Hello Joe!
and thanx for responding. Its an 5V system, with on board SMPS, mains powered. Temp. spec is max. 70 C. No vibration. All 4 devices µc - eeprom - DAC and RTC are on board. The µc is a Dallas DS89C450 with no on chip i2c hardware so it will be a low speed, bit-banged i2c solution. The application is a control application; it will read input pushbuttons, switch relays on or off, and provide slowly varying DC (0-10V) outputs. In some applications there will be serial comms. betwen two devices. I know the Philips papers, what I would like to know, is how few additional components other designers get a way with. Per |

| Yes, I2c hardware on board is desired | 01/01/70 00:00 | |
