Description of Changes

Rev. 1

4/2008

Initial release

Rev. 2

12/2008

• Maximum amount of flash increased from 1 MB to 1.5 MB. Flash memory type has

changed. Rev. 1 and later devices use LC flash instead of FL flash.

• Additional packages offered—now includes100 LQFP and 176 LQFP. Please note that

the pinouts can vary for the same package depending on the amount of flash memory

included in the device.

• Device comparison table added.

• Feature details section added

• Signal summary table expanded. Now includes PCR register numbers and signal

selection values and pin numbers for all production packages.

• Electrical characteristics updated.

• DSPI timing data added for 40 MHz and 60 MHz.

• Thermal characteristics data updated. Data added for 100- and 176-pin packages.

• DSPI LVDS pad specifications added.

Rev. 3

2/2009

Electrical characteristics updated

• Flash memory electrical characteristics updated for LC flash

• Power management control (PMC) and Power on Reset (POR) specifications updated

• EMI characteristics data added

• Maximum ratings updated

• I/O pad current specifications updated

• I/O Pad VRC33 current specifications added

• Temperature sensor electrical characteristics added

Pad type added to “Voltage” column of signal summary table

Many signal names have changed to make them more understandable

• DSPI: PCS_C[n] is now DSPI_C_PCS[n]; SOUT_C is now DSPI_C_SOUT, SIN_C is

now DSPI_C_SIN, and SCK_C is now DSPI_C_SCK

• CAN: CNTXB is now CAN_B_TX and CNRXB is now CAN_B_RC

• SCI: RXDB is now SCI_B_RX and TXDB is now SCI_B_TX

• In cases where multiple instances of the same IP block is incorporated into the device,

e.g., 2 SCI blocks, the above nomenclature applies to all blocks

“No connect” pins on pinouts clarified

• Pins labelled “NIC” have no internal connection and should be tied to ground

• Pins labelled “NC” are not functional pins but may be connected to internal circuits

They are to be left floating

Some of the longer multiplexed signal names appearing on pinouts have been moved to

the inside of the package body to avoid having to use smaller fonts

Orderable parts table updated

Part number decoder added
