REAL TIME CLOCK MODULE RTC72421 The RTC72421 module is a Real Time Clock designed for use with microprocessors. The built-in 32.768 kHz standard clock quartz oscillator eliminates the need for regulation. The RTC72421 uses little or no external hardware (depending on application), and greatly enhances ease of incorporation into circuit designs.
