Overview

The MN101C series of 8-bit single-chip microcontroller incorporates multiple types of peripheral functions.

This chip series is well suited for camera, VCR, MD, TV, CD, LD, printer, telephone, home automation

products, pager, air conditioner, PPC remote control, fax machine, musical instrument, and other applica-

tions.

The MN101C77 series brings to embedded microcontroller applications flexible, optimized hardware

configurations and a simple efficient instruction set. The MN101C77C has an internal 48 KB of ROM and

3 KB of RAM. Peripheral functions include 5 external interrupts, 17 internal interrupts including NMI,

independent 6 timer counters, 4 sets of serial interfaces, A/D converter, D/A converter, watchdog timer,

automatic data transfer, synchronous output, buzzer output, and remote control output. The configura-

tion of this microcontroller is well suited for application such as a system controller in a camera, VCR

selection timer, CD player, or MD

.

With two oscillation systems (max.20 MHz/32 kHz) contained on the chip, the system clock can be

switched to high speed oscillation (

), or to low  speed oscillation (

). The

system clock is generated by dividing the oscillation clock. The best operation clock for the system can

be selected by switching its frequency by software. There are 2 choices for high speed oscillation : the

normal mode, which has a system clock based on the clock (fosc/2) divided by 2, and

the 2x-speed

mode, which has a system clock based on the same cycle clock (fosc).

On the normal mode, when the oscillation source(fosc) is 8 MHz, 

 is for 250 ns, and when fosc is 20 MHz, it is 100 ns. On the 2x-speed mode, CPU is operated with

the same cycle to the external clock, when fosc is 8 MHz, minimum instructions execution time is 125 ns.

The packages are 64-pin LQFP and 64-pin TQFP (under development).

This manual describes the following models of the MN101C77 series. These products have same pe-

ripheral functions. (Refer to chapter 18 Flash EEPROM for Flash version.)
