Introduction

Key Features:

  • 32-Bit ARM7® Core Architecture
  • Full-Speed USB 2.0 Device
  • Very Fast On-Chip Flash Up to 512KB
  • Up to 40KB SRAM
  • 45 Fast I/O Pins with Up to 15MHz Switching
  • Vectored Interrupt Controller (VIC)
  • Very Small 10mm x 10mm LQFP Packaging
  • Ideal for Entertainment, Connectivity, and Display Applications
The LPC214x series is the only ARM7® microcontroller family with full USB 2.0 compliance and USB.org certification. The full-speed USB 2.0 device supports 32 end points with 2KB of endpoint RAM, 8KB of RAM usable by the USB DMA (LPC2146 and LPC2148 only), and all data transfer modes (Control, Interrupt, Bulk and Isochronous). These MCUs allow designers to add USB functionality to almost any end application — starting at only $3.60* for the LPC2141.
In addition to the USB 2.0 full-speed device, these low-power MCUs have from 32KB to 512KB of zero wait-state on-chip flash, 8KB to 40KB SRAM, 10-bit ADCs, 10-bit DAC, and a low-power Real Time Clock. These small 10mm x 10mm LQFP64 packaged controllers are loaded with serial communications interfaces including multiple UARTs, I2C, and SPI, as well as 45 fast general purpose I/O lines.
* MSRP US dollars based on 10Kpcs.
