ePS5005
RISC II Series Microcontroller
1 General Description
The ePS5005 is an 8-bit RISC MCU embedded with an 11×60 LCD driver along with
two 8-bit timers, one 16-bit general timer, and a watchdog timer. It also has on-chip
512 bytes RAM and 16K words program ROM. It is highly ideal for advance scientific
calculator application, particularly those requiring high performance and low cost
solution.
The MCU core is one of ELAN’s second generation RISC based IC’s, known as RISC II
(RII) series. The core was specifically designed for low power and portable device
applications. The ePS5005 also supports Fast, Slow and Idle modes, as well as Sleep
mode to enhance its low power consumption features.
IMPORTANT NOTES !
■ Do not use Register BSR (05h) Bit 7 ~ Bit 3.
■ Do not use Register BSR1 (07h) Bit 7 ~ Bit 3.
■ Check the range of BSR (05h) and BSR1 (07h) are only 0x00~0x03.
■ Do not use LCD RAM 3Ch ~ 3Fh.
■ Do not use Registers JDNZ at FSR1 (04h) special register.
