6 / 52 page  2001-09-05 6/52 THNCFxxxMAA Series Preliminary version Electrical Interface Electrical Interface Electrical Interface Electrical Interface Physical Description Physical Description Physical Description 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 Pin Assignments and Pin Type Pin Assignments and Pin Type 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 Electrical Description Electrical Description 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 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 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. |
