The SH72546RFCC (FCC = flash on-chip calibration chip) device is a preproduction device optimized for control program development, offering a set of features tailored to aid software design and debug. It forms the basis for an upcoming mass-production product family that will have performance, package, and pin arrangement compatibility. Engineers performing system development using the SH72546RFCC will be able to make a speedy and seamless transition to lower-cost mass production devices.
Paul Fox, director, automotive business unit at Renesas Technology America, Inc., pointed out that the new device demonstrates the company's technology leadership in two areas. "First, this fast and powerful 32-bit MCU showcases the first use of a 90nm process to build an MCU with on-chip flash memory. And second, the very large capacity of that flash -- 3.75 Mbytes, plus 128 Kbytes of on-chip flash memory with functions virtually equivalent to those of EEPROM (electrically erasable and programmable read-only memory) -- means that this SuperH device readily can handle the sophisticated control programs. Our automotive customers are developing the complex programs necessary to ensure that future vehicles will be able to meet stricter emission regulations and environmental protection measures, and the new SH72546RFCC MCU aids that development work."
The fast, 200MHz, 32-bit SH-2A CPU core of the SH72546RFCC is an enhanced superscalar design with a built-in double precision floating point unit (FPU) that delivers about four times the performance of the 80MHz Renesas SH-2E (SH-2 and single precision FPU) core used in the powertrain systems of many of today's vehicles. A cache unit allows single-cycle access to the large on-chip flash memory at 200MHz for high-speed application processing.
The comprehensive on-chip peripheral functions that the MCU provides for real-time engine and transmission control applications include a multifunction timer unit (ATU-III: advanced timer unit III) with up to 106 outputs, a high-speed 37-channel 12-bit A/D converter, CAN (controller area network) interface, and an SPI (serial peripheral interface). To improve program development efficiency, the SH72546RFCC device has a large-capacity on-chip emulation RAM* that is separate from the user RAM. This RAM overlaps the flash memory area, and allows real-time adjustment of application program control parameters while data is rewritten as desired during microcontroller operation. There are also debugging functions such as an AUD (advanced user debugger).
Available system development tools include the USB bus-powered E10A-USB on-chip debugging emulator that requires no external power supply, and the E200F full-spec emulator. Renesas also offers the High-performance Embedded Workshop integrated development environment with compiler, assembler, and linker products.
Plans for mass-production specification products, without the SH72546RFCC's debugging functions (emulation RAM, etc.), include products with extended on-chip flash memory and RAM capacities, and low-pin-count products.
