TS128MRMMC RS-MMC Description Features 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. • Storage Capacity: 128MB • Operating Voltage: 2.7 ~ 3.6V • Operating Temperature: -25°C ~ 85°C • 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 Back Pin Definition MMC Mode Pin No. SPI Mode Name Type Description Name Type Description 1 RSV NC Reserved CS I Chip select 2 CMD I/O/PP/OD Command/Response DI I/PP Data in 3 VSS1 S Ground VSS S GND 4 VCC S Power supply VDD S VCC 5 CLK I Clock SCLK I Clock 6 VSS2 S Ground VSS2 S GND 7 DAT I/O/PP Data DO O/PP Data out Transcend Information Inc. 1 TS128MRMMC RS-MMC Architecture VDD CMD Interface driver CLK DAT OCR[31:0] RCA[15:0] Reset DSR[15:0] CSD[127:0] Memory core interface Memory Core Transcend Information Inc. 2 Reset n o i t c e t e d n o r e w o P Card interface controller CID[127:0] TS128MRMMC RS-MMC Temperature Characteristics Parameter Min Max Unit Operating temperature -25 85 ℃ Electrical Characteristics • General Parameter Peak Voltage on all lines Min Max Unit -0.5 3.6 V -10 10 uA -10 10 uA All Inputs Input Leakage Current All Outputs Output Leakage Current • Power Supply Voltage Parameter Supply Voltage Symbol Min.
