SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER

Description

The M30221 group of single-chip microcomputers are built using the high-performance silicon gate CMOS

process using a M16C/60 Series CPU core. The M30221 group has LCD controller/driver. M30221 group is

packaged in a 120-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 1.1.3 Memory Expansion

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

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

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

• Interrupts .............................................. 24 internal and 8 external interrupt sources, 4 software

interrupt sources; 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 3 lines,6 bits X 1 lines

• Serial I/O .............................................. 2 channels for UART or clock synchronous

• DMAC .................................................. 2 channels (trigger: 24 souces)

• A-D converter ....................................... 10 bits X 7 channels

• D-A converter ....................................... 8 bits X 2 channels

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

• Programmable I/O ............................... 83 lines (26 lines are shared with LCD outputs)

• Output port ........................................... 14 lines (14 lines are shared with LCD outpus)

• Input port .............................................. 1 line (P77, shared with NMI pin) Specifications written in this manual

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

2, 3 and 4 duty

4 common outputs

are believed to be accurate, but are

not guaranteed to be entirely free of

error.

Specifications in this manual may

40 segment outputs

built-in charge pump

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

be changed for functional or

performance improvements. Please

make sure your manual is the latest

edition.

• 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, Audio, office equipment, etc.
