111 / 251 page  Note The UFS interface electrical characteristics are compliant with MIPI M-PHY Specification v3.1, February 17, 2014. Note The DP interface electrical characteristics are compliant with the VESA DisplayPort (DP) Standard v 1.4 February 23, 2016. Note The eDP interface electrical characteristics are compliant with the VESA Embedded DisplayPort (eDP) Standard v1.4b October 23, 2015. 7.6.13 DDR0 Electrical Characteristics Note The DDR interface is compatible with JESD209-4B standard compliant LPDDR4 SDRAM devices. 7.7 VPP Specifications for One-Time Programmable (OTP) eFuses This section specifies the operating conditions required for programming the OTP eFuses and is applicable only for High-Security Devices. 7.7.1 Recommended Operating Conditions for OTP eFuse Programming over operating free-air temperature range (unless otherwise noted) PARAMETER DESCRIPTION MIN NOM MAX UNIT VDD_CORE Supply voltage range for the core domain during OTP operation; OPP NOM (BOOT) See Recommended Operating Conditions V VDD_MCU Supply voltage range for the core domain during OTP operation; OPP NOM (BOOT) See Recommended Operating Conditions V VPP_CORE Supply voltage range for the eFuse ROM domain during normal operation N/A(2) Supply voltage range for the eFuse ROM domain during OTP programming(1) 1.71 1.8 1.89 V VPP_MCU Supply voltage range for the eFuse ROM domain during normal operation N/A(2) Supply voltage range for the eFuse ROM domain during OTP programming(1) 1.71 1.8 1.89 V (1) Supply voltage range includes DC errors and peak-to-peak noise. TI power management solutions TLV70018-Q1 from the TLV707x family meet the supply voltage range needed for VPP_CORE and VPP_MCU. (2) N/A stands for Not Applicable. 7.7.2 Hardware Requirements The following hardware requirements must be met when programming keys in the OTP eFuses: • The VPP_CORE and VPP_MCU power supplies must be disabled when not programming OTP registers. • The VPP_CORE and VPP_MCU power supplies must be ramped up after the proper device power-up sequence (for more details, see Power Supply Sequencing). 7.7.3 Programming Sequence Programming sequence for OTP eFuses: www.ti.com TDA4VE-Q1, TDA4AL-Q1, TDA4VL-Q1 SPRSP62 – DECEMBER 2022 Copyright © 2023 Texas Instruments Incorporated Submit Document Feedback 111 Product Folder Links: TDA4VE-Q1 TDA4AL-Q1 TDA4VL-Q1 |
