ZIC2410 Datasheet
1.1 FUNCTIONAL OVERVIEW
In the receive mode, the received RF signal is amplified by the Low Noise Amplifier (LNA),
down-converted to a quadrature signal and then to baseband. The baseband signal is filtered,
amplified, converted to a digital signal by the ADC and transferred to a modem. The data,
which is the result of signal processing such as dispreading, is transferred to the MAC block.
In transmit mode, the buffered data at the MAC is transferred to a baseband modem which,
after signal processing such as spreading and pulse shaping, outputs a signal through the DAC.
The Analog baseband signal is filtered by the low-pass filter, converted to RF signal by the up-
conversion mixer, is amplified by PA, and finally applied to the antenna.
The MAC block provides IEEE802.15.4 compliant hardware and it is located between
microprocessor and a baseband modem. MAC block includes FIFOs for transmitting/receiving
packet, AES engine for security operation, CRC and related control circuit. In addition, it
supports automatic CRC check and address decoding.
ZIC2410 integrates a high performance embedded microcontroller, compatible to an Intel i8051
microcontroller in an instruction level. This embedded microcontroller has 8-bit operation
architecture sufficient for controller applications. The embedded microcontroller has 4-stage
pipeline architecture to improve the performance over previous compatible chips making it
capable of executing simple instructions during a single cycle.
The memory organization of the embedded microcontroller consists of program memory and
data memory. The data memory has 2 memory areas. For more detailed explanation, refer to
the data memory section (1.2.2.)
The ZIC2410 includes 22 GPIO for the QN48 packaged device and 24 GPIO for the FG72
packaged part and various peripheral circuits to aid in the development of an application circuit
with an interrupt handler to control the peripherals. ZIC2410 uses 16MHz crystal oscillator for
RF PLL and 8MHz clock generated from 16MHz in clock generator is used for microcontroller,
MAC, and the clock of a baseband modem.
The ZIC2410 supports a voice function as follows. The data generated by an external ADC is
input to the voice block via I2S interface. After the data is received via I2S it is compressed by
the voice codec, and stored in Voice TXFIFO. The data in Voice TXFIFO is transferred to the
MAC TXFIFO and then transmitted via PHY. In contrast, the received data in MAC RXFIFO is
transferred to voice RXFIFO via DMA operation. The data in voice RXFIFO is decompressed
by the internal voice codec. The decompressed data is then transferred to the external DAC via
I2S interface.
