OVERVIEW
The MRF24J40 is an IEEE 802.15.4-2003 compliant
transceiver supporting MiWi, ZigBee and other pro-
prietary protocols. The MRF24J40 integrates wireless
RF, PHY layer baseband and MAC layer architectures
that can be combined with a simple microprocessor to
apply low data rate to a multitude of applications that
include home automation, consumer electronics, PC
peripherals, toys, industrial automation and more. The
MRF24J40 device integrates a receiver, transmitter,
VCO and PLL into a single integrated circuit. It uses
advanced radio architecture to minimize external part
count and power consumption. The MRF24J40
MAC/baseband provides hardware architecture for both
IEEE 802.15.4 MAC and PHY layers. It mainly consists
of TX/RX FIFOs, a CSMA-CA controller, superframe
constructor, receive frame filter, security engine and
digital signal processing module. The MRF24J40 is
fabricated by advanced 0.18
μ
m CMOS process and is
offered in a 40-pin QFN 6x6 mm
2
package.
Features are summarized in Table 1-1 and the pinout
for this device is listed in Table 1-2.
The MRF24J40 consists of four major functional
blocks:
1.
An SPI interface that serves as a communica-
tion channel between the host controller and the
MRF24J40.
Control registers which are used to control and
monitor the MRF24J40.
The MAC (Medium Access Control) module that
implements IEEE 802.3 compliant MAC logic.
The PHY (Physical Layer) driver that encodes
and decodes the analog data.
2.
3.
4.
The device also contains other support blocks, such as
the on-chip voltage regulator, security module and
system control logic.
