Description
- ASK, FSK, PSK
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.
• Data Encoding options:
- NRZ Direct, Differential Biphase, Manchester
Biphase
• Die, wafer, COB, PDIP or SOIC package options
• Factory programming options
Application
• Low-cost alternative for existing low-frequency
RFID devices
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.
