Overview
This LSI is a single-chip microcontroller unit (MCU) built around the H8, 300H CPU. Four I, O ports, ROM, RAM, EEPROM, a random number generator (RNG), a watchdog timer (WDT), a firewall management unit (FMU), interval timers (TMR1, TMR2), I2C bus interface (IIC2), synchronous serial communication unit (SSU), and a coprocessor are included. Operating at a maximum 10-MH- internal clock rate, the H8, 300H CPU rapidly executes bit manipulation instructions, arithmetic and logic instructions, and data transfer instructions. The on-chip coprocessor executes modular multiplications (such as ABR-1 modN + kN), which are used to calculate modular exponentiation XY modN, and DES calculation processing at a high speed. Table 1 lists the features of this LSI. Table 1
