Appendix B Rabbit 3000 Revisions
Rabbit 3000 chips identified by UL2T for the LQFP package and DZ2J for the TFBGA
package are RoHS-compliant. The UL2T and DZ2J RoHS versions were introduced in
mid-2007, and the IL2T and IZ2T non-RoHS versions are no longer avaialble.
(j) The low-power capability of the processor was further expanded with the addi-
(k) The PWM outputs can now trigger a PWM interrupt each cycle or every
(l) The quadrature decoder hardware can be configured to use a 10-bit counter in
(m)An option was added to alternatively multiplex PWM outputs, slave chip select

NOTE: Based on this modification, a new low-power oscillator circuit is recommended
for use with Rabbit 3000A-based systems. Please refer to TN235, External 32.768 kHz
Oscillator Circuits, for more information on the circuit.
