INTRODUCTION:
Atmel’s ATSAM3S4BA-AU is a member of a series of Flash microcontrollers based on the high performance 32-bit ARM Cortex-M3 RISC processor. It operates at a maximum speed of 64 MHz and features a 256 Kbyte Flash and a 48 Kbyte
SRAM, Full Speed USB Device port with embedded transceiver, an External Bus
Interface featuring a Static Memory Controller providing connection to SRAM,
PSRAM, NOR Flash and NAND Flash, 2x USARTs, 2x UARTs, 2x TWIs, 3x SPI, an
I2S, as well as 1 PWM timer, 6x general-purpose 16-bit timers, an RTC, an ADC, a
12-bit DAC and an analog comparator.

SCHEMATIC:
BOARD LAYOUT:
Page 8
POWER SUPPLY CIRCUIT:
SAM3-H256 is typically power supplied with +5 V from USB, but it also can be
power supplied with +5VDC via extension connector (signal VIN from EXT2
connector pin17).
The programmed board power consumption is about 50 mA.
RESET CIRCUIT:
SAM3-H256 reset circuit includes U1 (MCP130T), R12 (10k), JTAG
connector pin 15, EXT2 pin 20, ATSAM3S4BA-AU pin 39 (NRST) and RESET
button.
CLOCK CIRCUIT:
Quartz crystal Q1 12.000 MHz is connected to ATSAM3S4BA-AU pin 61
(PB8/XOUT) and pin 62 (PB9/XIN).
JUMPER DESCRIPTION:
L_E
This jumper, when closed, enables status led – STAT.
Default state is closed.
TEST
This jumper, when closed, connects ATSAM3S4BA-AU pin 40 (TST) to 3.3V. The TST
pin is used for JTAG Boundary Scan Manufacturing Test or Fast Flash programming
mode.
When TEST jumper is opened – normal mode is enabled.
Default state is opened.

Description for programming via USB port using SAM-BA software
The ATSAM3S4BA-AU can be programmed via USB using the SAM-BATM software. Before
being able to use SAM-BA, a recovery procedure, which consists of copying the SAM-BA Boot
Assistant into Flash must be performed as follows:
1. Disconnect board from USB
2. Connect PB12 to 3.3V
3. Power up the board
4. Wait 10s
5. Power down the board
6. Remove the connection between PB12 and 3.3V
7. Power up the board via USB
8. If SAM-BA USB driver are installed you can use SAM-BA tool
INPUT/OUTPUT:
Status Led (green) with name STAT connected via jumper L_E to ATSAM3S4BAAU pin 31 (PA8/CTS0/ADTRG/WKUP5/XOUT32).
Power-on LED (red) with name PWR – this LED shows that +3.3V is applied to the
board.
Reset button with name RESET connected to ATSAM3S4BA-AU pin 39 (NRST).
Page 10
EXTERNAL CONNECTORS DESCRIPTION:
JTAG:
The JTAG connector allows the software debugger to talk via a JTAG (Joint Test Action
Group) port directly to the core. Instructions may be inserted and executed by the core thus allowing
ATSAM3S4BA-AU memory to be programmed with code and executed step by step by the host
software.
For more details refer to IEEE Standard 1149.1 - 1990 Standard Test Access Port and Boundary
Scan Architecture and ATSAM3S4BA-AU datasheets and users manual.
