Tokyo, April 5, 2001--Hitachi, Ltd. (TSE: 6501) today announced the
SH7046F and SH7047F, 32-bit single-chip RISC microcontrollers, featuring
65 MIPS processing performance and 256 kbytes of on-chip 5 V single-power-supply
flash memory, for motor control devices in the white-goods, industrial,
and automotive fields. Sample shipments will begin in May 2001 in
Japan. Hitachi is also releasing mask ROM versions SH7148 and SH7049,
with sample shipments beginning in the 4th quarter of 2001 in Japan.
These products incorporate a SuperHTM
family*1 SH-2 CPU core, and as successors to the highly acclaimed
SH7040 Series for embedded applications in the consumer, OA, and industrial
fields, comprise the first phase of 0.35 um products. The finer process
provides faster CPU and peripheral module operation in a more compact
form, making it possible to improve the performance and reduce the
cost of high-precision motor control systems.
Recently, in the field of white goods such as air conditioners and
washing machines, there has been a growing demand not only for lower
prices through the integration of motor control and system control
but also for improvement on precision of controlling motors, energy-saving
design, and quieter operations. Meanwhile, in the industrial field,
including AC servos and inverters of which high performance and functionality
are required, and automotive applications such as airbags and ABS,
there is an increasing demand for more precise motor control as a
way of reducing fuel consumption and protecting the environment. The
trend in microcomputers for controlling devices is shifting to 32-bit
models from 8-bit and 16-bit models which is the current mainstream.
Hitachi has previously released 16-bit models H8/3032 Series and H8/3039
Series with an on-chip motor control timer (ITU*2) for the white goods
market, which is subject to constant pressure on price-reduction.
Hitachi has also released 32-bit SH7040 Series with an on-chip motor
control timer (MTU*3) for industrial applications which demands higher
functionality and performance. Now, Hitachi is releasing the F-ZTATTM*4
version SH7046F and SH7047F with on-chip flash memory, and the mask
ROM version SH7148 and SH7049, to further strengthen the company's
lineup of microcontrollers for motor control.
This product series features an on-chip MTU and MMT*5 as motor control
timers, enabling single-chip control of two motors that previously
required two microcontroller chips. In addition, the 65 MIPS processing
performance enables high-precision motor control and highly efficient
system control to be achieved with a single chip, making it possible
to create smaller, lower-priced systems. The two power supply systems
of previous products (5 V for the I/O ports and 3 V for the internal
logic circuitry) have been replaced by a single 5 V power supply through
the use of an on-chip step-down circuit, simplifying system construction.
With the internal logic circuits operating on a low stepped-down voltage,
both power consumption and noise have been reduced.
The SH7046F and SH7047F feature a large on-chip flash memory capacity
of 256 kbytes, while the SH7148 and SH7049 have 64 and 128 kbytes,
respectively, of on-chip mask ROM. These products are also equipped
with a comprehensive selection of peripheral functions for application
areas that demand high-precision control and integrated processing
of various kinds of control. The SH7046F and SH7148, for example,
has three A/D converter units, each comprising four channels, with
all three units capable of operating simultaneously, making it possible
to speed up the feedback control essential to high-precision motor
control. Moreover, the A/D conversion speed per unit is approximately
double that of the SH7040 Series. As a communication function, the
SH7047F and SH7049 incorporate an HCAN2*6, compatible with the CAN*7
used in in-vehicle LANs and device networks. The HCAN2 enables setting
of up to 32 message buffers in one channel, for fast and highly reliable
communication. This series also includes a module standby function
as a power-down mode that enables the clock supply to be stopped for
unnecessary modules, making it possible to implement power-down operation
according to the application.
As a development environment, the E8000S emulator can be used. The
SH7047F also incorporates H-UDI and AUD on-chip debug functions, enabling
simple emulation by using the E10A PC card emulator development tool.
The packages used are an 80-pin QFP for the SH7046F and SH7148, and
a 100-pin QFP for the SH7047F and SH7049.
Hitachi plans to further extend the product lineup in the future with
models offering even higher speed and functionality.
