GENERAL DESCRIPTION

The Macronixs Solid State Disk controller is fully integrated flash memory controller that provides all the control logic for a PC Card ATA flash memory. The MX9691A combines 1KB dual-port buffer and buffer manager, integrated MX93011 DSP core , and a complete host interface for both the PC Card ATA and ATA standard.

FEATURES

Host Interface

• Fully compatible with PCMCIA Release 2.1, and PC Card ATA Release 1.02 specification.

• Compatible with all PC Card Services and Socket Service.

• Fast ATA host-to-buffer burst transfer rates up to 20MB/sec. which support PIO mode 4(16.6MB/sec) and DMA mode 3(16.6MB/sec).

• Automatic sensing of PCMCIA or ATA host interface.

• Integrated PCMCIA attribute memory of 256 bytes (CIS).

- CIS and Buffer RAM use same SRAM area to simplify internal bus design

• PCMCIA card configuration register support.

• Polarity control for host reset signal.

• PCMCIA twin card support.

• PCMCIA based ATA address decode support.

• Emulate the IBM task file for PC/AT.

• Separate status for Bus reset and Host program reset.

• Separate Host and Disk interrupt pins.

Flash Memory Interface

• Support all the control signals to execute read/write/erase operation for flash memory.

• Upto 32MB(unformatted) capacity for 16 pcs. 16Mbit flash memory or 64MB(unformatted) capacity for 16 pcs. 32Mbit flash memory.

• Flash Memory Power Down or write protect control support. - Dont power down the flash memory chip which used to store firmware

• Flash Memory Ready/Busy status detect.

• Inverted data bus control to reduce program operation in DOS FAT and ECC code field.

• Optional store firmware in flash memory array w/o externalROM. - Shadow ROM control to allow code fetch during data program or erase

• Media speed is upto 8MB/sec, sustain read data rate and 125KB/sec write data rate.

Buffer RAM control

• Dual port circular Buffer RAM control

• 1KB data Buffer RAM.

• Automatically correct error data in Buffer RAM.

- Single word error correct and double word detect.

• Provide logic to speed up Buffer RAM access.

• Support 8 bit as well as 16 bit transfer on host bus.

DSP core

• High performance MX93011 DSP (21Mips) core.

• 4KB Internal RAM(direct access).

• 2KB Internal expansion RAM(indirect access) for store data or shadow ROM space.

• ICE debugging mode supported to ease system verification.

• Lower power and automatic power saving operation

Technology
