With the QFP package all VSS pins (VSS1 to VSS4) must be connected. VDD 40 44 38 I Power Supply: This is the power supply voltage for normal, idle, and power-down operation. 39–32 43–36 37–30 I/O Port 0: Port 0 is an open-drain, bidirectional I/O port. Port 0 pins that have 1s written to them float and 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 pull-ups when emitting 1s. 1–8 2–9 40–44, 1–3 I/O 7 8 8 9 2 3 I/O I/O Port 1: Port 1 is an 8-bit bidirectional I/O port with internal pull-ups, except P1.6 and P1.7 which are open drain. Port 1 pins that have 1s written to them are pulled high by the internal pull-ups and can be used as inputs. As inputs, port 1 pins that are externally pulled low will source current because of the internal pull-ups. (See DC Electrical Characteristics: IIL). Alternate functions include: SCL: I2C-bus serial port clock line. SDA: I2C-bus serial port data line. P2.0–P2.7 21–28 24–31 18–25 I/O Port 2: Port 2 is an 8-bit bidirectional I/O port with internal pull-ups. Port 2 pins that have 1s written to them are pulled high by the internal pull-ups and can be used as inputs. As inputs, port 2 pins that are externally being pulled low will source current because of the internal pull-ups. (See DC Electrical Characteristics: IIL). 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 pull-ups when emitting 1s. During accesses to external data memory that use 8-bit addresses (MOV @Ri), port 2 emits the contents of the P2 special function register. P3.0–P3.7 10–17 11, 13–19 5, 7–13 I/O 10 11 12 13 14 15 16 17 11 13 14 15 16 17 18 19 5 7 8 9 10 11 12 13 I O I I I I O O Port 3: Port 3 is an 8-bit bidirectional I/O port with internal pull-ups. Port 3 pins that have 1s written to them are pulled high by the internal pull-ups and can be used as inputs. As inputs, port 3 pins that are externally being pulled low will source current because of the pull-ups. (See DC Electrical Characteristics: IIL). Port 3 also serves the special features of the 80C51 family, as listed below: RxD (P3.0): Serial input port TxD (P3.1): Serial output port INT0 (P3.2): External interrupt INT1 (P3.3): External interrupt T0 (P3.4): Timer 0 external input T1 (P3.5): Timer 1 external input WR (P3.6): External data memory write strobe RD (P3.7): External data memory read strobe RST 9 10 4 I ALE 30 33 27 I/O Address Latch Enable: Output pulse for latching the low byte of the address during an access to external memory. In normal operation, ALE is emitted at a constant rate of 1/6 the oscillator frequency. Note that one ALE pulse is skipped during each access to external data memory. PSEN 29 32 26 O Program Store Enable: Read strobe to external program memory via Port 0 and Port 2. It is activated twice each machine cycle during fetches from the external program memory. When executing out of external program memory two activations of PSEN are skipped during each access to external data memory. PSEN is not activated (remains HIGH) during no fetches from external program memory. PSEN can sink/source 8 LSTTL inputs and can drive CMOS inputs without external pull–ups. EA 31 35 29 I External Access: If during a RESET, EA is held at TTL, level HIGH, the CPU executes out of the internal program memory ROM provided the Program Counter is less than 16384. If during a RESET, EA is held a TTL LOW level, the CPU executes out of external program memory. EA is not allowed to float. XTAL1 19 21 15 I Crystal 1: Input to the inverting oscillator amplifier and input to the internal clock generator circuits. P0.0–0.7 P1.0–P1.7 P1.6 P1.7 NAME AND FUNCTION Reset: A high on this pin for two machine cycles while the oscillator is running, resets the device. An internal diffused resistor to VSS permits a power-on reset using only an external capacitor to VDD. XTAL2 18 20 14 O Crystal 2: Output from the inverting oscillator amplifier. NOTE: To avoid “latch-up” effect at power-on, the voltage on any pin at any time must not be higher than VDD + 0.5V or VSS – 0.5V, respectively. 1998 Jan 06 6 Philips Semiconductors Product specification CMOS single-chip 8-bit microcontroller Table 1.

