STCL1160YBFCWY5

Programmable Timers And Oscillators Overview

The STCL1160YBFCWY5 is a fixed-frequency silicon oscillator operating at 16 MHz, designed as a replacement for ceramic resonators in microprocessor clock applications. It operates on a 5 V ±10% supply with an active current of up to 1050 µA and a standby current of 3 µA when the Chip Enable (CE) pin is low. The device provides a push-pull CMOS-compatible square wave output with ±1.5% frequency accuracy over the –20 °C to +85 °C temperature range. Packaged in SOT23-5L, it features fast startup within 50 µs and requires no external components.

Programmable Timers And Oscillators Procurement Notes

This component is marked as not recommended for new design. Verify availability through authorized distributors and confirm that existing inventory meets project requirements before procurement. No new designs should utilize this part number.

Programmable Timers And Oscillators Selection Notes

Select this oscillator only if replacing legacy designs using ceramic resonators where tight timing precision is not critical. Ensure the application supports 5 V logic levels and utilizes the CE pin for power management. Consider newer alternatives for new product development due to its discontinued status.

Programmable Timers And Oscillators Part Context

Part of the STCL11xx0 family including STCL1100 (10 MHz) and STCL1120 (12 MHz). All share identical package, voltage, and feature sets but differ in fixed output frequency. The 'Y' suffix indicates 4.5–5.5 V operation, 'B' denotes ±1.5% accuracy, 'F' specifies active-high CE without pull-up, 'C' defines disable behavior, 'WY' is SOT23-5L, and '5' indicates –20 to +85 °C range.

Programmable Timers And Oscillators Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult STMicroelectronics directly for modern replacements suitable for new designs.

Programmable Timers And Oscillators FAQ

What is the maximum startup time for the STCL1160YBFCWY5?

The total startup time until oscillations stabilize within specifications is 50 µs maximum from the point when VCC reaches minimum operating voltage or the CE pin goes active.

How does the Chip Enable (CE) pin affect standby current?

When the CE pin is driven low (0 V), the oscillator enters standby mode, reducing the supply current to a typical value of 3 µA. No internal pull-up resistor exists on the CE pin, so the input level must be actively controlled.

Does the device require external capacitors or crystals?

No external components are required for oscillation. However, a minimum 0.1 µF decoupling capacitor is recommended near the VCC and GND pins for reliable operation and improved EMI immunity.
