SOFTWARE DEVELOPMENT
The Anthias uses Cambridge Silicon Radio’s CSR1000™ chipset. The RISC microcontroller is
capable of running applications to access the BTLE v4.0 software stack, serial interfaces and IOs.
Software development is through CSR’s µEnergy Integrated Development Environment (xIDE)
supplied with CSR’s μEnergy™ Software Development Kits (SDKs). The SDK is available from
either CSR or Unigen for purchase. The SDK allows the module to be utilized specifically for the
end application and product.
The xIDE allows software engineers to build and configure the application projects provided with
application specific SDKs or to independently develop applications to run on CSR’s μEnergy™ ICs
or Anthias. It supports the development and debugging of applications written in ANSI C language.
Code is written in the text editor and when complete, built and compiled along with the μEnergy™
firmware supplied as part of the SDK. When compiled the resultant machine code can be
downloaded to and run on Anthias.
The code can then be debugged on-module using the facilities in xIDE. Applications can be
developed from the reference application code provided, using the example code and library
functions supplied, to adapt and add functionality. The application source code provided
implements various Bluetooth Low Energy Profiles. These Profiles can be used as part of the
user’s own applications. Using profile code and example applications as a starting point for
development, greatly reduces the effort required to produce working Bluetooth Low Energy
applications that correctly implement the required Bluetooth Low Energy Profiles
To obtain the SDK please contact Unigen for more details.
Note:
The supplied profile code usually supports all the mandatory features and most but
not all optional features of a particular profile. See the individual SDK Release Note
for details.

POWER CONTROL, REGULATION AND RESET
Figure 5: Anthias Internal Regulation Block
Internal Switch-mode Regulator
Anthias has an internal switch mode regulator that generates the main rail from the battery
(VDD_BAT). The main rail supplies the lower regulated voltage to a further internal digital linear
regulator and also to the analog sections of the Anthias module. The switch mode regulator
generates typically an internal 1.35V.
Internal Low-voltage Linear Regulator
The integrated low-voltage VDD_DIG linear regulator powers the Anthias digital circuits. The input
voltage range is 0.65V to 1.35V. It can supply programmable voltages of 0.65V to 1.20V to the
digital area of the Anthias module. The maximum output current for this regulator is 30mA.
Important Note:
These regulators are for internal Unigen use only. See example circuit diagram
for Unigen recommended circuit connection.

SERIAL INTERFACES
Application UART Interface
The Anthias UART interface provides a simple mechanism for communicating with other serial
devices using the RS232 protocol.
2 signals implement the UART function, UART_TX and UART_RX. When Anthias is connected to
another digital device, UART_RX and UART_TX transfer data between the 2 devices.
UART configuration parameters, e.g. baud rate and data format, are set using ANTHIAS
application code firmware.
When selected in firmware PIO[0] is assigned to a UART_TX output and PIO[1] is assigned to a
UART_RX input, see the module pad assignment and description for more details.
The UART CTS and UART RTS signals can be assigned to any PIO pad by the on-chip firmware.
Note: To communicate with the UART at its maximum data rate using a standard PC, the PC
requires an accelerated serial port adapter card.

SPI Master Serial Flash Interface
The SPI Serial Flash Interface is only available if Anthias is ordered and configured without the
internal EEPROM option on the module. The SPI master memory interface in the Anthias module
is overlaid on the internal I²C EEPROM interface and uses 3 other specific PIOs for the additional
signaling. See the table on the next page for more details.
PIO[2] is used to power the Serial Flash upon boot up to read the contents and load into RAM.
After loading the contents, PIO[2] is de-asserted to shut down the Serial Flash for power savings.

Programming and Debug Interface
Important Note:
The Anthias module debug SPI interface is available in SPI slave mode to enable an external
microcontroller to program and control the module, generally via libraries or tools supplied by
CSR/Unigen. The protocol of this interface is proprietary. The 4 SPI debug lines directly support
this function.
The SPI programs, configures and debugs the Anthias module. It is required for firmware upgrade
or debug. Ensure the 4 SPI signals are brought out to either test points or a header. If firmware
upgrading is required in the field then this interface needs to be accessible externally.
Take SPI_PIO#_SEL high to enable the SPI debug feature on PIO[8:5].
Anthias uses a 16-bit data and 16-bit address programming and debug interface. Transactions
occur when the internal processor is running or is stopped.
Data is written or read one word at a time, or the auto-increment feature is available for block
access.

Instruction Cycle
The ANTHIS module is the slave and receives commands on DEBUG_MOSI and outputs data on
DEBUG_MISO.
The table below shows the instruction cycle for a SPI transaction.
Table 12: SPI Transactions
1 Reset the SPI interface Hold DEBUG_CS# high for 2
DEBUG_CLK cycles
2 Write the command word Take DEBUG_CS# low and clock in the
8-bit command
3 Write the address Clock in the 16-bit address word
4 Write or read data words Clock in or out 16-bit data word(s)
5 Termination Take DEBUG_CS# high
With the exception of reset, DEBUG_CS# must be held low during the transaction. Data on
DEBUG_MOSI is clocked into the Anthias on the rising edge of the clock line DEBUG_CLK. When
reading, Anthias replies to the master on DEBUG_MISO with the data changing on the falling edge
of the DEBUG_CLK. The master provides the clock on DEBUG_CLK. The transaction is terminated
by taking DEBUG_CS# high.
The auto increment operation on the Anthias cuts down on the overhead of sending a command
word and the address of a register for each read or write, especially when large amounts of data
are to be transferred. The auto increment offers increased data transfer efficiency on the Anthias
module. To invoke auto increment, DEBUG_CS# is kept low, which auto increments the address,
while providing an extra 16 clock cycles for each extra word written or read.
Multi-slave Operation
Do not connect the Anthias module in a multi-slave arrangement by simple parallel connection of
slave MISO lines. When Anthias is deselected (DEBUG_CS# = 1), the DEBUG_MISO line does not
float. Instead, Anthias outputs 0 if the processor is running or 1 if it is stopped.

Idle Connection State as Slave
Figure 7: Idle Connection State
Treceive = 80us + (Jitter Allowance) + (Windows Widening)
Jitter Allowance = 16us
Window Widening = (Connection Interval * (Slave latency+1))*(Slave Clock Accuracy + Master
Clock Accuracy)/1e6
Radio on/off time is as important
as peak currents. Sleep clock
accuracy is vital due to window
widening between radios on/off
states.
