EM6540 EM Microelectronic, EM6540 Datasheet - Page 3

• Manufacturer Part Number: EM6540
• Description: (EM65xx) Mask Rom
• Manufacturer: EM Microelectronic

1.
The EM65xx is the Multiple Field Programmable Version of the corresponding EM66xx 4 bit
Microcontroller
The program ROM is replaced by non volatile memory, which can be programmed up to 100 times.
Functionally, the two types are equal, except the metal options which are defined in the following
pages.
Electrically, the MFP ‘s work above 2.0V and need more current, see the tables in the following
description.
The programming is done with the EM MFP programmer, either by putting the device onto the
programmer or connecting it with the connector at the back to your board.
Handling Procedures
This devices have 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.
Absolute maximum ratings
Power supply VDD-VSS
Input voltage
Storage temperature
Electrostatic discharge to
MIL-STD-883C method 3015
Maximum soldering conditions
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.
Ordering Information
The MFP’s should be used for engineering purposes only. No volume production must be planned.
