∙ 12y agoBoth of them are ICs of 8051 microcontroller.
The difference between them are IC89c51 is compatible with CMOS Voltage levels and 89v51RD2 is compatible with TTL voltage levels. Meaning of "v" in IC 89v51RD2 is it is vacuum tube version.

∙ 14y ago8051 is divided in to different categories according to the memories used .
89c51 is type of 8051 only. In 89c51 we used Flash memory.

∙ 12y ago8051 and 89c51 are same architecture but difference is ROM memory .
ROM less for 8051 while ROM (flash) for 89c51.
it advanced EEPROM (flash) is difference.
