The MCP2030 is an independent Analog Front-End (AFE) device that can be used for low-frequency (LF) sensing and bidirectional communication applications. The device features high input detection sensitivity and high modulation depth sensitivity, with three output options for demodulated data, carrier clock, and RSSI. Typical applications include automotive and security industries.
The MCP2030 is a standalone analog front‑end (AFE) designed for low‑frequency (LF) sensing and bidirectional communication. It provides three independent input channels, each with programmable internal tuning capacitors up to 63 pF, and supports output of demodulated data, carrier clock, or RSSI current. The device operates from a low‑power supply and includes features such as a programmable output enable filter and SPI interface for configuration.
Electrical specifications include a supply voltage range of –0.3 V to +6.5 V, operating temperature from –40 °C to +85 °C, and standby currents as low as 4 µA with three channels enabled. Typical performance curves show standby and active current consumption, oscillator frequency versus temperature, and RSSI output versus input signal strength. The MCP2030 is offered in PDIP, SOIC, and TSSOP 14‑pin packages and is suitable for automotive keyless entry, tire‑pressure monitoring, and security access control applications.
