Renesas Technology’s New H8SX Family Devices Offer EXDMA for TFT Displays and Fast A/D and Analog Peripherals for Scanners and Office Automation Systems

August 4, 2008

Renesas Technology America, Inc. today introduced ten new microcontrollers (MCUs) in the H8SX family that provide a faster analog-to-digital (A/D) converter and a more precise digital-to-analog (D/A) converter. The new 32-bit, 50MHz devices give embedded systems better analog signal-processing capabilities for interfacing to TFT displays, sensors, scanners, and other types of input/output elements found in PCs, digital consumer products, office automation (OA) and industrial equipment. The new CISC (Complex Instruction Set Computer) MCUs are members of the H8SX/1645, H8SX/1635, H8SX/1665, and H8SX/1655 product groups.

According to Ritesh Tyagi, director of the system LSI business unit, Renesas Technology America, “The enhanced analog capability is required in many applications, especially when large amounts of data need to be processed in a relatively short period of time. The two independent 10-bit A/D units offer capabilities to rapidly convert analog inputs to digital signals with less than 1 us conversion time. In addition, the H8SX has a multi bus architecture with built-in DMA and EXDMA units that can execute data transfer and JPEG image processing in parallel. The enhanced A/D and D/A converters maintain compatibility with existing products, so the settings used in systems built with the previous H8SX MCUs can be maintained without time-consuming modifications.”

The new MCUs have up to 512KB on-chip flash memory and 40KB RAM. The flash memory is accessible in a single cycle at 50MHz operating frequencies for fast response time. A powerful CISC instruction set and the single-cycle flash access combine to ensure deterministic system operation for time-critical control routines.

As with the H8SX current products, the new MCUs provide a comprehensive set of on-chip peripheral functions, making it possible to build a high-functionality end products at low cost. Among the peripherals are a programmable pulse generator (PPG) that can be teamed with a 16-bit timer pulse unit to implement pulse-output operation, and an I2C bus interface. A multi-channel serial communication interface (SCI) includes two high-speed channels that support 720kbps rates, and one of its operating modes accepts a clock input from an 8-bit timer, allowing flexible, programmable transfer rates.

The H8SX/1645, H8SX/1635, H8SX/1665, and H8SX/1655 devices have 120-pin or 144-pin LQFP packages that are compatible with current products, so customers can easily upgrade system performance and functionality using existing hardware. Moreover, the MCUs in the H8SX/1645 and H8SX/1665 groups are also available in a space-saving 145-pin LGA package with a mounting area approximately 80 percent smaller than a 144-pin LQFP. All of the new MCUs have six power-down modes to reduce power consumption, including a Deep Software Standby mode that offers greater efficiency than the Software Standby mode.

For system design and debugging, customers can use the USB-bus powered E10A-USB emulator as a development environment. Additionally, they can obtain a comprehensive suite of other hardware and software tools from Renesas and a global community of third-party suppliers.
