Description

This is 16/32 Bit Microcontroller. LPC2142, 2148 Single-chip 16, 32-bit microcontrollers; 64, 512 kB flash with ISP, IAP, USB 2.0 full-speed device, 10-bit ADC and DAC Rev. 01 22 June 2005 Preliminary data sheet 1. General description The LPC2142, 2148 microcontrollers are based on a 32, 16-bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, that combines the microcontroller with 64 kB and 512 kB of embedded high-speed flash memory. A 128-bit wide memory interface and a 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, LPC2142, 2148 are ideal for applications where miniaturization is a key requirement, such as access control and point-of-sale. A blend of serial communications interfaces ranging from a USB 2.0 Full-speed device, multiple UARTs, SPI, SSP to I2C-bus and on-chip SR.
