Universal Serial Bus Microcontroller

The EM78612 is a series of Universal Serial Bus 8-bit RISC Microcontrollers It is specifically designed for USB low speed device application and to support legacy device such as PS/2 mouse. The EM78612 also support one device address and two endpoints.. The EM78612 is implemented on a RISC architecture. It has five-level stack and six interrupt sources. The amount of General Input/Output pins is up to12. Each device has 80 bytes SRAM The ROM size of the EM78612 is 2K. These series of chips have Dual Clock mode which allows the device to run on low power saving frequency.
