Preliminary Data Sheet
RSC-464 Overview
The RSC-464 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, and optimized audio
processing blocks. The RSC-464 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-464 operates in tandem with FluentChip™ firmware, an ultra compact suite of recognition and synthesis
technologies. This reduced software footprint enables, for example, products with 60 seconds of compressed
speech, multiple speaker dependent and independent vocabularies, speaker verification, and all application code
built into the RSC-464 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-464 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-
464 processor avoids the limitations of dedicated A, B, and DPTR registers by having completely symmetrical
sources and destinations for all instructions.
The RSC-464 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-464 an ideal platform for consumer
electronics.
