ML2201

FEDL2201-01 1 Semiconductor ML2201-XXX Speech Synthesizer LSI with on-chip 384K Mask ROM This version: Mar. 2000 GENERAL DESCRIPTION The ML2201 is a PCM-based speech synthesizer LSI having an on-chip 384K Mask ROM, D/A Converter and Low Pass Filter. Utilizing the serial interface enables smaller footprint packaging, which makes the chip an ideal choice for a pre-recorded message subsystem used with today’s size-critical applications. FEATURES Sampling Frequency (Selectable for each single phrase) 4.0/5.3/6.4/8.0/10.6/12.8/16.0 kHz On-chip 384 Kbit Mask ROM Maximum Playback Time (At fEXTCLK = 4.096 MHz) 12.0 sec At fSAM = 4.0 kHz 6.0 sec At fSAM = 8.0 kHz 3.0 sec At fSAM = 16.0 kHz External Clock Frequency Range * fEXTCLK = 3.5 to 4.096 MHz (Typ.) to 17.0 MHz On-chip Phrase Control Table Maximum Number of Phrases: 31 Phrases Built-in 10-bit Current-Output Type D/A Converter Built-in LPF Packaging: 8-pin Plastic SSOP (SSOP8-P-44-0.65-K) (Product Code: ML2201-XXX MBZ060) Power Supply Voltage: +2.0 to +5.5 V * Note: As of February 2000, ceramic oscillation on this chip is under development and thus the chip is not functional with a ceramic oscillator. The manufacturer intends to add a ceramic oscillation option to the chip.
