The IA70CX0 is a form, fit, and function replacement for the original Texas Instruments TMS70CX0
CMOS 8-Bit Microcontroller. The IA70CX0 incorporates a CPU, memory, bit I/ O, timer, interrupts
and external bus interface logic on a single chip. Typical applications for the IA70CX0 microcontroller
include industrial, consumer, computer, telecom and automotive applications. InnovASIC‟s version of
the microcontroller includes all the features listed above and is “plug and play” with the original Texas
Instruments device.
InnovASIC produces replacement ICs using its MILES^TM, 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^TM captures the design of a clone so it
can be produced even as silicon technology advances. MILES^TM also verifies the clone against the
original IC so that even the "undocumented features" are duplicated.
