DS1315 Phantom Time Chip

Nonvolatile Controller Operation

The operation of the nonvolatile controller circuits within the Time Chip is determined by the level of the

ROM/ RAM select pin. When ROM/ RAM is connected to ground, the controller is set in the RAM mode

and performs the circuit functions required to make CMOS RAM and the timekeeping function

nonvolatile. A switch is provided to direct power from the battery inputs or VCCI to VCCO with a

maximum voltage drop of 0.3 volts. The VCCO output pin is used to supply uninterrupted power to CMOS

SRAM. The DS1315 also performs redundant battery control for high reliability. On power-fail, the

battery with the highest voltage is automatically switched to VCCO. If only one battery is used in the

system, the unused battery input should be connected to ground.

The DS1315 safeguards the Time Chip and RAM data by power-fail detection and write protection.

Power-fail detection occurs when VCCI falls below VPF which is set by an internal bandgap reference. The

DS1315 constantly monitors the VCCI supply pin. When VCCI is less than VPF, power-fail circuitry forces

the chip enable output ( CEO ) to VCCI or VBAT-0.2 volts for external RAM write protection. During

nominal supply conditions, CEO will track CEI with a propagation delay. Internally, the DS1315 aborts

any data transfer in progress without changing any of the Time Chip registers and prevents future access

until VCCI exceeds VPF. A typical RAM/Time Chip interface is illustrated in Figure 3.

When the ROM/ RAM pin is connected to VCCO, the controller is set in the ROM mode. Since ROM is a

read-only device that retains data in the absence of power, battery backup and write protection is not

required. As a result, the chip enable logic will force CEO low when power fails. However, the Time

Chip does retain the same internal nonvolatility and write protection as described in the RAM mode. A

typical ROM/Time Chip interface is illustrated in Figure 4.
