概觀
The IS66/67WVQ4M4DALL/BLL are integrated memory device containing 16Mb Pseudo Static Random Access
Memory, using a self-refresh DRAM array organized as 2M words by 8 bits.
The device supports Quad DDR interface, which is compatible with JEDEC standard x4 xSPI Flash.
The device supports Very Low Signal Count (7 signal pins; SCLK, CS#, DQSM, and 4 SIOs), Hidden Refresh
Operation, and Automotive temperature (A3, -40°C to +125°C) operation.
Due to DDR operation, minimum transferred data size is a byte (8 bits) through 4 SIO pins.
