Description
The EM6640 is an advanced single chip CMOS 4-bit
microcontroller. It contains ROM, RAM, EEPROM,
watchdog timer, oscillation detection circuit, 10 bit
up/down counter, prescaler, supply voltage level
detector (SVLD), sleep counter reset (SCR),
frequency output and SWB.
The low voltage feature and low power consumption
make it the most suitable controller for battery, stand
alone and mobile equipment. The EM66XX series is
manufactured using EM Microelectronic’s Advanced
Low Power (ALP) CMOS Process.
Typical Applications
• remote controls
• medical applications
• domestic appliance
• safety and security devices
• measurement equipment
• interactive system
• keyless entry with rolling code
