The C504 is a modified and extended version of the c501 Microcontroller. its enhanced functionality, especially the capture compare unit (CCU), allows to use the MCU in motor control applications. Further, the C504 is a compatible with the SAB 80C52/C501 microcontrollers and cam replace it in existing applications. The C504-2R contains a non-volatile 16Kx8 read-only program memory, a volatile on-chip 512×8 read/write data memory, four 8-bit wide ports, three 16-bit timer/counters, a 16-bit capture/compare unite, 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 genuine 10-bit A/D converter. The C504-L is identical to the C504-2R,except that it lacks the on-chip program memory. The C504-2E is the OTP version in the C504 microcontroller with a 16Kx8 one-time programmable (OTP) program memory. The term C504 refers to all versions within this documentation unless otherwise noted.
