Wireless Authentication Applications | | | |
CHANDLER, Ariz. — Microchip Technology Inc. announced
its first stand-alone, analog front end (AFE) for smart, low frequency (125 kHz typical) wireless authentication
applications. The MCP2030 device is a 3-channel transponder AFE that provides programmable antenna tuning and
best-in-industry adjustable modulation depth that runs as low as 8 percent. The MCP2030 AFE is ideal for
passive-keyless-entry, tire pressure monitoring systems (TPMS), data acquisition and other wireless authentication
applications.
In addition to its superior modulation depth, the MCP2030 AFE offers adjustable, high input
sensitivity of 3 mVpp typical. Its 3 input channel architecture enables 3-axis reception for improved performance
independent of range, antenna orientation and environmental “noise.” Each channel is equipped with dynamically
selectable tuning capacitors up to 63 pF in 1pF steps to allow firmware-driven antenna tuning that improves signal
matching without expensive hand tuning. An additional configuration feature of the MCP2030 AFE is its intelligent
wake-up filter that extends battery life. The filter allows the external microcontroller to stay in low-power mode
until it detects recognized input signals. With these features, the MCP2030 AFE enables designers to create
low-cost, highly intelligent transponders like never before.
“Microchip’s innovation, exemplified
by the programmable antenna tuning and adjustable input sensitivity in the MCP2030 AFE, enables designers to address
many of the challenges they face in designing wireless authentication applications,” said Art Eck, senior product
marketing manager with Microchip’s Analog and Interface Products Division. “The MCP2030 AFE brings great flexibility
to designers, as well as superior sensitivity and non-directional response to these types of applications.”
The MCP2030 AFE communicates with a microcontroller over an SPI bus, and its features are
dynamically controllable by the external microcontroller, depending upon field application. |

Es más frecuente que la confianza sea generada por la ignorancia que por el conocimiento: son los que conocen poco y no los que conocen mucho, los que afirman tan positivamente que este o aquel problema nunca será solucionado por la ciencia.
Charles Darwin (1809-1892). |
