LC709004A
CMOS IC
I/O-Expander for Microcontroller
http://onsemi.com
Overview
The LC709004A is a peripheral IC dedicated for expanding the capability of the microcontroller (MCU) I/O ports. It
interfaces with the microcontroller through synchronous serial communication. Communication with the extended I/O
ports is accomplished through 16-bit parallel I/O. The extended port features include the capabilities to specify the I/O
direction on a bit basis, to specify the output type (CMOS or N-channel open drain), and to specify the I/O voltage
level on a port basis according to the power level of the peripheral equipment. These features make allow the
LC709004A to be used in a wide variety of applications.
Features
• 4-/5-wire synchronous serial transmission and reception, and 16-bit parallel I/O
• Wide operating voltage range (2.0V to 6.0V)
• Multifunction I/O ports
- I/O direction specification: Bit units
- CMOS or Nch-OD output type specification: Bit units
- Output voltage adjustment: Port (8 bits) units
• Output current: 12mA max. (capable of driving a green LED directly)
• Data transmission and reception: Can control reception of input data and transmission of output data in parallel.
• Cascaded configuration: Ports can be expanded in units of 16 bits × n (n is the number of LSI chips).
• Packaging from: MFP24S (300mil): lead-free type (discontinued)
MFP24SJ (300mil): lead-free type

(a) The case of using single voltage
(VDD= VDDP1)
Fig. 7
(b) The case of using variable voltage
In the case of using single voltage source as showing in the Fig.7 (a), you must connect a bypass capacitor (C1, about
0.1μF) between VDD and VSS. When connecting the capacitor (C1) and VDD-VSS, use a thick wire, and try to make
its length as short as possible: moreover, try to make the impedance of VDD-C1 and VSS-C1 equal.
In addition, when using several voltage sources as showing in the Fig.7 (b), it is suggested to connect the bypass
capacitor to each set of the voltage terminals.

RRES Note 6:
The values of CRES and RRES must be determined so
that a reset period of 1μs or longer is set up after the
RES operating voltage goes beyond its lower-limit value and
CRES
the reset can be released after the operating power
voltage is completely reached.
