LPC3152/3154
6.9 Memory Card Interface (MCI)
The MCI controller interface can be used to access memory cards according to the
Secure Digital (SD) and Multi-Media Card (MMC) standards. The host controller can be
used to interface to small form factor expansion cards compliant to the SDIO card
standard as well. Finally, the MCI supports CE-ATA 1.1 compliant hard disk drives.
This module has the following features:
• One 8-bit wide interface.
• Supports high-speed SD, versions 1.01, 1.10 and 2.0.
• Supports SDIO version 1.10.
• Supports MMCplus, MMCmobile, and MMCmicro cards based on MMC 4.1.
• Supports SDHC memory cards.
• CRC generation and checking.
• Supports 1/4-bit SD cards.
• Card detection and write protection.
• FIFO buffers of 16 bytes deep.
• Host pull-up control.
• SDIO suspend and resume.
• 1-byte to 65 535-byte blocks.
• Suspend and resume operations.
• SDIO Read-wait.
• Maximum clock speed of 52 MHz (MMC 4.1).
• Supports CE-ATA 1.1.
• Supports 1-bit, 4-bit, and 8-bit MMC cards and CE-ATA devices.
6.10 Universal Serial Bus 2.0 High Speed On-The-Go (OTG)
The USB OTG module allows the LPC3152/3154 to connect directly to a USB host such
as a PC (in device mode) or to a USB device in host mode. In addition, the LPC3152/3154
has a special, built-in mode in which it enumerates as a Device Firmware Upgrade (DFU)
class, which allows for a (factory) download of the device firmware through USB.
This module has the following features:
• Complies with Universal Serial Bus specification 2.0.
• Complies with USB On-The-Go supplement.
• Complies with Enhanced Host Controller Interface Specification.
• Supports auto USB 2.0 mode discovery.
• Supports all high-speed USB-compliant peripherals.
• Supports all full-speed USB-compliant peripherals.
• Supports software Host Negotiation Protocol (HNP) and Session Request Protocol
(SRP) for OTG peripherals.
• Contains UTMI+ compliant transceiver (PHY).
• Supports Interrupts.
