80C154 General Description

TEMIC's 80C154 and 83C154 are high performance CMOS single chip C. 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 powerconsumption. 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 V_cc= 5 V.
80C154 : ROMless version of the 83C154
80C154/83C154-12 : 0 to 12 MHz
80C154/83C154-16 : 0 to 16 MHz
80C154/83C154-20 : 0 to 20 MHz
80C154/83C154-25 : 0 to 25 MHz
80C154/83C154-30 : 0 to 30 MHz
80C154/83C154-36 : 0 to 36 MHz
80C154/83C154-L16 : Low power version V_CC : 2.7-5.5 V Freq : 0-16 MHz
