Memory can always be enabled or disabled with the AT M1 and AT M0 commands. If it is at a low level, then the default will be to have it disabled. If this pin is at a high level during power-up or reset, the memory function will be enabled by default. Memory (pin 5) This input controls the default state of the memory option. Note that this signal does not have to be used for the Bus- Line (as was the case for the ELM320), since a separate J1850 Bus- drive output is provided on pin 14. J1850 Bus+ (pin 4) This active high output is used to drive the J1850 Bus+ Line to an active level. If this switching capability is not required for your application, this output can be left open-circuited. The pin will output a logic high level when a nominal 8V is required (for J1850 VPW), and will output a low level when 5V is needed (as for J1850 PWM applications). J1850 Volts (pin 3) This output can be used to control a voltage supply for the J1850 Bus+ output. If it is not used, this pin should be tied to either VDD or VSS. Care must be taken to prevent the voltage from going outside of the supply levels of the ELM327, or damage may occur. Vmeasure (pin 2) This analog input is used to measure a 0 to 5V signal that is applied to it. If unused, this pin should be connected to a logic high (VDD) level.

The following pages discuss the interface details, and show how to use the IC to вЂtalkвЂ™ to your vehicle, then concludes with two schematics to get you started.Д¬onnection Diagram PDIP and SOIC (top view) MCLRД®lm Electronics вЂ“ Circuits for the Hobbyist SAE J1850 PWM & VPWД®LM327 Pin Descriptions MCLR (pin 1) A momentary logic low applied to this input will reset the IC. The ELM327 requires few external components to make a fully functioning circuit. There are a number of other improvements as well вЂ“ a high speed RS232 option, battery voltage monitoring, and customizable features through programmable parameters, to name only a few. The result is an IC that can automatically sense and convert the most common protocols in use today. The ELM327 builds on improved versions of our proven ELM320, ELM322, and ELM323 interfaces by adding seven CAN protocols to them. The ELM327 is designed to act as a bridge between these On-Board Diagnostics (OBD) ports and standard RS232 ports. The data transfer on these interfaces follow several standards, none of which are directly compatible with PCs or PDAs.
