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 EM6625 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 Figure 1.
