ML2213
Speech Synthesiser with 1.5MBit ROM & Melody Circuit
Version 1.01, October 1998
GENERAL DESCRIPTION
The ML2213 combines a Mask-ROM speech synthesiser with a melody circuit and comes
with a simple serial interface to an microcontroller. It has an analog outputs for an amplifier
(speech playback) and a built-in driver for a piezo-electric speaker (melody playback). ML2213
is primarily designed for application in portable cellular phones.
ML2213 will come in a very small, 6.4 x 5.0mm sized 14-pin SSOP package (0.5mm pitch) housing 1.5MBit mask
ROM for speech and melody data. Selectable algorithms include 4-Bit OkiADPCM and linear and non-linear 8-Bit
OkiPCM (the latter achieves quality equivalent to 10-Bit linear PCM). In ADPCM mode and 4kHz sampling pro-
vided (from 4 to 16kHz selectable), the device outputs 90 seconds speech plus melodies. For both, 247 channels can
be defined. ML2213 comes in an ultra-small package, operates over a wide supply range from +2.2 ~ 5.5V and
satisfies the industrial temperature range.
