11 TCI6630K2L Peripheral Information and Electrical Specifications
This chapter covers the various peripherals on the TCI6630K2L device. Peripheral-specific information,
timing diagrams, electrical specifications, and register memory maps are described in this chapter.
11.1 Recommended Clock and Control Signal Transition Behavior
All clocks and control signals must transition between V_IH and V_IL (or between V_IL and V_IH) in a monotonic
manner.
11.2 Power Supplies
The following sections describe the proper power-supply sequencing and timing needed to properly power
on the TCI6630K2L. The various power supply rails and their primary functions are listed in Table 11-1.

11.2.1 Power-Up Sequencing
This section defines the requirements for a power-up sequencing from a power-on reset condition. There
are two acceptable power sequences for the device.
The first sequence stipulates the core voltages starting before the IO voltages as shown below.
1. CVDD
2. CVDD1, VDDAHV, AVDDAx, DVDD18
3. DVDDR
4. VDDALV, VDDUSB, VP, VPTX
5. DVDD33, VPH
The second sequence provides compatibility with other TI processors with the IO voltage starting before
the core voltages as shown below.
1. VDDAHV, AVDDAx, DVDD18
2. CVDD
3. CVDD1
4. DVDDR
5. VDDALV, VDDUSB, VP, VPTX
6. DVDD33, VPH
