SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
Description
The M16C/62A group of single-chip microcomputers are built using the high-performance silicon gate
CMOS process using a M16C/60 Series CPU core and are packaged in a 100-pin plastic molded QFP.
These single-chip microcomputers operate using sophisticated instructions featuring a high level of instruc-
tion efficiency. With 1M bytes of address space, they are capable of executing instructions at high speed.
They also feature a built-in multiplier and DMAC, making them ideal for controlling office, communications,
industrial equipment, and other high-speed processing applications.

Input
Reset input Input
Function
Supply 2.7V to 5.5 V to the VCC pin. Supply 0 V to the VSS pin.
This pin switches between processor modes. Connect this pin to the
VSS pin when after a reset you want to start operation in single-chip
mode (memory expansion mode) or the VCC pin when starting
operation in microprocessor mode.
A “L” on this input resets the microcomputer.

Clock input
Clock output
Input
Output
These pins are provided for the main clock generating circuit.Connect
a ceramic resonator or crystal between the XIN and the XOUT pins. To
use an externally derived clock, input it to the XIN pin and leave the
XOUT pin open.

supply input
This pin selects the width of an external data bus. A 16-bit width is
selected when this input is “L”; an 8-bit width is selected when this
input is “H”. This input must be fixed to either “H” or “L”. Connect this
pin to the VSS pin when not using external data bus.
This pin is a power supply input for the A-D converter. Connect this
pin to VCC.
This pin is a power supply input for the A-D converter. Connect this
pin to VSS.

Input
This pin is a reference voltage input for the A-D converter.
Input/output
This is an 8-bit CMOS I/O port. It has an input/output port direction
register that allows the user to set each pin for input or output
individually. When used for input in single-chip mode, the port can be
set to have or not have a pull-up resistor in units of four bits by
software. In memory expansion and microprocessor modes, selection
of the internal pull-resistor is not available.
Input/output When set as a separate bus, these pins input and output data (D0–D7).
Input/output This is an 8-bit I/O port equivalent to P0. P15 to P17 also function as
external interrupt pins as selected by software.
D8 to D15
Input/output When set as a separate bus, these pins input and output data (D8–D15).

(A0–A7) separated in time by multiplexing.

If the external bus is set as a 16-bit wide multiplexed bus, these pins
Input/output input and output data (D0–D6) and output address (A1–A7) separated
in time by multiplexing. They also output address (A0).
Input/output This is an 8-bit I/O port equivalent to P0.
Output
These pins output 8 middle-order address bits (A8–A15).
Input/output If the external bus is set as a 16-bit wide multiplexed bus, these pins
Output
input and output data (D7) and output address (A8) separated in time
by multiplexing. They also output address (A9–A15).
Input/output This is an 8-bit I/O port equivalent to P0.
Output
Output
These pins output A16–A19 and CS0–CS3 signals. A16–A19 are 4 high-

x : Nothing is mapped to this bit
? : Undefined
The content of other registers and RAM is undefined when the microcomputer is reset. The initial values must therefore be set.
Note 1: When the VCC level is applied to the CNVSS pin, it is 0316 at a reset.
Note 2: “0016” is read out when set bit 7 (SDDS) of the UART2 special mode register ( address 037716) to “1”.
