This document introduces a PCMCIA interface product that is fully compatible with PCMCIA Release 2.1 and PC Card ATA Release 1.02 specifications. It supports fast ATA host-to-buffer burst transfer rates up to 20MB/sec, with automatic sensing of PCMCIA or ATA host interface. The product features integrated PCMCIA attribute memory, PCMCIA card configuration register support, polarity control for host reset signal, PCMCIA twin card support, PCMCIA based ATA address decode support, and emulation of the IBM task file for PC/AT. It also provides a flash memory interface with support for read/write/erase operations, up to 32MB or 64MB capacity, flash memory power down or write protect control, flash memory ready/busy status detection, inverted data bus control, and optional storage of firmware in flash memory array with shadow ROM control.
The Macronix MX9691 is an integrated flash memory controller designed for use as a PC Card ATA device. It combines a host interface supporting both PCMCIA Release 2.1 and PC Card ATA Release 1.02 specifications, along with a Flash Memory Interface capable of supporting up to 32MB or 64MB of unformatted capacity depending on the flash memory configuration.
The controller features an integrated MX93011 DSP core for high performance data processing and includes a dual-port circular Buffer RAM for error correction and speed optimization. It operates using five-volt-only power supply in a 128-pin TQFP package fabricated with 0.6um Low-power, High-speed CMOS technology.
