SAN JOSE, Calif.--(BUSINESS WIRE)--June 10, 1999--

Voice Synthesis and Voice Recognition Optimized

for Low-Power Portable Solutions

Epson Electronics America has announced the E0C33 family of 32-bit RISC microcontrollers designed to deliver the key attributes required in embedded applications, namely high performance, optimized architecture, low-power and low-current consumption.

The first family device to be offered immediately is the E0C33A104 32-bit single chip microcontroller featuring voice synthesis and voice recognition capabilities. The device incorporates the Seiko Epson E0C33 CMOS RISC core, 4K bytes of ROM, up to 6K bytes of RAM, a 128 ch. intelligent DMA controller, 10-bit, 8 channel ADC, 8-bit 2 channel DAC, and several timers. The internal MAC (multiplication and accumulation) provides DSP capabilities.

The E0C33A104 features a small core, and low-power consumption, making it an ideal one-chip solution for portable consumer electronics and voice applications such as handheld PCs, personal digital assistants, digital cameras and office automation products such as printers, scanners and projectors.

The E0C33A104 tool set includes an optimized C compiler, allowing for faster coding and reducing time to market, and a full in-circuit emulator (ICE) development system.

Realtime Operating System and Voice Middleware Support

The E0C33A104 and the E0C33 family of products is supported by Epson's own ROS33, realtime OS, based on uITron 3.0. (level S). ROSS is royalty-free and complete source code is available. Additionally, the EOC33A104 is backed by robust, linkable voice middleware that includes Seiko Epson's exclusive voice compression technology, VOX, which provides voice compression and decompression at high compression ratios. As an example, an 8MHz sampled voice can be compressed to 8kbps standard to maximum 2 kbps even while allowing various compression ratios to be selected.

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

Price and Availability

The EPSON E0C33A104 starts at a unit price of $7.77 for quantities of 100,000 devices. It is also available in die form.
