HANBit CFC-xxxSx Series
5 / 5 HANBit Electronics Co., Ltd.
Electrical Interface
Physical Description
The host is connected to the CompactFlash Storage Card or CF+ 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 Table 4. Low active signals have a “-” prefix. Pin types are
Input, Output or Input/Output. Section 4.3 defines the DC characteristics for 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
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 starting at the address
defined in the configuration Tuple (CISTPL_CONFIG) in the Attribute Memory space of the CF
Card.
Signal description describes the I/O signals. Signals whose source is the host are 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 PCMCIA Release 2.1 specification.
Each signal has three possible operating modes:
1) PC Card Memory mode
2) PC Card I/O mode
3) True IDE
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.
