M30220 Group
Description
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

• Supply voltage ..................................... 4.0V to 5.5V (f(XIN)=10MHz)
2.7V to 5.5V (f(XIN)=7MHz with software one-wait)
• Interrupts .............................................. 25 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: 24 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)
_______
• Input port .............................................. 1 line (P77, shared with NMI pin) Specifications written in this manual
• LCD drive control circuit ....................... 1/2, 1/3 bias
are believed to be accurate, but are
2, 3 and 4 time sharing
4 common outputs
48 segment outputs
not guaranteed to be entirely free of
error.
Specifications in this manual may
be changed for functional or
built-in set-up condencer circuit performance improvements. Please
• Key input interrupt ................................ 20 lines
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.

SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
• Bit 7: Stack pointer select flag (U flag)
Interrupt stack pointer (ISP) is selected when this flag is “0” ; user stack pointer (USP) is selected
when this flag is “1”.
This flag is cleared to “0” when a hardware interrupt is acknowledged or an INT instruction of software
interrupt Nos. 0 to 31 is executed.
• Bits 8 to 11: Reserved area
• Bits 12 to 14: Processor interrupt priority level (IPL)
Processor interrupt priority level (IPL) is configured with three bits, for specification of up to eight
processor interrupt priority levels from level 0 to level 7.
If a requested interrupt has priority greater than the processor interrupt priority level (IPL), the interrupt
is enabled.
• Bit 15: Reserved area
The C, Z, S, and O flags are changed when instructions are executed. See the software manual for
details.
