Circuit ground potential. VCC Supply voltage during normal, Idle, and Power Down operation. Port 0 Port 0 is an 8 bit open drain bi-directional I/O port. 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. Port 0 also outputs the code bytes during program verification in the 80C52. External pullups are required during program verification. Port 0 can sink eight LS TTL inputs. Port 1 Port 1 is an 8 bit bi-directional I/O port with internal pullups. 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 being pulled low will source current (IIL, on the data sheet) because of the internal pullups. Port 1 also receives the low-order address byte during program verification. In the 80C52, Port 1 can sink/ source three LS TTL inputs. It can drive CMOS inputs without external pullups. 2 inputs of PORT 1 are also used for timer/counter 2 : P1.0 [T2] : External clock input for timer/counter 2. P1.1 [T2EX] : A trigger input for timer/counter 2, to be reloaded or captured causing the timer/counter 2 interrupt. Port 2 Port 2 is an 8 bit bi-directional I/O port with internal pullups. 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 being pulled low will source current (ILL, 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. It also receives the high-order address bits and control signals during program verification in the 80C52. Port 2 can sink/source three LS TTL inputs. It can drive CMOS inputs without external pullups. Port 3 Port 3 is an 8 bit bi-directional I/O port with internal pullups. 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 being pulled low will source current (ILL, on the data sheet) because of the pullups. It also serves the functions of various special features of the TEMIC 51 Family, as listed below. Port Pin Alternate Function P3.0 P3.1 P3.2 P3.3 P3.4 P3.5 P3.6 P3.7 RXD (serial input port) TXD (serial output port) INT0 (external interrupt 0) INT1 (external interrupt 1) TD (Timer 0 external input) T1 (Timer 1 external input) WR (external Data Memory write strobe) RD (external Data Memory read strobe) Port 3 can sink/source three LS TTL inputs. It can drive CMOS inputs without external pullups. RST A high level on this for two machine cycles while the oscillator is running resets the device. An internal pull-down resistor permits Power-On reset using only a capacitor connected to V CC . As soon as the Reset is applied (Vin), PORT 1, 2 and 3 are tied to one. This operation is achieved asynchronously even if the oscillator does not start-up. ALE Address Latch Enable output for latching the low byte of the address during accesses to external memory. ALE is activated as though for this purpose at a constant rate of 1/6 the oscillator frequency except during an external data memory access at which time one ALE pulse is skipped. ALE can sink/source 8 LS TTL inputs. It can drive CMOS inputs without an external pullup.

Rev. G (14 Jan. 97) 9MA TRA MHS 80C52 with Secret ROM TEMIC offers 80C52 with the encrypted secret ROM option to secure the ROM code contained in the 80C52 microcontrollers. The clear reading of the program contained in the ROM is made impossible due to an encryption through several random keys implemented during the manufacturing process. The keys used to do such encryption are selected randomwise and are definitely different from one microcontroller to another. This encryption is activated during the following phases : – Everytime a byte is addressed during a verify of the ROM content, a byte of the encryption array is selected. – MOVC instructions executed from external program memory are disabled when fetching code bytes from internal memory. – EA is sampled and latched on reset, thus all state modification are disabled. For further information please refer to the application note (ANM053) available upon request. 80C52 with Secret TAG TEMIC offers special 64-bit identifier called “SECRET TAG” on the microcontroller chip. The Secret Tag option is available on both ROMless and masked microcontrollers. The Secret Tag feature allows serialization of each microcontroller for identification of a specific equipment. A unique number per device is implemented in the chip during manufacturing process. The serial number is a 64-bit binary value which is contained and addressable in the Special Function Registers (SFR) area. This Secret Tag option can be read-out by a software routine and thus enables the user to do an individual identity check per device. This routine is implemented inside the microcontroller ROM memory in case of masked version which can be kept secret (and then the value of the Secret Tag also) by using a ROM Encryption. For further information, please refer to the application note (ANM031) available upon request.

Rev. G (14 Jan. 97) 19MA TRA MHS Clock Waveforms This diagram indicates when signals are clocked internally. The time it takes the signals to propagate to the pins, however, ranges from 25 to 125 ns. This propagation delay is dependent on variables such as temperature and pin loading. Propagation also varies from output to output and component. Typically though (T A = 25°C fully loaded) RD and WR propagation delays are approximately 50 ns. The other signals are typically 85 ns. Propagation delays are incorporated in the AC specifications.
