Lower-cost devices and new memory variants of
the successful 32-bit embedded Flash MCUs will meet the requirements of
a broader range of emerging applications
 Geneva,
May 12, 2005 – STMicroelectronics (NYSE: STM) – a
leader in 8-bit microcontrollers and fast growing in 32-bit MCUs –
today announced new devices in its powerful and highly integrated 32-bit
ARM-based STR710F microcontroller
series, which will extend this successful family to high-performance,
cost-sensitive applications needing fewer on-chip facilities and to embedded
systems that will benefit from increased on-chip RAM. The new MCUs will
reduce costs, allow greater design flexibility, and enable manufacturers
to produce a range of STR7-based products at different performance levels.
For applications that require the performance and flexibility of an STR7
microcontroller but have a limited amount of program code, ST is introducing
lower-cost 64-kbyte Flash versions of both the USB (STR711)
and the CAN interface (STR712) devices – alongside the established
versions which have either 128 or 256 kbytes of Flash program memory.
Both of the new devices retain the 16-kbyte data-Flash memory of other
family members and include 16 kbytes of RAM. They are available in a 64-pin
TQFP64 package. Other cost-sensitive applications that don’t
need either USB or CAN interfaces can now utilize the new STR715, a
lower-cost ‘naked’ MCU with 64 kbytes of code Flash memory,
16 kbytes of data Flash and 16 kbytes of RAM, but with no USB or CAN
module. This cost-optimized 32-bit MCU is available in a TQFP64 package
and specifically addresses small-footprint, low-cost applications such
as industrial systems and consumer appliances that need a versatile
and high-performance processor, but not USB or CAN.
ST has now doubled the on-chip RAM of all of the mid-range, 128-kbyte
Flash versions in the STR710F family from 16 to 32 kbytes, optimizing
the RAM/Flash balance of these devices, minimizing any memory constraints
during code development, and opening up new possibilities for more complex
applications. The memory choices in the family are now 256 kbytes of
code Flash with 64 kbytes of RAM, 128 kbytes of Flash with 32 kbytes
of RAM, and 64 kbytes of Flash with 16 kbytes of RAM; all devices include
16 kbytes of data Flash memory.
 The
STR710F family – based on the industry-standard ARM7TDMI 32-bit
RISC CPU – is ideal for embedded systems requiring a compact but
powerful MCU, and for scalable solutions such as user interfaces, factory-automation
systems and point-of-sale (POS) applications. It offers best-in-class
random access time to Flash memory – up to 33MHz direct from Flash
and up to 50MHz, with zero-wait states for sequential code, using burst
acceleration – and is therefore optimized for real-time applications.
The family offers up to ten communications interfaces, including CAN,
USB, HDLC (High-Level Data Link Control), MMC (Multimedia Card), and
a smart-card interface.
Flexible package options include the compact, low-pin-count TQFP64,
and a 144-pin TQFP144 with external memory bus. A choice of cost-effective,
state-of-the-art hardware and software development tools includes an
ARM RealView Developer Kit targeted specifically at ST’s STR7
family.
All of the new MCUs are available now in sample quantities, and will
enter volume production by the end of Q2 2005. Pricing is approximately
$5.50 in quantities of 10,000 for the STR711 and STR712 members of the
family; and approximately $4.60, also in quantities of 10,000, for the
STR715.
