtained by incorporating several key system functions on-chip with the CPU.
64-Pin DIP. 80-Pin QFP. )'0'4#. &'5%4+26+10. The enhanced Z8S180/Z8L180TM significantly improves on previous Z80180 models, while still providing full back-ward compatibility with existing ZiLOG Z80 devices. The Z8S180/Z8L180 now offers faster execution speeds, pow-er-saving modes, and EMI noise reduction.

The Z180 CPU kit ("Black Adder") This project started with updating the Z180 CPU module (#25), but become a much larger project. I designed the first Z180 module (#28) in late spring 2018, and I made also linear memory module (#68) at the same time as a part of a 80pin bus project. The linear memory module was not supported by any means so it ...
