General description
The LPC1315/16/17/45/46/47 are ARM Cortex-M3 based microcontrollers for embedded
applications featuring a high level of integration and 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.
The LPC1315/16/17/45/46/47 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.
Equipped with a highly flexible and configurable Full-Speed USB 2.0 device controller
available on the LPC1345/46/47, this series brings unparalleled design flexibility and
seamless integration to today’s demanding connectivity solutions.
The peripheral complement of the LPC1315/16/17/45/46/47 includes up to 64 kB of flash
memory, 8 kB or 10 kB of SRAM data memory, one Fast-mode Plus I2C-bus interface, one
RS-485/EIA-485 USART with support for synchronous mode and smart card interface,
two SSP interfaces, four general purpose counter/timers, an 8-channel, 12-bit ADC, and
up to 51 general purpose I/O pins.
