EASY SOUND® – eSM Series
Tiny Controller-Based Speech Synthesizer
1 General Description
eSM Series are single chip Voice/Dual tone Melody/Dual tone Sound Effect synthesizer ICs. It
contains one 4-bit input port (provided for eSM005 and above), two 4-bit I/O ports, a tiny
controller, and adapts improved algorithm to achieve pure speech. User's applications, such as
section combination, trigger modes, control outputs, keyboard matrix, and other logic functions,
are easily implemented by programming through its tiny controller

*eSMP020 is a flexible OTP IC which can be programmed to clone any of its smaller sister IC’s,
i.e., eSM003 ~ eSM020.
*If to verify the kit board by using the kernel chip. In order to ensure the characteristic, please
double confirm it by using eSMP020.
Single power supply 2.4 V ~ 5 V
One 6-bit timer overflow control
PCM, ASPCM, and ASPCM+ synthesizer, and dual tone melody/sound effect generator
4K~32K Hz playing speed for voice play-back
Multiple tempos for dual tone melody/sound effect play-back
Variable beats for dual tone melody/sound effect play-back
Multiple volume control levels
Fixed current D/A output to drive external connected transistor for voice output
Pin P3.2 can be programmed as IR communication pin to generate 38KHZ carrier
The IR function of eSM003 is only available in assembly language.
