In this application it uses strong internal pullups when datsheet 1’s. Once in the Idle mode the CPU status is preserved in its entirety: In addition, the 80C52 has 2 software-selectable. Port 0 is also the multiplexed low-order address and data bus during accesses to external Program and Data Memory.
Setting this bit activates power down operation. Setting this bit activates idle mode operation. D bytes of RAM.
80C52 Technical Data
It can drive CMOS inputs without an external pullup. As illustrated, Power Down operation stops the oscillator. Idle And Power Down Operation.
Double Baud rate bit. The instruction that sets PCON. Port 2 pins that have 1’s written to them are pulled high by the internal pullups, and in that state can be used as inputs.
Romless version of the 80C Diagrams are for reference only.
Package sizes are not to scale. D Power control modes. In the idle mode the CPU is frozen while the RAM, the datashest, the serial port and the interrupt system continue to function.
An internal pull-down resistor permits Power-On reset using only datwsheet capacitor connected to V. Idle mode operation allows the interrupt, serial port, and timer blocks to continue to function, while the clock to the CPU is gated off.
For other speed and temperature range availability please consult your sales office.
A high level on this for two machine cycles while the oscillator is running resets the device. D 6 interrupt sources. This operation is achieved asynchronously even if the oscillator does not start-up. Port 1 pins that have 1’s written to them are pulled high by the internal pullups, and in that state can be used as inputs.
D 64 K program memory space. D Programmable serial port.
The 80C52 retains all the features of the Receives the external oscillator signal when an external oscillator is used. EA must not be floated. Output of the inverting amplifier that forms the oscillator.

Address Latch Enable output for latching the low byte of the address during accesses to external memory. As inputs, Port 3 pins that are externally being pulled low datasheett source current ILL, on the data sheet because of the pullups. Port 0 also outputs the code bytes during program verification in the 80C When set to a 1, the baud rate is doubled when the serial port is being used in either modes 1, 2 or 3.
Idle and Power Down Hardware. Figure 3 shows the internal Idle and Power Down clock configuration.
