SC/MC 2x0-218 PCA

200-218-001

• 8-6-09 : found on bench. MC doesn't seem to be powered (unable to program)
• (date unknown - June???) location AK-WB2

200-218-002

• 8-6-09 : running overnight stress test (+5a, -5a, +5, -5, 3sec off)
• 8-??-09 : reveived from MPD

200-218-003

• 4-27-09 : will start testing.
• needs R233 and R222 shorted (solder ball)

200-218-005

• location (IW)
• 4-16-09 : SHORTED R233 and R222 to enable local VBAT MEASUREMENT. DONT CONNECT EXTERNAL BATTERY CABLE
• location ceb benchtest (MIT), used for code dev

200-218-006

• 4-25-09 : has problem with MC reset
• 4-2-09 : start bench test at 3:10am (w/217-006), finished 2pm - works well!

200-218-007

• 10-24-09 : measure real time clock coin cell voltage as 2.626V
  • D14 : TP82 to TP42 = -0.370V
  • R128=1.3mV -> 26nA

• 4-6-09 : start bench test at 2am; finished 9:10pm (w/217-007) works well.

200-218-008

• has LIFEFIX ECO, has BATTERY ECO, has MILE ECO
• 8-30-09 : modified temp measurement for lifefix. C73=10nF, R102=2.0k
• modified for MILE encoder
• location (6-26-09) - used for CEB code development at lab

200-218-009

• location AK-WB1 ???

200-218-010

• 4-2-09 : ran bench test for 1.5 hrs with 217-010

ECOs

BATTERY ECO

Enables measurement of the battery voltage without an external battery data cable.

• solder ball / zero ohm resistor across R222 and R233

MILE ECO

Allows the EC30-MILE encoder to be connected to MC, increases output clock voltage.

• Disconnect pin6 of D10 from the signal Hall.C;

• On J10 (5pin x 1.25mm header) install a 4.7k 0603 resistor between pin 4 (5VDMC) and pin 3 (HALL_C).

• Replace R86 with a 220 ohm 0402

pinout

• 1 GND
• 2 VCC (5)
• 3 N-
• 4 N+
• 5 B-
• 6 B+
• 7 A-
• 8 A+
• 9 GND
• 10 VCC
• 11 SSI-DAT (to HALL.A)
• 12 SSI-CLK (to HALL.C)

LIFEFIX ECO

Increases cutoff frequency of the analog temperature measurement signal. The 'battery temperature' signal represents the loadwasher force.

• replace C73 w/10nF, 0402 NPO
• replace R102 w/2.0K, 1%, 0402
