EM88F752N数据手册Elan中文资料规格书

描述 Description

The EM88F752N is an 8-bit microprocessor designed and developed with low-power, high-speed CMOS technology. It has an on-chip 2K x 16-bits electrical flash memory. Debug function is built in the EM88F752N chip. User can read the program code from JTAG port and monitor the on chip register status, memory and program trace log on computer. The EM88F752N includes a capacitive touch-sensitive function. The capacitive touch key, a self-contained, is covered with a plastic or glass case. The system controller converts finger data to button presses, depending on finger location and human interface context. Using OCDS, user can develop their program for several flash types IC of ELAN
