C504 Datasheet, PDF (4/49 Pages) Siemens Semiconductor Group – 8-Bit CMOS Microcontroller

C504
The C504 with its capture compare unit (CCU) especially provides a functionality, which allows to
use the microcontroller in motor control applications. Further, the C504 is functionally upward
compatible with the SAB 80C52/C501 microcontroller and can replace it in existing applications.
The C504-2R contains a non-volatile 16K×8 read-only program memory, a volatile on-chip 512×8
read/write data memory, four 8-bit wide ports, three 16-bit timers/counters, a 16-bit capture/
compare unit with compare timer, a 10-bit compare timer, a twelve source, two priority level interrupt
structure, a serial port, versatile fail save mechanisms, on-chip emulation support logic, and a
genuine 10-bit A/D converter. The C504-L is identical to the C504-2R, except that it lacks the
program memory on chip. Therefore, the term C504 refers to all versions within this data sheet
unless otherwise noted.
