RISC II Series Microcontroller
1 General Description
The EPD2009 is an 8-bit RISC MCU embedded with the following features:
10-bit SAR A/D converter with
touch screen controller
Analog front end, 32×40 LCD
driver
Two 8-bit timers and one 16-bit
general timer with capture and
event counter functions
Embedded large size user RAM and
program/data memory
Watchdog timer, SPI, UART, and four
melody timers
PWM or current D/A
IR generator
The EPD2009 is ideally suitable for educational learning tools application that requires
high performance and low cost solution.
The MCU core is ELAN’s second generation RISC (RISC II) based IC. The core is
specifically designed as a low power and portable device. It supports Fast, Slow, and
Idle mode, as well as Sleep mode for low power consumption application.
