A high performance 80C51 CPU provides instruction cycle times of 111 ns to
222 ns for all instructions except multiply and divide when executing at 18 MHz.
This is 6 times the performance of the standard 80C51 running at the same clock
frequency. A lower clock frequency for the same performance results in power
savings and reduced EMI.
n 2.4 V to 3.6 V VDD operating range. I/O pins are 5 V tolerant (may be pulled up or
driven to 5.5 V).
n 4 kB/8 kB Flash code memory with 1 kB sectors, and 64-byte page size.
n Byte-erase allowing code memory to be used for data storage.
n Flash program operation completes in 2 ms.
n Flash erase operation completes in 2 ms.
n 256-byte RAM data memory.
n Two 16-bit counter/timers. Each timer may be configured to toggle a port output
upon timer overflow or to become a PWM output.
n Real-Time clock that can also be used as a system timer.
n Two analog comparators with selectable inputs and reference source.
n Enhanced UART with fractional baud rate generator, break detect, framing error
detection, automatic address detection and versatile interrupt capabilities.
n 400 kHz byte-wide I2C-bus communication port.
n SPI communication port.
n Eight keypad interrupt inputs, plus two additional external interrupt inputs.
n Four interrupt priority levels.
n Watchdog timer with separate on-chip oscillator, requiring no external
components. The Watchdog time-out time is selectable from 8 values.
n Active-LOW reset. On-chip power-on reset allows operation without external reset
components. A reset counter and reset glitch suppression circuitry prevent
spurious and incomplete resets. A software reset function is also available.

供应NXP LPC2194单片机
信息内容：The LPC2194 is based on a 16/32 bit ARM7TDMI-S™ CPU with real-time emulationand embedded trace support, together with 256 kilobytes (kB) of embedded highspeed flash memory. A 128-bit wide memory interface and a unique acceleratorarchitecture enable 32-bit code execution at maximum clock rate. For critical codesize applications, the alternative 16-bit Thumb Mode reduces code by more than 30%with minimal performance penalty.With its compact 64 pin package, low power consumption, various 32-bit timers,4-channel 10-bit ADC, 4 advanced CAN channels, PWM channels and 46 GPIO lineswith up to 9 external interrupt pins this microcontroller is particularly suitable forautomotive applications such as a CAN gateway that connects several CAN bussesor a CAN bridge between sub networks at different speeds. Sensors with CANinterface or debugging via CAN are additional application that need more than 2 CANinterfaces. It is also an adequate solution for industrial control, medical systems andf...
