MN101E50 Series
8-bit Single-chip Microcontroller
 Overview
The MN101E series of 8-bit single-chip microcomputers (the memory expansion version of MN101C series) incorporate
multiple types of peripheral functions. This chip series is well suited for camera, VCR, MD, TV, CD, LD, printer, telephone,
home automation, pager, air conditioner, PPC, fax machine, music instrument and other electrical appliances.
This LSI has embedded flexible microcomputer applications, optimized hardware configurations and a simple yet efficient
instruction set. MN101EF50D has an internal 64 KB of ROM and 4 KB of RAM. Peripheral functions include 5 external
interrupts, 25 internal interrupts including NMI, 11 timer counters, 4 types of serial interfaces, A/D converter, LCD driver,
watchdog timer and buzzer output. The system configuration is suitable for system control microcontrollers such as cameras,
timer selectors for VCR, CD players or minicomponents.
With 4 oscillation systems (high-speed internal frequency: 20 MHz, high-speed crystal/ceramic frequency: max. 10 MHz /
low-speed crystal/ceramic frequency: 32.768 kHz and PLL: frequency multiplier of the high-speed frequency) contained in the
chip, the system clock can be switched to high-speed frequency input (NORMAL mode), 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 optimum
operating clock for the system can be selected by switching its frequency ratio by programming.
The machine cycle (minimum instruction execution time) is 100 ns when the external oscillation fosc is 10 MHz (PLL is not
used). The machine cycle is 50 ns (maximum) when the internal oscillation frequency is 20 MHz (PLL is not used). A machine
cycle in the PLL mode is 50 ns (maximum).
