AT43101

Features Supports PCMCIA PC Card Standard - Release 2.1 Directly connects to PCMCIA Connector No Additional Circuits Required 256 x 8 Internal Parallel E2PROM for CIS Endurance: 10,000 Write Cycles Data Retention: 10 Years Internally Controlled Write Algorithm Operates over VCC = 4.5 to 5.5 Volts 64 Pin TQFP, Max. Height = 1.2 mm Mounted Usage is Two Devices Per Card Dual Mode Device with Mode Select Pin Supports Up to 64 Mbytes of: Flash E2PROM SRAM ROM OTP 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 interface 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.
