LPC1549JBD48QL Microcontroller Description

The LPC1549JBD48QL are ARM Cortex-M3-based embedded microcontrollers with a rich peripheral set and very low power consumption. The ARM Cortex-M3 is a next-generation core that provides system improvements such as increased debug tools and a greater level of support block integration.

The LPC1549JBD48QL can run at CPU speeds of up to 72 MHz. The ARM Cortex-M3 CPU has a three-stage pipeline and a Harvard architecture, with separate local instruction and data buses and a third bus for peripherals. An inbuilt prefetch unit that supports speculative branching is also included in the ARM Cortex-M3 CPU.

The LPC1549JBD48QL has up to 256 kB flash memory, 32 kB ROM, a 4 kB EEPROM, and up to 36 kB SRAM. One full-speed USB 2.0 device, two SPI interfaces, three USARTs, one Fast-mode Plus I2C-bus interface, one C CAN module, PWM/timer subsystem with four configurable, multi-purpose State Configurable Timers (SCTimer/PWM) with input pre-processing unit, a Real-time clock module with independent power supply and a dedicated oscillator, two 12-channel/12-bit, 2 Msamples/s ADCs, one 12- Most peripherals can be serviced by a DMA engine.
