General description
The LPC1311/13/42/43 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 LPC1311/13/42/43 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 peripheral complement of the LPC1311/13/42/43 includes up to 32 kB of flash
memory, up to 8 kB of data memory, USB Device (LPC1342/43 only), one Fast-mode Plus
I2C-bus interface, one UART, four general purpose timers, and up to 42 general purpose
I/O pins.
Remark: The LPC1311/13/42/43 series consists of the LPC1300 series (parts
LPC1311/13/42/43) and the LPC1300L series (parts LPC1311/01 and LPC1313/01). The
LPC1300L series features the following enhancements over the LPC1300 series:
Power profiles with lower power consumption in Active and Sleep modes.
Four levels for BOD forced reset.
Second SSP controller (LPC1313FBD48/01 only).
Windowed Watchdog Timer (WWDT).
Internal pull-up resistors pull up pins to full VDD level.
Programmable pseudo open-drain mode for GPIO pins.
