Freescale Semiconductor (NYSE:FSL) (NYSE:FSL.B) is
bringing enhanced system integrity and higher integration to designers
of automotive body and multiplexing applications by extending its
high-performance S12X 16-bit microcontroller (MCU) range. With more
memory options, the advanced S12XE MCU family was designed to provide
greater functionality in one package and reduce overall system costs.
The lead device, S12XEP100, doubles the memory size at the top of
the S12X range to 1MB and significantly increases MCU performance for
applications including central body control, instrumentation, door
modules and chassis nodes. The advanced 208 MAP BGA package option
delivers many more input/output ports than previously available.
Based on the popular HCS12 product line, the S12XE's advanced
features are designed to enable current HCS12 users to retain the
value of their investment in software and systems design, while
providing the leap in functionality required by the next generation of
vehicle electronics systems. With 16K to 1MB flash, the S12X MCU
memory range is one of the broadest on the market. The S12XE family's
leading-edge 0.18 micron process technology allows larger memory areas
and more peripheral modules to fit on smaller die sizes.
The S12XE family includes a memory protection unit (MPU), which
guards against systematic errors in software. The MPU tackles the
potential problems of different modules incorrectly interacting with
each other. This feature is crucial in automotive design as it helps
to minimize the spreading of system failures within the automobile.
"System integrity in the product range reaches new levels with the
introduction of self-correcting flash memory and a new MPU," said
Kevin Klein of Freescale's Microcontroller Division. "The MPU is a
particularly sought-after feature for today's market, where it is
increasingly common for MCU software modules to be supplied by
multiple vendors."
The S12XE family features the performance-boosting XGATE
co-processor module which has become an indispensable component in
many automotive S12X projects, providing such functions as display
driving, sophisticated pulse with modulation (PWM) capability and
interrupt handling. The XGATE significantly offloads the CPU, allowing
it to focus on critical system activities and resulting in improved
response time. The versatility of the XGATE enables manufacturers to
add more innovative features to their designs.
MC9S12XE features:
-- 1MB of flash memory with error correction code (ECC)
-- 50MHz S12X enhanced CPU
-- XGATE module
-- 64 KB of RAM, 4 KB of EEPROM (capable of 1 million cycles)
-- 5x CAN, 8x LIN, 3x SPI, 2x IIC communication interfaces
-- Advanced interrupt features
-- 32 channels of 12-bit analog-to-digital converters and
eight-channel PWM
-- Eight-channel timer with prescalers; four 16-bit internal
counters
-- Non-multiplexed external bus interface option
-- On-chip single wire debug module (BDM) with trace buffer
-- 208-, 144-, 112- and 80-pin versions qualified from -40 to
+125 degrees Celsius
Speeding system development
Third-party hardware and software tools are available from
multiple vendors. Designers can also use existing HCS12 tools for
S12XE development.
In addition to demonstration and development tools, Freescale
offers comprehensive technical support, including reference designs,
application notes and online tutorials, all of which are designed to
reduce development time. Additional design information and software
are available on the Freescale Web site,
www.freescale.com/files/pr/s12xe.html.
Product Availability
Freescale Semiconductor offers a full range of S12X devices with
various quantities of flash and application-specific functionality.
The one-megabyte S12XEP100 device is sampling now and allows up to 100
percent emulation of the whole S12XE family, down to 128K. An array of
development tools including evaluation boards and C-compilers is also
expected to be available later this month.
