NVT4858 SD, SDIO, mini SD, micro SD and SIM card voltage level translator with EMI filter and ESD protection Rev. 2.1 12 November 2021 Product data sheet 1 General description The device is an SD 3.0-compliant bidirectional dual voltage level translator with auto- direction control. It is designed to interface between a memory or SIM card operating between 1.62 V to 3.6 V signal levels and a host with a supply voltage of 1.08 V to 1.98 V. The device supports SD 3.0 SDR104, SDR50, DDR50, SDR25, SDR12 and SD 2.0 High- Speed (50 MHz) and Default-Speed (25 MHz) modes. The device has an auto-enable/ disable function connected to the V supply pin, built-in EMI filters and robust ESD CCB protections (IEC 61000-4-2, level 4) on V or any of the card side pins. External ESD CCB diodes are not required. This device also supports SIM card voltage level translator using CLK and two of the data lines for SD and SIM card combo sockets. 2 Features and benefits Supports up to 208 MHz clock rate SD 3.0 specification-compliant voltage translation to support SDR104, SDR50, DDR50, SDR25, SDR12, High-Speed and Default-Speed modes Compliant with all ETSI, IMT-2000 and ISO-7816 SIM/Smart Card interface requirements Support SD/SIM card supply voltages with range of 1.62 V to 3.6 V Host microcontroller operating voltage range: 1.08 V to 1.98 V Feedback channel for clock synchronization Low power consumption by push-pull output stage with break-before-make architecture Automatic enable and disable through V CCB Integrated pull-up and pull-down resistors: no external resistors required Integrated EMI filters suppress higher harmonics of digital I/Os Integrated 8 kV ESD protection according to IEC 61000-4-2, level 4 on on V or any CCB of the card side pins. External ESD diodes are not required. Level shifting buffers keep ESD stress away from the host (zero-clamping concept) Available in XQFN16 with 0.4 mm pitch and WLCSP16 with 0.35 mm pitch 3 Applications Smart phones Mobile handsets Digital cameras Tablet PCs Laptop computers SD, MMC or microSD card readersNXP Semiconductors NVT4858 SD, SDIO, mini SD, micro SD and SIM card voltage level translator with EMI filter and ESD protection 4 Ordering information Table 1.Ordering information Type number Topside mark Package Name Description Version NVT4858UK N858 WLCSP16 wafer level chip scale package 16 bumps (4 x 4), body SOT2127-1 1.41 x 1.41 x 0.525 mm, 0.35 mm pitch NVT4858HK N58 XQFN16 plastic, extremely thin quad flat package no leads 16 SOT1161-2 terminals 2.6 mm x 1.8 mm x 0.50 mm body with 0.4 mm pitch 4.1 Ordering options Table 2.Ordering options Type number Orderable part Package Packing method Minimum Temperature number order quantity 1 NVT4858UK NVT4858UKZ WLCSP16 REEL 7 Q1/T1 3000 T = -40 C to +85 C amb 2 3 NVT4858HK NVT4858HKZ XQFN16 REEL 7 Q1/T1 SSB 4000 T = -40 C to +85 C amb 1 Find packing information at www.nxp.com/docs/en/packing/SOT2127-1 012.pdf 2 This packing method uses a Static Shielding Bag (SSB) solution.
