It contains a 16-KB Flash memory block for program and data. The 16-KB Flash memory can be programmed either in parallel mode or in serial mode with the ISP capability or with software. The programming voltage is internally generated from the standard VCC pin. The T89C5115 retains all features of the 80C52 with 256 bytes of in...
