LPC2142 Datasheet | Philips Semiconductors

description The LPC2142/2148 microcontrollers are based on a 32/16-bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, that bines the microcontroller with 64 k B and 512 k B 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 munications interfaces ranging from a USB 2.0 Full-speed device, multiple UARTs, SPI, SSP to I2C-bus and on-chip SRAM of 16 k B/40 k B, make these devices very well suited for munication gateways and protocol converters, soft modems, voice recognition and low end imaging, providing both large buffer size and high...
