The IA82510 is a "plug-and-play" drop-in replacement for the original IC. innovASIC produces replacement ICs
using its MILESTM, or Managed IC Lifetime Extension System, cloning technology. This technology produces
replacement ICs far more complex than "emulation" while ensuring they are compatible with the original IC.
MILESTM captures the design of a clone so it can be produced even as silicon technology advances. MILESTM
also verifies the clone against the original IC so that even the "undocumented features" are duplicated. This data
sheet documents all necessary engineering information about the IA82510 including functional and I/O
descriptions, electrical characteristics, and applicable timing.

AC/DC Parameters
Absolute maximum ratings:
Supply Voltage, VDD…………………………….…-0.3V to +6.0V
Input Voltage, VIN…………………………………-0.3V to VDD +0.3V
Input Pin Current, IIN…………………………….±10 mA, 25° C
Operating Temperature Range……………………..-40° C to +85°C
Ambient temperature under bias........................……..-40°C to +85°C *
Storage temperature.......................................…........….- 55°C to +150°C
Lead Temperature………………………………….+300°C, 10 sec.
Power dissipation..............................................................155 mW, 125°C, 25MHz, 15% Toggle
Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. Operating the device beyond the conditions
indicated in the “recommended operating conditions” section is not recommended. Operation at the “absolute maximum ratings” may adversely affect
device reliability.
* The input and output parametric values in section VII-B, parts 1, 2, and 3, are directly related to ambient
temperature and DC supply voltage. A temperature or supply voltage range other than those specified in the
Operating Conditions above will affect these values and part performance is not guaranteed by innovASIC.

ERRATA
PLEASE NOTE:
When using the -01 version of the IA82510, please refer to the errata section,
"Production Version -01, Errata".
When using the -00 version of the IA82510, please refer to the errata section,
"Production Version -00, Errata".
Production Version -01, Errata
The following errata are known problems with the -01 version of the IA82510. This is inclusive of
all package types and environment grades. A workaround to the identified problem has been
provided where possible. ALL ERRATA LISTED IN PRODUCTION VERION -00 HAVE
BEEN FIXED IN THIS VERSION OF THE DEVICE UNLESS OTHERWISE NOTED.
-00 Errata not fixed in this Production Version:
1. Problem: Device does not operate at 8 MHz in divide-by-one mode
Analysis: System testing revealed this operational deficiency.
Workaround: Switch to divide-by-two mode using 2X clock input
New Errata for Production Version -01:
2. Problem: RX FIFO locks up unexpectedly just after configuration and before starting
reception.
Analysis: An RCM command is executed with data of xB8. This is an “enable RX”, “flush RX
machine”, “flush RX FIFO”, and “lock RX FIFO” command done in a single instruction. The
“flush RX machine” should unlock the RX FIFO, creating a conflict with the simultaneous
“lock RX FIFO” command. The original Intel device apparently ignores or gives the “lock RX
FIFO” command lower priority in this case. The IA82510 has this priority reversed.
Apparently, the application software in this case expected the “lock RX FIFO” command to
fail.
Workaround: Do not execute a “flush RX FIFO” and “lock RX FIFO” command
simultaneously. Break up into separate RCM commands.
3. Problem: Unreliable transmits in AUTO TX mode.
Analysis: Many systems use the RTS output to activate the line transceiver. When the
Transmit Mode field in the TMD register is set to semi-auto or automatic mode, RTS is
controlled by the TX state machine. On the first character, RTS asserts at the same time as
the start bit on the TXD output, whereas the original Intel device asserts RTS a full bit time
before assertion of the start bit on TXD. At full temperature range, the width of the start bit
