ARM CPU Core Module based on LPC1857FET256 Supporting uC/OS-II
MINI1857 is an embedded core module built on LPC1857FET256 - a 32bit ARM Cortex-M3 microcontroller. By using it with an expansion board from Embest (EDM1070xx or EDM1043xx) or other dedicatedly designed boards built according to hardware interfaces of MINI1857, users can implement a quick function trimming so as to realize a shorter time to market.
The LPC1857 is an 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 LPC1857 MCU 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 LPC1857 MCU 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 (SCT) subsystem, two High-speed USB controllers, Ethernet, LCD, an external memory controller, and multiple digital and analog peripherals.
