three modes intended to further reduce power consumption.  
Power consumption during 56#0&$; Mode is reduced to  
10 µA by stopping the external oscillators and internal  
clock. The 5.''2 mode reduces power by placing the CPU  
into a stopped state, consuming less current while the on-  
chip I/O devices still operate. The 5;56'/ꢅ5612 mode  
places both the CPU and the on-chip peripherals into a  
stopped mode, reducing power consumption even further.  
The enhanced Z8S180/Z8L180 significantly improves on  
previous Z80180 models, while still providing full back-  
ward compatibility with existing ZiLOG Z80 devices. The  
Z8S180/Z8L180 now offers faster execution speeds, pow-  
er-saving modes, and EMI noise reduction.  
™
This enhanced Z180 design also incorporates additional  
feature enhancements to the ASCIs, DMAs, and 56#0&$;  
mode power consumption. With the addition of ESCC-like  
BaudRateGenerators(BRGs),thetwoASCIsoffertheflex-  
ibility and capability to transfer data asynchronously atrates  
of up to 512 Kbps. In addition, the ASCI receiver features  
a 4-byte first in/first out (FIFO) buffer which reduces the  
likelihoodofoverrunerrors.TheDMAshavebeenmodified  
to allow for chain-linking of the two DMA channels when  
set to take their DMA requests from the same peripherals  
device. This feature allows for nonstop DMA operation be-  
tween the two DMA channels.  
A new clock-doubler feature in the Z8S180/Z8L180 allows  
the internal clock speed to be twice the external clock speed.  
As a result, system cost is reduced by allowing the use of  
lower-cost, lower-frequency crystals.  
The Enhanced Z180 is housed in 80-pin QFP, 68-pin PLCC,  
and 64-pin DIP packages.
