Description
The EM6626 is an ultra-low power, low voltage
microcontroller with an integrated 3/4 MUX x 32
segments LCD driver and the equivalent of 8kB mask
ROM. It features temperature compensated LCD voltage
levels, free LCD segment allocation and built-in voltage
multipliers. It also has a melody generator, a millisecond
counter (BCD) and PWM function. Tools include
windows-based simulator and emulator. A flexible MFP
version is also available for development stage.
Due to its very low current consumption, the EM6626 is
ideal for use in battery-operated and field-powered
applications.
Typical Applications
Household appliance
Timer / sports timing devices
Medical devices
Interactive system with display
Automotive controls with display
Measurement equipment
Bicycle computers
Safety and security devices
