The IAH8/3048 is code compatible with the original Hitachi
H8/300H family of
microcontrollers, with additional security enhancements designed into the device. innov
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 Advanced Information Sheet contains preliminary information for this the IAH8/3048. The
complete data sheet which documents all necessary engineering information about the IAH8/3048
including functional and I/O descriptions, electrical characteristics, and applicable timing will be
available when the device nears completion.

The IAH8/3048 Security-Enhanced Microcontroller is the ideal solution for many embedded
applications, combining the flexibility of the Hitachi
H8/300H family of microcontrollers with
the power of additional on-chip features. This combination allows the development of more
complex embedded applications than is possible with the H8 alone. It also eases the
implementation of more robust security features that are required of products today.
The IAH8/3048 provides an upward compatibility path for Hitachi
H8/300H users who need
higher performance and on-chip security features. The IAH8/3048 is code compatible with the
H8/300H family of microcontrollers and is pin compatible with the 100-pin QFP of the H8/3048
microcontroller series. Code development for the IAH8/3048 utilizes standard H8/300H
software development tools, including compilers, assemblers, and linkers.

The IAH8/3048 offers all of the standard features of the advanced H8/3048 microcontroller
series with a nearly doubled operating frequency of 30 MHz. InnovASIC has also added new
security-related features to make the IAH8/3048 a compelling choice for embedded applications
that require higher levels of integrity, authenticity and data protection without loss of performance.
These security features include an extremely flexible 128 Kbytes of nonvolatile memory in two
independent partitions. The NV also has read-out protection and locking mechanisms to protect
vital data. Additional security enhancements include a high quality physical random number
generator and a fast 32x32 multiply with 64-bit result executed as an additional instruction. The
IAH8/3048 also facilitates PKI and other challenge-response protocols.
Ordering Information

The IAH8/3048 is scheduled for production in Q4 2001. Additional versions, including a 3.3V
version, are scheduled for release in 2002.
