Description:

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 functionality. (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.
