Memory
Signals in the OM6359 enable two memories. They use two volt supply voltage, VDD3 in the PCF50601 & VDD_1.9V
with a LDO. This system uses Intel's memory, RD38F3050LOZTQ0. It is consisted of 128M bits flash NOR memory and
64M bits SRAM. It has 16 bit data line, HD[0~15] which is connected to OM6359. It has 26 bit address lines,
HA[1~26]. NCSFLASH & NCSRAM signals are chip select. Writing process, HWR_N is low and it enables writing
process to flash memory and SRAM. During reading process, HRD_N is low and it enables reading process to flash
memory and SRAM. Reading or writing procedure is processed after HWR_N or HRD_N is enabled.
