The LPC18S37/LPC18S57 are ARM Cortex-M3 based microcontrollers for embedded applications. The ARM Cortex-M3 is a next generation core that offers system enhancements such as low power consumption, enhanced debug features, and a high level of support block integration. The LPC18S37/LPC18S57 operate at CPU frequencies of up to 180 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. The LPC18S5x/S3x include up to 1 MB of flash and 136 kB of on-chip SRAM, 16 kB of EEPROM memory, a quad SPI Flash Interface (SPIFI), a State-configurable Timer/PWM two High-speed USB controllers, Ethernet, LCD, an external memory controller, and multiple digital and analog peripherals.
Available in LBGA256 packages.
