TEMIC T8xC5101/02 family is a high performance CMOS ROM, OTP, EPROM derivative of the 80C51 CMOS single chip 8-bit microcontroller.
The T8xC5101/02 family is a low pin count device where only Port 1, port 3 and 2/6 bits of a new port 4 are outputted. This prevents to do any external access, like external program memory access (fetch, MOVC) or external data memory (MOVX)
The T8xC5101/02 family retains all features of the TEMIC 80C51 with extended capacity 8Kb ROM (5102), 16Kb ROM (5101) / 16Kb EPROM/OTP (5101) , 256 bytes of internal RAM, a 6-source, 4-level interrupt system, an on-chip oscillator and three timer/counters.
In addition, the T8xC5101/02 family has an XRAM of 256 bytes, the X2 feature, a more versatile serial channel that facilitates multiprocessor communication (EUART), a dual data pointer and an improved timer 2.
The fully static design of the T8xC5101/02 family allows to reduce system power consumption by bringing the clock frequency down to any value, even DC, without loss of data.
The T8xC5101/02 family has 2 software-selectable modes of reduced activity for further reduction in power consumption. In the idle mode the CPU is frozen while the timers, the serial port and the interrupt system are still operating. In the power-down mode the RAM is saved and all other functions are inoperative.

NOTES 1. Stresses at or above those listed under " Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions may affect device reliability. 2. This value is based on the maximum allowable die temperature and the thermal resistance of the package.
