SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER

Description

The M30220 group of single-chip microcomputers are built using the high-performance silicon gate CMOS

process using a M16C/60 Series CPU core. The M30220 group has LCD controller/driver. M30220 group is

packaged in a 144-pin plastic molded QFP. These single-chip microcomputers operate using sophisticated

instructions featuring a high level of instruction efficiency. With 1M bytes of address space, they are ca-

pable of executing instructions at high speed.

Features

• Basic machine instructions .................. Compatible with the M16C/60 series

• Memory capacity .................................. See figure memory expansion

• Shortest instruction execution time ...... 100ns (f(XIN)=10MHz)

• Supply voltage ..................................... 4.0V to 5.5V (f(XIN)=10MHz)

2.7V to 5.5V (f(XIN)=7MHz with software one-wait)

• Interrupts .............................................. 26 internal and 8 external interrupt sources, 4 software, 7 levels

(including key input interrupt)

• Multifunction 16-bit timer ...................... Timer A (output) x 8, timer B (input) x 6

• Real time port outputs .......................... 8 bits X 4 lines

• Serial I/O .............................................. 3 channel for UART or clock synchronous

• DMAC .................................................. 2 channels (trigger: 26 sources)

• A-D converter ....................................... 10 bits X 8 channels

• D-A converter ....................................... 8 bits X 3 channels

• Watchdog timer .................................... 1 line

• Programmable I/O ............................... 104 lines (32 lines are shared with LCD outputs)

• Output port ........................................... 16 lines (shared with LCD outputs)

_______

• Input port .............................................. 1 line (P77, shared with NMI pin)

• LCD drive control circuit ....................... 1/2, 1/3 bias

2, 3 and 4 time sharing

4 common outputs

48 segment outputs

built-in Charge-pump

• Key input interrupt ................................ 20 lines

• Clock generating circuit ....................... 2 built-in clock generation circuits

(built-in feedback resistor, and external ceramic or quartz oscillator)

Applications

Camera, Home appliances, Portable equipment, Drop meter, Audio, Office equipment, etc.
