MOS INTEGRATED CIRCUIT
µPD98402A
LOCAL ATM SONET FRAMER
The µPD98402A is one of the ATM-LAN LSIs and incorporates the TC sublayer function in the SONET/SDHbased physical layer of the ATM protocol. The main functions of the µPD98402A include a transmit function for
mapping ATM cells received from the ATM layer onto the payload block of the SONET STS-3c/SDH STM-1 frame
and sending them to PMD (Physical Media Dependent) in the physical layer, and a receive function for separating
the overhead block and ATM cells from the data string received from the PMD sublayer and sending the ATM cells
to the ATM layer.
Futhermore, the µPD98402A is compliant with the ATM Forum UNI Recommendations.
FEATURES
• Provision of TC sublayer function of ATM protocol physical layer
• Support of SONET STS-3c frame/SDH STM-1 frame format
• Provision of stop mode for cell scramble/descramble and frame scramble/descramble
• Disposal/transitory selection of unassigned cells is possible.
• Compliant with UTOPIA interface
• Incorporation of internal loopback function at PMD and ATM layer turns
• PMD interface
155.52 Mbps serial interface
19.44 MHz parallel interface
• Provided with registers for writing/reading overhead information
SOH (section overhead): C1 (1st to 3rd) bytes, F1 byte
LOH (line overhead): K2 byte
POH (pass overhead): F2 byte, C2 byte
• CMOS process
• +5 V single power supply

4. RECOMMENDED SOLDERING CONDITIONS
For the µPD98402A, soldering must be performed under the following conditions.
For details of recommended conditions for surface mounting, refer to information document “Semiconductor
Device Mounting Technology Manual” (IEI-1207).
For other soldering methods, please consult with NEC sales personnel.

Soldering Method
Soldering Conditions
Symbol
Infrared reflow
Package peak temperature: 235 °C, time: 30 sec. max. (over 210 °C), count:
twice or less, restriction days: 3Note (after that, 125 °C pre-baking for 20 hours
is necessary)
Precautions:
(1) Reflow a second time should be started when the device temperature has
returned to its normal state after the first reflow.
(2) Avoid flux cleaning with water after the first reflow.
IR35-203-2
Pin partial heating
Pin temperature: 300 °C max., time: 3 seconds max. (per side)
Note
This means the number of days after unpacking the dry pack. Storage conditions are 25 °C and 65 % RM
max.

representative.
No part of this document may be copied or reproduced in any form or by any means without the prior written
consent of NEC Corporation. NEC Corporation assumes no responsibility for any errors which may appear in this
document.
NEC Corporation does not assume any liability for infringement of patents, copyrights or other intellectual
property rights of third parties by or arising from use of a device described herein or any other liability arising
from use of such device. No license, either express, implied or otherwise, is granted under any patents,
copyrights or other intellectual property rights of NEC Corporation or others.
While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor devices,
the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or
property arising from a defect in an NEC semiconductor device, customer must incorporate sufficient safety
measures in its design, such as redundancy, fire-containment, and anti-failure features.
NEC devices are classified into the following three quality grades:
“Standard“, “Special“, and “Specific“. The Specific quality grade applies only to devices developed based on
a customer designated “quality assurance program“ for a specific application. The recommended applications
of a device depend on its quality grade, as indicated below. Customers must check the quality grade of each
device before using it in a particular application.
Standard: Computers, office equipment, communications equipment, test and measurement equipment,
audio and visual equipment, home electronic appliances, machine tools, personal electronic
equipment and industrial robots
Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster
systems, anti-crime systems, safety equipment and medical equipment (not specifically designed
for life support)
Specific: Aircrafts, aerospace equipment, submersible repeaters, nuclear reactor control systems, life
support systems or medical equipment for life support, etc.
The quality grade of NEC devices in “Standard“ unless otherwise specified in NEC's Data Sheets or Data Books.
If customers intend to use NEC devices for applications other than those specified for Standard quality grade,
they should contact NEC Sales Representative in advance.
Anti-radioactive design is not implemented in this product.
