began shipping in samples and very low volume to select customers having problems
with EMI in April, 2002. This part was phased out and will be replaced by the Rabbit
2000C for volume orders. This version has the clock spectrum spreader, but lacks the
early I/O enable, which results in tight specifications for memory I/O enable. The clock
doubler unit uses codes incompatible with earlier revisions. Furthermore, a problem
with LDIR/LDDR operation and Instruction/Data split was discovered. These problems
are all corrected in the Rabbit 2000C.
Rabbit Semiconductor products using the Rabbit 2000 chip will begin using the Rabbit
2000C chip in November, 2002. This version is the same as the Rabbit 2000B, except
that the early I/O enable is implemented and the clock doubler codes are compatible
with earlier versions. Although the LDIR/LDDR bug outlined in the Rabbit 2000B
description is fixed, a new bug related to block move operations and wait states was
discovered. This bug is automatically corrected by Dynamic C.
Rabbit 2000 chips identified by UQ5T on the package are RoHS-compliant. The UQ5T
RoHS versions were introduced in 2007, and both IQ5T and UQ5T versions are presently
avaialble.
