Description
The EM6682 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 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 EM6682 contains the equivalent of 3kB mask ROM
and a RC oscillator with frequencies between 32 and
800kHz selectable by metal option or register. 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.
