DFZM-E72xx 3-2.Block Diagram Description 3-2-1.Overview DFZM-E72xx module is a highly integrated ZigBee system-on-chip (SOC) that contains the following: The module includes Silicon Labs EM357 SoC, which contains CPU- and memory-related, peripherals-related, clocks and power management-related in a single package. The module features an IEEE802.15.4-compliant radio transceiver with onboard 24 MHz crystal circuitries, RF, and certified antenna or external antenna options.
DFZM-E72xx developer to assist in tracking down and fixing issues. Figure 3.3 shows the EM357 ARM® Cortex-M3 memory map.
DFZM-E72xx 3-2-3.Clocks and Power Management The DFZM-E72xx integrates four oscillators: 12 MHz RC oscillator 24 MHz crystal oscillator 10 kHz RC oscillator Figure 3-4 shows a block diagram of the clocks in the DFZM-E72xx.
DFZM-E72xx The DFZM-E72xx’s power management system is designed to achieve the lowest deep sleep current consumption possible while still providing flexible wakeup sources, timer activity, and debugger operation. The DFZM-E72xx has four main sleep modes: Idle Sleep: Puts the CPU into an idle state where execution is suspended until any interrupt occurs. All power domains remain fully powered and nothing is reset. Deep Sleep 1: The primary deep sleep state.
DFZM-E72xx 3-2-4.Peripherals The DFZM-E72xx has 22 multipurpose GPIO pins, which may be individually configured as: General purpose output General purpose open-drain output Alternate output controlled by a peripheral device Alternate open-drain output controlled by a peripheral device Analog General purpose input General purpose input with pull-up or pull-down resistor The GPIO signal assignments are shown in Table 3-1.

DFZM-E72xx 6-2.Layout Guidelines Keep out area for onboard antenna. All layers on the PCB must be clear. (i.e. No GND, Power trace/plane, traces.) Note: If guidelines are not followed, DFZM-E72xx range with onboard antenna will be compromised. Figure 6-3: DFZM-E72xx module onboard antenna keep-out layout guidelines (in mm) Notes: 1. All Dimensions are in mm. Tolerances shall be ±0.10 mm. 2. Absolutely no metal trace or ground layer underneath this area. 3.
DFZM-E72xx Do not use a metallic or metalized plastic for the end product enclosure. Recommendation is to keep plastic enclosure clearance of 1cm from top and bottom of the DFZM-E72xx onboard antenna keep-out area, if possible. 5-mm (0.2 in) clearance shall be the minimum as shown in Figure 6-4. Figure 6-4 Recommended clearance above and below the PCB trace antenna 6-2-1.Surface Mount Assembly The reflow profile is shown in Figure 6-5.
DFZM-E72xx Note: 1. Perform adequate test in advance as the reflow temperature profile will vary accordingly to the conditions of the parts and boards, and the specifications of the reflow furnace. 2. Be careful about rapid temperature rise in preheat zone as it may cause excessive slumping of the solder paste. 3. If the preheat is insufficient, rather large solder balls tend to be generated. Conversely, if performed excessively, fine balls and large balls will generate in clusters at a time. 4.
DFZM-E72xx 6-3.Recommended Stencil Aperture Note: The thickness of the stencil should be 0.15mm over this area.
