What are the key features of 7XZ-32.768KBA-T?
- 32.768 kHz CMOS output oscillator with tri-state enable/disable function, allowing the clock output to be gated off to reduce power consumption in battery-operated devices
- 3.3 V supply voltage with 3 mA current draw in a compact 4-SMD no-lead surface mount package, ideal for space-constrained real-time clock and low-power timer circuits
- Operating temperature range of -10°C to +70°C with 15 pF output load drive capability and maximum 200 ns fall time for clean CMOS logic interfacing
What is 7XZ-32.768KBA-T used for?
The 7XZ-32.768KBA-T provides a stable 32.768 kHz clock reference for real-time clock (RTC) modules, microcontroller sleep-mode timekeeping, and wearable device timers operating from a 3.3 V supply. Its enable/disable tri-state feature makes it particularly well suited for power-managed IoT nodes, portable medical devices, and smart meters where the oscillator output can be gated off during sleep states to conserve battery energy in -10°C to +70°C environments.

Frequently Asked Questions
Why is 32.768 kHz the standard frequency for real-time clock circuits, and how does the 7XZ-32.768KBA-T support this?
32.768 kHz equals exactly 2^15 Hz, allowing a 15-stage binary divider to produce a precise 1 Hz tick from a single counter chain. The TXC 7XZ-32.768KBA-T delivers this frequency from a 3.3 V CMOS oscillator with 15 pF output load capability, directly driving RTC chips and microcontroller timer inputs without additional frequency division hardware.
How does the enable/disable tri-state function of the 7XZ-32.768KBA-T help reduce power consumption in battery-operated designs?
The tri-state enable/disable pin allows the MCU or power management IC to gate off the 32.768 kHz CMOS output during deep sleep, eliminating the 3 mA supply current draw and reducing dynamic switching losses on the clock line. This is valuable in IoT sensors and wearables targeting sub-microamp standby current budgets where every milliamp-hour of battery life matters.
What output load and signal timing specifications should designers verify when interfacing the 7XZ-32.768KBA-T with an MCU timer input?
Designers should confirm the MCU timer input presents no more than 15 pF capacitive load to maintain oscillator output integrity. The maximum fall time of 200 ns at 32.768 kHz (period of approximately 30.5 µs) is well within standard CMOS input timing requirements, ensuring clean logic transitions when driving microcontroller RTC or wake-up timer inputs operating at 3.3 V.
