MBM29LV400TC-70PFT Datasheet
If the lead is formed, the lead should be formed up t0 5 mm from the body of the device without forming stress to the resin. Soldering should be performed after lead forming. This visible LED lamp also emits some IR light. If a photodetector is located near the LED lamp, please ensure that it will not be affected by this IR light.

When setting BCl# and BC2# at a high level or Sl# at a high lev el or S2 at a low lev el, the chips are in a non- selectable mode in which both reading and writing are disabled. In this mode, the output stage is in a high-impedance state, allowing OR-tie with other chips and memory expansion by BCl#, BC2# and Sl#, S2. The power supply current is reduced as low as 0.2pA (25aC, ty pical), and the memory data can be held at +2.OV power supply, enabling battery back-up operation during power failure or power-down operation in the non-selected mode.

(40-Pin (44-Pin Flat
Package) Package) Symbol Description
20 16 DPO/LO Dual-purpose input. Decimal point select input for voltage measurements. In logic mode, connecting this pin to VDD will turn on the "low" LCD segment. There is an internal 5ccA pull-down to DGND in volts mode only. Decimal point logic: DPl DPO Decimal Point Selected
0 0 None 0 1 DP1 1 0 DP2 1 1 DP3
21 17 DPl/HI Dual-purpose input. Decimal point select input for voltage measurements. In logic mode, connecting this pin to VDD will turn on the "high" LCD segment. There is an internal 5ccA pull-down to DGND in volts mode only.
22 18 BUZOUT Buzzer output. Audio frequency, 5kHz, output which drives a piezoelectric buzzer.
23 19 BUZIN Buzzer control input. Connecting BUZIN to VDD turns the buzzer on. BUZIN is logically ORed (internally) with the "logic level low" input. There is an internal 5ccA pull-down to DGND.
24 20 FREQ/ Voltage or frequency measurement select input. When unconnected, or connected
VOLTS to DGND, the A/D converter function is active. When connected to VDD, the frequency counter function is active. This pin has an internal 5ccA pull-down to DGND.
25 21 PKHOLD Peak hold input. When connected to VDD, the converter will only update the display if a new conversion value is greater than the preceding value. Thus, the peak reading will be stored and held indefinitely. When unconnected, or connected to DGND, the converter will operate normally. This pin has an internal 5ccA pull-down to DGND.
22 UR Underrange output. This output will be HIGH when the digital reading is 380 counts or less.
23 OR Overrange output. This output will be HIGH when the analog signal input is greater than full scale. The LCD will display "OL" when the input is overranged.
26 24 VSs Negative supply connection. Connect to negative terminal of 9V battery.
27 25 COM Analog circuit ground reference point. Nominally 3.3V below VDD.
28 26 CREF Positive connection for reference capacitor.
29 27 CREF Negative connection for reference capacitor.
30 28 VREF High differential reference input connection.
31 29 VREF Low differential reference input connection.
32 30 VIN Low analog input signal connection.
33 31 vTN High analog input signal connection.
34 32 VBUFF Buffer output. Connect to integration resistor.
35 33 CAZ Auto-zero capacitor connection.
36 34 VINT Integrator output. Connect to integration capacitor.
35 EOC/ Bidirectional pin. Pulses low (i.e., from VDD to DGND) at the end of each
HOLD conversion. If connected to VDD, conversions will continue, but the display is not updated.
37 36 OSC1 Crystal oscillator (input) connection.
38 37 OSC2 Crystal oscillator (output) connection.
39 38 OSC3 RC oscillator connection.
