ARM7 LPC2148 Microcontroller Socket

Introduction

ARM7 LPC2148 Microcontroller Socket is used with LPC2148 Pro Development Board. It is a standalone board for LPC2148 microcontroller. It has 12MHz crystal for system clock and 32KHz crystal for RTC. It has power on reset circuit with MCP130T brownout monitoring chip and power decoupling capacitors. This board can be used for LPC2148 based generic development.

Specifications

• Microcontroller: LPC2148 with 512K on chip memory
• Crystal for LPC2148: 12Mhz
