描述 Description

The LPC18S37JBD144 is a Arm Cortex-M3 based microcontroller for embeddedapplications. The Arm Cortex-M3 is a next generation core that offers systemenhancements such as low power consumption, enhanced debug features, and a highlevel of support block integration.
The LPC18S37JBD144 operates at CPU frequencies of up to 180 MHz. The Arm Cortex-M3CPU incorporates a 3-stage pipeline and uses a Harvard architecture with separate localinstruction and data buses as well as a third bus for peripherals. The Arm Cortex-M3CPU also includes an internal prefetch unit that supports speculative branching.
The LPC18S37JBD144 includes 1 MB of flash and 136 kB of on-chip SRAM, 16 kB ofEEPROM memory, a quad SPI Flash Interface (SPIFI), a State-configurable Timer/PWM(SCTimer/PWM) subsystem, two High-speed USB controllers, Ethernet, an externalmemory controller, and multiple digital and analog peripherals.
