MCP2030-I/SL

The MCP2030-I/SL from Microchip Technology is an Analog Front-End (AFE) device designed for Low-Frequency (LF) sensing and bidirectional communication applications. It features three input pins for analog input signals with high detection sensitivity, capable of detecting signals as low as 3 mV PP. The device supports high modulation depth sensitivity, down to 8%.

Key electrical specifications include a typical input carrier frequency of 125 kHz and a maximum input data rate of 10 Kbps. It offers programmable antenna tuning capacitance up to 63 pF and features low standby and operating currents of 4 µA and 13 µA, respectively. The device includes 8 internal configuration registers for programmability and supports Serial Peripheral Interface (SPI™) communication.

This AFE device is optimized for low power consumption and offers various battery-saving modes. It is suitable for applications in the automotive industry, such as Passive Keyless Entry (PKE) transponders, engine immobilizers, and LF initiator sensors for tire pressure monitoring systems. It also finds use in security applications like long-range access control and parking lot entry transponders.

The MCP2030-I/SL is available in a 14-SOIC package with dimensions of 0.154" width. It operates within an industrial and extended temperature range of -40°C to +85°C.
