LPC1788FBD144,551                Description

The LPC178x/7x is an ARM Cortex-M3 based microcontroller for embedded applications requiring a high level of integration and low power dissipation. The ARM Cortex-M3 is a next generation core that offers better performance than the ARM7 at the same clock rate and other system enhancements such as modernized debug features and a higher level of support block integration. The ARM Cortex-M3 CPU incorporates a 3-stage pipeline and has a Harvard architecture with separate local instruction and data buses, as well as a third bus with slightly lower performance for peripherals. The ARM Cortex-M3 CPU also includes an internal prefetch unit that supports speculative branches.

LPC1788FBD144,551                Features

n Functional replacement for the LPC23xx and LPC24xx family devices.

n System:

u ARM Cortex-M3 processor, running at frequencies of up to 120 MHz. A Memory

Protection Unit (MPU) supporting eight regions is included.

u ARM Cortex-M3 built-in Nested Vectored Interrupt Controller (NVIC)

 Multilayer AHB matrix interconnect provides a separate bus for each AHB master.

AHB masters include the CPU, USB, Ethernet, and the General Purpose DMA

controller. This interconnect provides communication with no arbitration delays

unless two masters attempt to access the same slave at the same time.

u Split APB bus allows for higher throughput with fewer stalls between the CPU and

DMA. A single level of write buffering allows the CPU to continue without waiting for

completion of APB writes if the APB was not already busy.

u Cortex-M3 system tick timer, including an external clock input option.

u Standard JTAG test/debug interface as well as Serial Wire Debug and Serial

WireTrace Port options.

u Embedded Trace Macrocell (ETM) module supports real-time trace.

u Boundary scan for simplified board testing.

u Non-maskable Interrupt (NMI) input.

LPC1788FBD144,551                Applications

n Communications:

u Point-of-sale terminals, web servers, multi-protocol bridges

n Industrial/Medical:

u Automation controllers, application control, robotics control, HVAC, PLC, inverters,

circuit breakers, medical scanning, security monitoring, motor drive, video intercom

n Consumer/Appliance:
