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.
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.
< Development Background >
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.
< Product Details >
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.
