1. 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 I
2
C-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.
2. Features and benefits

32-bit ARM Cortex-M3 microcontroller
Debug options:
Standard JTAG test interface for BSDL.
Serial Wire Debug.
Support for ETM ARM Cortex-M3 debug time stamping.
Digital peripherals:
Up to 51 General Purpose I/O (GPIO) pins with configurable pull-up/pull-down
resistors, repeater mode, input inverter, and pseudo open-drain mode. Eight pins
support programmable glitch filter.
Up to 8 GPIO pins can be selected as edge and level sensitive interrupt sources.
Two GPIO grouped interrupt modules enable an interrupt based on a
programmable pattern of input states of a group of GPIO pins.
High-current source output driver (20 mA) on one pin (P0_7).
High-current sink driver (20 mA) on true open-drain pins (P0_4 and P0_5).
Four general purpose counter/timers with a total of up to 8 capture inputs and 13
match outputs.
Programmable Windowed WatchDog Timer (WWDT) with a internal low-power
WatchDog Oscillator (WDO).
Repetitive Interrupt Timer (RI Timer).
Analog peripherals:
12-bit ADC with eight input channels and sampling rates of up to 500 kSamples/s.
Serial interfaces:
USB 2.0 full-speed device controller (LPC1345/46/47) with on-chip ROM-based
USB driver library.
USART with fractional baud rate generation, internal FIFO, a full modem control
handshake interface, and support for RS-485/9-bit mode and synchronous mode.
USART supports an asynchronous smart card interface (ISO 7816-3).
Two SSP controllers with FIFO and multi-protocol capabilities.
I
2
C-bus interface supporting the full I
2
C-bus specification and Fast-mode Plus with
a data rate of up to 1 Mbit/s with multiple address recognition and monitor mode.
Clock generation:
Crystal Oscillator with an operating range of 1 MHz to 25 MHz (system oscillator)
with failure detector.
12 MHz high-frequency Internal RC oscillator (IRC) trimmed to 1 % accuracy over
the entire voltage and temperature range. The IRC can optionally be used as a
system clock.
Internal low-power, low-frequency WatchDog Oscillator (WDO) with programmable
frequency output.
PLL allows CPU operation up to the maximum CPU rate with the system oscillator
or the IRC as clock sources.
A second, dedicated PLL is provided for USB (LPC1345/46/47).
Clock output function with divider that can reflect the crystal oscillator, the main
clock, the IRC, or the watchdog oscillator.
Power control:
Four reduced power modes: Sleep, Deep-sleep, Power-down, and Deep
power-down.
Power profiles residing in boot ROM allow optimized performance and minimized
power consumption for any given application through one simple function call.
