MCP2030A

Three-Channel Analog Front-End Device

with 1 mV_PPInput Detection Sensitivity

Device Features

Description

• Three input pins for analog input signals

• High input detection sensitivity (1 mV_PP, typical)

• High modulation depth sensitivity (as low as 8%)

• Three output selections:

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.

- Demodulated data

- Carrier clock

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_PPand 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.

- RSSI

• Input carrier frequency: 125 kHz, typical

• Input data rate: 10 Kbps, maximum

• Eight internal configuration registers

• Bidirectional transponder communication

(LF talk back)

• Programmable antenna tuning capacitance

(up to 63 pF, 1 pF/step)

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.

• Programmable output-enable filter

• Low standby current: 6.5 µA (with three channels

enabled), typical

• Low operating current: 19 µA (with three channels

enabled), typical

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.

• Serial Peripheral Interface (SPI) with external

devices

• Supports Battery Backup mode and batteryless

operation with external circuits

• Industrial and Extended Temperature Range:

-40°C to +85°C (industrial)

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.

Typical Applications

• Automotive industry applications:

- Passive Keyless Entry (PKE) transponder

- Remote door locks and gate openers

- Engine immobilizer

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

TSSOP packages.
