Overview
This section introduces the SAM4C32-EK design. It introduces system-level concepts, such as power distribution,
memory, and interface assignments.
The Atmel SAM4C32 microcontroller is a system-on-chip solution for smart energy applications, built around two
high-performance 32-bit ARM Cortex-M4 RISC processors. These devices operate at a maximum speed of 120
MHz and feature up to 2 Mbyte of embedded Flash, 256 Kbytes of SRAM and on-chip cache for each core.
The dual ARM Cortex-M4 architecture allows for integration of application layer, communications layers and
security functions in a single device, with the ability to extend program and data memory via a 16-bit external bus
interface. The peripheral set includes an advanced cryptographic engine, two anti-tamper pins with time-stamping
function, floating point unit (FPU), five USARTs, two UARTs, two TWIs, up to seven SPIs, as well as a PWM timer,
two 3-channel general-purpose 16-bit timers, temperature compensable low-power RTC running on backup area
down to 0.5 µA, and a 50 x 6 segmented LCD controller.
The SAM4C series is a scalable platform providing, alongside Atmel's industry leading SAM4 standard
microcontrollers, unprecedented cost structure, performance and flexibility to smart meter designers worldwide.

Temperature Sensor
The Atmel AT30TS75 temperature sensor converts temperatures from -40°C to +125°C to a digital word and
provides a typical accuracy of ±0.5°C over the operating temperature range of 0°C to +85°C. The device is factory
calibrated and requires no external components to help provide a cost effective solution. To reduce current
consumption and save power, the AT30TS75 features a shutdown mode that turns off all internal circuitry except
for the internal power-on reset and serial interface circuits. In addition, the device features a power saving oneshot mode that allows the device to make a temperature measurement, update the temperature register and then
return to shutdown mode.
Device slave address byte: 0x48.

TMP0
The user can select the pull-up level for the Tamper TMP0 pin by changing the position of JP25. Selecting PB1
instead of VDDBU provides dynamic tampering synchronized with RTCOUT (PB1) pin. This position allows a
diminution of the power consumption when the button is pressed (divided by the Duty Cycle applied on RTCOUT
Output signal).
It is possible to use the TMP2 push button as an additional Tamper input. To use this feature, the user must use
JTAG in 2-wire mode (SWIO and SWD) due to the loss of the TDO pin. In this case, TMP2 is pull-up at RTCOUT
Level (PB1 pin) and can be managed dynamically synchronized with the RTCOUT pin.

Description

1
VTref 3.3V power
This is the target reference voltage. It is used to check if the target has power,
to create the logic-level reference for the input comparators, and to control the
output logic levels to the target. It is normally fed from VDD on the target board
and must not have a series resistor.
2
Vsupply 3.3V power
This pin is not connected in SAM-ICE. It is reserved for compatibility with other
equipment. Connect to VDD or leave open in target system.
3
nTRST TARGET RESET
JTAG Reset (active-low output signal that resets the target). Output from SAMICE to the Reset signal on the target JTAG port. Typically connected to nTRST
on the target CPU. This pin is normally pulled HIGH on the target to avoid
unintentional resets when there is no connection.
5
TDI TEST DATA INPUT
JTAG data input of target CPU (serial data output line, sampled on the rising
edge of the TCK signal). It is recommended that this pin is pulled to a defined
state on the target board. Typically connected to TDI on target CPU.
7
TMS TEST MODE SELECT
JTAG mode set input of target CPU. This pin should be pulled up on the target.
Typically connected to TMS on target CPU. Output signal that sequences the
target's JTAG state machine, sampled on the rising edge of the TCK signal.
9
TCK TEST CLOCK
JTAG clock signal to target CPU (output timing signal, for synchronizing test
logic and control register access). It is recommended that this pin is pulled to a
defined state on the target board. Typically connected to TCK on target CPU.
Input Return test clock signal from the target.
Some targets must synchronize the JTAG inputs to internal clocks. To assist in
meeting this requirement, a returned and retimed TCK can be used to
dynamically control the TCK rate. SAM-ICE supports adaptive clocking which
waits for TCK changes to be echoed correctly before making further changes.
Connect to RTCK if available, otherwise to GND

