LPC1549JBD64

The LPC15xx are ARM Cortex-M3 based microcontrollers for embedded applications

featuring a rich peripheral set with very low power consumption. 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.

LPC1549JBD64

The LPC15xx operate at CPU frequencies of up to 72 MHz. 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 LPC15xx includes up to 256 kB of flash memory, 32 kB of ROM, a 4 kB EEPROM,

and up to 36 kB of SRAM. The peripheral compliment includes 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-bit, 500 kSamples/s DAC, four voltage comparators with

internal voltage reference, and a temperature sensor. A DMA engine can service most

peripherals.
