DESCRIPTION EM78P247/447A/B/C 8-BIT MICRO-CONTROLLER FOR GENERAL PURPOSE PRODUCT Preliminary The EM78P247/447A/B/C is an 8-bit microprocessor with low-power, high speed CMOS technology. There are 4Kx13 bits Electical One Time Programmable Read Only Memory (OTP-ROM) within it. It provides 1 Protect bit and 6 One-time Programmable Option bits to protect the OTP memory code from any external access as well as the user's options. The OTP ROM will be incorporated into EM78P247/447A/B/C 8-bit microcontroller instead of it's original memory. The user's development program can be easily programmed into or verify from this OTP memory by using EMC OTP PROGRAMMER. FEATURES • Operating voltage range: 2.5V~5.
