Overview
ARM‚ core with embedded Flash & RAM
STR73xF family combines the high performance ARM7TDMI™ CPU with an extensive range
of peripheral functions and enhanced I/O capabilities. All devices have on-chip high-speed
single voltage FLASH memory and high-speed RAM. The STR73xF family has an
embedded ARM core and is therefore compatible with all ARM tools and software.
Extensive tools support
STMicroelectronics’ 32-bit, ARM core-based microcontrollers are supported by a complete
range of high-end and low-cost development tools to meet the needs of application
developers. This extensive line of hardware/software tools includes starter kits and complete
development packages all tailored for ST’s ARM core-based MCUs.
The range of development packages includes third-party solutions that come complete with
a graphical development environment and an in-circuit emulator/programmer featuring a
JTAG application interface. These support a range of embedded operating systems (OS),
while several royalty-free OSs are also available.
For more information, please refer to ST MCU site http://www.st.com/mcu
Figure 1 shows the general block diagram of the device family.
Package Choice: Reduced Pin-Count TQFP100 or Feature-Rich 144-pin TQFP or
LFBGA
The STR73xF family is available in 3 packages. The TQFP144 and LFBGA144 versions
have the full set of all features. The 100-pin version has fewer timers, I/Os and ADC
channels. Refer to the Device Summary on Page 1 for a comparison of the I/Os available on
each package.
The family includes versions with and without CAN.

STR73xF
Introduction
High Speed Flash Memory
The Flash program memory is organized in 32-bit wide memory cells which can be used for
storing both code and data constants. It is accessed by CPU with zero wait states @ 36
MHz.
The STR7 embedded Flash memory can be programmed using In-Circuit Programming or
In-Application programming.
The Flash memory endurance is 10K write/erase cycles and the data retention is 20 years
@ 85° C.
IAP (In-Application Programming): The IAP is the ability to re-program the Flash memory
of a microcontroller while the user program is running.
ICP (In-Circuit Programming): The ICP is the ability to program the Flash memory of a
microcontroller using JTAG protocol while the device is mounted on the user application
board.
The Flash memory can be protected against different types of unwanted access
(read/write/erase). There are two types of protection:
●
Sector Write Protection
●
Flash Debug Protection (locks JTAG access)
Flexible Power Management
To minimize power consumption, you can program the STR73xF to switch to SLOW, WFI
LPWFI, STOP or HALT modes depending on the current system activity in the application.
Flexible Clock Control
Two clock sources are used to drive the microcontroller, a main clock driven by an external
crystal or ceramic resonator and an internal backup RC oscillator that operates at 2MHz or
32 kHz. The embedded PLL can be configured to generate an internal system clock of up to
36 MHz. The PLL output frequency can be programmed using a wide selection of multipliers
and dividers.
Voltage Regulators
The STR73xF requires an external 4.5 to 5.5V power supply. There are two internal Voltage
Regulators for generating the 1.8V power supply needed by the core and peripherals. The
main VR is switched off and the Low Power VR switched on when the application puts the
STR73xF in Low Power Wait for Interrupt (LPWFI) mode.
Low Voltage Detectors
The voltage regulator and Flash modules each have an embedded LVD that monitors the
internal 1.8V supply. If the voltage drops below a certain threshold, the LVD will reset the
STR73xF.
Note: An external power-on reset must be provided ensure the microcontroller starts-up
correctly.

