It integrates a 2.4 GHz RF transceiver with an IEEE802.15.4 compliant Baseband/MAC block within a single chip. The HRF24A13AN can be controlled by a microprocessor (e.g. 8051) for low-data-rate applications such as home automation, industrial automation, consumer electronics, PC peripheral …etc. For medium-data-rate applications like wireless voice and image transmission, the HRF24A13AN provides 1M/2M bps turbo mode. FIGURE 2: BLOCK DIAGRAM TABLE 1-1: PIN DESCRIPTION FIGURE 3: MICROCONTROLLER TO HRF24A13AN INTERFACE ©2013 Honeycomb Technologies Advance Information Page 7 HRF24A13AN Mounting Details The HRF24A13AN is a surface mountable module. Module dimensions are shown in Figure 4. The module Printed Circuit Board (PCB) is 0.032" thick with castellated mounting holes on the edge. Figure 5 is a recommended host PCB footprint for the HRF24A13AN. The HRF24A13AN has an integrated PCB antenna. For the best performance, follow the mounting details shown in Figure 6. It is recommended that the module be mounted on the edge of the host PCB and an area around the antenna, approximately 1.2", be kept clear of metal objects. A host PCB ground plane around the HRF24A13AN acts as a counterpoise to the PCB antenna. It is recommended to extend the ground plane at least 0.4" around the module. FIGURE 4: MODULE DETAILS FIGURE 5 RECOMMENDED PCB FOOTPRINT ©2013 Honeycomb Technologies Advance Information Page 8 HRF24A13AN FIGURE 6 MOUNTING DETAILS CIRCUIT DESCRIPTION ©2013 Honeycomb Technologies Advance Information Page 9 HRF24A13AN The HRF24A13AN is a complete 2.4 GHz IEEE 802.15.4-2006 compliant surface mount module with integrated crystal, internal voltage regulator, matching circuitry and PCB antenna. The HRF24A13AN module interfaces to many popular micro-controllers via a 4-wire serial SPI interface, interrupt, wake, Reset, power and ground. SCHEMATIC A schematic diagram of the module is shown in Figure 7 and the Bill of Materials (BOM) is shown in Table 2. The HRF24A13AN module is based on the Ubec Technology US2400 IEEE 802.15.4-2006 GHz RF Transceiver IC. The serial I/O (SCK, SDI, SDO and CS), RESET, WAKE, INT and CLKOUT pins are brought out to the module pins. The SDO signal is tri-state buffered by IC2 to solve a silicon errata where the SDO signal does not release to a high-impedance state after the CS pin returns to its inactive state. Crystal Y1 is a 32 MHz crystal with a frequency tolerance of ±20 ppm @ 25°C to meet the IEEE 802.15.4-2006 symbol rate tolerance of ±40 ppm. A balun is formed by components: C21,C2 and R1. C5 is a DC block capacitor.

The layers are shown in Figure 8 through Figure 9. The stack up of the PCB is shown in Figure10 FIGURE 8 TOP COPPER FIGURE 9 BOTTOM COPPER ©2013 Honeycomb Technologies Advance Information Page 11 HRF24A13AN FIGURE 10 PCB LAYER STACK UP PCB Antenna The PCB antenna is fabricated on the top copper trace. Figure 11 shows the trace dimensions. The layers below the antenna have no copper traces. The ground and power planes under the components serve as a counterpoise to the PCB antenna. Additional ground plane on the host PCB will substantially enhance the performance of the module.
