8-bit MCU Series (80C51-based)

The W79E225 is a fast, 8051 52-compatible Microcontroller with a redesigned processor core that eliminates wasted Clock and memory cycles. Typically, the W79E225 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 W79E225 CAN accomplish the same throughput with a lower Clock speed, reducing power consumption.The W79E225 provides 256 bytes of on-chip RAM; 1-KB of NVM memory Flash EPROM; 1-KB of auxiliary RAM; four 8-bit, bi-directional and bit-addressable I/O ports; an additional 4-bit port P4 and 2-bit port P5; three 16-bit Timer counters; Motion Feedback Module support; 2 UART serial ports; 1 channels of IC with master/slave capability; 1 channels of Serial Peripheral Interface (SPI), 8 channels of 12 bit PWM with configurable dead time and 8 channels of 10-bit ADC These peripherals are all supported by 20 interrupt sources with 4 levels of priority.The W79E225 also contains a 16-KB Flash EPROM whose contents may be updated in-system by a loader program stored in an auxiliary, 4-KB Flash EPROM Once the contents are confirmed, it CAN be protected for security.
