F - 15 February, Table 1. Memory Size. VQFP44 1. VQFP64 1. Flash bytes. XRAM bytes. Block Diagram. Timer 0. Timer 1. Port 5. Download 89C51RD2 Datasheet. It contains a 64 Kbytes Flash memory block for program and for data. The 64 Kbytes 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 V CC pin. The fully static design of the T89C51RD2 allows to reduce system power consumption by bringing the clock frequency down to any value, even DC, without loss of data. The T89C51RD2 has 2 software-selectable modes of reduced activity for further reduction in power consumption.
In the idle mode the CPU is frozen while the peripherals and the interrupt system are still operating. In the power-down mode the RAM is saved and all other functions are inoperative. F - 15 February, 1.
