MCU Microcontroller Unit SABC501-LN - SIEMENS - 8-Bit CMOS Microcontroller

Quick Detail:

8-Bit CMOS Microcontroller

Description:

The C501-1R contains a non-volatile 8K × 8 read-only program memory, a volatile 256 × 8 read/write data memory, four ports, three 16-bit timers counters, a seven source, two priority level interrupt structure and a serial port. The C501-L is identical, except that it lacks the program memory on chip. The C501-1E contains a one-time programmable (OTP) program memory on chip.

The term C501 refers to all versions within this specification unless otherwise noted. Further, the term C501 refers to all versions which are available in the different temperature ranges, marked with SAB-C501... or SAF-C501.... .
