General Description

VCC RST DQ CLK GND VBAT NC - +5V - Reset - Data Input/Output - Clock - Ground - Battery (+) - No Connection 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.

Nonvolatility can be achieved by connecting a battery of 2V to 4V at the battery input VBAT.

Key Features

  • 1024 Bits of Read/Write Memory Low Data Retention Current for Battery Backup.
