NXP Cortex M3 Microprocessors
Information on NXP's LPC1300 and LPC1700 Family of ARM Cortex M3 Microprocessors
NXP's LPC1300 family of chips is based on the ARM Cortex M3 core and is capable of running at speeds up to 72MHz. Chips in this family have up to 32KB Flash and 8KB SRAM, and contain USB 2.0 (134x only), an 8-channel 10-bit ADC, UART, SPI, I²C, and an integrated clock generator. They are relatively low power devices at a very attractive price point, and are useful in cost-senstive applications. All chips in this family are available in space-saving QFN33 packaging, or in QFP48 packaging if you require a higher pin count.
The LPC1700 family of chips is also based on the ARM Cortex M3 core, and with a maximum speed of 100MHz, up to 512KB Flash and 64KB SRAM, and a very robust collection of on-chip peripherals (Ethernet, USB+Host, CAN, DAC, etc.), it's an excellent general-purpose chip to consider for moderately complex projects. We expect that in the future the LPC1700 family will begin to replace several members of the ARM7-based LPC2100 and LPC2300 family in popularity since the 1700's offer a newer design and added functionality at a lower price-point.
