TC6387XB

The TC6387XB automatically detects card types and power supply just by inserting SD memory card or SDIO Card. By using buffer-off function of #SUSPEND signal and gated clock control, power consumption of the system can be kept to a minimum which is a controller LSI for SD Memory Card/SDIO Card that comes in with interfaces for Standard Memory with 16 bits bus. Also, TC6387XB meets SD memory card physical layer specification and SD I/O card specification.

The specifications of TC6387XB can be summarized as (1)host bus interface, standard memory interface, 16 bit bus interface; (2)interruption support; (3)operating frequency 33MHz; (4)compatible w/ power supply control LSI MIC2563; (5)supports SD card 1 Slot; (6)meets SD memory card physical layer specification; (7)Ver.1.0, operating frequency (Max. 25MHz), multimedia card read/write capability, compatible w/ 3.3V, compatible w/ multi block write/read, not compatible w/ SPI mode, within 512byte*2 double buffers; (8)- meets SD I/O card specification Ver.1.0, operating frequency (Max. 25MHz), compatible w/ 3.3V, compatible w/ multi block write/read.

The absolute maximum ratings of TC6387XB are (1)VCC supply voltage range: -0.3 to 5.0V GND=0V(Note 1: VCC power supply); (2)Vin3 input voltage (3.3V): -0.3 to VCC+0.3V(GND=0V); (3)Vout output voltage: -0.3 to VCC+0.3V(GND=0V); (4)Tstg storage temperature range: -40 to 125(degree C)(Note: Absolute Maximum Ratings indicates that stress greater than the values described above might cause permanent damages to the devices and does not guarantee all the performances within Absolute Maximum Ratings ).
