Description

The MCP2030A is a stand-alone Analog Front-End

(AFE) device for Low-Frequency (LF) sensing and bidi-

rectional communication applications. The device has

eight internal configuration registers. These registers,

with the exception of the read-only Status register, are

readable and programmable by an external device.

The device has three low-frequency input channels.

Each input channel can be individually enabled or dis-

abled. The device can detect an input signal with ampli-

tude as low as ~1 mV

and can demodulate an

amplitude-modulated input signal with as low as 8%

modulation depth. The device can also transmit data by

clamping and unclamping the input LC antenna

voltage.

The device can output demodulated data, carrier clock,

or RSSI current, depending on the register setting. The

demodulated data and carrier clock outputs are avail-

able on the LFDATA pin, while the RSSI output is avail-

able on the RSSI pin. The RSSI current output is

linearly proportional to the input signal strength.

The device has programmable internal tuning capaci-

tors for each input channel. The user can program

these capacitors up to 63 pF, 1 pF per step. These

internal tuning capacitors can be used effectively for

fine-tuning of the external LC resonant circuit.

The device is optimized for very low current consump-

tion and has various battery-saving low-power modes

(Sleep, Standby, Active). The device can also be oper-

ated in Battery Backup and Batteryless modes using a

few external components.

This device is available in 14-pin PDIP, SOIC, and

TSSOP packages.
