General Description
EM88F758N is an 8-bit microprocessor designed and developed with low-power, high-speed
CMOS technology. It has an on-chip 8K16-bit electrical flash memory and 2568-bit in system
programmable EEPROM.
The debug function is built in EM88F758N chip. User can read the program code from JTAG port
and monitor the on-chip register status, memory and program trace log on computer.
EM88F758N includes a capacitive touch-sensitive function. The self-contained capacitive touch
key 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 ELAN flash types IC.
