description (continued)
In addition to the power-on-reset and undervoltage-supervisor function, the TLC77xx adds power-down control
support for static RAM. When CONTROL is tied to GND, RESET will act as active high. The voltage monitor
contains additional logic intended for control of static memories with battery backup during power failure. By
driving the chip select (CS) of the memory circuit with the RESET output of the TLC77xx and with the CONTROL
driven by the memory bank select signal (CSH1) of the microprocessor (see Figure 10), the memory circuit is
automatically disabled during a power loss. (In this application the TLC77xx power has to be supplied by the
battery.)
The TLC77xxI is characterized for operation over a temperature range of –40

C to 85
