FAQ
What is the maximum operating frequency of the TMS320DM6435ZDU7?
The TMS320DM6435ZDU7 operates at a maximum frequency of 700 MHz, corresponding to the "-7" speed grade suffix. This enables 5600 million instructions per second (MIPS) and 5600 million multiply-accumulates per second (MMACS), verified under 1.05-V core voltage and specified thermal conditions per SPRS344C datasheet Section 2.1.
Does the TMS320DM6435ZDU7 support DDR2 memory interfacing?
Yes, the TMS320DM6435ZDU7 integrates a 32-bit DDR2 SDRAM memory controller supporting data rates up to 333 MHz (DDR2-400), with 1.8-V I/O compatibility and 256-MB address space. It includes DQS strobes, ODT control, and programmable timing parameters for reliable interface to standard DDR2 components.
What video interfaces does the TMS320DM6435ZDU7 VPFE support?
The TMS320DM6435ZDU7 Video Processing Front-End (VPFE) supports BT.601/BT.656 digital YCbCr 4:2:2 (8-/16-bit), raw Bayer pattern from CMOS/CCD sensors, and glueless interfaces to common video decoders. It includes CCDC, Preview Engine, Histogram, H3A, and Resizer modules for full pipeline acceleration.
Is the TMS320DM6435ZDU7 pin-compatible with other DM643x devices?
No, the TMS320DM6435ZDU7 uses a 376-pin ZDU BGA package (1.0-mm pitch), which is not pin-compatible with the 361-pin ZWT package (0.8-mm pitch) used by TMS320DM6435ZWT7 or TMS320DM6437ZWT7. Pin assignments, ball pitch, and thermal pad configuration differ significantly between ZDU and ZWT variants.
What power supply voltages does the TMS320DM6435ZDU7 require?
The TMS320DM6435ZDU7 requires two primary supplies: 1.05 V for the core (VDD_CORE) and 1.8 V for I/O (VDD_IO), as specified in Section 2.1 and Section 6.3 of the SPRS344C datasheet. The 1.05-V core rail powers the C64x+™ CPU and L1/L2 memory; the 1.8-V I/O rail powers DDR2, VPFE, McASP0, and GPIO interfaces.
