Renesas Technology America, Inc., a U.S. subsidiary of the new joint-venture semiconductor company established by Hitachi, Ltd. and Mitsubishi Electric Corporation today introduced the 16-bit, 25MHz H8 Value Series. The H8 Value Series MCUs are economical versions of the existing and most popular H8 devices that provide optimal performance.
The MCUs in the series combine versatile features, competitive pricing and full-featured development tools. They are ideal for GPS receivers, emission text equipment, label printers, touch screen controllers, bar code scanners, point-of-sale equipment and security systems and many other cost-sensitive products that require larger flash memory and more CPU performance than found in the traditional 8-bit MCUs.
To provide maximum system performance for low cost, the Renesas Value Series MCUs achieve 25MHz operating frequency speeds with a minimum instruction execution time of 40 nanoseconds (ns) for the H8S series devices and 80 ns for the H8/300H series devices. These devices have 4 or 8 Kilobytes (KB) of RAM to choose from and 128KB of ROM (flash or mask type). To address the need of low cost embedded systems, Renesas also offers devices in various operating voltage range - from 3-3.6V for the H8S and H8/300H devices and 4.5-5.5V for some of the H8/300H MCUs.
The H8 Value Series MCUs include a fast, 85-channel data transfer controller (DTC) and 4-channel direct memory access controller (DMAC). These functions off-load the central processing unit (CPU) when data is obtained from and sent to external memory, allowing higher system throughput and performance. Other on-chip resources include timers (8-bit, 16-bit and watchdog), 16-bit programmable pulse generator (PPG), data converters (8- or 12-channel 10-bit ADC and 2- or 4-channel 8-bit DAC), 2 or 3 channels of serial communication interface, and a smart card interface. The devices are available in 100-, 128- and 144-pin QFP packages. To address the need for large on-chip memory, Renesas also plans to offer pin compatible MCUs with 256KB of on-chip flash and Mask ROM next year.
According to Peter Carbone, director of marketing for System LSI at Renesas Technology America, Inc., "The introduction of the H8 Values Series is our commitment to offer more features at lower cost to our customers, so that their16-bit based products can achieve the highest level of competitiveness. We intended this product series to be the perfect entry for customers wanting to transition from their 8-bit MCU to 16-bit H8 MCU without a large price increase."
Renesas offers a wide range of development tools to facilitate the development of embedded applications using the H8 Value Series MCUs. They include an Evaluation Design Kit (EDK), low-cost E10A on-chip debugger with JTAG interface, powerful real-time, zero-wait-state E6000 in-circuit emulator, and a High Performance Embedded Workshop (HEW) software tool set with highly-optimized compiler, assembler, linker and debugger. Complete development kits (evaluation board, JTAG emulator and software tool chain) start at a low price of $399.00. Third-party vendors offer system design expertise as well as real-time operating systems, compilers, firmware and additional design and debug tools. H8 Value Series MCUs are code compatible with other H8 series MCUs, so system engineers can save time and cost by leveraging previously developed application code.
Customers can take advantage of user-friendly online training, extensive online technical documentation (hardware manual, application notes and more).
Renesas offers the MCUs in the H8 Value Series at fixed low-cost, single-volume prices that are published online. A stock is maintained to ensure quick availability, and detailed online information is provided to enable fast design and production decisions.
