LPC313x ARM926EJ-S Processor


NXP Semiconductors and Digi-Key introduce LPC313x ARM926EJ-S Processor with High Speed USB 2.0 OTG

NXP Semiconductor's LPC313x ARM926EJ-S Processor

NXP Semiconductor's LPC313x family combines a 180MHz ARM926EJ CPU core, high-speed USB 2.0 On-The-Go (OTG), up to 192kB SRAM, NAND flash controller, flexible external bus interface, 4-channel 10-bit A/D converter, and a myriad of serial and parallel interfaces. To optimize system power consumption, the LPC313x has multiple power domains and a very flexible Clock Generation Unit (CGU) that provides dynamic clock gating and scaling.

The USB interface contains a UTMI+ compliant transceiver (PHY), dedicated PLL, and a dedicated DMA engine. This provides high speed transfer rates up to 480Mbps and supports device, host and OTG operations.

Overview

The LPC313x allows booting from NAND flash, SPI flash, SD/MMC cards, UART, or USB. The integrated NAND flash controller provides an 8-bit Error Correction Code (ECC) and supports up to four NAND flash devices that can be any combination of SLC type NAND flash and MLC type NAND flash up to a capacity of 16GB. An 8/16-bit Multi-Port Memory Controller (MPMC) provides access to 64MB of SDRAM and 256kB of SRAM and/or memory mapped peripherals. The Memory Card Interface (MCI) provides access to memory cards compliant with MMC 4.1, SD 2.0 (including high capacity) and SDIO 1.1 standards as well as CE ATA 1.1 compatible storage devices. Serial interfaces include a full-duplex master/slave SPI/SSI with DMA support, two fast master/slave I²C bus (400kbps) interfaces with slave, single and multi-master support, two I²S, PCM and a fast UART with DMA support, IrDA and hardware-flow control.

The LPC313x has a 4-channel 10bit 400kHz A/D converter, four 32-bit timers, a PWM channel that supports pulse width and pulse density modulation, a Watchdog timer, and a flexible and versatile interrupt controller. For those applications that require visual interaction, the LPC313x integrates a 4/8/16-bit 6800/8080 compatible LCD interface.

A four-layer, 32-bit, 90MHz AHB matrix provides a separate bus for each of the four AHB masters (DMA, D-cache, I-cache, USB controller). This eliminates arbitration delays, except when two masters attempt to access the same slave at the same time.
