MN101EFA8/A7/A3/A2/G0 Series

8-bit Single-chip Microcontroller

PubNo. 216A8-015E

1.1 Overview

1.1.1

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 automotive power window,

camera, TV, CD, printer, telephone, home appliance, PPC, fax machine, music instrument and other applications.

This LSI brings to embedded microcomputer applications flexible, optimized hardware configurations and a sim-

ple efficient instruction set. MN101EFA7G/A8G/A2G/A3G/G0G have an internal 128 KB of ROM and 6 KB of

RAM. MN101EFA7D/A8D/A2D/A3D/G0D have an internal 64 KB of ROM and 4 KB of RAM. Peripheral func-

tions include 5 external interrupts (3 external interrupts in MN101EFAG0G(D)), including NMI, 10 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 oscillation systems (internal frequency: 16 MHz, high-speed crystal/ceramic frequency: max. 10 MHz,

low-speed 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 50 ns (max-

imum).
