描述 Description

GENERAL DESCRIPTION
EM78P153E is an 8-bit microprocessor with low-power and high-speed CMOS technology. It is equipped with a 512*13-bits Electrical One Time Programmable Read Only Memory (OTP-ROM). It provides a PROTECTION bit to prevent intrusion of user’s code in the OTP memory as well as 15 OPTION bits to match user’s requirements.
With its OTP-ROM feature, the EM78P153E offers users a convenient way of developing and verifying heir programs. Moreover, user developed code can be easily programmed with the EMC writer.FEATURES
• 14-lead packages : EM78P153E

• 32´ 8 bits on chip registers (SRAM, general purpose register)
• 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
• 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
• 7 programmable pull-high I/O pins
• 7 programmable open-drain I/O pins
• 6 programmable pull-down I/O pins
• Two clocks per instruction cycle
• 99.9% single instruction cycle commands
• Package types:
   * 14 pin DIP 300mil: EM78P153EP
   * 14 pin SOP 150mil: EM78P153EN
• The transient point of system frequency between HXT and LXT is around 400KHz.
