Power for TMS320C5514/15 April 7, 2010 SLVA400B (1) C5514/15 Power Spec Table Pin Name Voltage (V) Max Current 6 (mA) Tolerance Sequencing Order 1 LDOI 3, 4 1.8 - 3.6 70 2 Comments Supplying ANA LDO (supplies VDDA_ANA and VDDA_PLL) and USB LDO (supplies USB_VDD1P3 and USB_VDDA1P3) must make proper external connections Typical Core Power Consumption: Core CVDD1,5 1.05 / 1.30 500 -5%, +10% CVDDRTC1,5 1.05 – 1.30 0.1 -5%, +10% DVDDIO, DVDDRTC 1.8 / 2.5 / 2.8 / 3.3 300 ±10% DVDDEMIF 1.8 / 2.5 / 2.8 / 3.3 245 ±10% 3.3V 55 ±10% USB_VDDOSC, USB_VDDA3P3, USB_VDDPLL - 0.22mW/MHz for 75% DMAC + 25% NOP (CVDD =1.3V @ 100MHz, Room Temp) - 0.14mW/MHz for 75% DMAC + 25% NOP (CVDD =1.05V @ 100MHz, Room Temp) NOTES: 1) CVDD can be 1.05V or 1.30V for ≤ 60MHz or 75MHz and 1.30V for operating ≤ 100MHz or 120MHz (depending device speed grade option). CVDDRTC can be 1.05V – 1.30V regardless of CVDD and regardless of operating frequency. CVDD and CVDDRTC are not required to be powered from the same source. For lowest standby power, CVDD power can be shut off while other supplies remain powered. 2) Power Supply Sequencing: No sequencing is required (for further details, see section 5.3.1 of the data sheet) 3) If GPAIN pins are used as general purpose outputs, the internal ANA_LDO must not be used as the max current capability of ANA_LDO can be exceeded. In this case use an external regulator to supply VDDA_ANA. 4) If boot from USB is required an external regulator must be used instead of the internal USB_LDO. See the Silicon Errata document SPRZ308 for more details 5) For lowest BOM cost solution the internal DSP_LDO can be used to supply CVDD, with LDOI then having a max of 570mA. When using DSP_LDO to power CVDD, CVDDRTC must be powered by a separate external source. See the C5514/15 data sheets for more detail. 6) This column shows the maximum design current of each power domain. See the C5515/14 data sheets for actual current consumptions of some usage cases. See the data in the “Comments” column above.
