EM78P156E datasheet



The EM78P156E is an 8-bit microprocessor with low-power and high-speed CMOS technology. There is a 1K*13-bit Electrical One Time Programmable Read Only Memory (OTP-ROM) within it. It provides a PROTECTION bit to prevent a user’s code from intruding as well as 7 OPTION bits to match the user’s requirements.

Because of the OTP-ROM, the EM78P156E offers users a convenient way to develop and verify their programs. Moreover, a user’s developed code can be programmed easily by an EMC writer.


• Operating voltage range: 2.2V~5.5V

• Available in temperature range: 0°C~70°C

• Operating frequency range: DC ~ 36MHz

• 1Kx13 bits on chip ROM

• One security register to prevent the code in the OTP memory from intruding

• One configuration register to match the user’s requirements

• 48×8 bits on chip registers (SRAM)

• 2 bi-directional I/O ports

• 5 level stacks for subroutine nesting
