Description
The STR750 family of 32-bit microcontrollers combines the industry-standard ARM7TDMI®
32-bit RISC core, featuring high performance, very low power, and very dense code, with a
comprehensive set of peripherals and ST's latest 0.18µ embedded Flash technology. The
STR750 family comprises a range of devices integrating a common set of peripherals as
well as USB, CAN and some key innovations like clock failure detection and an advanced
motor control timer. It supports both 3.3V and 5V, and it is also available in an extended
temperature range (-40 to +105°C). This makes it a genuine general purpose
microcontroller family, suitable for a wide range of applications:
●

3.1
Functional description
The STR750F family includes devices in 2 package sizes: 64-pin and 100-pin. Both types
have the following common features:
ARM7TDMI-S
TM
core with embedded Flash & RAM
STR750F family has an embedded ARM core and is therefore compatible with all ARM tools
and software. It combines the high performance ARM7TDMI-S
TM
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.
Figure 1
shows the general block diagram of the device family.
Embedded Flash memory
Up to 256 KBytes of embedded Flash is available in Bank 0 for storing programs and data.
An additional Bank 1 provides 16 Kbytes of RWW (Read While Write) memory allowing it to
be erased/programmed on-the-fly. This partitioning feature is ideal for storing application
parameters.
●
When configured in burst mode, access to Flash memory is performed at CPU clock
speed with 0 wait states for sequential accesses and 1 wait state for random access
(maximum 60 MHz).
When not configured in burst mode, access to Flash memory is performed at CPU
clock speed with 0 wait states (maximum 32 MHz)
●
Embedded SRAM
16 Kbytes of embedded SRAM accessed (read/write) at CPU clock speed with 0 wait states.
Enhanced interrupt controller (EIC)
In addition to the standard ARM interrupt controller, the STR750F embeds a nested interrupt
controller able to handle up to 32 vectors and 16 priority levels. This additional hardware
block provides flexible interrupt management features with minimal interrupt latency.
