Description
EM78P267/467A/B/C 8-BIT MICRO-CONTROLLER FOR CONSUMER PRODUCT
Preliminary
The EM78P267/467A/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 EM78P267/467A/B/C 8-bit microcontroller instead o
