| TS128MRMMC Description TS128MRMMC is a 128MB Reduced-Sized MultiMediaCard(RS-MMC). It's a highly integrated with flash memory, and is accessed via a dedicated serial interface optimized for fast and reliable data transmission. It is designed to provide an inexpensive, mechanically robust storage medium in card form for multimedia consumer applications and mobile devices (handheld PCs, digital cameras, MP3 players, etc.) to store, copy, and move information like a small hard drive. RS-MMC Features * * * * * * * Storage Capacity: 128MB Operating Voltage: 2.7 ~ 3.6V Operating Temperature: -25C ~ 85C Fully compatible with MultiMediaCard system specification version 3.x Embedded data error correction Low power consumption Form Factor: 24mm x 18mm x 1.4mm Placement RS-MMC Front Pin Definition Back MMC Mode Pin No. 1 2 3 4 5 6 7 SPI Mode Description Reserved Name RSV CMD VSS1 VCC CLK VSS2 DAT Type NC I/O/PP/OD S S I S I/O/PP Name CS DI VSS VDD SCLK VSS2 DO Type I I/PP S S I S O/PP Description Chip select Data in GND VCC Clock GND Data out Command/Response Ground Power supply Clock Ground Data Transcend Information Inc. 1 TS128MRMMC Architecture RS-MMC VDD CMD OCR[31:0] CID[127:0] RCA[15:0] DSR[15:0] CSD[127:0] Memory core interface Reset Card interface controller Power Interface driver CLK DAT Reset on detection Memory Core Transcend Information Inc. 2 TS128MRMMC Temperature Characteristics Parameter Operating temperature RS-MMC Min -25 Max 85 Unit Electrical Characteristics * General Parameter Peak Voltage on all lines All Inputs Input Leakage Current All Outputs Output Leakage Current -10 10 uA -10 10 uA Min -0.5 Max 3.6 Unit V * Power Supply Voltage Parameter Supply Voltage Symbol Min. VDDH 2.7 Max. 3.6 Unit V Remark * Bus Signal Line Load The total capacitance CL of each line of the MultiMediaCard 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 + N*CCARD where N is the number of connected cards. Requiring the sum of the host and bus capacitance's 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 Pull-up resistance for CMD Pull-up resistance for DAT Bus signal line capacitance Bus signal line capacitance Single card capacitance Maximum signal line inductance Symbol RCMD RDAT CL CL CCARD Min 4.7 50 Max 100 100 250 100 7 16 Unit k k pF pF pF nH Remark To prevent bus floating To prevent bus floating fpp5 MHz, 30 cards fpp20 MHz, 10 cards fpp20 MHz Transcend Information Inc. 3 TS128MRMMC * Bus Signal Levels As the bus can be supplied with a variable supply voltage, all signal levels are related to the supply voltage.
