MX9691A

SINGLE CHIP SOLID STATE DISK CONTROLLER

Macronix International 

MX9691A

GENERAL DESCRIPTION

The Macronix's Solid State Disk controller is fully inte-

grated flash memory controller that provides all the con-

trol logic for a PC Card ATA flash memory. The MX9691A

combines 1KB dual-port buffer and buffer manager, inte-

grated MX93011 DSP core , and a complete host inter-

face for both the PC Card ATA and ATA standard.

The MX9691A is typically configured with up to

32MB(unformatted) capacity for 16 pcs. 16Mbit flash

memory or 64MB(unformatted) capacity for 16 pcs.

32Mbit flash memory. The MX9691A supports all the

control signals to execute read/write/erase operation for

flash memory chip.

The MX9691A is fully compliant with the PC Card ATA

specification. It includes 256 bytes of integrated attribute

memory(for the required Card Information Structure) and

four Card Configuration registers. The PCMCIA device

driver can access the MX9691A ATA command block

through four different modes by writing the different modes

by writing the configuration index of the attribute memory

configuration option register.

Description

Host address line 10-0.

These pins include internal pull-up resistors.

Host data line 15-0.

These pins include internal bus holder circuit that keep previous state

when tri-state.

Host memory read/write/mode select : Both pins include internal pull-

up resistors that is default in PCMCIA mode.

Host I/O access.

Both pins include internal pull-up resistors.

The host reset signal, when active, initializes the control/status

registers and stops any command in process.In PCMCIA mode, the

signal is active high. In ATA extension mode, this signal is active low.

This signal include internal pull-down resistor.

WAIT or INPUT CHANNEL READY : In both PCMCIA and ATA

extension modes, this signal holds host transfers until the controller is

ready to respond.

READY/BUSY or HOST INTERRUPT : In PCMCIA mode, this signal

has two functions. In PCMCIA common memory mode, this signal is

ready/busy. It is asserted busy by the reset logic, and can be deasserted

by the local uC. In PCMCIA I/O mode, this signal is IREQ#. In ATA

extension mode, this active high signal is HOSTINT, which, when

enable, send an interrupt to the host.