SAM4C32-EK Firmware Demonstration
4.1
SAM4C32-EK Default Application
The SAM4C32-EK is delivered with a preprogrammed default application in SAM4C32 Flash memory. This
application implements SAM4C32 embedded peripherals and external (on-board) peripherals as detailed in the
table below.
Table 4-1.
SAM4C32 Embedded Peripherals
Peripheral
Connected to External (on-board) Peripheral
Real-Time Clock (RTC)
—
Anti-Tamper
BP3 Push Button
Two-wire Interface
Temperature Sensor AT30TS75
Segmented LCD
Custom Atmel Display
SAM4C32 Core 1
—
10-bit ADC
Internal ADC channel connected to Battery Backup Power Rail (VDDBU)
After the first power-up without the backup battery, the time (hour and minute) of the RTC can be configured. The
Hour and Minute settings are entered using the following push buttons:
BP4 (SCROLL_UP)—sets the Hour (24H mode entries must be made)
BP5 (SCROLL_DOWN)—sets the Minute
BP6 (TMP2)—saves the Hour and Minute settings
Once the time settings have been saved, BP4 (SCROLL_UP) can be used to toggle the Hour display between 12H
or 24H mode.
Note:
RTC time configuration can be skipped by pressing BP6.
Once the hour and minute have been configured, the main application on core 0 runs in an infinite loop, repeating
the following steps:
Every second, the time is displayed with colon (:) icon blinking
Every fifteen (15) seconds, the VDDBU pin voltage is measured and displayed (1)
Every thirty (30) seconds, the temperature (using the AT30TS75) is measured and displayed in °C and in °F.
Note:
1.
On the SAM4C32-EK, the voltage measured is the VDDIO voltage minus the forward voltage of the diode in the
BAT54C (D4).
At startup, the main application configures the core 1 subsystem to run a CoreMark algorithm from the core 1
SRAM memories (SRAM1 and SRAM2). Once the CoreMark is finished, the result of the CoreMark (number of
CoreMark/MHz) is passed to the main application using the inter-processor communication embedded in the
SAM4C32. Once the result is retrieved by the main application, the result of the CoreMark is displayed and the
CoreMark algorithm running on core 1 is restarted. An ammeter connected either on JP12 (VDDIN) or on JP6
(VDDCORE) can measure the active current consumption of both cores.

Atmel-11253A-ATARM-SAM4C32-EK-UserGuide_17-Sep-14
4.2
Measuring the Backup Mode Current Consumption on VDDBU
The SAM4C32 has an ultra-low-power mode RTC and Supply controller allowing less than 1µA (typical) on
VDDBU, with the following functions/peripherals configuration:
32.768 kHz Crystal Oscillator enabled
POR backup on VDDBU disabled
RTC running
RTT enabled on 1 Hz mode
Force wake-up (FWUP) enabled
Anti-tamper Input (TMP0) enabled
To measure the current consumption on VDDBU when in backup mode, JP9 (Shutdown control) must be opened
and an ammeter connected on JP8 (VDDBU) as described in the following procedure:
1.
Power off the board using SW1
2.
Insert the 3V lithium battery provided in the battery holder
3.
Place an ammeter (with sufficient capacity to measure current lower than 1µA) on JP8
4.
Power on the board using SW1
5.
(optional) Set the RTC as described above
6.
Press the push button BP5 (SCROLL_DOWN) to place the board in low-power mode
Before shutdown, the following messages are displayed on the LCD:
“ENTERING BACKUP MODE”
“PRESS FWUP BP1 TO WAKE UP”
“USE BP3 TO GENERATE TAMPER EVENTS”
Blinking “BYE”
At this point, the current consumption on the ammeter should be less than 1µA @ 25°C @ 3V.
Once in backup mode, the anti-tamper pin 0 (TMP0) is enabled. The BP3 (TMP0) push button can be used to
generate tamper events before waking up the board. Tamper events are registered without waking up the board.
Up to 15 tamper events can be registered. To wake up the board, press BP1 (FWUP). Upon start-up, the number
of tamper events and time-stamping of the tamper events are displayed on the LCD.
