Microchip Technology, Inc. RFID, RF Access, Monitoring ICs MCP2030A-I/SL

The MCP2030A-I/SL is a three-channel analog front-end device designed for low-frequency (LF) sensing and bidirectional communication applications. It features three input pins for analog signals with high sensitivity, detecting input signals as low as 3 mVPP and modulating with a depth sensitivity of 8%. The device operates at a typical input carrier frequency of 125 kHz and supports a maximum data rate of 10 Kbps. This IC includes eight internal configuration registers, allowing for programmable settings, and offers three output selections: demodulated data, carrier clock, and RSSI (Received Signal Strength Indicator). The MCP2030A-I/SL is optimized for low power consumption, with a typical operating current of 13 ¬µA and standby current of 4 ¬µA, making it suitable for battery-powered applications. It supports battery backup and batteryless operation with external circuits. The device is available in multiple package types, including 14-pin PDIP, SOIC, and TSSOP, and is rated for industrial and extended temperature ranges from -40¬8C to +85¬8C. Typical applications include automotive systems such as passive keyless entry, remote door locks, and tire pressure monitoring systems, as well as security applications like access control and asset management.
