STR73xF Data Brief
1 INTRODUCTION
This Data Brief provides the STR73xF feature summary, pin description and ordering
Information.
For complete information on the Mechanical and Electrical Device Characteristics please refer
to the Preliminary Datasheet.
For complete information on the STR73xF Microcontroller memory, registers and peripherals.
please refer to the STR73x Reference Manual.
For information on programming, erasing and protection of the internal Flash memory please
refer to the STR7 Flash Programming Reference Manual
For information on the ARM7TDMI core please refer to the ARM7TDMI Technical Reference
Manual.
1.1 Overview
ARMcore with embedded Flash & RAM
STR73xF family combines the high performance ARM7TDMICPU 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.

DataShee
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 Data Brief
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 at
55°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 mi-
crocontroller 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

DataShee
To minimize power consumption, you can program the STR73xF to switch to SLOW, WAIT
LPWAIT, 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 allows the internal system clock (up to 36 MHz) to be generated
from a main clock frequency of 10 MHz or less. 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 (LPWAIT) mode.
