32 bit RISC with built-in ROM
28 March 2001
DSP, Micros & Memory
Epson has developed a 32 bit RISC MCU integrating enhanced peripheral circuits with built-in ROM based on the Epson E0C33209. Two models will be launched to the market: the mask ROM built-in E0C33264 and the E0C332129 models.
Both devices include a built-in high-speed MAC (multiplication and accumulation) instruction, a multiplexed AD converter, DMA, HDMA, 4 ch SIO and various timers. These functions make them suitable for classic DSP applications, especially for software coded and signal processing (voice recognition and text-to-speech). Typical applications would be multimedia equipment such as DVD, HMI and classic PDA terminals.
For software development, Epson has prepared a wide range of licence-free middleware including voice compression and decompression, voice recognition, JPEG, audio, realtime operation system, graphic user interface and compact flash card interface.
