8-bit Low pin count Microcontrollers, 0-66 MHz

1. Description

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.
