EM6626- With LCD Driver

OBSOLETE PRODUCT - Ultra-Low Power

Ultra-low power Microcontroller with 4x32 LCD driver

General Description

The EM6626 is an advanced single chip low cost CMOS 4-bit microcontroller. It contains ROM, RAM, LCD driver, power on reset, watchdog timer, oscillation detection circuit, 10-bit up/down and event counter, 1ms BCD counter, prescaler, voltage level detector (Vld), serial interface and several clock functions. The low voltage feature and low power consumption make it the most suitable controller for battery, stand alone and mobile equipment. The EM6626 is manufactured using an Advanced Low Power CMOS process. The EM6626 is an improved version of EM6622, with additional features such as 32/128kHz crystal oscillator and 32/42.7/64Hz LCD frequency for optimal use in communication applications.
