DS1200集成电路（IC）的存储器规格书PDF中文资料

DESCRIPTION

The DS1200 serial RAM chip is a miniature read/write memory that can randomly access individual 8-bit strings (bytes) or sequentially access the entire 1024-bit contents (burst). Interface cost to a microprocessor is minimized by on-chip circuitry, which permits data transfers with only three signals: CLK, RST , and DQ.
