Description
SDRAM Chip Select: Active low chip select pins for SDRAM. The KS8695X supports
up to two SDRAM banks. One SDCSN output is provided for each bank.
SDRAM Row Address Strobe: Active low. The row address strobe pin for SDRAM.
SDRAM Column Address Strobe: Active low. The column address strobe pin for
SDRAM.
SDRAM Write Enable: Active low. The write enable signal for SDRAM.
SDRAM Data Input/Output Mask: Data input/output mask signals for SDRAM. The
SDQM is sampled high and is an output mask signal for write accesses and an
output enable signal for read accesses. Input data are masked during a write cycle.
The SDQM0/1/2/3 correspond to XDATA[7:0], XDATA[15:8], XDATA[23:16] and
XDATA[31:24], respectively.
External I/O Device Chip Select: Active low. Three external I/O banks are provided
for external memory mapped I/O operations. Each I/O bank stores up to 16KB.
The ECSNx signals indicate which of the three I/O banks is selected.
External DATA Bus. 32-bit bidirectional data bus for data transfer. KS8695X also
supports 8- and 16-bit data bus widths.
