SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
DESCRIPTION
The M37702M2LXXXGP is a single-chip 16-bit microcomputer
designed with high-performance CMOS silicon gate technology.
This is housed in a small 80-pin plastic molded QFP. This singlechip microcomputer has a large 16 M bytes address space, three
instruction queue buffers, and two data buffers for high-speed instruction execution. The CPU is a 16-bit parallel processor that
can also be switched to perform 8-bit parallel processing. This
microcomputer is suitable for communication, office, business and
industrial equipment controller that require high-speed processing
of large data.
The strong points of the M37702M2LXXXGP, M37702S1LGP,
M37702M2LXXXHP and M37702S1LHP are the low supply voltage
and small package.
The differences between M37702M2LXXXGP, M37702S1LGP,
M37702M2LXXXHP and M37702S1LHP are the ROM size and
the package as shown below. Therefore, the following descriptions
will be for the M37702M2LXXXGP unless otherwise noted.

Functions
Supply 2.7 – 5.5 V to VCC and 0 V to VSS.
This pin controls the processor mode. Connect to VSS for single-chip mode, and
CC for external ROM types.
to V
To enter the reset state, this pin must be kept at a “L” condition which should be
maintained for the required time.
These are I/O pins of internal clock generating circuit. Connect a ceramic or quartz
IN
and X
OUT
crystal resonator between X
source should be connected to the X
. When an external clock is used, the clock
IN
pin and the X
OUT
pin should be left open.
Data or instruction read and data write are performed when output from this pin
is “L”.
In memory expansion mode or microprocessor mode, this pin determines
whether the external data bus is 8-bit width or 16-bit width. The width is 16 bits
when “L” signal inputs and 8 bits when “H” signal inputs.
Power supply for the A-D converter. Connect AV
CC to VCC and AVSS to VSS
externally.
This is reference voltage input pin for the A-D converter.
In single-chip mode, port P0 becomes an 8-bit I/O port. An I/O direction register
is available so that each pin can be programmed for input or output. These ports
are in input mode when reset.
Address (A7 – A0) is output in memory expansion mode or microprocessor mode.
In single-chip mode, these pins have the same functions as port P0. When the
BYTE pin is set to “L” in memory expansion mode or microprocessor mode and
external data bus is 16-bit width, high-order data (D15 – D8) is input or output
__
when E output is “L” and an address (A15 – A8) is output when E output is “H”.
If the BYTE pin is “H” that is an external data bus is 8-bit width, only address
(A15 – A8) is output.
In single-chip mode, these pins have the same functions as port P0. In memory
expansion mode or microprocessor mode low-order data (D
output when E output is “L” and an address (A23 – A16) is output when E output
__
7 – D0) is input or
is “H”.
In single-chip mode, these pins have the same functions as port P0. In memory
expansion mode or microprocessor mode, R/W, BHE, ALE and HLDA signals
__ ____
_____
are output.
In single-chip mode, these pins have the same functions as port P0. In memory
expansion mode or microprocessor mode, P40 and P41 become HOLD and RDY
_____
____
input pin respectively. Functions of other pins are the same as in single-chip
mode. In single-chip mode or memory expansion mode, port P42 can be programmed for φ
mode. P4
1 output pin divided the clock to XIN pin by 2. In microprocessor
2 always has the function as φ1 output pin.
In addition to having the same functions as port P0 in single-chip mode, these
pins also function as I/O pins for timer A0, timer A1, timer A2 and timer A3.
In addition to having the same functions as port P0 in single-chip mode, these
pins also function as I/O pins for timer A4, external interrupt input INT0, INT1 and
____
INT2 pins, and input pins for timer B0, timer B1 and timer B2.
____ ____
In addition to having the same functions as port P0 in single-chip mode, these
pins also function as analog input AN
0 – AN7 input pins. P77 also has an A-D
conversion trigger input function.
In addition to having the same functions as port P0 in single-chip mode, these
pins also function as RXD, TXD, CLK, CTS/RTS pins for UART 0 and UART 1.

The M37702M2LXXXGP has the same functions as the
M37702M2BXXXFP except for the reset circuit.
Refer to the section on the M37702M2BXXXFP.
RESET CIRCUIT
Reset occurs when the RESET pin is returned to “H” level after
holding it at “L” level when the power voltage is at 2.7 – 5.5 V. Program execution starts at the address formed by setting the
address pins A
FFFF
