8-bit Microcontroller

The W79E201 is a fast 8051 compatible Microcontroller with a redesigned processor core without wasted Clock and memory cycles. The W79E201 contains In-System Programmable (ISP) 16 KB AP Flash EPROM; 4KB LD Flash EPROM for loader program; a 256 bytes of RAM; one 8-bit digital or Analog input port (Port 1); three 8-bit bi-directional and bit-addressable I/O ports; an 1-bit port P4.0 for external ISP reboot used; three 16-bit Timer counters; one serial ports. These peripherals are supported by 8 sources two-level interrupt capability. To facilitate programming and verification, the Flash EPROM inside the W79E201 allows the program memory to be programmed and read electronically. Once the code is confirmed, the user CAN protect the code for security. The W79E201 is added 10-bit ADC with an 8 channel Analog input with digital input port. Furthermore, the W79E201A16LN, packaged in 48-pin LQFP, supports the in circuit emulation (ICE) function with JTAG Interface to the development tool. The W79E201 executes every 8051 instruction faster than the original 8051 for the same crystal speed. Typically, the instruction executing time of W79E201 is 1.5 to 3 times faster than that of traditional 8051 depending on the type of instruction. In general, the overall performance is about 2.5 times better than the original for the same crystal speed. Giving the same throughput with lower Clock speed, power consumption has been improved. Consequently, the W79E201 is a fully static CMOS design; it CAN also be operated at a lower crystal Clock By Winbond Electronics Corp America
