  • General Description

    The EM78P5840N/41N/42N series are 8-bit RISC architecture microcontroller devices designed and developed with low-power, high-speed CMOS technology. Each of these devices has on-chip 4K×13-bit Electrical One Time Programmable Read Only Memory (OTP-ROM). It provides a protection bit to prevent intrusion of user’s OTP memory code as well as from unwanted external accesses. A number of one-time programmable option bits are also available to meet user’s application requirements.


    ■ Operating voltage: 2.2V~5.5V at the main CLK (less than 3.58MHz)
    Main CLK fSYS < 3.58MHz: 2.2V
    Main CLK fSYS = 14.3MHz: 3.6V
    ■ IRC mode: 4MHz, 2MHz
    Voltage deviation: ±5% (2.3V~5.5V)
    Process deviation: Typ. ±3%, Max. ±5%
    Temperature deviation: ±5% (-40°C~85°C)
    ■ 4K x 13 OTP-ROM
    ■ 144 x 8 general propose RAM
    ■ 19 bi-directional and three input-only general purpose I/O
    ■ 8-level stack for subroutine nesting
    ■ 8-bit real time clock/counter (TCC)
    ■ One 8-bit counter interrupt
    ■ On-chip watchdog timer (WDT)
    ■ Single-instruction cycle commands
    ■ Three operation modes using crystal oscillator (Main clock can be programmed to 3.58 MHz or 14.3 MHz):
    ■ Two Normal mode frequency levels: 3.58 MHz and 14.3 MHz
    ■ Input port interrupt function
    ■ Dual-clock operation (Internal PLL main clock, External 32.768kHz)

    Operating Frequency Mode

    ■ Crystal mode (the XIN and XOUT pins are connected to the external crystal and capacitor)
    ■ ERIC mode (the ERCI pin connects the resistor to VDD)
    ■ IRC mode


    ■ Dual PWM (Pulse Width Modulation) with 10-bit resolution
    ■ Programmable period (or baud rate)
    ■ Programmable duty cycle


    ■ Operating voltage: 2.5V~5.5V
    ■ 8-channel 10-bit successive approximation A/D converter
    ■ Internal (VDD) reference voltage


    ■ Power-on reset

    Package Type
