Description

The RYZ012 is a highly integrated multi-standard wireless

communication module that provides a qualified solution for

Bluetooth™ 5 Low Energy (LE) and several IEEE 802.15.4 based

communication standards. The integrated RISC processor runs the

network stack and can execute the user application.

The integrated Bluetooth 5 Low Energy chipset, a multi-standard

wireless SoC solution with internal Flash and audio support,

combines the features and functions needed for 2.4GHz IoT

standards into a single SoC. The RYZ012 supports concurrent

multi-standards, and for some use cases, the RYZ012 can

concurrently run two standards. For example, stacks such as

Bluetooth Low Energy and 802.15.4 can run concurrently with one

application state but with dual radio communication channels that

are used to interact with different devices. Working in this mode,

the end product can maintain active connections to smart phones

or other Bluetooth Low Energy devices while controlling and

communicating with 802.15.4 or other 2.4GHz devices. In this case,

the end product complies with the Bluetooth standard, supports

Bluetooth Low Energy specification up to Bluetooth 5 and allows

simple connectivity with Bluetooth Low Energy mobile phones,

tablets and laptops. The Bluetooth Low Energy stack supports

Bluetooth Low Energy slave and master mode operation, including

broadcast, encryption, connection updates, and channel map

updates. Combining Bluetooth Low Energy with IEEE 802.15.4

based standards such as ZigBee or Thread, creates an

interoperable solution for use within the home.

The RYZ012 integrates hardware acceleration to support the

complicated security operations required by HomeKit, Thread, and

other standards without the requirement for an external DSP,

resulting in a significant reduction in the product eBOM. The

RYZ012 also supports single or dual analog microphones or a

digital microphone along with stereo audio output with enhanced

voice performance for voice search and similar applications.

Including a full range of on-chip peripherals, the RYZ012 interfaces

with external components such as LEDs, sensors, touch controllers,

keyboards, external processors, and motors.

RYZ012 4. Multi-Standard Wireless Communication Module for Bluetooth 5 Low Energy and 802.15.4 Interrupt System The RYZ has 24 interrupt lines that can interrupt normal program flow, allowing quick handling of external or internal events. When an interrupt is triggered, the normal program flow is stopped, and the MCU jumps into an Interrupt Service Routine (ISR) that handles the event processing. On completion of the ISR, normal code execution is continued.

RYZ012 6. Multi-Standard Wireless Communication Module for Bluetooth 5 Low Energy and 802.15.4 I2C Interface The RYZ012 embeds an I2C hardware module, which can act as I2C Master or I2C Slave. I2C is a popular inter-IC interface requiring only 2 bus lines, a serial data line (SDA) and a serial clock line (SCL). 6.1 Communication Protocol The I2C unit supports I2C Standard Mode (100kbps) and I2C Fast Mode (400kbps) with restriction that system clock must be running at least at 10x the data rate.
PAGE 78
RYZ012 Multi-Standard Wireless Communication Module for Bluetooth 5 Low Energy and 802.15.4 In DMA Mode, the master must first write the address to be read or written into the RYZ012. The address is three bytes long, by which the MSB is transmitted first. For a write operation, the data to be written can follow the address immediately. For read access, another start byte must be transmitted with read bit set. The received address is automatically offset by 0x800000.
PAGE 79
RYZ012 6.3 Multi-Standard Wireless Communication Module for Bluetooth 5 Low Energy and 802.15.4 Master Mode In Master Mode, the RYZ012 must provide the clock for I2C transfers. The clock speed is configured in register I2C:CPRE. The resulting I2C clock frequency is FI2C =FSYS /(4*I2C:CPRE). I2C master transfers are configured in register I2C:CYCTRL. The single bits in this register allow inclusion or exclusion of certain stages of an I2C transfer. Register I2C:MST carries master status information. 6.3.

RYZ012 7. Multi-Standard Wireless Communication Module for Bluetooth 5 Low Energy and 802.15.4 SPI Interface The RYZ012 embeds a Serial Peripheral Interface (SPI)that can act as master or slave. SPI is a high-speed, full-duplex synchronous communication bus requiring four bus lines including a chip select (CS) line, a data input (DI) line, a data output (DO) line and a clock (CK) line. The bits CPOL and CPHA in register SPI:MODE control SPI clock polarity and phase.
PAGE 86
RYZ012 7.2 Multi-Standard Wireless Communication Module for Bluetooth 5 Low Energy and 802.15.4 SPI Slave Mode Slave Mode SPI transfers must follow a communication scheme similar to I2C DMA mode. For each transfer, the master first sends four bytes of data. First it determines the memory address to be read or written; next a command byte, controlling read or write is sent. The address consists of three bytes AddrH, AddrM and AddrL. The address is offset by 0x800000 automatically by the SPI hardware.

RYZ012 Multi-Standard Wireless Communication Module for Bluetooth 5 Low Energy and 802.15.4 11. PWM The RYZ012 has six Pulse-Width-Modulation (PWM) channels. Each PWM has separate direct (non-inverted) outputs named PWMx. In addition, for channels 0-2 and 4, inverted outputs named PWMxN are available. The PWM clock derives from the system clock. PWM:CLKDIV serves as frequency divider for the PWM clock, such that FPWM =FSYS /(PWM:CLKDIV+1).

RYZ012 Multi-Standard Wireless Communication Module for Bluetooth 5 Low Energy and 802.15.4 After completion of a signal frame, the corresponding PWM cycle done interrupt flag PWM:INT0:FRx is set. If the interrupt is enabled in register PWM:MASK0, an interrupt request is sent to the interrupt controller. The user needs to write 1b'1 to the flag bit to manually clear it. 11.1.2 Counting Mode Only PWM0 supports Counting mode. PWM:MODE:MODE should be set as 4b'0001 to select PWM0 counting mode.

RYZ012 21.3.2.1 Multi-Standard Wireless Communication Module for Bluetooth 5 Low Energy and 802.15.4 Antenna Trace Design The antanna trace connecting the modules RF pad with the antenna connector must be designed to have 50 Ohms impedance. The impedance of the trace depends on different parameters such as the dielectric constant, trace width and height and distances to ground planes. The integrator should use a calculator such as AWR TXLine to compute the exact geometry of the antenna trace.

RYZ012 Multi-Standard Wireless Communication Module for Bluetooth 5 Low Energy and 802.15.4 Important Notice: If the antenna is not fixed to the device, the antenna connector must be unique (non-standard). One type of antenna connector that fulfils this requirement is the Reverse SMA connector. 21.4.2.2 RED (Europe) Any design should undergo radiated RF measurements, regardless of the antenna being used (including the original antenna noted in section 21.4.2).

Soldering Information The recommended soldering profile for a lead-free (RoHS-compliant) process is shown below. Figure 40. Recommended Soldering Profile It is important to ensure this temperature profile is measured at the sensor itself. Measuring the profile at a larger component with a higher thermal mass results in the temperature at the small sensor measuring higher than expected.
