NUVOTON KM101EF93GXW

The KM101E series of 8-bit single-chip microcontrollers incorporate multiple types of peripheral functions. This chip series is well suited for camera, TV, CD, printer, telephone, home appliance, PPC, fax machine, music instrument and other applications. This LSI brings to embedded microcontroller applications flexible, optimized hardware configurations and a simple efficient instruction set. KM101EF93G have an internal 128 KB of ROM and 6 KB of RAM. Peripheral functions include 5 external interrupts, including NMI, 9 timer counters, 4 types of serial interfaces, A/D converter, watchdog timer and buzzer output. The system configuration is suitable for system control microcontroller. With 3 oscilltion systems (internal frequency: 16 MHz, high-speed crystal/ceramic frequency: max. 10 MHz, lowspeed crystal/ceramic frequency: 32.768 kHz) contained on the chip, the system clock can be switched to high-speed frequency input (NORMAL mode) or PLL input (PLL mode), or low-speed frequency input (SLOW mode). The system clock is generated by dividing the oscillation clock or PLL clock. The best operation clock for the system can be selected by switching its frequency ratio by programming. High speed mode has NORMAL mode which is based on the clock dividing fpll, (fpll is generated by original oscillation and PLL), by 2 (fpll/2), and the double speed mode which is based on the clock not dividing fpll. A machine cycle (minimum instruction execution time) in NORMAL mode is 200 ns when the original oscillation fosc is 10 MHz (PLL is not used). A machine cycle in the double speed mode, in which the CPU operates on the same clock as the external clock, is 100 ns when fosc is 10 MHz. A machine cycle in the PLL mode is 50ns (maximum).
