4 Peripheral and Electrical Specifications

4.1 Electrical Specifications

This section provides the absolute maximum ratings and the recommended operating conditions for the TMS320C672x DSP.

All electrical and switching characteristics in this data manual are valid over the recommended operating conditions unless otherwise specified.

4.2 Absolute Maximum Ratings(1)(2)

Over Operating Case Temperature Range (Unless Otherwise Noted)

(1)Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2)All voltage values are with referenced to VSS unless otherwise specified.

(3)If OSCVDD and OSCVSS pins are used as filter pins for reduced oscillator jitter, they should not be connected to CVDD and VSS externally.

4.3 Recommended Operating Conditions(1)

IDD2V	CVDD Supply(1)	GDH/ZDH, CVDD = 1.2 V,		658
		CPU clock = 300 MHz				mA
		RFP, CVDD = 1.2 V,		555		mA
		RFP, CVDD = 1.2 V,		555

IDD3V	DVDD Supply(1)	GDH/ZDH, DVDD = 3.3 V,		76
		32-bit EMIF speed = 100 MHz				mA
		RFP, DVDD = 3.3 V,		58		mA
		RFP, DVDD = 3.3 V,		58

16-bit EMIF speed = 100 MHz

(1)Assumes the following conditions: 25°C case temperature; 60% CPU utilization; EMIF at 50% utilization (100 MHz), 50% writes, (32 bits for GDH/ZDH, 16 bits for RFP), 50% bit switching; two 10-MHz SPI at 100% utilization, 50% bit switching.

The actual current draw is highly application-dependent. For more details on core and I/O activity, refer to the TMS320C672x Power Consumption Summary Application Report (literature number SPRAAA4).
