1. Pin assignments and signals
Compatible socket:
Sumitomo 3M : V Low-Proheader
Model: 7610-5002XX or equivalent
Gage plug External device
socket
*1 : LGD, LGS uses a unique specification.
All others use the common Digimatic output specification (10-pin, square).
*2 : Current consumption of LGD,LGS: Idd=20mA max.
2. I/O electrical specifications
• Output terminal format: CK, DATA
N-channel open drain
Maximum output curr
ent: 400μA max. (when Vol=0.4V)
Output withstand voltage:
-0.3V to 7V
• Input terminal format: REQ, ORIG
Pull-up CMOS input
Inter
nal power supply voltage: Vdd= 1.35 to 1.65V
Pull-up r
esistance: R1= 10 to 100K
Ω
”H” level input voltage: VIH= .1V min.:
“L” level input voltage:
VIL= 0.3V max.
Recommended receiving circuit
Note: Since the power supply voltages are different between the gage side and the
external device side, be sure to use an open collector or open drain circuit.
Do not use CMOS output or the like.
LGSLGDStandard (for reference)
Note 1: The specifications indicated by an asterisk (*) are applicable only to LGD, LGS. All other
Digimatic output specifications are common to all models.
Note 2:
Read data only when CK is at the “L” level.
Note 3: Do not input REQ signal (fixed at “H”) while the absolute origin is being set (during t11).
Note 4: If t5, t6 and t7 are satisfied and REQ is continuously input, an output is obtained from
LGD, LGS at intervals of approximately 95ms.
Note 5:
Start inputting ORIG and REQ after two or three seconds have elapsed (the estimated
time required for internal circuit/sensor to stabilize) following power-on.
3. Data format
• Data is output as 13-digit (52-bit) based on 4 bits = 1 digit.
• Data is output in order from d1 to d13. Each digit is output in the order of LSB to
MSB.
• Measurement data is output in the order of MSD to LSD.
• The sign, measurement data, decimal position and unit are output in BCD based on
positive logic (0=L, 1=H).
