eSHS Series
Tiny Controller with Single Speech Channel
1 General Description
The eSHS series IC’s are 4-bit microcontroller based sound processors. The series is
equipped with a synthesized speech feature to obtain good quality voice. The series
also offers two 4-bit I/O ports (except for eSHS007/012/015 which do not support
P2.3/P3.0). By programming through the microcontroller, applications, such as section
combination, trigger mode, output control, keyboard matrix, and other logic functions
are easily put into effect.
2 Features
System clock: 2 MHz @2.4V ~ 5.5V
7~60 seconds voice capacity are provided (@6kHz sample rate)
Sleep mode to conserve power, less than 2µA@3V standby current
RC oscillator
Built in 4-bit tiny controller
Input/Output ports:
• Two input/output ports (P2 ~ P3)
P2 is software controlled with pull-low resistor
eSHS007/012/015 only provide P2.0~P2.2 / P3.1~P3.2
• I/O Pin P3.2 can be modulated with 38.5kHz carry signal to implement IR
function
• I/O Pin P3.3 can be configured as flash with volume application
Single ROM for voice program with a maximum of 32K program addressing size
Reset pin is available
Readable ROM data is available
4-level stack for subroutine nesting
Built-in PWM Direct Drive
PCM, 5-bit eDPCM, and 6-bit eDPCM algorithms are available for speech
synthesis (to provide silence compression). These are transparent to user.
Supports self-test function for checking IC status
Waveform Mark function and Waveform Control Port (WCP) are provided to control
operation that synchronizes with voice
Support EASY/Assembly language for developing codes
