(obsolete) MFP version of EM6604 |
|
|
|
| |
| General description |
The EM6504 is an advanced single chip CMOS 4-bit microcontroller. It contains RAM, timer, prescaler, watchdog timer, voltage level detector and stepper motor driver capability. Its low voltage and low power operation make it the most suitable controller for battery, stand alone and mobile equipment. The EM6504 is manufactured using an Advanced Low Power CMOS Process.
