**82C601/2       Buffer Devices                                 <Nov94
***Info:
OPTi’s 82C601 and  82C602 buffer devices are packaged  in 100-pin PFPs
(Plastic Flat Pack) and are designed to replace approximately nine TTL
components normally found  on PC/AT motherboards, offering significant
cost savings and a substantially simplified PCB layout.

Pin-compatible  with each  other, the  82C602 is  an upgrade  from the
82C601 that adds a real-time  clock (RTC) and power management functi-
onality.   (Later versions  of the  buffer  chip will  also include  a
keyboard controller.)

The 82C601 and 82C602 are closely coupled with OPTi's 82C801/802/802G,
82C499,  and 82C495SLC/XLC  chipsets to  allow higher  integration and
lower cost.
