EM6682- Multi I/O

The EM6682 is an ultra-low voltage, low power microcontroller. - Ultra-Low Power

General Description

The EM6682 is an ultra-low voltage, low power microcontroller coming in a package as small as 8-pin SOP 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. The EM6682 simulator is usable for most of the EM6682 functions.
