POWER-UP/POWER-DOWN CONSIDERATIONS
The DS1670 was designed to operate with a power supply of 3.3V. When 3.3V are applied within
nominal limits, the device becomes fully accessible after tRPU (250ms typical). Before tRPU elapses, all
inputs are disabled. When VCC drops below 2.88V (typical), the RST pin is driven low. When VCC drops
below the lower of 2.7V (typical) or the battery voltage, the device is switched over to the backup power
supply.
During power-up, when VCC returns to an in-tolerance condition, the RST pin is kept in the active state
for 250ms (typical) to allow the power supply and microprocessor to stabilize.
ADDRESS/COMMAND BYTE
The command byte for the DS1670 is shown in Figure 2. Each data transfer is initiated by a command
byte. Bits 0 through 6 specify the addresses of the registers to be accessed. The MSB (bit 7) is the
Read/Write bit. This bit specifies whether the accessed byte will be read or written. A read operation is
selected if bit 7 is a 0 and a write operation is selected if bit 7 is a 1. The address map for the DS1670 is
shown in Figure 3.
