External Serial Flash ROM Type Hi-Fi Voice Synthesis ICs (SPI Interface)

ROHM's external Flash ROM Hi-Fi voice synthesis ICs add versatility to sets incompatible with mask ROM IC types by enabling voice data storage in an external serial Flash ROM of the customer's choice. In addition, the units can accommodate set/specification changes by allowing modification of the voice data, even after mounting.

Features

Serial Flash ROM compatibility * in the industry's smallest size
ROHM's external serial Flash ROM voice synthesis ICs are offered in the industry's smallest package. Voice data can be written without requiring hardware modification. Ideally suited for compact devices incompatible with mask ROM type ICs due to size restrictions.
