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, active-low RST, and DQ. Nonvolatility can be achieved by connecting a battery of 2V to 4V at the battery input VBAT. A load of 0.5µA should be used to size the external battery for the required data retention time. If nonvolatility is not required the VBAT pin should be grounded.

Key Features		Applications/Uses
1024 Bits of Read/Write Memory Low Data Retention Current for Battery Backup Applications Four Million Bits/Second Data Rate Single-Byte or Multiple-Byte Data Transfer Capability No Restrictions on the Number of Write Cycles Low-Power CMOS Circuitry		Automatic System Setup Calibrators Computer Identification Secure Personnel Areas Software Authorization Systems Access Control Traveling Work Record
