Description
The EM6680 is an ultra-low voltage, low power microcontroller ing in a package as small as 8-pin TSSOP and working up to 0.4 MIPS. It es with an integrated 4-bit ADC and 2 high current drive outputs of 10m A and it requires no external ponent. It has a sleep counter reset allowing automatic wake-up from sleep mode. It is designed for use in battery-operated and fieldpowered applications requiring an extended lifetime. A high integration level make it an ideal choice for cost sensitive applications. The EM6680...
