5. Functional Blocks

5.1 PCMCIA

5.1.1 Block Description
Figure 5.1 shows the PCMCIA control block. As shown in Figure 5.1, the PCMCIA control block contains a
controller (MR-SHPC-01 V2 from Marubun), a 68-pin PC card interface connector (CN3) and a power supply
controller IC (TPS2211DB from TI). This controller interfaces with the card(s) conforming to the PC Card
Standard 97 and has the following features:
• Internal memory windows (2 windows) and I/O window (one window)
•Card access timing adjustment function
• One-step read/write buffer
• Endian internal control circuit
• Support for 5.0V/3.3V cards
• External buffer not required
• Internal interrupt steering function
• Power-down function
• Internal suspend function
There are four kinds of controller interrupts (SIRQ3 to SIRQ0). Inputs to the H7760 are made by the IRL
codes. For details, refer to Marubun's MR-SHPC-01 V2 Manual.
