THNCFxxxxDG Series
TOSHIBA SMALL FORM FACTOR CARD
Lead-Free
DESCRIPTION
The THNCFxxxxDG series CompactFlash™ card is a flash technology based on ATA interface flash memory card. It is constructed with flash disk controller chip and NAND-type flash memory device. The CompactFlash™ card operates in both 5-Volt and 3.3-Volt power supplies. It comes in capacity of 128, 256, 512MB and 1GB unformatted for type-I card. Emulating IDE hard disk drives and being certified in accordance with the CompactFlash™ Certification Plan it is a perfect choice of solid-state mass-storage cards for battery backup handheld devices such as Digital Camera, Audio Player, PDA, or industrial application, or the applications that require high environment tolerance with high performance sustained write speed.

Electrical Interface

THNCFxxxxDG Series
• Physical Description:
The host is connected to the CompactFlash™ Storage Card using a standard 50-pin connector. The connector in the host consists of two rows of 25 male contacts each on 50 mil (1.27 mm) centers.
• Pin Assignments and Pin Type:
The signal/pin assignments are listed in the section “Pin Assignment and Pin Type”. Low active signals have a “ “ prefix. Pin types are Input, Output or Input/Output. Section “Electrical specification” and “DC characteristics” defines the all input and output type structures.
• Electrical Description:
The CompactFlash™ Storage Card functions in three basic modes: 1) PC Card ATA using I/O Mode, 2) PC Card ATA using Memory Mode and 3) True IDE Mode, which is compatible with most disk drives. CompactFlash™ Storage Cards are required to support all three modes. The CF Cards normally function in the first and second modes, however they can optionally function in True IDE mode. The configuration of the CompactFlash™ Card will be controlled using the standard PCMCIA configuration registers starting at address 200h in the Attribute Memory space of the storage card. Or for True IDE Mode, pin 9 being grounded. The configuration of the CF Card will be controlled using configuration registers. The configuration registers are starting at the address defined in the Configuration Tuple (CISTPL_CONFIG) in the Attribute Memory space of the CF Card. Signals, whose source is the host, is designated as inputs while signals that the CompactFlash™ Storage Card sources are outputs. The CompactFlash™ Storage Card logic levels conform to those specified in the PC Card Standard Release 8. Each signal has three possible operating modes:
1) PC Card Memory mode 2) PC Card I/O mode 3) True IDE mode True IDE mode is required for CompactFlash™ Storage cards. All outputs from the card are totem pole except the data bus signals that are bi-directional tri-state As a unique feature, the TOSHIBA CompactFlash™ Storage Card has automatic power down mode. When command process is completed, the card transits to this mode automatically. The card returns to active after receiving next command.
