Other Power Saving Options
The PSD6XXE1 offers other reduced power saving options that are independent of the
Power Down or Sleep Mode. Except for the SRAM Standby and CSI input features, they are
enabled by setting bits in the PMMR 0 register.
J
CMiser Bit
The CMiser bit resides in PMMR0. This bit controls the AC power consumption and
access time of the EPROM and SRAM. When CMiser is set and when in 8 bit data bus
mode, the PSD6XXE1 will consume the lowest level of AC power. However, the access
time will be slower (see CMiser adder in timing parameters). When CMiser bit is off, the
AC power is higher and the PSD6XXE1 will return to standard access time.
J
SRAM Standby Mode
The SRAM has a dedicated Vstby pin (PC2) that can be connected to a battery.
When V
CC
becomes lower than Vstby then the PSD6XXE1 will automatically connect
the Vstby as a power source to the SRAM. The SRAM Standby Current (Istby) is
typically 0.5μA. SRAM data retention voltage is 2V minimum.
J
The CSI Input
Pin PD2 of Port D can be configured in PSDsoft as the CSI input . When low, the signal
selects and enables the internal EPROM and SRAM for read or write operations of the
PSD6XXE1. A high on the CSI pin will disable the EPROM and SRAM and reduce the
PSD power consumption. However, the PLD remains operational when CSI is high.
J
Input Clock
The PSD6XXE1 provides the option to turn off the CLKIN input to the PLD to save
AC power consumption. The CLKIN is an input to the PLD AND array and the Output
Micro
Cells. During power down or if any of the CLKIN input is not being used as part
of the PLD logic equation, the clock should be disabled to save AC power.
The CLKIN will be disconnected from the PLD AND array or the Micro
Cells by
setting bit 4 or 5 to “1” in the PMMR0.
