ARM: MCB2140 Evaluation Board based on NXP LPC2148 MCU

Kit Overview

The Keil MCB2140MCB2140 Evaluation Board allows you to generate and test application programs for the NXP LPC2100 microcontroller family. With this hands-on process, you can determine the hardware and software requirements for current and future product development.

The MCB2140MCB2140 Evaluation Board ships with an LPC2148LPC2148 device that is a superset of several other device variants of the NXP LPC2100 microcontroller series. The MCB2140MCB2140 Board contains all hardware components required in a single-chip LPC2100 system.

The LPC2148LPC2148 microcontrollers are based on a 16-bit/32-bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, that combine the microcontroller with embedded high-speed flash memory ranging from 32 kB to 512 kB. A 128-bit wide memory interface and an unique accelerator architecture enable 32-bit code execution at the maximum clock rate. For critical code size applications, the alternative 16-bit Thumb mode reduces code by more than 30 % with minimal performance penalty.

Due to their tiny size and low power consumption, LPC2148LPC2148 is ideal for applications where miniaturization is a key requirement, such as access control and point-of-sale. Serial communications interfaces ranging from a USB 2.0 Full-speed device, multiple UARTs, SPI, SSP to I2C-bus and on-chip SRAM of 8 kB up to 40 kB, make these devices very well suited for communication gateways and protocol converters, soft modems, voice recognition and low end imaging, providing both large buffer size and high processing power. Various 32-bit timers, single or dual 10-bit ADC(s), 10-bit DAC, PWM channels and 45 fast GPIO lines with up to nine edge or level sensitive external interrupt pins make these microcontrollers suitable for industrial control and medical systems.

Key applications: access control, point-of-sale communication gateways and protocol converters, soft modems, voice recognition, low end imaging applications, etc
