80C154/83C154
CMOS 0 to 36 MHz Single Chip 8–bit Microcontroller
Description
TEMIC’s 80C154 and 83C154 are high performance
CMOS single chip µC. The 83C154 retains all the
features of the 80C52 with extended ROM capacity (16
K bytes), 256 bytes of RAM, 32 I/O lines, a 6-source
2-level interrupts, a full duplex serial port, an on-chip
oscillator and clock circuits, three 16 bit timers with extra
features : 32 bit timer and watchdog functions. Timer 0
and 1 can be configured by program to implement a 32 bit
timer. The watchdog function can be activated either with
timer 0 or timer 1 or both together (32 bit timer).
In addition, the 83C154 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 is saved, and the timers, the serial port and the
interrupt system continue to function. In the power down
mode the RAM is saved and the timers, serial port and
interrupt continue to function when driven by external
clocks. In addition as for the TEMIC 80C51/80C52, the
stop clock mode is also available.
The 80C154 is identical to the 83C154 except that it has
no on-chip ROM. TEMIC’s 80C154 and 83C154 are
manufactured using SCMOS process which allows them
to run from 0 up to 36 MHz with Vcc = 5 V.
