Industry’s lowest power Cortex-M3 based microcontrollers

NXP brings a new level of power performance to the ARM architecture with the LPC1300 series, the industry’s lowest-power Cortex-M3 MCUs. These new MCUs consume approximately 200 μA/MHz, bringing low-power benefits to a wide range of 16/32-bit applications.

Key features

• ARM Cortex-M3 processor
• 70-MHz operation
• Nested Vectored Interrupt Controller for fast deterministic interrupts
• Three reduced-power modes: Sleep, Deep-sleep, and Deep power-down
• Memories
• Up to 32 KB Flash memory
• Up to 8 KB SRAM
• Serial Peripherals
• USB 2.0 full-speed device controller with on-chip PHY
• UART with fractional baud rate generation, internal FIFO, and RS-485 support
• SSP/SPI controller with FIFO and multi-protocol capabilities
• I2C-bus interface supporting full I2C-bus specification and Fast mode plus with a data rate of 1 Mbit/s with multiple address recognition and monitor mode
• Analog Peripherals:
• 10-bit Analog-to-Digital Converter with eight channels and conversion rates up to 250K samples per second
• Other peripherals:
• Up to 42 General Purpose I/O (GPIO) pins with configurable pull-up/down resistors and a new, configurable open-drain operating mode
• Four general purpose counter/timers, with a total of four capture inputs and 13 match outputs
• Programmable Watchdog Timer (WDT) with lock-out feature
• System tick timer
• Each peripheral has its own clock divider for power savings

Applications

• Battery-powered systems
• e-Metering
• Consumer peripherals
• Remote sensors
• 16/32-bit applications

Built around a Cortex-M3 Rev2 processor core, the LPC1300 is equipped with up to 32 KB of Flash and up to 8 KB of SRAM, uses a single 3.3-V power supply (for operation between 2.0 V and 3.6 V), and is available in LQFP48 and HVQFN 33 packages.

The LPC1300 series is pin-to-pin compatible with the LPC1100 series, NXP’s new family of Cortex-M0 MCUs, so it gives designers a straightforward migration path to the even lowerpower features of the Cortex-M0 architecture.

Also, in keeping with NXP’s existing line of more than 50 USBequipped ARM MCUs, the LPC134x offers support for USB full-speed operation. HID and mass storage USB driver software is included in a dedicated on-chip ROM, maximizing the amount of Flash memory available for user code.

Additional features

• Serial Wire Debug and Serial Wire Trace Port
• High-current output driver (20 mA) on one pin
• High-current sink drivers (20 mA) on two pins
• Integrated PMU (Power Management Unit) to minimize power consumption during Sleep, Deep-sleep, and Deep powerdown modes
• Single 3.3 V power supply (2.0 V to 3.6 V)
• 15 GPIO pins can be used as edge and level sensitive interrupt sources
• Clock generation unit with divider that can reflect the main oscillator clock, IRC clock, CPU clock, and Watchdog clock.
• Processor wake-up from Deep-sleep mode via interrupts from various peripherals
• Brownout detect with four separate thresholds for interrupt and forced reset
• Power-On Reset (POR)
• Crystal oscillator with an operating range of 1 MHz to 25 MHz
• 12 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 Watchdog oscillator.
• Available as 48-pin LQFP package and 33-pin HVQFN package
