Frequently Asked Questions
What is the temperature measurement resolution and accuracy of TC77-3.3MOATR?
TC77-3.3MOATR provides a 13-bit digital temperature output with a maximum accuracy of ±3°C. The 13-bit resolution corresponds to a step size of approximately 0.0625°C per LSB, enabling fine-grained thermal monitoring suitable for board-level temperature management in industrial and consumer electronics designs.
How does TC77-3.3MOATR communicate with a host microcontroller, and does it require an external ADC?
TC77-3.3MOATR uses an SPI-compatible 3-wire serial interface and outputs a direct digital temperature value, so no external ADC is required. The host microcontroller simply reads the 13-bit result over SPI, reducing firmware complexity and eliminating ADC resource contention in multi-sensor designs.
What are the physical dimensions of TC77-3.3MOATR, and is it compatible with standard SMT assembly?
TC77-3.3MOATR is housed in an SOIC-8 package measuring 4.9 mm × 3.91 mm with a body height of 1.42 mm. This standard 8-pin SOIC footprint is compatible with automated SMT pick-and-place and reflow soldering processes, and the package fits comfortably near heat sources on a densely populated PCB.
What is the lead time for TC77-3.3MOATR, and is the part in active production for industrial supply chains?
TC77-3.3MOATR has a factory lead time of approximately 7 weeks from Microchip Technology, with a YTEOL of 9 indicating continued active production. Procurement teams can plan production schedules around the 7-week lead time, and the active lifecycle status reduces supply risk for industrial designs with multi-year production commitments.
