Universal Communications Controller
Data Sheet

1. Introduction
The IA80C152 is a ―plug-and-play‖ drop-in replacement for the original Intel 80C152.
Innovasic produces replacement ICs using its MILES, 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. MILES captures the design
of a clone so it can be produced even as silicon technology advances. MILES also verifies the
clone against the original IC so that even the ―undocumented features‖ are duplicated. This data
sheet presents engineering information about the IA80C152 including functional and I/O
descriptions, electrical characteristics, and applicable timing.
1.1 General Description
The IA80C152 is a Universal Communications Controller (UCC) that is pin-for-pin compatible
with the Intel 80C152. This version of the UCC is a ROM-less version. The ROM version is
identified as the 83C152 and can be easily derived from the 80C152 using a customer furnished
ROM program. The IA80C152 can be programmed with the same software development tools
and can transmit and receive using the same communication protocols as the Intel 80C152
making the IA80C152 a drop-in replacement.
Table 1 below cross-references IA80C152 versions with protocol, package, and I/O Port
capability. Pinout diagrams are provided in Figures 1, 2, and 3.

The only difference between The Innovasic IA80C152 and the Intel 80C152 is that all protocols
are available in all IC versions. Originally, the Intel 80C152 JC and JD versions were limited to
SDLC/HDLC only. Also, Innovasic will support a ROM version (83152) in any of the JA, JB,
JC, or JD versions.
Note: If you are using the IA80C152JB/JD in a system that originally used an Intel 80C152JA/JC,
please note that the EBEN pin on the Innovasic part has an internal pull down, so it is recommended
that you do not connect that pin (NC) on your board for proper functionality. In addition, the two
ports that are unused on the JA/JC device (Ports 5 and 6) have internal pullups on the Innovasic
device, so it is recommended that you do not connect (NC) these pins.
