Features, Applications

TEMIC's 80C31 and 80C51 are high performance SCMOS versions of the 8051 NMOS single chip 8 bit C. The fully static design of the TEMIC 80C31/80C51 allows to reduce system power consumption by bringing the clock frequency down to any value, even DC, without loss of data. The 80C51 retains all the features of the 4 K bytes of ROM ; 128 bytes of RAM ; 32 I/O lines ; two 16 bit timers 5-source, 2-level interrupt structure ; a full duplex serial port ; and on-chip oscillator and clock circuits. In addition, the 80C51 has two 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 serial port, and the interrupt system continue to function. In the Power Down Mode the RAM is saved and all other functions are inoperative. The 80C31 is identical to the 80C51 except that it has no onchip ROM. TEMIC's 80C31/80C51 are manufactured using SCMOS process which allows them to run from to 42 MHz with VCC 5 V. TEMIC's 80C31 and 80C51 are also available at 16 MHz with V < Vcc 5.5 V and at 4 MHz with V < Vcc 5.5 V.
