Slave Address Byte and Address Pin

The slave address byte consists of a 7-bit slave

address plus a R/W bit (see Figure 5). The DS3514’s

slave address is determined by the state of the A0 pin.

This pin allows up to two devices to reside on the same

corresponding bit position in the slave address.

corresponding bit position. For example, the DS3514’s

communication is described in detail in the

Interface Description section.

Memory Organization

Memory Description

The list of registers/memory contained in the DS3514 is

shown in the

Memory Map section. Also shown for

each of the registers is the memory type, accessibility,

as well as the power-up default values for volatile loca-

tions and factory-programmed defaults for the non-

volatile locations. Additional information regarding

reading and writing the memory is located in the

Serial Interface Description section.
