NS32FX211 Microprocessor Compatible Real Time Clock
General Description
The NS32FX211 is fabricated using low threshold CMOS
technology and is designed to operate in bus oriented mi-
croprocessor systems where a real time clock and calendar
function are required. The on-chip 32.768 kHz crystal con-
trolled oscillator will maintain timekeeping down to 2.2V to
allow low power standby battery operation.
