eSC Series
Tiny Turbo Controller with Single Speech Channel
1 General Description
The eSC series IC’s are 4-bit microcontroller based sound processor with single-channel
speech audio function. The series has a powerful 4-bit CPU that handles most of the
speech functions. Wide range sampling rate and different volume levels are supported. It
provides a synthesized speech to obtain good quality speech as well as one 4-bit input
port, three 4-bit I/O ports, and one 4-bit output port (applicable to eSC100/120/170/200/
270/320). 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.
In addition to Sleep mode, the eSC series IC’s also offer Green mode which allows
continuous operation at reduced or very low power consumption. Normal operation
resumes at a preset time.
The enhanced functions will facilitate users in creating a wide variety of devices with new
fancy features.
2 Features
System clock:
z 4 MHz @ 2.2 volts ~ 5.1 volts
z 6 MHz @ 2.4V ~ 5.1V
Auto optional crystal oscillator or RC oscillator
Input/Output ports:
z One Input port (P1) with software controlled pull low resistor
z Three input/output ports (P2 ~ P4)
Ä P2 & P3 are software controlled with pull low resistor and wake-up function
Ä P4 is applicable to eSC065/080/100/120/170/200/270/320
z One output port (P5) applicable to eSC100/120/170/200/270/320
Sleep mode to conserve power (less than 1µA @ 3V standby current)
Green mode for continuous operation at reduced or very low power consumption
(less than 15µA @ 3V)
4 bits RISC type controller, each instruction takes 2 (90%) or 4 clock cycles
12 bits width per instruction, each instruction takes 1 (90%) or 2 words
Total of 4 interrupts are available:
z 2 interrupts for speech/high resolution timer operation
z 1 interrupt for timer
z 1 general purpose external interrupt
