MN101E56/57/76 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 applications.
This LSI brings to embedded microcomputer applications flexible, optimized hardware configurations and a simple efficient instruction
set. MN101EF57 series has an internal 128 KB of ROM and 6 KB of RAM. Peripheral functions include 5 external interrupts, 29 internal
interrupts including NMI, 12 timer counters, 4 types of serial interfaces, A/D converter, D/A converter, LCD driver, 2 types of watchdog
timer, data automatic function and buzzer output. The system configuration is suitable for in camera, timer selector for VCR, CD player, or
minicomponent.
With 5 oscillation systems (high-speed (internal frequency: 20 MHz), high-speed (crystal/ceramic frequency: max. 10 MHz) / low-speed
(internal frequency: 30 kHz), low-speed (crystal/ceramic frequency: 32.768 kHz) and PLL: frequency multiplier of high frequency) contained
on the chip, the system clock can be switched to high-speed frequency input (NORMAL mode), PLL input (PLL mode), or to 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 the 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 the 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 (maximum).

Internal system clock speed is changeable by selecting division ratio of oscillation clock. (Divided by 1, 2, 4, 16, 32, 64, 128)
Oscillation Circuit: 4 types
High-speed (Internal oscillation: frc), High-speed (crystal/ceramic: fosc),
Low-speed (Internal oscillation: frcs), Low-speed (crystal/ceramic: fx)
High-speed internal oscillation 20 MHz / 16 MHz (selectable)
Low-speed internal oscillation 30 kHz
Clock Multiplication Circuit:
PLL circuit output clock (fpll) fosc multiplied by 2, 3, 4, 5, 6, 8, 10,1/2 × frc multiplied by 4, 5 enabled