STR73xF
On-Chip Peripherals
CAN Interfaces
The three CAN modules are compliant with the CAN specification V2.0 part B (active). The
bit rate can be programmed up to 1 MBaud. These are not available in the STR735 and
STR736.
DMA
4 DMA controllers, each with 4 data streams manage memory to memory, peripheral to
peripheral, peripheral to memory and memory to peripheral transfers. The DMA requests
are connected to TIM timers, BSPI0, BSPI1, BSPI2 and ADC. One of the streams can be
configured to be triggered by a software request, independently from any peripheral activity.
16-bit Timers (TIM)
Each of the ten timers (six in 100-pin devices) have a 16-bit free-running counter with 7-bit
prescaler, up to two input capture/output compare functions, a pulse counter function, and a
PWM channel with selectable frequency. This provides a total of 16 independent PWMs (12
in 100-pin devices) when added with the PWM modules (see next paragraph).
PWM Modules (PWM)
The six 16-bit PWM modules have independently programmable periods and duty-cycles,
with 5+3 bit prescaler factor.
Timebase Timers (TB)
The three 16-bit Timebase Timers with 8-bit prescaler for general purpose time triggering
operations.
Realtime Clock (RTC)
The RTC provides a set of continuously running counters driven by separate clock signal
derived from the main oscillator. The RTC can be used as a general timebase or
clock/calendar/alarm function. When the STR73xF is in LPWFI mode the RTC keeps
running, powered by the low power voltage regulator.
UARTs
The 4 UARTs allow full duplex, asynchronous, communications with external devices with
independently programmable TX and RX baud rates up to 625K baud.
Buffered Serial Peripheral Interfaces (BSPI)
Each of the three BSPIs allow full duplex, synchronous communications with external
devices, master or slave communication at up 6 Mb/s (@36 MHz System Clock).
I2C Interfaces
The two I2C Interfaces provide multi-master and slave functions, support normal and fast
I2C mode (400 kHz) and 7 or 10-bit addressing modes.
A/D Converter
The 10-bit Analog to Digital Converter, converts up to 16 channels in single-shot or
continuous conversion modes (12 channels in 100-pin devices). The minimum conversion
time is 3us.

Introduction
Watchdog
The 16-bit Watchdog Timer protects the application against hardware or software failures
and ensures recovery by generating a reset.
I/O Ports
Up to 112 I/O ports (72 in 100-pin devices) are programmable as general purpose
input/output or Alternate Function.
External Interrupts and Wake-Up Lines
16 external interrupts lines are available for application use. In addition, up to 32 external
Wakeup lines (18 in 100-pin devices) can be used as general purpose interrupts or to wakeup the application from STOP mode.

Legend / Abbreviations for Table 3:
Type:
I = input, O = output, S = supply, HiZ= high impedance,
In/Output level:
TT= TTL 0.8V / 2V with input trigger
CT= CMOS 0.3VDD/0.7VDD with input trigger
Port and control configuration:
Input:
pu/pd = with internal 100kΩ weak pull-up or pull down
Output:
OD = open drain (logic level)
PP = push-pull
Interrupts:
INTx =external interrupt line
WUPx =Wake-Up interrupt line
The reset state (during and just after the reset) of the I/O ports is input floating (Input Tristate
TTL mode). To avoid excess power consumption, unused I/O ports must be tied to ground.

Memory Mapping
Figure 5 shows the various memory configurations of the STR73xF system. The system
memory map (from 0x0000_0000 to 0xFFFF_FFFF) is shown on the left part of the figure,
the right part shows maps of the Flash and APB areas. For flexibility the Flash or RAM
addresses can be aliased to Block 0 addresses using the remapping feature
Most reserved memory spaces (gray shaded areas in Figure 5) are protected from access
by the user code. When an access this memory space is attempted, an ABORT signal is
generated. Depending on the type of access, the ARM processor will enter “prefetch abort”
state (Exception vector 0x0000_000C) or “data abort” state (Exception vector
0x0000_0010). It is up to the application software to manage these abort exceptions.

3.1
Parameter conditions
Unless otherwise specified, all voltages are referred to VSS.
3.1.1
Minimum and maximum values
Unless otherwise specified the minimum and maximum values are guaranteed in the worst
conditions of ambient temperature, supply voltage and frequencies by tests in production on
100% of the devices with an ambient temperature at TA=25°C and TA=TAmax (given by the
selected temperature range).
Data based on characterization results, design simulation and/or technology characteristics
are indicated in the table footnotes and are not tested in production. Based on
characterization, the minimum and maximum values refer to sample tests and represent the
mean value plus or minus three times the standard deviation (mean±3Σ).
3.1.2
Typical values
Unless otherwise specified, typical data are based on TA=25°C and VDD=5V. They are given
only as design guidelines and are not tested.
Typical ADC accuracy values are determined by characterization of a batch of samples from
a standard diffusion lot over the full temperature range, where 95% of the devices have an
error less than or equal to the value indicated (mean±2Σ).
3.1.3
Typical curves
Unless otherwise specified, all typical curves are given only as design guidelines and are
not tested.

