Product Description
Microchip MICRF220AYQS is a sub-1GHz RF receiver designed for reliable wireless communication in industrial and automotive applications. It supports OOK (On-Off Keying) and ASK (Amplitude Shift Keying) modulation techniques, operating specifically within the 300 to 450MHz ISM band. The component comes in a surface mount 16-pin QSOP package with precise dimensions of 4.9mm in length, 3.91mm in width, and 1.47mm in height, suitable for compact PCB designs.
The receiver boasts high sensitivity with a threshold of -110dBm at 1kbps ensuring reliable signal detection at low power levels. It offers data rates up to 20kbps, making it appropriate for low to moderate speed wireless data applications. The operating voltage lies between 3V and 3.6V, enabling efficient power consumption in portable and automotive devices. Its robust operating temperature from -40°C to +105°C confirms suitability for harsh environments and automotive-grade use cases.
The analogue RSSI output ranges up to 60dB, allowing for effective signal strength monitoring and tuning. The MICRF220AYQS supports two operating frequency bands and does not include automotive-specific certifications but fits well within general RF communication roles.
This receiver is widely used in remote control systems, including automotive keyless entry, alarm systems, and other industrial wireless modules where reliability and signal quality are critical. Its surface mount QSOP form factor enables automated assembly and miniaturized device footprints.
The device employs OOK and ASK modulation suited for simple and reliable data transmissions. High sensitivity receiver capable of detecting signals down to -110dBm. Compact 16-Pin QSOP package with dimensions optimized for dense PCB layouts.
Wide operating voltage range of 3.0 to 3.6V with low power consumption. Robust operating temperature range from -40°C to 105°C. Analogue RSSI output range of 60dB for signal strength monitoring. Supports two frequency bands in the sub-1GHz ISM range.
Ideal for automotive keyless entry and remote control applications. Explore a full range of RF ICs and semiconductor solutions on EnvMart for your industrial and commercial electronics development needs.
