Datasheet 89v51rb2
IP89V51RD28-bit 80C51 5 V low power 64 kB Flash microcontrollerwith 1 kB RAMRev. 01 — 01 March 2004Product data1.General descriptionThe P89V51RD2 IS a Datasheet 89v51rb2 an 80C51 microcontroller with 64 kB Flash and 1024 bytes of data RAM.A key feature of the P89V51RD2 is its X2 mode option The design engineer can choose to run the application with the conventional 80C51 clock rate (12 clocks per machine cycle) or select the X2 mode (6 clocks per machine cycle) to a Datasheet 89v51rb2 chieve twice the throughput at the same clock frequency. Another way to benefit from this feature is to keep the same performance by reducing the clocDatasheet 89v51rb2
k frequency by half, thus dramatically reducing the EMI.The Flash program memory supports both parallel programming and in serial In-System ProgramminIP89V51RD28-bit 80C51 5 V low power 64 kB Flash microcontrollerwith 1 kB RAMRev. 01 — 01 March 2004Product data1.General descriptionThe P89V51RD2 IS a Datasheet 89v51rb2 grammed in the end product under software control. The capability to field.'update the application firmware makes a wide range of applications possible.The P89V51RD2 is also In-Application Programmable (IAP), allowing the Flash program memory to be reconfigured even while the application is running.
