Hi guys,
Is there another 8051 chip that can replace the DS5000T chip from Dallas ? I want to construct a Real-time controlled AC relays published in 'Reynolds' website (http://www.rentron.com/Project5.htm ) for my fish tank but upon checking the price of the DS5000T MCU, I was shocked. It is priced at about USD73.00 per piece in Singapore. Too much for me to swallow.
I was thinking, since the DS5000T is from the 8051 family, I am not sure whether are there any equivalents say, from ATMEL. Or, if any of you know of a similar project (the MCU must control at least 2 relays preferably, 4) but is using a different MCU. I've some stock (commonly use types though) on both PICs and AVRs. I've some DS1307 (Real-time clock from Dallas) too. There is another 8051 project from Reynolds using ATMEL AT89C2051 but it is actually an alarm clock. I think I can modifiy the circuit to control a relay but I do not know how to add codes to use another PIN for another relay.
Many thanks in advance.
Davis
