EM6627- With LCD Driver

The EM6627 is an ultra-low power, low voltage microcontroller. - Display Technology

General Description

The EM6627 is an ultra-low power, low voltage microcontroller with an integrated static drive or 3/4 MUX x 20 segments LCD driver and the equivalent of 8kB program memory. It features temperature compensated LCD voltage levels, and built-in LCD voltage multiplier. It also has a melody generator, an 8x8 EEPROM and PWM function. Tools include windows-based simulator. The EM6522 programmable part can be used for must functions during program development.

Due to its very low current consumption, the EM6627 is ideal for use in battery-operated and field-powered applications.
