Description  
The AT43101 is a low power, high integration PCMCIA interface chip set for memory  
cards. It provides a complete PCMCIA PC Card Standard Release 2.1 compliant inter-  
face with no other support devices. Two AT43101’s are used on each memory card.  
A mode select pin configures the device for operation as a low order address and data  
buffer when low and as the high order address buffer/decoder when high. The two  
devices together form a complete address and data buffer, address decoder, memory  
device selection logic, read and write control logic and a Card Information Structure  
(CIS). Eight chip enable outputs are provided, supporting 16 memory devices. The  
device is pinned out for direct connection to the PCMCIA connector without PC trace  
cross-overs. Its 1.0 mm thick body allows population of both sides of a Type 1  
PCMCIA card.
