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