Overview
The BT816Q-T is a video IC from the Bridgetek EVE ASTC series, designed for resistive touch applications with an 800x600 pixel display resolution. It integrates 1MB of RAM and operates on a 3.3V supply voltage with a typical current consumption of 22 mA. The device features an SPI interface and is housed in a VQFN-64 package suitable for surface mount technology. It supports a wide operating temperature range from -40°C to +85°C and includes humidity sensitivity protection.
Feature Summary
- Integrated 1MB RAM for graphics and touch data storage
- Supports 800x600 pixel resolution with resistive touch capability
- SPI interface for efficient communication
- Operating temperature range: -40°C to +85°C
Applications
- Industrial control panels requiring resistive touch input
- Medical devices needing reliable touch interfaces
- Automotive infotainment systems within specified temperature ranges
Procurement Notes
Verify RoHS compliance details through official Bridgetek documentation before procurement. Confirm moisture sensitivity handling procedures are followed during storage and assembly. Ensure the VQFN-64 footprint matches your PCB design specifications. Check for any specific ordering suffixes that may affect packaging or performance characteristics.
Selection Notes
Select the BT816Q-T when a resistive touch solution is required alongside high-resolution graphics processing. Compare against capacitive touch variants like the BT815Q-T if environmental conditions favor different touch technologies. Consider the 1MB RAM capacity for complex UI designs. Verify power supply stability at 3.3V to ensure optimal operation within the specified current limits.
Part Context
The BT816Q-T belongs to the BT816Q series of EVE ASTC video controllers. It shares the same package and core architecture with other models in the series but differs in touch technology support. This model specifically targets resistive touch applications, distinguishing it from capacitive touch counterparts like the BT817Q-T which offers multi-touch capabilities.
Replacement Considerations
Direct replacements within the same family include the BT816Q-R for reel packaging options. For capacitive touch requirements, consider the BT815Q-T or BT817Q-T series. Ensure pin compatibility and software library support when substituting with related models.
