TMS470R1VF478
16/32-BIT RISC FLASH MICROCONTROLLER
SPNS082D – JANUARY 2004 – REVISED JANUARY 2006
device characteristics
The TMS470R1VF478 device is a derivative of the F05 system emulation device SE470R1VB8AD. Table 1
identifies all the characteristics of the TMS470R1VF478 device except the SYSTEM and CPU, which are
generic. The COMMENTS column aids the user in software-programming and references device-specific
information.

COMMENTS FOR VF478
MEMORY
For the number of memory selects on this device, see the Memory Selection Assignment table (Table 2).
INTERNAL
MEMORY
288K-Byte flash
16K-Byte SRAM
Flash is pipeline-capable
The VF478 RAM is implemented in one 16K array selected by two memory-
select signals (see the Memory Selection Assignment table, Table 2).
PERIPHERALS
For the device-specific interrupt priority configurations, see the Interrupt Priority table (Table 6). And for the 1K peripheral address ranges and
their peripheral selects, see the VF478 Peripherals, System Module, and Flash Base Addresses table (Table 4).
CLOCK
FMPLL
FMPLL has no external loop filter pins.
GENERAL-PURPOSE
I/Os
3 I/O
1 Input only
Only four (4) external pins
SCI
1 (3-pin)
CAN
(HECC and/or SCC)
1 HECC, 1 SCC
High-end CAN controller and standard CAN controller
SPI
(5-pin, 4-pin or 3-pin)
2 (5-pin)
SPI1 and SPI2
MibSPI
(5-pin, 4-pin or 3-pin)
1 (5-pin)
HET with
XOR Share
32 I/O
The high-resolution (HR) SHARE feature allows even HR pins to share the next
higher odd HR pin structures. This HR sharing is independent of whether or not
the odd pin is available externally. If an odd pin is available externally and shared,
then the odd pin can only be used as a general-purpose I/O. For more information
on HR SHARE, see the TMS470R1x High-End Timer (HET) Reference Guide
(literature number SPNU199).
