Introduction
STR73xF
4/40
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
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.
