MCP2030
Overview
The MCP2030 is a stand-alone Analog Front-End (AFE) device for Low-Frequency (LF) sensing and bidirectional communication applications. The device has eight internal Configuration registers which are readable and programmable, except the read-only STATUS register, by an external device.
- Three input pins for analog input signals High input detection sensitivity (3 mVPP, typical) High modulation depth sensitivity (as low as 8%) Three output selections: - Demodulated data - Carrier clock - RSSI Input carrier frequency: 125 kHz, typical Input data rate: 10 Kbps, maximum 8 internal Configuration registers Bidirectional transponder communication (LF talk back) Programmable antenna tuning capacitance (up to 63 pF, 1 pF/step) Programmable output enable filter Low standby current: 4 μA (with 3 channels enabled), typical Low operating current: 13 μA (with 3 channels enabled), typical Serial Peripheral Interface (SPI™) with external devices Supports Battery Back-Up mode and batteryless operation with external circuits Industrial and Extended Temperature Range: -40°C to +85°C (industrial)
