描述 Description

The eKTF6708 is an 8-bit microprocessor designed and developed with low-power and high-speed CMOS technology. It has a built-in 6K x 16-bit programmable ROM and is equipped with touch sensors. The capacitive touch key sensor uses plastic or glass substrate as cover. The system controller converts fingertip position data into button presses, depending on finger locationand human interface context. The eKTF6708 OCD can be used to develop user program for this microcontroller and several other ELAN Flash type ICs.
