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.
