1. GENERAL DESCRIPTION

BJ8P508/153 is an 8-bit microprocessor with low-power and high-speed CMOS technology. It is equipped

with a 1024*13-bits Electrical One Time Programmable Read Only Memory (OTP-ROM) with

it. It provides a PROTECTION bit to prevent intrusion of user’s code in the OTP memory

well as 15 OPTION bits to match user’s rquirements.

With its OTP-ROM feature, the BJ8P508/153 offers users a convenient way of developing and verifying

their programs. Moreover, user developed code can be easily programmed with the EMC writer.
