MN101E77 Series (Tentative)
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, remote controller, fax machine, music instrument and other applications.
This LSI brings to embedded microcomputer and applications flexible, optimized hardware configurations and a simple
efficient instruction set. MN101EF77G has an internal 128 KB of ROM 2 KB of RAM. Peripheral functions include 6 external
interrupts, 13 internal interrupts including NMI, 7 timer counters, 1 type of serial interfaces, A/D converter and 2 types of
watchdog timer. The system configuration is suitable for system control microcontroller such as camera, timer selector for VCR,
CD player, or MD.
With 4 oscillation systems (high-speed (internal frequency: 16 MHz), high-speed (crystal/ceramic frequency: max. 10 MHz)
/ low-speed (internal frequency: 5 kHz), low-speed (crystal frequency: 32.768 kHz) contained on the chip, the system clock can
be switched to high-speed frequency input (NORMAL mode) or to low-speed frequency input (SLOW mode).
The system clock is generated by dividing the oscillation clock. The best operation clock for the system can be selected by
switching its frequency ratio by programming. High speed mode has the standard mode which is based on the clock dividing
fxtl/frc by 2 (fxtl/2 or frc/2), and the double speed mode which is based on the clock not dividing fxtl or frc.
A machine cycle (minimum instruction execution time) in the standard mode is 200 ns when the original oscillation fxtl is
10 MHz. 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 fxtl is 10 MHz.
