Description
AT89C51IC2 is a high performance Flash version of the 80C51 8-bit microcontrollers. It
contains a 32K bytes Flash memory block for program and data.
The 32K bytes 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 AT89C51IC2 retains all features of the 80C52 with 256 bytes of internal RAM, a
10-source 4-level interrupt controller and three timer/counters.
In addition, the AT89C51IC2 has a 32 kHz Subsidiary clock Oscillator, a Programmable
Counter Array, an XRAM of 1024 byte, a Hardware Watchdog Timer, a Keyboard Inter-
face, a 2-wire interface, an SPI Interface, a more versatile serial channel
that facilitates multiprocessor communication (EUART) and a speed improvement
mechanism (X2 mode).
The fully static design of the AT89C51IC2 allows to reduce system power consumption
by bringing the clock frequency down to any value, even DC, without loss of data.
The AT89C51IC2 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 AT89C51IC2 make it more powerful for applications that need
pulse width modulation, high speed I/O and counting capabilities such as alarms, motor
control, corded phones, smart card readers.
