T83C5101/02
8-bit Low Pin Count Microcontrollers
1. Description
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
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.
