EM78P159N

EM78P159N

EM78P159N is an 8-bit microprocessor designed and developed with low-power, high-speed CMOS technology. It is quipped with 1K x 13-bits Electrical One Time Programmable Read Only Memory (OTP-ROM). It provides three PROTECTION bits to prevent user's code in the OTP memory from being intruded. 8 OPTION bits are also available to meet user's requirements.

With its OTP-ROM feature, the EM78P159N is able to offer a convenient way of developing and verifying user's programs. Moreover, user can take advantage of ELAN Writer to easily program his development code.

Features
  • Operating voltage range:?
    * 2.1V ~ 5.5V at 0°C ~ 70°C?
    * 2.3V ~ 5.5V at 40°C ~ 85°C
  • Operating frequency range (base on 2 clocks ):?
    * Crystal mode: DC ~ 20MHz at 5.0V, DC ~ 8MHz at 3.0V, DC ~ 4MHz at 2.1V?
    * ERC mode: DC ~ 4MHz at 5.0 ~ 2.1V?
    * IRC mode: 4 choices of frequencies available; I.e., 8M, 4M, 1M, & 455KHz
  • IRC mode:?
    * All these four main frequencies can be trimmed by programming with four calibrated bits in the ICE159N Simulator.?
    ?? OTP is auto trimmed by DWTR.?
    * Temperature, Voltage, and Process changes will influence the frequency drift?
    * Frequency deviation is only ±4.5% after auto trimming (based on Vdd=5V,Ta=25°C)
  • Fast set-up time only requires about 2ms in high XTAL and 32CLKS in IRC mode from wake up to operating mode
  • Low power consumption:?
    * Less then 2mA at 5V/4MHz?
    * Typically 20μA at 3V/32kHz?
    * Typically 1μA during Sleep mode
  • 1K x 13 bits on chip ROM
  • One security register to prevent intrusion of OTP memory codes
  • One configuration register to accommodate user's requirements
  • 48 x 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
  • Two clocks per instruction cycle
  • Power down (SLEEP) mode
  • Three available interruptions:?
    * TCC overflow interrupt?
    * Input-port status changed interrupt (wake up from Sleep mode)?
    * External interrupt
  • Programmable free running watchdog timer
  • 8 programmable pull-high pins
  • 8 programmable pull-down pins
  • 8 programmable open-drain pins
  • 2 programmable R-option pins
  • Package types:?
    * 18 pin DIP 300mil : EM78P159NP?
    * 18 pin SOP 300mil : EM78P159NM?
    * 20 pin SSOP 209mil : EM78P159NAS?
    * 20 pin SSOP 209mil : EM78P159NKM?
    * 99.9% single instruction cycle commands
  • The transient point of system frequency between HXT and LXT is around 400KHz
