8742

The 8742 is designed as universal peripheral interface 8-bit slave microcontroller.

8742 has many features. The first one is that it would be 12MHz. The next one is pin, software and architecturally compatible with 8471A. The next one is 8-bit CPU plus ROM, RAM, I/O, timer and clock in a single package. The next one is 2048 x 8 EPROM, 128 x 8 RAM, 8-bit timer / counter, 18 programmable I/O pins. The next one is on 8-bit status and teo data registers for asychronous slave to master interface. The next one is DMA, interrupt, or polled operation supported. The next one is it would be fully compatible with all intel and most other microprocessor families. The next one is it would have expandable I/O. The next one is it would have RAM power down capacility. The next one is over 90 instructions : 70% single byte. The next one it would be available in EXPRESS which means standard temperature range. That are all the main features.

Some absolute maximum ratings of 8742 have been concluded into several points as follow. The first one is about its ambient temperature under bias which would be from 0°C to +70°C. The next one is about its storage temperature range which would be from -65°C to +150°C. The next one is about its voltage on any pin with respect to ground which would be from -0.5V to +7V. The next one is about its power dissipation which would be 1.5W. It should be noted that stressing the device beyong the "absolute maximum ratings" may cause permanent damage. These are stress ratings only.

Also some DC characteristics about 8742. The first one is about its input low voltage (except XTAL1, XTAL2, RESET) which would be min -0.5V and max 0.8V. The next one is about its input low voltage (XTAL1, XTAL2, RESET) which would be min -0.5V and max 0.6V. The next one is about its input high voltage (except XTAL1, XTAL2, RESET) which would be min 2.0V and max Vcc V. The next one is about its input high voltage (XTAL1, XTAL2, RESET) which would be min 3.5V and max Vcc V. And so on. For more information about 8742 please contact us.
