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-

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

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.
