`Operation speed: DC ~ 10MHz clock input.
`Dual clock operation
􀁺 * High frequency oscillator can select among Crystal, RC, or PLL (phase lock loop)
􀁺 * Low frequency oscillator can select between Crystal or RC mode
`Totally 272 bytes SRAM
􀁺 * 144 bytes general purpose register
􀁺 * 128 bytes on chip data RAM
`4K*13 bits OTP - ROM (One Time Programmable - Read Only Memory)
`Up to 28 bi-directional tri-state I/O ports
􀁺 * Typically, 12 bi-directional tri-state I/O ports.
􀁺 * 16 bi-directional tri-state I/O ports shared with LCD segment output pin.
`8-level stack for subroutine nesting
`8-bit real time clock/counter (TCC)
`One infrared transmitter/PWM generator function
`Four sets of 8 bits auto reload down-count timer can be used as interrupt sources
􀁺 * Counter 1: independent down-count timer
􀁺 * Counter 2, High Pulse Width Timer (HPWT), and Low Pulse Width Timer (LPWT) shared with IR function.
`Programmable free running on chip watchdog timer (WDT). This function can operate on Normal, Green and Idle mode.
`Operation modes:
􀁺 *Normal mode: The CPU operated on frequency of main oscillator (Fm)

Description

This LSI is an 8-bit RISC type microprocessor with high speed CMOS technology and low power consumption. Integrated onto a single chip are on chip watchdog timer (WDT), Data RAM, ROM, programmable real time clock counter, internal/external interrupt, power down mode, LCD driver, infrared transmitter function, and tri-state I/O. The EM78P468N provides multi-protection bits to protect against intrusion of user's code in the OTP memory and a seven option bits to accommodate user's requirements. It also provides an especial 13 bits customer ID option.
With its OTP-ROM feature, this LSI offers a convenient way of developing and verifying user's programs. Moreover, user developed code can be easily programmed with the ELAN writer.
