DS3514
or exceeds +150°C. In this state, the VCOM buffer is
disabled (output goes high impedance) until the junc-
tion temperature falls below +150°C.
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
I2C bus. Connecting A0 to GND results in a 0 in the
corresponding bit position in the slave address.
Conversely, connecting A0 to VCC results in a 1 in the
corresponding bit position. For example, the DS3514’s
slave address byte is C0h when A0 is grounded. I2C
communication is described in detail in the
I2C Serial
Interface Description section.

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
I2C
Serial Interface Description section.
