Product Details
ML22120TBZ0B-MX - Four-Channel AVAS Speech Synthesis LSI
ML22120TBZ0B-MX from ROHM Semiconductor / LAPIS Technology is an AVAS speech synthesis device with external serial-ROM support, four-channel mixing and digital control in a 32-pin TQFP.
Specifications were checked against the manufacturer data sheet and current distributor listing.
Overview
ML22120 combines LAPIS AVAS speech synthesis, external serial-ROM access, four-channel mixing and host control for long-form voice prompts and embedded audio playback.
Key Advantages
Supports up to 128 Mbit external ROM and as much as 17 minutes of stored speech depending on encoding conditions.
Provides four-channel mixing plus independent pitch and volume control for flexible voice guidance.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.
