What this MCU actually does
The NXP LPC1827JET100551 is a 32-bit ARM Cortex-M3 microcontroller running at 180 MHz. It carries 1 MB of Flash, 136 KB of SRAM, and 16 KB of EEPROM.
180 MHz — what it buys you on the bus
At 180 MHz, the Cortex-M3 core executes a single-cycle multiply or a hardware divide. The internal oscillator saves a crystal BOM line.
Connectivity and peripherals
The LPC1827JET100551 includes CANbus, USB (with OTG), I²C, SPI, UART/USART, and an external bus interface (EBI/EMI) for glueless connection to parallel SRAM or LCD controllers. Four 10-bit ADC channels and one 10-bit DAC cover basic analog front-end needs. Brown-out detect, POR, and a watchdog timer are built in — no external supervisor required for most designs.
Lifecycle and sourcing
This part is listed as Active in production. It is available through independent distribution; we source and quote it to order against an RFQ, with current pricing and availability confirmed at quote time. No last-time-buy or obsolescence notice is in effect.
