80C51 Microcontroller - 4T

Part No. W79E201A
Datasheet W79E201.pdf
Description The W79E201 is a fast, 8051/52-compatible microcontroller with a redesigned processor core that eliminates wasted clock and memory cycles. Typically, the W79E201 executes instructions 1.5 to 3 times faster than that of the traditional 8051/52, depending on the type of instruction, and the overall performance is about 2.5 times better at the same crystal speed. As a result, with the fully-static CMOS design, the W79E201 can accomplish the same throughput with a lower clock speed, reducing power consumption.
The W79E201 provides one eight-bit digital/analog input port (Port 1) that includes a ten-bit ADC; three eight-bit, bi-directional and bit-addressable I/O ports; a one-bit port P4.0 for external ISP reboot; three 16-bit timers / counters; and one serial port. These peripherals are supported by an eight-source, two-level interrupt capability.
To facilitate programming and verification, the W79E201 contains In-System Programmable (ISP) 16-KB AP Flash EPROM; 4-KB LD Flash EPROM for the loader program in ISP mode; and 256 bytes of RAM. The Flash EPROM allows the program memory to be read and programmed electronically. Once the code is confirmed, it can be protected for security. The W79E201 also supports the in-circuit emulation (ICE) function and a JTAG interface to the development tool for debugging
