4.0 APPENDIX
4.1 Differences between CF-ATA and PC Card-ATA/True IDE
This section details differences between CF-ATA vs. PC Card ATA and the differences between CF-ATA vs. True IDE.
4.1.1 Electrical Differences
4.1.1.1 TTL Compatibility
CF is not TTL compatible, it is a purely CMOS interface. Refer to section 2.3.2 of this specification.
4.1.1.2 Pull Up Resistor Input Leakage Current
The minimum pull up resistor input leakage current is 50K ohms rather than the 10K ohms stated in the PCMCIA
specification.
4.1.2 Functional Differences
4.1.2.1 Additional Set Features Codes in CF-ATA
The following Set Features codes are not PC Card ATA or True IDE, but provide additional functionality in CF-ATA.
69H, Accepted for backward compatibility
96H, Accepted for backward compatibility
97H, Accepted for backward compatibility
9AH, Set the host current source capability
4.1.2.2 Additional Commands in CF-ATA
The following commands are not standard PC Card ATA commands, but provide additional functionality in CF-ATA.
The command codes for the commands below are defined as vendor unique in PC Card ATA/True IDE.
C0H, Erase Sectors
87H, Translate Sector
F5H, Wear Level
The command codes for the commands below are defined as reserved in PC Card ATA/True IDE:
03H, Request Sense
38H, Write Without Erase
CDH, Write Multiple Without Erase
4.1.2.3 Idle Timer
The Idle timer uses an incremental value of 5 ms, rather than the 5 sec minimum increment value specified in PC
Card ATA/True IDE.
4.1.2.4 Recovery from Sleep Mode
For CF devices, recovery from sleep mode is accomplished by simply issuing another command to the device. A
hardware or software reset is not required.
