Applications
The ECS-80-S-5PX-TR is used as the primary clock reference in 8 MHz microcontroller applications including PIC, AVR, and STM32-based embedded systems that require a stable external crystal with minimal component count. Its surface mount 2-pin package and tape-and-reel format suit high-volume consumer electronics, IoT sensors, and industrial monitoring devices assembled on automated SMT lines. The 30 ppm frequency tolerance supports UART baud rate accuracy and USB full-speed timing within standard protocol error budgets.

Frequently Asked Questions
How does the 30 ppm frequency tolerance of ECS-80-S-5PX-TR affect UART communication accuracy at 8 MHz?
At 8.000 MHz with a 30 ppm tolerance, the crystal frequency can deviate up to 240 Hz from nominal. For UART at 115200 baud derived from an 8 MHz clock, the total allowable error budget including both transmitter and receiver is typically 4% (about 3.5% per side). A 30 ppm oscillator error contributes only 0.003% deviation, well within this budget. This tolerance level is therefore sufficient for all standard UART baud rates from 1200 to 230400 baud without additional oscillator calibration.
What is the significance of the 500 µW drive level specification for ECS-80-S-5PX-TR in low-power MCU designs?
The 500 µW maximum drive level on the ECS-80-S-5PX-TR is the maximum power the crystal can dissipate without overdrive damage or frequency pulling. Many low-power microcontrollers—such as STM32L, MSP430, and PIC24—provide a configurable oscillator drive strength. Setting the MCU drive current above the crystal's 500 µW limit can cause frequency instability or crystal failure over months of operation. Designers must configure the MCU oscillator gain to stay below this 500 µW threshold, typically achieved at 100 µW to 300 µW drive level settings.
For an IoT sensor product with a 5-year service life, how does the 5 PPM per year aging of ECS-80-S-5PX-TR affect long-term timing accuracy?
With 5 PPM aging per first year and typically reducing in subsequent years, the ECS-80-S-5PX-TR may accumulate approximately 10 to 15 PPM of total frequency shift over a 5-year product lifetime. At 8 MHz, 15 PPM represents a 120 Hz drift. For IoT applications using NTP synchronization or periodic radio time stamps, this drift is insignificant as the clock is regularly corrected. For standalone RTC-based timers without resynchronization, 15 PPM over 5 years accumulates to roughly 39 minutes of error—which must be evaluated against the application's timing accuracy requirements.
When should a designer choose ECS-80-S-5PX-TR over a TCXO for an 8 MHz clock reference?
The ECS-80-S-5PX-TR is the appropriate choice when cost and size are the primary constraints and frequency stability of 30 ppm across temperature is acceptable. A TCXO provides typically 0.5 ppm to 2.5 ppm stability but costs 5 to 20 times more and requires additional supply current of 1 mA to 5 mA. For standard microcontroller applications, USB full-speed timing, and Bluetooth Classic where 30 ppm tolerance meets protocol specifications, the ECS-80-S-5PX-TR crystal with passive load capacitors is the preferred lower-cost solution.
