DS1340Z-33+T&R from Analog Devices Inc Maxim Integrated, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCC | power_in | Primary power supply operating from 2.97V to 5.5V for the DS1340Z-33 variant. |
| 2 | FT/OUT | tri_state | Open-drain frequency test/output pin; outputs 512Hz when FT=1 or OUT bit value when FT=0. |
| 3 | SCL | input | I2C serial clock input for synchronizing data movement on the I2C bus. |
| 4 | SDA | bidirectional | Open-drain I2C serial data input/output for bidirectional communication on the I2C bus. |
| 5 | VBACKUP | power_in | Backup power supply (1.3V to 5.5V for DS1340Z-33) that maintains timekeeping during VCC failure. |
| 6 | GND | power_in | Ground reference. |
| 7 | X2 | passive | Oscillator output for 32.768kHz quartz crystal with 12.5pF load capacitance. |
| 8 | X1 | passive | Oscillator input for 32.768kHz quartz crystal (12.5pF load capacitance) or external oscillator. |
