TSC87C52

www.DataSheet4U.com TSC87C52 CMOS 0 to 33 MHz Programmable 8–bit Microcontroller Description TEMIC’s TSC87C52 is high performance CMOS EPROM version of the 80C52 CMOS single chip 8 bit microcontroller. The fully static design of the TSC87C52 allows to reduce system power consumption by bringing the clock frequency down to any value, even DC, without loss of data. The TSC87C52 retains all the features of the 80C52 with some enhancement: 8 K bytes of internal code memory (EPROM); 256 bytes of internal data memory (RAM); 32 I/O lines; three 16 bit timers one with count–down and clock–out capability; a 6-source, 2-level interrupt structure; a full duplex serial port with framing error detection; a power off flag; and an on-chip oscillator. The TSC87C52 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 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 TSC87C52 is manufactured using non volatile SCMOS process which allows it to run up to: D D 33 MHz with VCC = 5 V ± 10%. 16 MHz with 2.7 V < VCC < 5.5 V.
