eSA Series
General Purpose Tiny Controller with
Four-Channel Speech and Melody Synthesis
1 General Description
The eSA Series IC’s are 4-bit microcontroller based sound processors with audio
function, like multi-channel speech and instrument playback. The series has a
powerful 4-bit CPU that handles most of the speech and melody functions. Its four
channels can be configured as speech or melody, and all the channels can be
simultaneously played back. Speech synthesis is implemented by software. Wide
range sampling rate and different volume levels are supported. The eSA Series
provides real instrument waveform to obtain good quality melody, as well as one 4-bit
input port, three 4-bit I/O ports (Port 2 is applicable to eSA010 only), and one 4-bit
output port (applicable to eSA100 & eSA120 only). By programming through the
microcontroller, applications, such as section combination, trigger mode, output
control, keyboard matrix, and other logic functions are easily implemented.
In addition to Sleep mode, the eSA Series IC’s also offer Green mode which allows
reduced but continuous operation at very low power consumption. Normal operation
resumes at a preset time. These enhanced versatile features allow users to create
products with a wide variety of new fancy ideas.
2 Features
System clock: 3.58 M [email protected] volts ~ 5.1 volts
Auto Optional crystal oscillator or RC oscillator (only RC oscillator is applicable to
eSA010)
Input/Output ports:
• One Input port (P1) with software controlled pull-low resistor.
• Three input /output ports (P2 ~ P4)
P2 & P3 are software controlled with pull-low resistor and wake-up function
(eSA010 has only one input/output port, P2)
• One output port (P5) applicable to eSA100 & eSA120 only.
Sleep mode to conserve power, less than 2µA@3V standby current
Green mode for reduced but continuous operation at very low power consumption
(less than 15µA@3V) (not supported for eSA010)
4 bits RISC type controller, each instruction takes 1 (90%) or 2 clocks
12 bits width per instruction, each instruction takes 1 (90%) or 2 words
One interrupt entrance. Multiple interrupt sources.
Total of six interrupts are available:
• Four interrupts for speech/melody operation
• One for timer
• One external interrupt for general purpose (not supported for eSA010)
