LPC2880; LPC2888

16/32-bit ARM microcontrollers with external memory interface

Endpoints with small packet sizes can be handled by software via registers in the USB

controller. In particular, Control Endpoint 0 is always handled in this way.

6.17.1 Features

• Fully compliant with USB 2.0 speciﬁcation (HS and FS).

• 16 physical endpoints.

• Supports Control, Bulk, Interrupt and Isochronous endpoints.

• Endpoint type selection by software

• Endpoint maximum packet size setting by software

• Supports Soft Connect feature (requires an external 1.5 k

Ω resistor connected to the

USB_RPU pad).

• Supports bus-powered capability with low suspend current.

• Four Read/Write DMA channels.

• Supports Burst data transfers on the AHB.

• Supports Retry and Split transactions on the AHB.

6.18 SD/MMC card interface

The Secure Digital and Multimedia Card Interface (MCI) is an interface between the

Advanced Peripheral Bus (APB) system bus and multimedia and/or secure digital memory

cards.

The interface provides all functions speciﬁc to the Secure Digital/MultiMedia memory

card, such as the clock generation unit, power management control, command, data

transfer, interrupt generation, and DMA request generation.

6.18.1 Features

• Conformance to Multimedia Card Speciﬁcation v2.11.

• Conformance to Secure Digital Memory Card Physical Layer Speciﬁcation, v0.96.

• Use as a multimedia card bus or a secure digital memory card bus host. It can be

connected to several multimedia cards, or a single secure digital memory card.

• DMA transfers are supported through the Simple DMA facility.

6.19 LCD interface

The LCD interface contains logic to interface to a 6800 or 8080 bus compatible LCD

controller. The LCD interface is compatible with the 6800 bus standard and the 8080 bus

standard, with one address pin (RS) for selecting the data or instruction register.

The LCD interface makes use of a conﬁgurable clock (programmed in the CGU) to adjust

the speed of the 6800/8080 bus to the speed of the connected peripheral.

6.19.1 Features

• 8-bit or 4-bit parallel interface mode: 6800-series, 8080-series.

• Supports multiple frequencies for the bus, to support high and low speed LCD

controllers.
