In additional, Port 1 serves the functions of the following special features of the MX10C805X : Port Pin P1.0 1 P C Temperature C=0°C to 70° C I=-40° to 85° C C Package P=PDIP Q=PLCC F=PQFP ROM Size 0=64K Bytes 1=4K Bytes 2=8K Bytes 4=16K Bytes 8=32K Bytes P1.1 Alternate Function T2 (External Count Input to Timer/ Counter 2), Clock-Out T2EX (Timer/Counter 2 Capture/Reload Trigger and Direction Control) PACKAGES MX10C805 Port 2 : Port 2 is an 8-bit bidirectional I/O port with internal pullups. The port 2 output buffers can drive LS TTL inputs. 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. As inputs, Port 2 pins that are externally pulled low will source current (IIL, on the data sheet) because of the internal pullups. Port 2 emits the high-order address byte during fetches from external Program Memory and during accesses to external Data Memory that use 16-bit addresses (MOVX @DPTR). In this application it uses strong internal pullups when emitting 1's. During accesses to external Data Memory that use 8-bit addresses (MOVX @Ri), Port 2 emits the contents of the P2 Special Function Register. Port 3 : Port 3 is an 8-bit bidirectional I/O port with internal pullups. The port 3 output buffers can drive LS TTL inputs. Port 3 pins that have 1's written to them are pulled high by the internal pullups, and in that state can be used as inputs. As inputs, Port 3 pins that are externally pulled low will source current (IIL, on the data sheet) because of the internal pullups. Port 3 also serves the function of various special features of the 8051 Family, as listed below : Port Pin P3.0 P3.1 P3.2 P3.3 P3.4 P3.5 P3.6 P3.7 Alternate Function RXD (serial input port) TXD (serial output port) INT0 (external interrupt 0) INT1 (external interrupt 1) T0 (Timer 0 external input) T1 (Timer 1 external input) WR (external data memory write sttobe) RD (external data memory read strobe) PIN DESCRIPTIONS VCC : Supply voltage. VSS : Circuit ground. Port 0 : Port 0 is an 8-bit, open drain, bidirectional I/O port. As an output port each pin can sink several LS TTL inputs. Port 0 pins that have 1's written to them float, and in that state can be used as high-impedance inputs. Port 0 is also the multiplexed low-order address and data bus during accesses to external Program and Data Memory. In this application it uses strong internal pullups when emitting 1's, and can source and sink serveral LS TTL inputs. Port 1 : Port 1 is an 8-bit bidirectional I/O port with internal pullups. The port 1 output buffers can drive LS TTL inputs. 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. As inputs, Port 1 pins that are externally pulled low will source current (IIL, on the data sheet) because of the internal pullups. P/N:PM0591 REV. 0.3, APR. 09, 1999 3 MX10C805X RST : Reset input. A high on this pin for two machine cycles while the oscillator is running resets the device. The port pins will be driven to their reset condition when a minimum VIHI voltage is applied whether the oscillator is running or not. An internal pulldown resistor permits a power-on reset with only a capacitor connected to VCC. ALE : Address Latch Enable output pulse for latching the low byte of the address during accesses to external memory. In normal operation ALE is emitted at a constant rate of 1/6 the oscillator frequency, and may be used for external timing or clocking purposes. Note, however, that one ALE pulse is skipped during each access to external Data Memory. If desired, ALE operation can be disabled by setting bit 5 of SFR location 87H (PCON). With this bit set, the pin is weakly pulled high. However, the ALE disable feature will be suspended during a MOVX or MOVC instruction, idle mode, power down mode. The ALE disable feature will be terminated by reset. When the ALE disable feature is suspended or terminated, the ALE pin will no longer be pulled up weakly. Setting the ALE-disable bit has no affect if the micrcontroller is in external execution mode. Throughout the remainder of this data sheet, ALE will refer to the signal coming out of the ALE pin, and the pin will be referred to as the ALE pin. PSEN : Program Store Enable is the read strobe to external Program Memory. When the MX10C805X is executing code from external Program memory, PSEN