4 / 49 page  RSC-4128 Data Sheet 4 P/N 80-0206-J © 2004 Sensory Inc. RSC-4128 Overview The RSC-4128 is a member of the Interactive Speech™ line of products from Sensory. It features a high- performance 8-bit microcontroller with on-chip ADC, DAC, preamplifier, RAM, ROM (except on ROM-less version), and optimized audio processing blocks. The RSC-4128 is designed to bring a high degree of integration and versatility into low-cost, power-sensitive applications. Various functional units have been integrated onto the CPU core in order to reduce total system cost and increase system reliability. The RSC-4128 operates in tandem with Sensory Speech™ 7 firmware, an ultra compact suite of recognition and synthesis technologies. This reduced software footprint enables, for example, products with over 150 seconds of compressed speech, multiple speaker dependent and independent vocabularies, speaker verification, and all application code built into the RSC-4128 as a single chip solution. Revolutionary Text-to-Speaker-Independent (T2SI) technology allows the creation of SI recognition sets by simply entering text. The CPU core embedded in the RSC-4128 is an 8-bit, variable-length-instruction microcontroller. The instruction set is similar to the 8051 microcontroller, and has a variety of addressing mode, MOV and 16 bit instructions. The RSC-4128 processor avoids the limitations of dedicated A, B, and DPTR registers by having completely symmetrical sources and destinations for all instructions. The RSC-4128 provides a high level of on-chip features and special DSP engines, providing a very cost effective mixed signal platform for general-purpose applications and development of custom algorithms. The full suite of industry standard tools for easy product development makes the RSC-4128 an ideal platform for consumer electronics.
