Overview

The Embest DevKit3250 Evaluation Board is designed around the Mini3250Mini3250 processor card using NXP’s LPC3250LPC3250 microprocessor which is built on a 90-nm, 266MHz ARM926EJ-S CPU core and a Vector Floating Point (VFP) coprocessor, designed for applications that require high performance, high integration, and low power consumption.

The CPU core board Mini3250Mini3250 (should be purchased separately) on Devkit3250, measuring only 75mm by 55mm, has an integrated LPC3250LPC3250 ARM926EJ core and provides Multiple Storage Media including 64MB SDRAM, 128MB bytes NAND FLASH, 4MB Nor Flash. It also supports SD card and USB mass storage devices and has one power indicating LED, one programmable LED and one 40 pin TFT-LCD connector on board. It connects to the Devkit3250 expansion board through two 2.0mm pitch 3-line 27-pin connectors. The expansion board has increased the core board’s I/Os capabilities. It brought out 8 UARTS, IrDA, Ethernet, Audio, ADC, RTC, Buzzer, Keys, EMC Bus and GPIOs.

The Mini3250Mini3250 processor card is based on NXP's 32-bit LPC3250LPC3250 ARM926EJ-S core microcontroller which is, amongst the LPC3000 series; the only ARM9 microcontroller that provides a vector floating-point co-processor. The LPC3000 series is able to run in ultra-low-power mode even down to 0.9V, as well as the lowest power consumption. The LPC3000 series owns abundant peripheral resource; one of the most distinguishing features is to provide 7 UART controllers, which is rare in ARM microprocessors. With such outstanding performance, the Mini3250 processor card is perfect to be employed in Industrial field, Medical Equipment, Intelligent Instrument, Consumer Electronics, and Communication Products.

Due to the same footprint of LPC3000 series, the Embest Mini3250Mini3250 processor card CPU is compatible with the LPC3220, LPC3230 and LPC3240. It enables users to choose the most appropriate product for their specifications. The Mini3250 core board can be mounted directly onto the expansion board of the Embest DevKit3250. The whole integrated design has exposed many of the LPC3250's features and allows a flexible way of updating Mini3250's capabilities.

The DevKit3250 board is preloaded with a ready-to-run Linux OS. Embest offers the Linux 2.6.27 BSP and all necessary documents and accessories with this Kit to effectively help with customer’s early development work. It can be also be integrated directly into customer’s next design.
