Does anyone know of a real time clock chip that can interface directly
to an 8051. Everyone I've seen so far is to slow to interface at 16 MHz.
The 8051 can't be wait stated so there aren't many options. I really don't
want to latch the data and extend the WR & RD pulses with one shots.
Any advice would be greatly appreciated. Samples would be nice too.
