ECM-S12X-070

ECM-S12X-070

Product Summary

A new Engine Control Module in the MotoHawk modules product line, these rugged controllers are capable of operating in harsh automotive, marine, and off-highway applications. Numerous marine applications have proven the capability of this family. Based on the Freescale MC9S12 family of microprocessors, the ECM-S12X-070-1001 is capable of delivering complex control strategies. The onboard floating-point unit and high clock frequency allow software to be executed in shorter times. The CAN 2.0B datalink ensures interoperability with other vehicle systems.

Features include:

Freescale MC9S12XET256, 50 MHz Microprocessor
Operating Voltage: 6.5-16 V, 24V (Jump start), 5V (crank)
Operating Temperature: -40deg C to +85deg C (105deg C in some applications)

LSD Information

Only LSO1 has current sensing. The current monitoring on LSO1 is intended for diagnostic purposes, or to indicate high vs. low motor load. The Vad=.255*lout, and is 10-bit.
PWM is supported in MotoHawk on LSO1, 2, 3, 4, 5, 6, 7, and 8. However, only LSO 2, 3, and 4 have a flyback diode and are intended to be used as PWM. They are intended to be used as a discrete output, unless the load has no stored energy.
For the LSO1 is capable capable of PWM, however the flyback diode is not sized for continuous PWM and was intended for discrete mode.
If you look at the datasheet for LSO1 it will mention an A, B, and C pin. These are not separate LSO's, but instead all three pins are parallel outputs for LSO1 to allow for a higher current output.
