Product Summary

The enhanced Z8S18020FSG microprocessor significantly improves on previous Z80180 models, while still providing full backward compatibility with existing ZiLOG Z80 devices. The Z8S18020FSG now offers faster execution speeds, power-saving modes, and EMI noise reduction. This enhanced device design also incorporates additional feature enhancements to the ASCIs, DMAs, and standby mode power consumption. With the addition of ESCC-like Baud Rate Generators (BRGs), the two ASCIs of the Z8S18020FSG offer the flexibility and capability to transfer data asynchronously at rates of up to 512 Kbps. In addition, the ASCI receiver features a 4-byte first in/first out (FIFO) buffer which reduces the likelihood of overrun errors.
