• Manufacturer Part Number: EM6520
• Description: MFP version of EM6620 Ultra Low Power Microcontroller 4x8 LCD Driver
• Manufacturer: EM Microelectronic

18 EM6520 Electrical specifications
18.1 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.
18.2 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.
18.3
Note 1: This capacitor filters switching noise from VDD to keep it away from the internal logic cells.
18.4 DC characteristics - Power Supply
Conditions: Vdd=3.0V, T=25°C, unless otherwise specified
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).
