The MCP2030 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 which are
readable and programmable, except the read-only
STATUS register, 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 PP 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
Typical Applications:
? Automotive industry applications:
- Passive Keyless Entry (PKE) transponder
- Remote door locks and gate openers
- Engine immobilizer
- LF initiator sensor for tire pressure monitoring
systems
? Security Industry applications:
- Long range access control transponder
(Sleep, Standby, Active). The device can also be oper-
ated in Battery Back-up and Batteryless modes using a
few external components.
This device is available in 14-pin PDIP, SOIC, and
TSSOP packages. This device is also used as the AFE
in the PIC16F639.