is activated twice each machine cycle, except that two PSEN activations are skipped during each access to external Data memory. EA/VPP : Extrernal Access enable. EA must be strapped to VSS in order to enable the twiceto fetch code from external Program Memory locations 0000H to 0FFFFH. EA will be internally latched on reset. EA should be strapped to VCC for internal program executions. XTAL1 : Input to the inverting oscillator amplifier. XTAL2 : Output from the inverting oscillator amplifier. P/N:PM0591 OSCILLATOR CHARACTERISTICS XTAL1 and XTAL2 are the input and output, respectively, of a inverting amplifier which can be configured for use as an on-chip oscillator, as shown in Figure 3. Either a quartz crystal or ceramic resonator may be used. C2 XTAL2 C1 XTAL1 VSS C1, C2 = 30 pF is equal to or less than 10 pF for Crystal For Ceramic Resonators,contact resonator manufacture. Figure 3. Oscillator Connections To drive the device from an external clock source, XTAL1 should be driven, while XTAL2 floats, as shown in Figure 4. There are no requirememts on the duty cycle of the external clock signal, since the input to the internal clocking circuitry is through a divide-by-two flip-flop, but minimum and maximum high and low times specified on the data sheet must be observed. An external oscillator may encounter as much as a 100 pF load at XTAL1 when it starts up. This is due to interaction between the amplifer and its feedback capacitance. Once the external signal meets the VIL and VIH specifications the capacitance will not exceed 20 pF. N/C XTAL2 EXTERNAL OSCILLATOR SIGNAL XTAL1 VSS Figure 4. External Clock Drive Configuration REV. 0.3, APR. 09, 1999 4 MX10C805X IDLE MODE The user's software can invoke the Idle Mode. When the microcontroller is in this mode, power consumption is reduced. The Special Function Registers and the onboard RAM retain their values during Idle, but the processor stops executing instructions. Idle Mode will be exited if the chip is reset or if an enabled interrupt occurs.

If this mode, the oscillator is stopped and the instruction that invoked Power Down is the last instruction executed. The on-chip RAM and Special Function Registers retain their values until the Power Down mode is terminated. On the MX10C805X either a hardware reset or an external interrupt can cause an exit from Power Down. Reset redefines all the SFRs but does not change the onchip RAM. An external interrupt allows both the SFRs and on-chip RAM to retain their values. To properly terminate Power Down, the reset or external interrupt should not be executed before VCC is restored to its normal operating level, and must be held active long enough for the oscillator to restart and stabilize (normally less than 10 ms). With an external interrupt, INT0 and INT1 must be enabled and configured as level-sensitive. Holding the pin low restarts the oscillator but bringing the pin back high completes the exit. Once the interrupt is serviced, the next instruction to be executed after RETI will be the one following the instruction that put the device into Power Down.

Capacitive loading on Ports 0 and 2 may cause noise pulses above 0.4V to be superimposed on the VOLs of ALE and Ports 1, 2 and 3. The noise is due to external bus capacitance discharging into the Port 0 and Port 2 pins when these pins change from 1 to 0. In applications where capacitive loading exceeds 100 pF, the noise pulses on these signlas may exceed 0.8V. It may be desirable to qualify ALE or other signals with a Schmitt Triggers, or CMOS-level input logic. 2. Capacitive loading on Ports 0 and 2 cause the VOH on ALE and PSEN to drop below the 0.9 VCC specification when the address lines are stabilizing. 3. Minimum VCC for Power Down is 2V. 4. Typicals are based on a limited number of samples and are not guaranteed. The values listed are room temperature and 5V. 5. Under steady state (non-transient) conditions, IOL must be externally limited as follows: Maximum IOL per port pin: 10mA Maximum IOL per 8-bit port: Port 0: 26mA Ports 1, 2 and 3: 15mA Maximum total IOL for all output pins: 71mA If IOL exceeds the test condition, VOL may exceed the related specification. Pins are not guaranteed to sink current greater than the listed test conditions.
