8-Bit Microprocessor with OTP ROM
1 General Description
www.DataSheet4U.com
EM78P417/8/9N is 8-bit microprocessors designed and developed with low-power and
high-speed CMOS technology. It is equipped with a 4K*13-bit Electrical One Time
Programmable Read Only Memory (OTP-ROM). With its OTP-ROM feature, it is able
to offer a convenient way of developing and verifying your programs. Moreover, it
provides a protect bit to guard against code intrusion, as well as 3 Code Option words
to accommodate your requirements. Furthermore you can take advantage of ELAN
Writer to easily write your development code into the EM78P417/8/9N.
2 Features
Operating voltage range: 2.3V~5.5V base on 0°C ~ 70°C (commercial)
2.5V~5.5V base on –40°C ~ 85°C (industrial)
Operating frequency range (base on 2 clocks):
• Crystal mode:DC ~ 20MHz/2clks, 5V; DC ~ 8MHz/2clks, 3V
• RC mode: DC ~ 4MHz/2clks, 5V; DC ~ 4MHz/2clks, 3V
Low power consumption:
• Less than 2.2 mA at 5V/4MHz
• Typically 15 µA, at 3V/32KHz
• Typically 1 µA, during sleep mode
4K × 13 bits on chip ROM
144 × 8 bits on chip registers (SRAM)
3 bi-directional I/O ports
8 level stacks for subroutine nesting
8-bit real time clock/counter (TCC) with selective signal sources, trigger edges, and
overflow interrupt
8-bit multi-channel Analog-to-Digital Converter with 12-bit resolution
Three Pulse Width Modulation (PWM ) with 10-bit resolution
One pair of comparators (can be set to act as an OP)
Power-down (SLEEP) mode
