EM78P156E I. GENERAL DESCRIPTION EM78P156E is an 8-bit microprocessor with low-power and high-speed CMOS technology. There is a 1K*13bit 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. II. FEATURES • • • • Operating voltage range: 2.2V~5.5V Available in temperature range: 0°C~70°C Operating frequency range: DC ~ 36MHz Low power consumption: * less than 1.6 mA at 5V/4MHz * typical of 15 µA at 3V/32KHz * typical of 1 µA during the sleep mode 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 8-bit real time clock/counter (TCC) with selective signal sources, trigger edges, and overflow interrupt Two clocks per instruction cycle Power-down mode (SLEEP mode) Three available interruptions * TCC overflow interrupt * Input-port status changed interrupt (wake up from the sleep mode) * External interrupt Programmable free running watchdog timer 8 pull-high pins 7 pull-down pins 8 open-drain pins Two R-option pins Package type: SOP, SOIC and DIP 99.9% single instruction cycle commands • • • • • • • • • • • • • • • • • * This specification is subject to be changed without notice.
