TS128M~2GSDM Description Transcend miniSD Card is non-volatile, which means no external power is required to retain the information stored on it. Besides, it is also a solid-state device that without moving parts to skip or break down. Transcend miniSD Card can offer an incredible combination of fast data transfer, great flexibility, excellent security and incredibly small size. miniSD Memory Card Features • ROHS compliant product • Operating Voltage: 2.7 ~ 3.6V • Operating Temperature: -25 ~ 85°C • Insertion/removal durability: 10,000 cycles • Fully compatible with SD card spec. v1.1 • Comply with SD Association File System Specification • Forward compatibility to MultiMediaCard Version 2.11 • Supports Copy Protection for Recorded Media(CPRM) for music and other commercial media • Form Factor: 21.5mm x 20mm x 1.4mm Placement 9 1 2 3 10 11 4 5 6 7 8 Pin Definition 2GB Front Back Pin Name Type Description No. 1 CD/DAT3 I/O/PP3 Card Detect/Data Line [Bit3] 2 3 4 5 6 7 8 9 10 11 CMD VSS1 VDD CLK VSS2 DAT0 DAT1 DAT2 NC4 NC4 PP S S I S Command/Response Supply voltage ground Supply voltage Clock Supply voltage ground I/O/PP Data Line [Bit0] I/O/PP Data Line [Bit1] I/O/PP Data Line [Bit2] I/O/PP For Future Use I/O/PP For Future Use Transcend Information Inc. 1 TS128M~2GSDM Architecture miniSD Memory Card Transcend Information Inc. 2 TS128M~2GSDM Bus Operating Conditions • General Parameter Peak voltage on all lines All Inputs Input Leakage Current All Outputs Output Leakage Current -10 10 µA -10 10 µA miniSD Memory Card Symbol Min. -0.3 Max.

The current consumption of any card during the power-up procedure must not exceed 10 mA. • Bus Signal Line Load The total capacitance CL the CLK line of the SD Memory Card bus is the sum of the bus master capacitance CHOST, the bus capacitance CBUS itself and the capacitance CCARD of each card connected to this line: CL = CHOST + CBUS + Ν*CCARD Where N is the number of connected cards. Requiring the sum of the host and bus capacitances not to exceed 30 pF for up to 10 cards, and 40 pF for up to 30 cards, the following values must not be exceeded: Parameter Bus signal line capacitance Single card capacitance Maximum signal line inductance Pull-up resistance inside card (pin1) Symbol CL CCARD RDAT3 Min.
