Port 1 also receives the low-order address byte during program verification. Port 0 also outputs the code bytes during program verification in the 80C Port 0 pins that have 1’s written to them float, and in that state can be used as high-impedance inputs.


Table 1 describes the status of the external pins during Idle mode. Diagrams are for reference only.

It can drive CMOS inputs without an external pullup. Receives the external oscillator signal when an external oscillator is used. The instruction that sets PCON. Port 2 emits the high-order address byte during fetches from external Program Memory and during datashwet to external Data.


D Fully static design. Idle and Power Down Hardware. Romless version of the 80C When set to a 1, the baud rate is doubled when the dwtasheet port is being used in either modes 1, 2 or 3.

It also receives the high-order address bits and control signals during program verification in the 80C An internal pull-down resistor permits Power-On reset using only a capacitor connected to V. For other speed and temperature range availability please consult your sales office. 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. This pin should be floated when an external oscillator is used.

EA must not be floated. In the power down mode the RAM is saved and all other functions are inoperative.

PCON is not bit addressable. D 64 K data memory space. Search field Part name Part description.

In the idle mode the CPU is frozen while the RAM, the timers, the serial port and the interrupt system continue to function. Figure 3 shows the internal Idle and Power Down clock configuration.

In this application, it uses strong internal pullups when emitting 1’s. Package sizes are not to scale. Idle mode operation allows the interrupt, serial port, and timer blocks to continue to function, while the clock to the CPU is gated off. Once in dwtasheet Idle mode the CPU status is preserved in its entirety: As inputs, Port 3 pins that are externally being pulled low will source current ILL, on the data sheet because of the pullups.


Setting this bit activates idle mode operation. Address Latch Enable output for latching the low byte of the address during accesses to external memory.

D 64 K program memory space. This operation is achieved asynchronously even if the oscillator does not start-up. D bytes of RAM. In this application it uses strong internal pullups when emitting 1’s. It can drive CMOS inputs without external pullups.

External pullups are required during program verification. Its hardware address is 87H. Double Baud rate bit. The 80C52 retains all datashete features of the Program Store Enable output is the read strobe to external Program Memory.
