GMS81508B/16B/24B
GMS82512/16/24
CMOS SINGLE-CHIP 8-BIT MICROCONTROLLER
WITH A/D CONVERTER
1. OVERVIEW
1.1 Description
The GMS81508B/16B/24B are advanced CMOS 8-bit microcontrollers with 8K/16K/24K bytes of ROM and 64pin package.
And the GMS82512/16/24 are the same except for 12K/16K/24K bytes of ROM and 42pin package. The GMS825xx is a
cut-down product of GMS815xxB microcontroller, that is, the function and package are reduced. These are powerful micro-
controllers which provide a highly flexible and cost effective solution to many general application. These includes several
peripheral functions such as Timer, A/D converter, Programmable buzzer driver, Serial I/O communication(GMS815xxB
only), Pulse Width Modulation function( GMS815xxB only), etc. The RAM, ROM, and I/O are placed on the same memory
map in addition to simple instruction set. Also, they support power saving mode to reduce power consumption.
The GMS815xxB is functionally 100% compatible with earier GMS81508/16 or GMS81508A/16A, and has better charac-
teristics such as strong EMS, wide operating voltage, temperature, frequency and fast programming time for the OTP.

• Available 16K, 24K bytes OTP version
(Available 24K bytes in GMS825xx)
1.3 Development Tools
The GMS815xxB and GMS825xx are supported by a full-
featured macro assembler, an in-circuit emulator
CHOICE-Dr.TM and OTP programmers. There are two
different type programmers such as single type, gang
type(Stand-alone gang4). For more detail, Refer to “22.
OTP PROGRAMMING” on page 76. Macro assembler
operates under the MS-Windows 95/98TM.

5. PIN FUNCTION
VDD: Supply voltage.
VSS: Circuit ground.
TEST: Used for Test Mode. For normal operation, it
should be connected to VDD.
RESET: Reset the MCU.
XIN: Input to the inverting oscillator amplifier and input to
the internal main clock operating circuit.
XOUT: Output from the inverting oscillator amplifier.
R00~R07: R0 is an 8-bit CMOS bidirectional I/O port. R0
pins 1 or 0 written to the Port Direction Register can be
used as outputs or inputs.
R10~R17: R1 is an 8-bit CMOS bidirectional I/O port. R1
pins 1 or 0 written to the Port Direction Register can be
used as outputs or inputs.
These pins are NOT served on GMS825xx.
R20~R27: R2 is an 8-bit CMOS bidirectional I/O port. R2
pins 1 or 0 written to the Port Direction Register can be
used as outputs or inputs.
R30~R37: R3 is an 8-bit CMOS bidirectional I/O port. R3
pins 1 or 0 written to the Port Direction Register can be
used as outputs or inputs.
R40~R47: R4 is an 8-bit CMOS bidirectional I/O port. R4
pins 1 or 0 written to the Port Direction Register can be
used as outputs or inputs.
R45, R46, R47 are NOT served on GMS825xx.
In addition, R4 serves the functions of the various follow-
ing special features.
R50~R57: R5 is an 8-bit CMOS bidirectional I/O port. R5
pins 1 or 0 written to the Port Direction Register can be
used as outputs or inputs.
R50~R53, R56, R57 are NOT served on GMS825xx.
In addition, R5 serves the functions of the various follow-
ing special features.
R60~R67: R6 is an 8-bit CMOS bidirectional I/O port. R6
pins 1 or 0 written to the Port Direction Register can be
used as outputs or inputs.
R60~R63 are NOT served on GMS825xx.
In addition, R6 is shared with the ADC input.
Note: On the MDS(Choice-Dr, Jr), when the MCU is RE-
SET,R60 cannotbe used digitalinput port. Formoredetail,
refer to "9. I/O PORTS" on page 34.
AVDD: Supply voltage to the ladder resistor of ADC cir-
cuit. To enhance the resolution of analog to digital convert-
er, use independent power source as well as possible, other
than digital power source.
AVSS: ADC circuit ground.
AVSS is NOT served on GMS825xx but it is connected to
VSS internally.
