Description

The MCRF200 is a passive Radio Frequency Identifi-

cation (RFID) device for low-frequency applications

(100 kHz-400 kHz). The device is powered by

rectifying an incoming RF signal from the reader. The

device requires an external LC resonant circuit to

receive the incoming RF signal and to send data. The

device develops a sufficient DC voltage for operation

when its external coil voltage reaches approximately 10

VPP.

This device has a total of 128 bits of user programmable

memory and an additional 12 bits in its configuration

register. The user can manually program the 128 bits of

user memory by using a contactless programmer in a

microID developer kit such as DV103001 or PG103001.

However, in production volume the MCRF200 is

programmed at the factory (Microchip SQTP – see

Technical Bulletin TB023). The device is a One-Time

Programmable (OTP) integrated circuit and operates as

a read-only device after programming.
