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

Renesas 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 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 1µs 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.
