RISC II Series Microcontroller
1 General Description
The ePS5001 is an 8-bit RISC MCU embedded with a 5×40 LCD driver along with two
8-bit timers, one 16-bit general timer, and a Watchdog Timer. It has also an on-chip
128 bytes RAM and 2K 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 ePS5001 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 0.
■ Do not use Register BSR1 (07h) Bit 7 ~ Bit 0.
■ Check that the range of BSR (05h) and BSR1 (07h) are only 0x00.
■ Do not use LCD RAM 28h ~ FFh.
■ Do not use JDNZ at FSR1 (04h) special register.
■ Do not use JDNZ at LCDARL (09h) special register.
■ Do not use PUSH, POP by "MOV A,r" to avoid affecting S_Z.

Note:
1. Slow Mode switches to Fast Mode at Time = 0 ms.
2. System clock will switch to Fast Mode after a delay of 0.1ms by oscillator and
enters into Fast Mode (i.e., system clock will be at 200, 300, or 500kHz).
3. High frequency RC will be stabilized at Time=Ts (15 µs~30 µs).
