EM78P156NPJ datasheet



The EM78P156NPJ is an 8 -bit microprocessor designed and developed with low -power, high-speed CMOS technology. It is equipped with 1K*13 -bits Electrical One Time Programmable Read Only Memory (OTP – ROM). It provides three PROTECTION bit to prevent user’s code in the OTP memory from being int ruded. 8 OPTION bits are also available to meet user’s requirements.

With its OTP- ROM feature, the EM78P156N is able to offer a convenient way of developing and verifying user’s programs. Moreover, user can take advantage of EMC Writer to easily program h is development code.


1. Low power consumption:
(1) Less then 2 mA at 5V/4MHz
(2) Typically 20 μA at 3V/32KHz
(3) Typically 1 μA during sleep mode

2. 1K × 13 bits on chip ROM

3. One security register to prevent intrusion of OTP memory codes

4. One configuration register to accommodate user’s requirements

5. 48× 8 bits on chip registers (SRAM, general purpose register)

6. 2 bi-directional I/O ports

7. 5 level stacks for subroutine nesting
