LPC1759/58/56/54/52/51

32-bit ARM Cortex-M3 microcontroller

‹ Repetitive Interrupt Timer (RIT) provides programmable and repeating timed

interrupts.

‹ Each peripheral has its own clock divider for further power savings.

„ Standard JTAG test/debug interface for compatibility with existing tools. Serial Wire

Debug and Serial Wire Trace Port options.

„ Emulation trace module enables non-intrusive, high-speed real-time tracing of

instruction execution.

„ Integrated PMU (Power Management Unit) automatically adjusts internal regulators to

minimize power consumption during Sleep, Deep sleep, Power-down, and Deep

power-down modes.

„ Four reduced power modes: Sleep, Deep-sleep, Power-down, and Deep power-down.

„ Single 3.3 V power supply (2.4 V to 3.6 V).

„ One external interrupt input configurable as edge/level sensitive. All pins on Port 0 and

Port 2 can be used as edge sensitive interrupt sources.

„ Non-maskable Interrupt (NMI) input.

„ The Wakeup Interrupt Controller (WIC) allows the CPU to automatically wake up from

any priority interrupt that can occur while the clocks are stopped in Deep sleep,

Power-down, and Deep power-down modes.

„ Processor wake-up from Power-down mode via any interrupt able to operate during

Power-down mode (includes external interrupts, RTC interrupt, USB activity, Ethernet

wake-up interrupt (LPC1758 only), CAN bus activity, Port 0/2 pin interrupt, and NMI).

„ Brownout detect with separate threshold for interrupt and forced reset.

„ Power-On Reset (POR).

„ Crystal oscillator with an operating range of 1 MHz to 25 MHz.

„ 4 MHz internal RC oscillator trimmed to 1 % accuracy that can optionally be used as a

system clock.

„ PLL allows CPU operation up to the maximum CPU rate without the need for a

high-frequency crystal. May be run from the main oscillator, the internal RC oscillator,

or the RTC oscillator.

„ USB PLL for added flexibility.

„ Code Read Protection (CRP) with different security levels.

„ Unique device serial number for identification purposes.

„ Available as 80-pin LQFP package (12 mm × 12 mm × 1.4 mm).

„ eMetering

„ Lighting

„ Industrial networking

„ Alarm systems

„ White goods

„ Motor control
