Product Family Notes

Note for the ECM-0565-128-L707-C:

  • Same as the 0702 hardware, use ECM-0565-128-0702-C Datasheet
  • Newer firmware loader is used and a change to the SPD2 output is present.
  • on obsolete FET was changed.
  • There are no software implications to using 0707 over 0702.

Supplementary Details to Datasheet

“ECM-565-128-0701-C_ps36320_rev01.pdf” and “ECM-0565-128-0701-F_PS_36321.pdf”

ECM-065-128-0702-CP0 is a minor rev of ECM-0565-128-0701-CP0. Same datasheet applies to both.

There are a few errata on this datasheet. To clarify:

ECM-0565-128-L701-Fxx, flash (no calibratible memory) “PROD” production module. ECM-0565-128-L70x-Cxx, calibratible “DEV” module.

Woodward part# 8237-1237 rev. NEW == ECM-0565-128-0701-F (PCM128 “PROD”) Woodward part# 8237-1238 rev. A == ECM-0565-128-0702-C (PCM128 “DEV”)

The PCM128 modules are nearly identical. The “PROD” -F module has 4 extra analog inputs and 4 extra digital inputs; the “DEV” -C module has 2 wide-band oxygen (lambda) sensor inputs and 2 extra knock channels, as well as additional RAM. For the 2007 model-year, these modules have three H-bridges: 10-amp continuous, 12-amp peak. (The datasheet is being updated to reflect the higher-ampacity capability of H1 and H2, due to board layout revision.)

General Comments:

The low-side fuel injector drivers INJx may be run as 3A peak / 1A hold (all 12 injector drivers), or 7A peak / 3A hold (6 drivers as indicated). Use the “Injector Current Select” block in the MotoHawk Advanced Digital I/O library to select.

The fuel injector drivers INJx and LSDx low-side drivers may be used as PWM outputs or as discrete outputs. These outputs act as a switch to ground. When the MOSFET is ON, the module resource pin is connected internally to the module DRVGx driver ground pins. However, the hardware of the injector pins and low-side drivers is different. This means that a different duty cycle might be needed to get the same current output from each type of output. They are bot capable of 3A PWM output, but the duty cycle needed to achieve that will be different. The difference in duty cycle will depend on the type of load being driven.

The maximum current rating for the ECU terminal pins is 10 amps continuous. However, most circuits have a lower current rating depending on the type of circuit connected inside. These ratings are shown on the ECU datasheet.

For the analog and digital input circuits, the actual current draw is dependent on the wiring connections. Generally, these are either sensor transducer inputs, or potentiometer / thermistor / RTD resistive devices forming a voltage divider with the internal pull-up or pull-down circuit.

Knock circuitry difference on the Calibration (Dev) and Flash (Prod) Units

Normally there is no difference between I/O for the Development and Flash modules; However for the 128 pin module there is a difference. The difference is for pins J1-C23, J1-C24, J1-C13, and J1-C14. Pins J1-C23 and J1-C24 are the inputs for knock sensor 3 for the Development module; however J1-C23 is DGM5 and J1-C24 is DGM6 for the Flash module. Pins J1-C13 and J1-C14 are the inputs for knock sensor 4 on the Development module, and are DGM7 and DGM8 respectively for the Flash module. You might be able to select those resources in MotoHawk but they will not work once programmed.

A quick way to check if the DG5 through DG8 will work is to check the manufacture part number. Located on the bar-code label, the number is formatted 8237-XXXX. The number must read 8237-1237 or 8237-1364 to be compatible with these hardware inputs.

Shutdown Behavior

The ECM565-128 requires continuous power on the BATT pin for controlled shutdown. If BATT is still powered, then the module can shut down and cut power via the Main Power Relay when KEY_SW is cut. It won’t have controlled shutdown ability if BATT is cut on key off, since BATT is the only way to power the module. This behaviour differs from the ECM-555-{48|80} models, which can use DRVP to power the module in the event of ECUP power cut. (The 48- and 80-pin modules don’t have a separate key switch input.)

Boot Procedure

To boot the module you use a boot key. The pin the boot signal goes onto to is J1-B7.

EST 13-16/ Lamp 1-4 pins

The EST 13-16 pins on the 128 pin module can also be used as a LSD for resistance loads such as lamps. The max current that can be sinked is 1 A. However, these pins have no fly back diode, which means they cannot drive any inductive or capacitive loads, including relays. If you want to use these pins to drive capacitive or inductive loads you will need to add an external fly back diode. In such a case it would be recommended to use a proper LSD pin.

UEGO End of Life

The ECM-565-128 L or C module will be released with the HEGO removed, WW p/n 8923-1977/8237-1448.

The ECM-565-128 H or F module continues in production. It does not have EGO/HEGO, but instead UEGO. WW p/n 8923-1572/8237-1237
