2.4
System Architecture
RZ707MS Module consists of two main components: STM32F205RE (512KB flash, 128KB
SRAM) or STM32F205RG (1MB flash, 128KB SRAM), an ARM Cortex-M3 based 32-bit
microcontroller that runs Em-Fi Software and Broadcom BCM43362 Wi-Fi device. It also
includes an optional serial Flash (1MB or 2MB), an on-board chip antenna and a u.FL connector
for optional external antenna.
Voltage Input
RZ707 Module supports a flexible power supply. VBATT_WLAN, required for the Wi-Fi device,
can be in the range of 2.7V to 4.8V. VBATT_MICRO can be in the range of 1.65V to 3.6V. Vdd,
used by the microcontroller and the optional flash, can be in the range of 1.8V to 3.6V.
I/O Interface
STM32F205RE/RG offers a host of interfaces enabling a rich and flexible hardware design.
These include not only the standard interfaces such as UARTs, SPIs, I2C, I2S, GPIOs, ADCs,
DACs, and Timers but also USB for easy connectivity for data and provisioning.

Radio Frequency
BCM43362 Wi-Fi device supports 802.11bgn with the latest Wi-Fi functionality including
security and provisioning and enabling a broad range of embedded Wi-Fi products.
This module operates within the frequency range between 2412 and 2464 Mhz, which
correspond to the central frequency of channel 1 and channel 11 for IEEE 802.11 b/g/n standard.
Chip Antenna
The chip antenna included on the module (which is also used for FCC test) is manufactured by
Johanson, with part number 2450AT42B100E. The datasheet of the antenna is attached to this
document.
Crystals
There are three crystals used on the module. Two crystals connected to STM32F205RG work at
16 Mhz and 32 Khz, respectively. The single crystal connected to BM43362 works at 26 Mhz.
STM32F205RG has an internal PLL circuitry, which works at 96 Mhz when it is turned on.
Radio Power
A piece of software runs on STM32F205RG to control the radio operation. By default, the
software always transmits at full power (which is used during test for FCC certificate). ReZolt
provides software API to customers in order to lower down the transmission power from the
default state, but never beyond the default state.
Specifically, following function is provided to customers in order to lower the radio transmission
power from the default number:
Status wdd_adjust_tx_power(uint8_t pwr),
where parameter pwr is in unit of dBm and always capped by the default power number when
the software processes this function call.

Layout Guidelines
The module footprint is shown in the above figure. There are two ways of using/connecting
antennas

User Manual
11
RZ707MS-UM-081312


To use the on-module chip antenna. In this case, the Antenna Area labeled above needs to be
kept clear of copper to ensure good RF performance.
To use external antenna, via the u.FL coax connector. In this case, it is OK to overlap the
Antenna Area with copper. However, to ensure the external antenna meets the requirements
of MIC/TELEC, the user needs to contact ReZolt Corporation with detailed specification of
the antenna.
In addition to the above guidelines, note the following suggestions:


5.2
Place external bypass capacitors as close as possible to the module pins.
To achieve better communication quality, keep metallic objects away from the antenna
(either the on-module chip antenna or external antennas) as far as possible.
