Description
The EM6680 is an ultra-low voltage, low power
microcontroller coming in a package as small as 8-pin
TSSOP and working up to 0.4 MIPS. It comes with an
integrated 4-bit ADC and 2 high current drive outputs of
10mA and it requires no external component. It has a
sleep counter reset allowing automatic wake-up from sleep
mode. It is designed for use in battery-operated and field-
powered applications requiring an extended lifetime. A
high integration level make it an ideal choice for cost
sensitive applications.
The EM6680 contains the equivalent of 3kB mask ROM
and a RC oscillator with frequencies between 32 and
800kHz selectable by metal option. It also has a power-
on reset, watchdog timer, 10 bit up/down counter, PWM
and several clock functions.
Tools include windows-based simulator and emulator. A
ROMless version is also available for validation in
development stage (EMDK6680A).
