NXP | LPC1764FBD100,551

The LPC1769/68/67/66/65/64/63 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 LPC1768/67/66/65/64/63 operate at CPU frequencies of up to 100 MHz. The LPC1769 operates at CPU frequencies of up to 120 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 :

• ARM Cortex-M3 processor, running at frequencies of up to 100 MHz (LPC1768/67/66/65/64/63) or of up to 120 MHz (LPC1769). A Memory Protection Unit (MPU) supporting eight regions is included.
• ARM Cortex-M3 built-in Nested Vectored Interrupt Controller (NVIC).
• Up to 512 kB on-chip flash programming memory. Enhanced flash memory accelerator enables high-speed 120 MHz operation with zero wait states.
• In-System Programming (ISP) and In-Application Programming (IAP) via on-chip bootloader software.
• 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 100-pin LQFP package (14 mm × 14 mm × 1.4 mm).
• 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).
• Four external interrupt inputs 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.
• Clock output function that can reflect the main oscillator clock, IRC clock, RTC clock, CPU clock, and the USB clock.

Applications :

• eMetering
• Alarm systems
• Lighting
• White goods
• Industrial networking
• Motor control
