BJ8P64N 8-Bit Microcontroller with OTP ROM Product Specification VER 1.0 March 12, 2010 3/12/2010 REV1.0 1/7 Free Datasheet http://www.datasheet4u.com/ 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. 2 „ Features CPU configuration z 2K*14 bits on-chip ROM z 80*8 bits on-chip registers (SRAM) z 8-level stacks for subroutine nesting z Less than 1.9 mA at 5V/4MHz z Typically 15uA, at 3V/32kHz z Typically 1 uA, during Sleep mode I/O port configuration z 3 bidirectional I/O ports : P5, P6, P7 z 17 I/O pins z Wake-up port : P5 z 8 Programmable pull-down I/O pins z 8 programmable pull-high I/O pins z 8 programmable open-drain I/O pins z External interrupt : P60 Operating voltage range z Operating voltage:2.5V~5.5V Operating temperature range z Operating temperature: -40ć ~85ć Operating frequency range z Crystal mode: DC~20MH...
