描述 Description

The EPD2007 is an 8-bit RISC MCU which embedded a 10 bits SAR A/D converter with
touch screen controller, an analog front end, 16 x 56 LCD driver, two 8-bit timers and
one 16-bit general timer with capture and event counter functions, IR generator,
Watchdog Timer, SPI, UART, and four melody timers, a PWM and a current D/A.
Besides, it has an embedded large size user RAM and program/data memory. It is
suitable for educational learning tools application requiring high performance and low
cost solution.
The MCU's 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.
