BQ32000DR

Texas Instruments · Real-time Clocks (RTC) · SOP-8

BQ32000DR from Texas Instruments, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OSCI input Oscillator input. Connect to one terminal of the 32.768-kHz crystal (nominal CL = 12 pF; Rs max 70 kΩ).
2 OSCO output Oscillator output. Connect to the other terminal of the 32.768-kHz crystal.
3 VBACK power_in Backup device power. Connects to a supercapacitor or non-rechargeable battery (operating range 1.4 V to VCC; switchover at 2.0 V typical). Integrated trickle charger sources current to this pin.
4 GND power_in Ground reference for the device.
5 SDA bidirectional I2C serial data line. Open-drain; requires external pull-up to VCC (typical 4.7 kΩ). Supports Standard (100 kHz) and Fast (400 kHz) modes.
6 SCL input I2C serial interface clock input, up to 400 kHz. Requires external pull-up to VCC (typical 4.7 kΩ).
7 IRQ output Configurable interrupt output; open-drain, active-low. Programmable via FT/FTF/OUT bits as static output, 1 Hz, or 512 Hz. Requires external pull-up to VCC (typical 4.7 kΩ). Unused during backup-supply operation.
8 VCC power_in Main device supply, 3.0 V to 3.6 V (absolute max 4 V). Place 1 µF decoupling capacitor close to this pin. Typical ICC = 100 µA.
