MX9691L

The Macronix's Solid State Disk controller MX9691L is a wide-range supply voltage(3.3Volt~5Volt) and fully in- tegrated flash memory controller that provides all the control logic for PCMCIA/True IDE host and flash memory. The MX9691L combines 1KB dual-port buffer and buffer manager, integrated MX93011 DSP core, and a complete host interface for both the PC Card ATA and True IDE standard.

The MX9691L provides flexible disk capacity configu- ration and supports all the control signals to execute read/write/erase operation for linear type or series type flash memory chip. It is typically configured with up to 32MB(unformatted) capacity for 16 pcs. 16Mbit linear flash memory or 1GB(unformatted) capacity for 32 pcs. 256Mbit series type flash memory while capacity extention mode is enabled for series type flash memory used. The MX9691L also provides flexible architecture to implement defect management and wear-leveling by firmware for series type or linear type flash memory. n linear mode, the linear type 16 Mbit flash memory is supported, such as MXIC's MX29F1610 etc. In flash memory interface there are two banks of flash memory to be provided. Each bank support 8 pcs. flash memory when inear type flash memory is used. In series mode, the se- ries type 16MBit/32Mbit/64Mbit/256Mbit flash memory is supported, such as Toshiba's TC5816FT/TR or TC58V32FT, Samsung's KM29N16000T/R or  M29N32000TS/RS etc. Each bank support or 16 pcs. lash memory when series type flash memory is used.

The MX9691L is fully compliant with the PC Card ATA specification. It includes 256 bytes of integrated attribute memory(for the required Card Information Structure) and our Card Configuration registers. The PCMCIA device driver can access the MX9691L's ATA command block hrough four different modes by writing the different modes by writing the configuration index of the attribute memory configuration option register.
