Product Overview
The Q427242110002 RTC-72421 is a Real Time Clock IC Module that can be connected directly to a microprocessors bus. Its built-in crystal unit enables highly accurate time-keeping with no physical access required for adjustment and since there is no need to connect external components and mounting. In addition to its time and calendar functions, this enables the use of 30-seconds correction and fixed-period interrupts functions.
- Built-in crystal unit removes need for adjustment
- Microprocessor bus compatible
- Use of C-MOS IC enables low current consumption
- Compatibility with Intel CPU bus
- Address latch enable (ALE) pin compatible with multiplex bus CPUs
- Fixed-period interrupts function
- Stop, start and reset functions
