描述 Description

EM78F668N is an 8-bit microprocessor designed and developed with low-power, high-speed CMOS technology. It is
equipped with 8K*15-bits Electrical Flash Memory, 256*8 bits in system programmable EEPROM, two comparators, three
8 bits timers, one 16 bits timer, two 10 bits PWM, 8 channels AD with 12 bits resolution, SPI, UART and I2C.
With its Flash-ROM feature, the EN78F668N is able to offer a convenient way of developing and verifying users'
programs. Moreover, users can take advantage of EMC Writer to easily program his development code.
