Renesas Releases 36 New SuperH Flash Microcontrollers: the SH7216 Group 32-bit On-Chip Flash Memory Microcontrollers for Industrial Applications, Featuring 200 MHz Operation, Floating Point Unit, and Ethernet
The SH7216 group of 32-bit flash microcontrollers features 200MHz superscalar core and connectivity peripherals such as CAN, USB and Ethernet to enhance advanced motor control and real-time networked applications.
SAN JOSE, Calif. — April 7, 2009 — Renesas Technology America, Inc., today announced the release of the SH7216 group of 32-bit on-chip flash memory microcontrollers (flash microcontrollers), the newest addition to the popular 32-bit SuperH RISC family*1. It features 200 MHz operation and an extensive set of built-in peripheral and communication functions for industrial applications such as AC servos, FA (factory automation) equipment, building automation (air conditioner, electric power monitoring equipment) and various types of communication apparatus. The SH7216 group consists of 36 devices in 12 product groups that differ in on-chip memory capacity, package type, and whether or not FPU (floating point processing unit) and/or Ethernet functions are included.
The main features of these products are as follows.
Improved real-time control performance with the industry’s fastest-level 200MHz flash microcontroller
These products employ a 32-bit SH-2A superscalar core and the industry’s fastest-level 100MHz flash memory technology. Select devices also include 400MFLOPS single and double precision floating point unit. In addition, the SH7216 group implements advanced prefetch and cache techniques to deliver up to 400DMIPS of performance while executing from flash, and 480DMIPS while executing from RAM. These products also include 15 dedicated register banks to shorten the interrupt latency to just 6 cycles.
The SH7216 group provides a level of performance and precision to motor control and other factory automation applications that was traditionally achieved by using ASIC or a dedicated /DSP coprocessor.
Extensive set of peripheral and communication functions
In addition to the typical serial communication functions, these microcontrollers also feature a diverse set of interfaces, including Ethernet, CAN*2, and USB 2.0, full speed. These features eliminate the need for external communication controllers in applications such as office automation equipment, and various types of communication apparatus.
Optimal functions for industrial equipment
These microcontrollers provide two advanced motor control timer units (MTU2 and MTU2S) that can control two motors simultaneously and enable multi-axis servo control with high precision. They also provide 12-bit A/D converters that can perform conversions in 1 µs to improve precision and accuracy in motor control and other applications. Furthermore, these microcontrollers provide an extensive set of other peripheral functions, including data flash for non-volatile data storage and data transfer controller and DMAC to reduce the CPU load. This data flash memory incorporates background operation (BGO) functionality that enables data to be written at the same time a program is executing and allows data writes without slower program execution, making it ideal for backup and other similar applications.
The SH7216 group devices can operate from a single 3.3 V digital system power supply, which allows the external power supply system to be simplified, and they assure adequate dynamic range by adopting a 5 V analog system power supply.
Today’s industrial motor control applications demand very high performance and precision. Additionally, the functionality required in these applications is increasing as well; for example, multi-axis control is often required. Moreover, the systems used are becoming more complex, and higher performance and higher speeds are now required in FA equipment. While Renesas has already released the SH7211, which uses the high real-time performance SH-2A as the CPU core and includes 512 KB of flash memory, we have developed and are now releasing the SH7216 which increases the clock frequency by a factor of 1.25 from the 160 MHz of the SH7211 to 200 MHZ.
The SH7216 group adopts the SH2A-FPU, which adds an FPU function to the SH-2A, as the CPU core, and can perform double precision floating point operations at speeds up to ten times faster than previous products. This new group also provides up to 1 MB of high-speed flash memory to store the increasingly large programs associated with the higher functionality required in the latest equipment. This new group also provides up to 128 KB of on-chip RAM so that the previously required external SRAM or SDRAM is no longer needed. This can contribute to miniaturization and lower costs in application systems.
In these applications, high-speed communication functions have become indispensable along with the increasing performance. That is, industrial equipment must now support multiple high-speed communication protocols; earlier communication interfaces have now become inadequate, both in functionality and in communication bandwidth. While Renesas provides a product line of high-speed communication interfaces, such as Ethernet and USB, as products for use in ASSP devices, in the SH7216, these interfaces are integrated on the same chip. These microcontrollers also include a CAN controller to enable a wide range of industrial communication protocols. The Ethernet interface includes a media access controller (MAC*3) that conforms to the IEEE 802.3*4 standard, and can connect to a 10 or 100 Mbps Ethernet.
These devices are available in 176-pin LQFP (24 × 24 mm), 176-pin LQFP (20 × 20 mm), and 176-pin BGA (13 × 13 mm) packages.
