GENERAL DESCRIPTION  
™
The enhanced Z80180/Z8S180/Z8L180 significantly im-  
Not only does the Z80180/Z8S180/Z8L180 consume less  
power during normal operations than the previous model,  
it has also been designed with three modes intended to fur-  
proves on the previous Z80180 models while still providing  
full backward compatibility with existing Zilog Z80 devices.  
The Z80180/Z8S180/Z8L180 now offers faster execution  
speeds, power saving modes, and EMI noise reduction.  
ther reduce the power consumption. Zilog reduced I pow-  
cc  
er consumption during STANDBY Mode to a minimum of  
10 µA by stopping the external oscillators and internal  
clock. The SLEEP mode reduces power by placing the  
CPU into a “stopped” state, thereby consuming less cur-  
rent while the on-chip I/O device is still operating. The  
SYSTEM STOP mode places both the CPU and the on-  
chip peripherals into a “stopped” mode, thereby reducing  
power consumption even further.  
This enhanced Z180 design also incorporates additional  
feature enhancements to the ASCIs, DMAs, and I  
cc  
STANDBY Mode power consumption. With the addition of  
“ESCC-like” Baud Rate Generators (BRGs), the two ASCIs  
now have the flexibility and capability to transfer data asyn-  
chronously at rates of up to 512 Kbps. In addition, the ASCI  
receiver has added a 4-byte First In First Out (FIFO) which  
can be used to buffer incoming data to reduce the inci-  
dence of overrun errors. The DMAs have been modified to  
allow for a “chain-linking” of the two DMA channels when  
set to take their DMA requests from the same peripherals  
device. This feature allows for non-stop DMA operation be-  
tween the two DMA channels, reducing the amount of CPU  
intervention (Figure 1).  
A new clock doubler feature has been implemented in the  
Z80180/Z8S180/Z8L180 device that allows the program-  
mer to double the internal clock from that of the external  
clock. This provides a systems cost savings by allowing  
the use of lower cost, lower frequency crystals instead of  
the higher cost, and higher speed oscillators.  
The Enhanced Z180 is housed in 80-pin QFP, 68-pin  
PLCC, and 64-pin DIP packages.
