ZL70101 Datasheet, PDF (1/9 Pages) Zarlink Semiconductor Inc – Medical Implantable RF Transceiver

Features
• 402-405 MHz (10 MICS channels) and
433-434 MHz (2 ISM channels)
• High data rate (800/400/200 kbps raw data rate)
• High performance MAC with automatic error
handling and flow control, typ < 1.5x10^-10 BER.
• Very few external components (3 pcs + antenna
matching)

continuous TX / RX, 1 mA low power mode)
• Ultra low power wakeup circuit (250 nA)
• Standards compatible (MICS, FCC, IEC)
Applications
• Implantable Devices e.g., Pacemakers, ICD’s,
Neurostimulators, Implantable Insulin Pumps,
Bladder Control Devices, implantable
physiological monitors
• Body area network, short range device
applications using the 433 MHz ISM band.

Description
The ZL70101 is a high performance half duplex RF
communications link for medical implantable
applications.
The system is very flexible and supports several low
power wakeup options. Extremely low power is
achievable using the 2.45 GHz ISM Band Wakeup-
receiver option. The high level of integration includes a
Media Access Controller, providing complete control of
the device along with coding and decoding of RF
messages. A standard SPI interface provides for easy
access by the application.
