LPC4370

32-bit ARM Cortex-M4/M0 microcontroller

– Extended wait

• Four chip selects for synchronous memory and four chip selects for static memory

devices.

• Power-saving modes dynamically control EMC_CKEOUT and EMC_CLK signals to

SDRAMs.

• Dynamic memory self-refresh mode controlled by software.

• Controller supports 2048 (A0 to A10), 4096 (A0 to A11), and 8192 (A0 to A12) row

address synchronous memory parts. That is typical 512 MB, 256 MB, and 128 MB

parts, with 4, 8, 16, or 32 data bits per device.

• Separate reset domains allow the for auto-refresh through a chip reset if desired.

• SDRAM clock can run at full or half the Cortex-M4 core frequency.

Note: Synchronous static memory devices (synchronous burst mode) are not supported.

7.18.5 High-speed USB Host/Device/OTG interface (USB0)

The USB OTG module allows the LPC4370 to connect directly to a USB Host such as a

PC (in device mode) or to a USB Device in host mode.

7.18.5.1

Features

• Contains UTMI+ compliant transceiver (PHY).

• 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.

• Supports interrupts.

• This module has its own, integrated DMA engine.

• USB interface electrical test software included in ROM USB stack.

7.18.6 High-speed USB Host/Device interface with ULPI (USB1)

The USB1 interface can operate as a full-speed USB Host/Device interface or can

connect to an external ULPI PHY for High-speed operation.

7.18.6.1

Features

• Complies with Universal Serial Bus specification 2.0.

• Complies with Enhanced Host Controller Interface Specification.

• Supports auto USB 2.0 mode discovery.

• Supports all high-speed USB-compliant peripherals if connected to external ULPI

PHY.

• Supports all full-speed USB-compliant peripherals.

• Supports interrupts.
