3.1 Power supply selection
The 5 V power supply of AT-START-F413 can be provided through a USB cable (either through the
USB connector CN6 on the AT-Link-EZ or USB connector CN1 on the AT-START-F413), or
through an external 5 V power supply (E5V), or by an external 7~12 V power supply (VIN) via 5V
voltage regulator (U1) on the board. In this case, the 5 V power supply provides the 3.3 V power
required by the microcontrollers and peripherals by means of the 3.3 V voltage regulator (U2) on
the board.
The 5 V pin of J4 or J7 can also be used as an input power source. The AT-START-F413 board
must be powered by a 5 V power supply unit.
The 3.3 V pin of J4 or the VDD pin of J1 and J2 can also be directly used as 3.3 V input power
supply. AT-START-F413 board must be powered by a 3.3 V power supply unit.
Note: Unless 5 V is provided through the USB connector (CN6) on the AT-Link-EZ, the AT-Link-EZ will
not be powered by other power supply methods.
When another application board is connected to J4, the pin VIN, 5 V and 3.3 V can be used as
output power; J7 5V pin used as 5 V output power; the VDD pin of J1 and J2 used as 3.3 V output
power.
3.2 IDD
In the event of JP3 OFF (symbol IDD) and R13 OFF, it is allowed to connect an ammeter to
measure the power consumption of AT32F413RCT7.
JP3 OFF, R13 ON
AT32F413RCT77 is powered (Default setting, and JP3 plug is not mounted before shipping).
JP3 ON, R13 OFF
AT32F413RCT7 is powered.
JP3 OFF, R13 OFF
An ammeter must be connected to measure the power consumption of AT32F413RCT7 (if
there is no ammeter, the AT32F413RCT7 cannot be powered).

2021.2.2 10 Rev 1.20
3.3 Programming and debugging
3.3.1 Embedded AT-Link-EZ
The evaluation board embeds Artery AT-Link-EZ programming and debugging tool for users to
program/debug the AT32F413RCT7 on the AT-START-F413 board. AT-Link-EZ supports SWD
interface mode, SWO debug, and supports a set of virtual COM ports (VCP) to connect to the
USART1_TX/USART1_RX (PA9/PA10) of AT32F413RCT7. In this case, PA9 and PA10 of
AT32F413RCT7 will be affected by AT-Link-EZ as follows:
PA9 is weakly pulled up to high level by the VCP RX pin of AT-Link-EZ;
PA10 is strongly pulled up to high level by the VCP TX pin of AT-Link-EZ
The user can set R9 or R10 OFF, then the use of PA9 and PA10 of AT32F413RCT7 is not subject
to the above restrictions.
The SWO of AT-Link-EZ is connected to the TRACESWO (PB3) of AT32F413RCT7 through R18,
and will be set in floating state when the SWO debug is not enabled, which would not affect the use
of PB3. If you have any concerns in use, please set R18 OFF.
Please refer to AT-Link User Manual for complete details on the operations, firmware upgrade and
precautions of AT-Link-EZ.
The AT-Link-EZ PCB on the evaluation board can be separated from AT-START-F413 by bending
over along the joint. In this case, AT-START-F413 can still be connected to the CN7 of AT-Link-EZ
through CN2 (not mounted before shipping), or can be connected with another AT-Link to continue
the programming and debugging on the AT32F413RCT7.
3.3.2 20-pin ARM® standardJTAG connector
AT-START-F413 also reserves JTAG or SWD general-purpose connectors as
programming/debugging tools. If the user wants to use this interface to program and debug the
AT32F413RCT7, please separate the AT-Link-EZ from this board or set R41, R44 and R46 OFF,
and connect the CN3 (not mounted before shipping) to the programming and debugging tool.
Although Artery microcontrollers can be compatible with most third- party development tools in the
market, it is still recommended to use AT-Link series tools to experience the best debug
environment.

3.9 Connect to Bank3 of Flash memory via SPIM interface
The SPI Flash EN25QH128A on the board is connected to the AT32F413RCT7 via SPIM interface
and used as Bank 3 of expanded Flash memory.
When using the Bank 3 of the Flash memory via SPIM interface, the JP8 one-piece jumper, as
shown in Table 2, should select the left SPIM side. In this case, PB1, PA8, PB10 PB11, PB6 and
PB7 are not connected to the external LQFP64 I/O extension connector. These 6 pins are marked
by adding [*] after the pin name of extension connector on the PCB silkscreen.