1. All 5V power (VDD, VDDA) and ground (VSS, VSSA) pins must always be connected to the external 5V
supply
2. IINJ(PIN) must never be exceeded. This is implicitly insured if VIN maximum is respected. If VIN maximum
cannot be respected, the injection current must be limited externally to the IINJ(PIN) value. A positive
injection is induced by VIN>VDD while a negative injection is induced by VIN<VSS.
3. Negative injection disturbs the analog performance of the device. See note in Section 3.3.6: 10-bit ADC
characteristics on page 44.
4. When several inputs are submitted to a current injection, the maximum ΣIINJ(PIN) is the absolute sum of the
positive and negative injected currents (instantaneous values). These results are based on
characterization with ΣIINJ(PIN) maximum current injection on four I/O port pins of the device.
5.) In 144-pin devices, only +10mA on P0.3, P1.13, P3.6 and P4.13 pins (negative injection not allowed).

2. Data based on characterization results, tested in production at VDD max. and TA = 25°C.
3. I/O in static configuration (not toggling). RUN mode is almost independent of temperature. On the
contrary RUN mode current is highly dependent on the application. The IDDRUN value can be
significantly reduced by the application in the following ways: switch-off unused peripherals (default),
reduce peripheral frequency through internal prescaler, fetch the most frequently-used functions from RAM
and use low power mode when possible.

2) For test or boot purpose, XTAL2 can be used as an high impedance input pin to provide an external
clock to the device. XTAL1 should be grounded, and XTAL2 connected to a wave signal generator
providing a 0 to VDD signal. Directly driving XTAL2 may results in deteriorated jitter and duty cycle.

EMC characteristics
Susceptibility tests are performed on a sample basis during product characterization.
Functional EMS (Electro Magnetic Susceptibility)
Based on a simple running application on the product (toggling 2 LEDs through I/O ports),
the product is stressed by two electro magnetic events until a failure occurs (indicated by the
LEDs).
●
ESD: Electro-Static Discharge (positive and negative) is applied on all pins of the
device until a functional disturbance occurs. This test conforms with the IEC 1000-4-2
standard.
●
FTB: A Burst of Fast Transient voltage (positive and negative) is applied to VDD and
VSS through a 100pF capacitor, until a functional disturbance occurs. This test
conforms with the IEC 1000-4-4 standard.
A device reset allows normal operations to be resumed. The test results are given in the
table below based on the EMS levels and classes defined in application note AN1709.
Designing hardened software to avoid noise problems
EMC characterization and optimization are performed at component level with a typical
application environment and simplified MCU software. It should be noted that good EMC
performance is highly dependent on the user application and the software in particular.
Therefore it is recommended that the user applies EMC software optimization and
prequalification tests in relation with the EMC level requested for his application.
Software recommendations:
The software flowchart must include the management of runaway conditions such as:
●
Corrupted program counter
●
Unexpected reset
●
Critical Data corruption (control registers...)
Prequalification trials:
Most of the common failures (unexpected reset and program counter corruption) can be
reproduced by manually forcing a low state on the RESET pin or the Oscillator pins for 1
second.
To complete these trials, ESD stress can be applied directly on the device, over the range of
specification values. When unexpected behavior is detected, the software can be hardened
to prevent unrecoverable errors occurring (see application note AN1015).

Electro Magnetic Interference (EMI)
Based on a simple application running on the product (toggling 2 LEDs through the I/O

Absolute Maximum Ratings (Electrical Sensitivity)
Based on three different tests (ESD, LU and DLU) using specific measurement methods, the
product is stressed in order to determine its performance in terms of electrical sensitivity.
For more details, refer to the application note AN1181.
Electro-Static Discharge (ESD)
Electro-Static Discharges (a positive then a negative pulse separated by 1 second) are
applied to the pins of each sample according to each pin combination. The sample size
depends on the number of supply pins in the device (3 parts*(n+1) supply pin). Two models
can be simulated: Human Body Model and Machine Model. This test conforms to the
JESD22-A114A/A115A standard.

Static and Dynamic Latch-Up
●
LU: 3 complementary static tests are required on 10 parts to assess the latch-up
performance. A supply overvoltage (applied to each power supply pin) and a current
injection (applied to each input, output and configurable I/O pin) are performed on each
37/53

sample. This test conforms to the EIA/JESD 78 IC latch-up standard. For more details,
refer to the application note AN1181.
●
DLU: Electro-Static Discharges (one positive then one negative test) are applied to
each pin of 3 samples when the micro is running to assess the latch-up performance in
dynamic mode. Power supplies are set to the typical values, the oscillator is connected
as near as possible to the pins of the micro and the component is put in reset mode.
This test conforms to the IEC1000-4-2 and SAEJ1752/3 standards. For more details,
refer to the application note AN1181.

