BJ8P64N Specification
1 General Description
The BJ8P64N is an 8-bit microprocessor designed and developed with low-power and high-speed
CMOS technology. The device has an on-chip 2K*14-bit Electrical One Time Programmable Read
Only Memory (OTP-ROM). It provides a protection bit to prevent intrusion of user’s code. Three
Code option words are also available to meet user’s requirements.
With its enhanced OTP-ROM feature, the BJ8P64N provides a convenient way of developing and
verifying user’s programs. Moreover, this OTP device offers the advantages of easy and effective
program updates, using development and programming tools. User can avail of the BJX Writer to
easily program his development code.
