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鈥檚 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.
