EM6640 - EM Microelectronic

EM6640 Low Power Microcontroller

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 .
