180 MHz Cortex-M3 with 1 MB Flash — what this MCU delivers
The NXP LPC1857JBD208E is a 32-bit ARM Cortex-M3 microcontroller running at 180 MHz, with 1 MB of on-chip Flash and 136 KB of SRAM. It sits in the LPC18xx series, targeting applications that need a balance of processing throughput, memory, and peripheral integration — think industrial gateways, motor drives, and communication concentrators. The 180 MHz core gives you headroom for real-time control loops and protocol stacks without pushing the part to its limit.
Rated for -40 to 105 °C ambient, the LPC1857JBD208E operates from 2.2 V to 3.6 V supply. The internal oscillator is included.
