T89C51RB2/RC2 is a high performance FLASH version of the 80C51 8-bit microcontrollers. It contains a 16K or 32Kbytes Flash memory block for program and data. The 16 Kbytes or 32 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 VCC pin. The T89C51RB2/RC2 retains all features of the 80C52 with 256 bytes of internal RAM, a 7-source 4-level interrupt controller and three timer/counters. In addition, the T89C51RB2/RC2 has a Programmable Counter Array, an XRAM of 1024 byte, a Hardware Watchdog Timer, a Keyboard Interface, a SPI Interface, a more versatile serial channel that facilitates multiprocessor communication (EUART) and a speed improvement mechanism (X2 mode). Pinout is the standard 40/44 pins of the C52. The fully static design of the T89C51RB2/RC2 allows to reduce system power consumption by bringing the clock frequency down to any value, even DC, without loss of data. The T89C51RB2/RC2 has 2 software-selectable modes of reduced activity and 8 bit clock prescaler 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.
