AP0825

The AP0825 is designed as one kind of 8-bit microcontroller. Ten pins of this device are dedicated power supply pins, which are more then 12% of all pins of the MQFP 80 package. These pins are arranged and grouped into power supply and ground pins and used to connect the controller to the external 5V power supply. And also it has two on-chip power supply rings. One power ring supplies the core and the peripherals (Oscillator circuit, ADC, Timer Units, SSC, USART, CAN etc.). The other one is used to feed the I/O ports (pads). Each of these two power rings is at least connected to two supply pin pairs.

In order to improve the EMC behavior of this AP0825, when using internal ROM, the C515C allows to switch off the Address Latch Enable output signal (ALE). This enhanced capability can only become active if internal ROM is used (EA=1).
