NXP | LPC1311FHN33,551

LPC1311FHN33,551 is a 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.

Features:

• 32 kB (LPC1343/13)/16 kB (LPC1342)/8 kB (LPC1311) on-chip flash programming memory
• 8 kB (LPC1343/13)/4 kB (LPC1342/11) SRAM
• In-System Programming (ISP) and In-Application Programming (IAP) via on-chip bootloader software
• Selectable boot-up: UART or USB (USB on LPC134x only)
• USB 2.0 full-speed device controller with on-chip PHY for device (LPC1342/43 only)
• UART with fractional baud rate generation, modem, internal FIFO, and RS-485/EIA-485 support
• Single power supply (2.0 V to 3.6 V)
• Three reduced power modes: Sleep, Deep-sleep, and Deep power-down.

Applications:

• eMetering
• Lighting
• Alarm systems
• White goods
