SAN JOSE, Calif. — November 3, 2009 — Renesas
Technology America, Inc., today announced the release of a total of
eight versions of the SH7266 and SH7267, two new high-performance
32-bit MCU products with an on-chip SRAM size of 1.5 MB, that are
intended for embedded applications in the industrial and consumer
fields such as displays for digital audio players or graphical
dashboards. Sample shipments will begin in February 2010 in
Japan.
The SH7266 and SH7267 are the enhanced products of the SH7260
Series that belongs to the SuperHTM*1 Family of
high-performance 32-bit RISC MCUs. They each have 1.5 MB of
large-capacity on-chip SRAM, an increase of 50% from the 1 MB of
earlier MCUs in the SH7260 Series, to take the place of external
synchronous DRAM (SDRAM). This makes it possible to implement a VGA
display (640 × 480 pixels) without the need for external
SDRAM. The large-capacity SRAM can be used as a display frame
buffer or as a work area for storing programs or data.
The SH7266 is available in a 144-pin QFP package and the SH7267
in a 176-pin QFP package. Their main features are described
below.

Large-capacity (1.5 MB) on-chip SRAM that eliminates the need
for external SDRAM
The SH7266 and SH7267 each have 1.5 MB of large-capacity on-chip
SRAM that can be used in place of external SDRAM as a program or
work area. The large-capacity SRAM can also be used as a display
frame buffer for video data, eliminating the need to use external
SDRAM for the frame buffer. When used as a frame buffer, the
large-capacity SRAM can store two frames of video data in VGA
format, an increase from the WQVGA format (480 × 240 pixels)
of earlier products in the same series, which can be displayed on a
TFT LCD panel via a display controller. This contributes to
reducing overall system cost and size.

Numerous graphical display functions
The SH7266 and SH7267 provide a new video display controller and
digital video input pins for use with graphical and video display
applications. It supports functionality such as video recording,
size reduction, alpha blending effects (superimposition of
transparent or semitransparent images), and superimposition of
video input. Digital RGB output pins allow output of images or
video in RGB565 format (in which each color is represented by 16
bits: 5 bits for the red [R] component, 6 bits for green [G], and 5
bits for blue [B]) at up to VGA size.
This on-chip functionality makes it possible to develop products,
such as car information systems with rear-view or side-view camera
display and midrange or low-end graphical dashboard systems, using
fewer devices and at a lower cost.

Full complement of on-chip peripheral functions
The SH7266 and SH7267 each have a large number of on-chip
peripheral functions, including Hi-Speed USB 2.0 (host and function
modes). In addition to standard serial interfaces such as serial
communication interfaces with 16-stage FIFO and I2C bus
interfaces, the SH7266 and SH7267 are equipped with serial sound
interfaces for digital audio data I/O, a CAN*2
interface, 16-bit timers including CMT and MTU2, and PWM timers for
motor control. This array of on-chip peripheral functions provides
support for a wide range of applications. Also integrated on-chip
is a 16-bit external bus controller that enables direct connection
to flash ROM, SDRAM, or SRAM without the need for additional
external components.

< Product Background >
As embedded solutions for digital audio and display systems,
Renesas Technology has already released a variety of products for
industrial and consumer applications, as well as automotive
applications, in the SH7260 Series, which incorporates the SH2A-FPU
32-bit CPU core for superior real-time processing performance. In
recent years, an increasing number of products in categories
ranging from office equipment, such as a printer and household
appliances, to game consoles and security systems employ display
panels to show a wide variety of information, and demand for
display capabilities continues to grow. There is also demand for
functionality to display or record video signals from cameras.
Renesas Technology already developed the new SH7262 and SH7264 with
large-capacity (1 MB) SRAM to meet a wide range of requirements
while contributing to reduced overall system cost.
Today there is demand for higher display resolutions, and the
increasing complexity of systems means that more memory capacity is
needed for storing programs and for use as work space. This has led
to growing demand for MCU products with large-capacity on-chip
SRAM.
In response, Renesas Technology has increased the on-chip SRAM
capacity to 1.5 MB in the new SH7266 and SH7267.
< Product Details >
The SH7266 and SH7267 are built around the SH2A-FPU CPU core
(which incorporates an FPU), have a maximum operating frequency of
144 MHz, and deliver excellent processing performance. The
instruction set of the SH2A-FPU is backward compatible with the
SH-2A and SH-2 CPU cores, allowing developers to reuse program code
created for earlier products. In addition, ROM code efficiency has
been improved approximately 75% in comparison with the SH-2. As a
result, the object code for the same program can be compressed to
about three-quarters the previous size, conserving the memory
capacity available for storing programs.
In addition to the above, the peripheral functions have been
supplemented as follows.
- In addition to NOR flash memory, the SH7266 and SH7267 allow
connection of other external flash memory types such as NAND flash
memory and serial flash memory. The device can be booted from a
program read in from the external flash memory. These
microcontrollers are, thus, excellent solutions for systems
employing many different types of flash memory.
- Hi-Speed USB2.0 (host and function modes) is implemented
on-chip. When host mode is selected, the device can connect to and
communicate with multiple peripheral devices via a hub. Switching
between the host and function modes is easily accomplished by
register settings. The USB has a built-in USB transceiver that
supports all data transfer types defined in the USB standard.
- A CD-ROM decoder and a sampling rate converter for converting
the sampling frequency for audio data are implemented on-chip.
These functions are required by digital audio devices. Other
on-chip peripheral functions suitable for a variety of applications
include a Renesas SPDIF interface, a direct memory access
controller, and a SD memory card interface.
These many on-chip peripheral functions enable developers to
build systems delivering advanced functionality with a smaller
number of total components. This contributes to reduced overall
system cost.
The SH7266 and SH7267 are each available in four product
versions with different combinations of CAN interface and
IEBus*3 interface availability, for a total of eight
product versions. Additionally, each product version is
available with an operating temperature range of either –40
to 85°C or –20 to 85°C, resulting in a total lineup
of 16 product numbers. Customers can select the product version
that best meets their requirements.
The SH7266 comes in a lead-free 144-pin QFP package and the
SH7267 in a lead-free 176-pin QFP package. Both have an on-chip
debugging function*4 that enables real-time debugging at
the maximum operating frequency. The E10A-USB emulator, which uses
USB bus power and requires no external power supply, is available
as a development environment.
Renesas Technology supplies middleware with support for digital
audio compression standards such as MP3, WMA (Windows Media
Audio)*5, and AAC (Advanced Audio Coding). In
addition, software is available that provides support for the ISO
9660 file system used by CD-ROM drives, the FAT32 file system used
by hard disk drives, USB mass storage class drivers, and others.
The available software libraries support devices requiring storage
and communication capabilities, such as USB functionality for
digital audio devices or embedded applications.
Future SH7260 Series microcontrollers for the high-end market
will include multi-core products offering improved performance,
expanded on-chip memory, and enhanced peripheral functions such as
advanced display capabilities. Alongside these products offering
more speed, better performance, and higher functionality, Renesas
Technology will continue to respond to market demand with low-cost
products for use in low-end systems.
