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. The added features of the T89C51RB2/RC2 are:

The AT45DB011B is a 1MB 2.7 volt only data flash ideally suited for a wide variety of digital voice, image, program code and data storage applications. Its 1,081,344 bits of memory are organized as 512 pages of 264 bytes each. In addition to the main memory, the AT45DB011B also contains one 264 byte SRAM data buffer. The buffer allows receiving of data while a page in the main memory is being reprogrammed. EEPROM emulation (bit or byte alterability) is easily handled with a self-contained three step Read-Modify-Write operation. Unlike conventional Flash memories that are accessed randomly with multiple address lines and a parallel interface, the DataFlash uses a single address line serial interface. The AT45DB011B supports single page and block erase operations.
