Data Sheet
RSC-4128
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, 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 FluentChip™ firmware, an ultra compact suite of recognition and synthesis
technologies. This reduced software footprint enables, for example, products with 3 minutes 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.