3. During the sample time the input capacitance CAIN (6.8 max) can be charged/discharged by the external
source. The internal resistance of the analog source must allow the capacitance to reach its final voltage
level within tS. After the end of the sample time tS, changes of the analog input voltage have no effect on
the conversion result. Values for the sample clock tS depend on programming.

1. ADC Accuracy vs. Negative Injection Current: Injecting negative current on any of the standard (nonrobust) analog input pins should be avoided as this significantly reduces the accuracy of the conversion
being performed on another analog input. It is recommended to add a Schottky diode (pin to ground) to
standard analog pins which may potentially inject negative current. The effect of negative injection current

Analog Power Supply and Reference Pins
The VDDA and VSSA pins are the analog power supply of the A/D converter cell. They act as
the high and low reference voltages for the conversion.
Separation of the digital and analog power pins allow board designers to improve A/D
performance. Conversion accuracy can be impacted by voltage drops and noise in the event
of heavily loaded or badly decoupled power supply lines (see: General PCB Design
Guidelines).
General PCB Design Guidelines
To obtain best results, some general design and layout rules should be followed when
designing the application PCB to shield the noise-sensitive, analog physical interface from
noise-generating CMOS logic signals.
●
Use separate digital and analog planes. The analog ground plane should be connected
to the digital ground plane via a single point on the PCB.
●
Filter power to the analog power planes. It is recommended to connect capacitors, with
good high frequency characteristics, between the power and ground lines, placing
0.1µF and optionally, if needed 10pF capacitors as close as possible to the STR7
power supply pins and a 1 to 10µF capacitor close to the power source (see Figure 23).
●
The analog and digital power supplies should be connected in a star network. Do not
use a resistor, as VDDA is used as a reference voltage by the A/D converter and any
resistance would cause a voltage drop and a loss of accuracy.
●
Properly place components and route the signal traces on the PCB to shield the analog
inputs. Analog signals paths should run over the analog ground plane and be as short
as possible. Isolate analog signals from digital signals that may switch while the analog
inputs are being sampled by the A/D converter. Do not toggle digital outputs near the
A/D input being converted.
Software Filtering of Spurious Conversion Results
For EMC performance reasons, it is recommended to filter A/D conversion outliers using
software filtering techniques.

Package characteristics
Thermal characteristics
The average chip-junction temperature, TJ, in degrees Celsius, may be calculated using the
following equation:
TJ = TA + (PD x ΘJA)
(1)
Where:
–
TA is the Ambient Temperature in °C,
–
ΘJA is the Package Junction-to-Ambient Thermal Resistance, in °C/W,
–
PD is the sum of PINT and PI/O (PD = PINT + PI/O),
–
PINT is the product of IDD and VDD, expressed in Watt. This is the Chip Internal
Power,
–
PI/O represents the Power Dissipation on Input and Output Pins; User Determined.
Most of the time for the applications PI/O < PINT and may be neglected. On the other hand,
PI/O may be significant if the device is configured to drive continuously external modules
and/or memories.
An approximate relationship between PD and TJ (if PI/O is neglected) is given by:
PD = K / (TJ + 273°C)
(2)
Therefore (solving equations 1 and 2):
K = PD x (TA + 273°C) + ΘJA x PD2
(3)
Where:
–
K is a constant for the particular part, which may be determined from equation (3)
by measuring PD (at equilibrium) for a known TA. Using this value of K, the values
of PD and TJ may be obtained by solving equations (1) and (2) iteratively for any
value of TA

Known limitations
6.1
Low Power Wait For Interrupt mode
When the STR73x device is put in Low Power Wait For Interrupt mode (LPWFI), the Flash
goes into Low Power mode or Power Down mode, depending on the setting of the PWD bit
in the Flash Control Register 0 (default is ‘0’, Low Power mode). This default mode can
create excessive voltage conditions on the transistor gates and may affect the long term
behavior of the Low Power mode circuitry.
Workaround
There is no workaround. If Low Power Wait For Interrupt mode is used, it is strongly
suggested to configure the Flash to enter Power Down mode (bit PWD = ‘1’).
6.2
PLL free running mode at high temperature
When the STR73x device is operated and an ambient temperature (TA) of more than 55°C
and the main system clock (fMCLK) is sourced by the PLL in free running mode, the device
may not work properly.
Workaround
At high temperature (more than 55°C), it is recommended to use the internal RC oscillator
as a backup clock source rather than the PLL free running mode.
