I am designing a microcontroller based delay circuit to implement delays of 2,hours hours, 1hour1 hour, 45 minutes, and 30 minutes Micro Controller based delay circuit. The circuit will automatically turn on off the Relay as Programmeda relay after this time period has elapsed.

I am stuck with somea narrow varietiesselection of micro controllersmicrocontrollers available locally in market(89C51, 89C52, 89S51, 89S52, 89C2051, PIC 16C71 and PIC 16F84).:

Maximum attainable delay with PIC16F84 Micro controller

I am designing a 2,hours, 1hour, 45 minutes, and 30 minutes Micro Controller based delay circuit. The circuit will automatically turn on off the Relay as Programmed.

I am stuck with thesome narrow varieties of micro controllers available locally in market(89C51, 89C52, 89S51, 89S52, 89C2051, PIC 16C71 and PIC 16F84). I think PIC is my only choice as the 89 series Micro Controllers can't be programmed for such long delay. I have checked the datasheet of PIC 16F84 and PIC 16C71these micro controllers but there is no information about the maximum delay itthey can produce.