There are no requirements on the duty cycle of the external clock signal, because the input to the internal clock circuitry is through a divide-by-two flip-flop. However, minimum and maximum high and low times specified in the data sheet must be observed. ROM CODE PROTECTION (83C654) The 83C654 has an additional security feature. ROM code protection may be selected by setting a mask–programmable security bit (i.e., user dependent). This feature may be requested during ROM code submission. When selected, the ROM code is protected and cannot be read out at any time by any test mode or by any instruction in the external program memory space. Reset The MOVC instructions are the only instructions that have access to program code in the internal or external program memory. The EA input is latched during RESET and is “don’t care” after RESET (also if the security bit is not set). This implementation prevents reading internal program code by switching from external program memory to internal program memory during a MOVC instruction or any other instruction that uses immediate data. A reset is accomplished by holding the RST pin high for at least two machine cycles (24 oscillator periods), while the oscillator is running. To insure a good power-on reset, the RST pin must be high long enough to allow the oscillator time to start up (normally a few milliseconds) plus two machine cycles. At power-on, the voltage on VDD and RST must come up at the same time for a proper start-up. Idle Mode In the idle mode, the CPU puts itself to sleep while all of the on-chip peripherals stay active. The instruction to invoke the idle mode is the last instruction executed in the normal operating mode before the idle mode is activated. The CPU contents, the on-chip RAM, and all of the special function registers remain intact during this mode. The idle mode can be terminated either by any OSCILLATOR CHARACTERISTICS XTAL1 and XTAL2 are the input and output, respectively, of an inverting amplifier. The pins can be configured for use as an on-chip oscillator, as shown in the Logic Symbol, page 3. Table 2. 83C654 enabled interrupt (at which time the process is picked up at the interrupt service routine and continued), or by a hardware reset which starts the processor in the same manner as a power-on reset. Power-Down Mode In the power-down mode, the oscillator is stopped and the instruction to invoke power-down is the last instruction executed. Only the contents of the on-chip RAM are preserved. A hardware reset is the only way to terminate the power-down mode. The control bits for the reduced power modes are in the special function register PCON. Table 2 shows the state of the I/O ports during low current operating modes. I2C SERIAL COMMUNICATION — SIO1 The I2C serial port is identical to the I2C serial port on the 8XC552. The operation of this subsystem is described in detail in the 8XC552 section of this manual. Note that in both the 8XC652/4 and the 8XC552 the I2C pins are alternate functions to port pins P1.6 and P1.7. Because of this, P1.6 and P1.7 on these parts do not have a pull-up structure as found on the 80C51. Therefore P1.6 and P1.7 have open drain outputs on the 8XC652/4.

The input threshold voltage of P1.6 and P1.7 (SIO1) meets the I2C specification, so an input voltage below 0.3VDD will be recognized as a logic 0 while an input voltage above 0.7VDD will be recognized as a logic 1. 1998 Jan 06 10 Philips Semiconductors Product specification CMOS single-chip 8-bit microcontroller 83C654 7. Pins of ports 1 , 2, and 3 source a transition current when they are being externally driven from 1 to 0. The transition current reaches its maximum value when VIN is approximately 2V. 8. Capacitive loading on ports 0 and 2 may cause spurious noise to be superimposed on the VOLs of ALE and ports 1 and 3. The noise is due to external bus capacitance discharging into the port 0 and port 2 pins when these pins make 1-to-0 transitions during bus operations. In the worst cases (capacitive loading > 100pF), the noise pulse on the ALE pin may exceed 0.8V. In such cases, it may be desirable to qualify ALE with a Schmitt Trigger, or use an address latch with a Schmitt Trigger STROBE input. 9. Under steady state (non-transient) conditions, IOL must be externally limited as follows: Maximum IOL = 10mA per port pin; Maximum IOL = 26mA total for Port 0; Maximum IOL = 15mA total for Ports 1, 2, and 3; Maximum IOL = 71mA total for all output pins. If IOL exceeds the test conditions, VOL may exceed the related specification. Pins are not guaranteed to sink current greater than the listed test conditions. 10. Capacitive loading on ports 0 and 2 may cause the VOH on ALE and PSEN to momentarily fall below the 0.9VDD specification when the address bits are stabilizing. 11. IDDMAX for other frequencies can be derived from Figure 1, where FREQ is the external oscillator frequency in MHz.
