• Manufacturer: EM Microelectronic

20 EM6521 Electrical Specification
20.1 Absolute Maximum Ratings
Stresses above these listed maximum ratings may cause permanent damage to the device.
Exposure beyond specified electrical characteristics may affect device reliability or cause malfunction.
20.2 Handling Procedures
This device has built-in protection against high static voltages or electric fields; however, anti-static precautions
should be taken as for any other CMOS component.
Unless otherwise specified, proper operation can only occur when all terminal voltages are kept within the supply
voltage range.
20.3 Standard Operating Conditions
Note 1: This capacitor filters switching noise from V
20.4 DC Characteristics - Power Supply
Conditions: V
Note 2: LCD Display NOT connected.
Note 3: For test reasons, the user has to provide a test loop with successive writing and reading of two
different addresses (5 instructions should be reserved for this measurement).
