Specification

Overview

  • General Description

    The ePS6900 is an 8-bit RISC MCU embedded with a 32 98 LCD driver along with two 8-bit timers, one 16-bit general timer, and a Watchdog Timer. Furthermore, ePS6900 is equipped with 8K bytes RAM and 96K words program ROM. It is highly ideal for advance scientific calculator application, particularly those that need a high performance at low cost solution. The MCU core is a one of ELAN's second generation RISC based IC's, knows as RISC II(RII) series. The core was specifically designed for low power and portable device applications. The PS6900 also supports Fast, Slow and Idle modes, as well as Sleep mode to enhance its low power consumption features.
