LPC1548JBD64QL

The LPC1548JBD64QL is a 32-bit Microcontroller based on ARM Cortex-M3 core with RISC architecture operates at a maximum frequency of 72MHz. The ARM Cortex-M3 is a next generation core that offers system enhancements such as enhanced debug features and a higher level of support block integration. The ARM Cortex-M3 CPU incorporates a 3-stage pipeline and uses a Harvard architecture with separate local instruction and data buses as well as a third bus for peripherals. The ARM Cortex-M3 CPU also includes an internal prefetch unit that supports speculative branching. The device incorporates 128kB internal flash, 20kB internal RAM, 4kB EEPROM, two 12-channel 12-bit A/D converter with sample rates of up to 2Msps and 44 general-purpose I/O pins. This device also features peripherals like one full-speed USB 2.0 device, two SPI interfaces, three USARTs, a fast-mode plus I2C-bus interface and a CAN module.
