BR16F84-1.07 OBD II Interface Chip Data Sheet For PWM, VPW, and ISO 9141-2 Vehicles VPW (general motors), PWM (Ford products), and ISO 9141-2 (Asian/European) Final Release Date: Jul 8 2001 Firmware Version: 1.07 Chip ID# 107F If you are using a completed unit, you don't need to read this data sheet. This data sheet is intended for those who are building their own hardware using the BR16F84-1.07 Chip, or writing custom software to employ this device in a particular application. GENERAL DESCRIPTION: This device is a CMOS microcontroller which is designed to interface a personal computer or laptop with a vehicle's On Board Diagnostic (OBD II) interface. It is intended to function with all three of the protocols used by vehicle manufacturers to implement the OBD II system as defined by SAE and ISO specifications. The OBD II system became mandatory for 1996 and up vehicles, but some vehicles were already fully or partially compatible with OBD II requirements prior to 1996. The chip is not suitable for the earlier vehicles such as OBD I. The device is intended to function as a simple scan tool and is capable of sending and receiving any OBD II message defined in SAE J1979 for any of the three types of OBDII bus implementations (PWM, VPW, ISO 9141-2). It can also be used as an inexpensive interface for custom instrumentation monitoring various vehicle parameters such as speed, RPM, coolant or intake air temperature, engine load, intake air flow rate, etc. FEATURES: Operating ...
