1 Input Signal Conditioning
1.1 ECUP (A1), DRVP (B17, B18),
DRVG (C15, C16, C24)
Power (Key) switch input ECUP supplies module power
to initiate the process under control. The DRVP inputs
are wired to the Main Power Relay which will supply the
process while the MPRD signal is asserted and will hold
the module power on after the ECUP signal is removed
until the MPRD signal is released by the application (see
below). Inputs are monitored by the processor.
See Motorola MPC555 datasheet for description of processor resources.

(C6, C11, B22, B20, C23, C21,
C5, C3, B21, B19, C22, C20)
These outputs are injector coil drivers capable of sinking 3A
pk. and 1A cont.
Notes:
When the injector output is on (duration), current is
regulated to either the peak or hold level. Current regulation
is implemented via a chopper drive and the recirculation
path is via DRVP. If the output is off there is no leakage
path to DRVP and flyback energy is dissipated via low-side
avalanche. AI1D and AI2D may be used for FI7D and FI8D
respectively. Injector trace shown below:1A=470mV.

2.12 EST1...EST8
(B2, C8, B10, C7, B9, C12, C13, C14)
These are TTL level outputs.
Note: Since EST_RTN (2.13) is a direct path to the
ECU ground care must be taken not to introduce ground
loops. EST_RTN is not designed to carry any significant
current; it is a reference only. It should be open circuit
unless the smart coil electronics provides an isolated
logic ground reference. Care must also be taken not to
introduce noise on EST_RTN. Electrical transients on
EST_RTN can cause module upsets. The STOP signal
(1.13) will disable these outputs when asserted.

6. ENVIRONMENTAL RATINGS
The ECU is designed to meet automotive industry standard under hood environmental requirements for
6.1 GENERAL
12 volt systems, and also meets marine industry environmental requirements.
Validation tests included extreme operating temperatures (-40 to 105C), thermal shock, humidity, salt
spray, salt fog, immersion, fluid resistance, mechanical shock, vibration, and EMC.
It is the responsibility of the application engineer to assure that the application does not exceed the
demonstrated capabilities of the unit; vibration or thermal. It may be necessary to perform additional
tests to validate the unit
in the application.
