80C52 : VCC Supply voltage VSS Circuit ground VSS1 Secondary ground (not on DIP) Provided to reduce ground bounce and improve power supply by-passing NOTE This pin is not a substitute for the VSS pin (pin 22) (Connection not necessary for proper operation ) 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 several LS TTL input.
80C52 : TEMIC’s 80C52 and 80C32 are high performance CMOS versions of the 8052/8032 NMOS single chip 8 bit µC. The fully static design of the TEMIC 80C52/80C32 allows to reduce system power consumption by bringing the clock frequency down to any value, even DC, without loss of data. The 80C52 retains all the features of the 8052 : 8 K bytes of ROM ; 256 bytes of RAM ; 32 I/O lines ; three 16 bit timers ; a 6-source, 2-level interrupt structure ; a full duplex serial port ; and on-chip oscillator and clock circuits. In addition, the 80C52 has 2 software-selectable modes of reduced activity for further reduction in power consumption. In the idle mode the CPU is frozen while the RAM, the timers, the .

80C52X2 : The Philips microcontrollers described in this data sheet are high-performance static 80C51 designs incorporating Philips’ high-density CMOS technology with operation from 2.7 V to 5.5 V. They support both 6-clock and 12-clock operation. The 8xC31X2/51X2 and 8xC32X2/52X2/54X2/58X2 contain 128 byte RAM and 256 byte RAM respectively, 32 I/O lines, three 16-bit counter/timers, a six-source, four-priority level nested interrupt structure, a serial I/O port for either multi-processor communications, I/O expansion or full duplex UART, and on-chip oscillator and clock circuits. In addition, the devices are low power static designs which offer a wide range of operating frequencies down to zero. Two .
