32-bit RISC microcontroler for embedded use

1 March 2000 DSP, Micros & Memory

Epson is offering a 32-bit RISC single-chip microcomputer family that it claims delivers high performance and optimised architecture for embedded applications. The first family device is the E0C33A104 32-bit single-chip microcontroller featuring voice synthesis and voice recognition capabilities. The device incorporates the Epson E0C33 CMOS RISC core. The internal MAC (multiplication and accumulation) provides DSP capabilities.

The E0C33A104 is an ideal one-chip solution for portable consumer electronics and voice applications such as handheld PCs, personal digital assistant, digital cameras, toys and automation products. The E0C33A104 tool set includes an optimised C compiler which allows faster coding and reducing time to market and a full in-circuit emulator (ICE) development system.

The E0C33A104 and the E0C33 family of products are supported by Epson's own ROS33, realtime OS, based on uITron 3.0 (level S). ROS33 is royalty-free and complete source code is available. Additionally, the E0C33A104 is backed by robust, linkable voice compression technology (VOX33) which provides voice compression and decompression at high ratios.

Voice speed can also be changed from x2 to x1/4 and the voice pitch can be changed from x2 (high) to 1/3 (low). Speaking and listening capabilities are also included in the library.
