ECS Inc. — ECX-16 Tuning Fork Crystal

ECS Inc. presents an ideal timing solution for low-power real-time clock applications with its ECX-16 32.768 kHz surface-mount tuning fork crystal. This compact timing crystal is available with a footprint of just 1.6 mm x 1.0 mm, which makes it suitable for space-constrained designs such as IoT sensor nodes and consumer products. The low drive level of 0.5 μW also makes the ECX-16 crystal suitable for battery-powered devices where long operating life is key.

The ECX-16 crystals are specified with a frequency tolerance of ±20 ppm at 25°C, with an aging of ±3 ppm in the first year. This high accuracy means that the crystals are recommended by STMicroelectronics as a companion crystal for timing when using the STM32 family of microcontrollers.
