1.General descriptionThe LPC185x/3x/2x/1x are ARM Cortex-M3 based microcontrollers 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 LPC185x/3x/2x/1x operate at CPU frequencies of up to 180 MHz. The ARMCortex-M3 CPU incorporates a 3-stage pipeline and uses a Harvard architecture withseparate local instruction and data buses as well as a third bus for peripherals. The ARMCortex-M3 CPU also includes an internal prefetch unit that supports speculativebranching.The LPC185x/3x/2x/1x include up to 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, LCD, an externalmemory controller, and multiple digital and analog peripherals.For additional documentation related to the LPC18xx parts, see Section 17 “References”.2.Features and benefits Processor core ARM Cortex-M3 processor (version r2p1), running at CPU frequencies of up to180 MHz. ARM Cortex-M3 built-in Memory Protection Unit (MPU) supporting eight regions. ARM Cortex-M3 built-in Nested Vectored Interrupt Controller (NVIC). Non-maskable Interrupt (NMI) input. JTAG and Serial Wire Debug, serial trace, eight breakpoints, and four watch points. Enhanced Trace Module (ETM) and Enhanced Trace Buffer (ETB) support. System tick timer. On-chip memory Up to 1 MB on-chip dual bank flash memory with flash accelerator. 16 kB on-chip EEPROM data memory. 136 kB SRAM for code and data use. Multiple SRAM blocks with separate bus access. 64 kB ROM containing boot code and on-chip software drivers. 64 bit 256 bit of One-Time Programmable (OTP) memory for general-purposeuse. Clock generation unitLPC185x/3x/2x/1x32-bit ARM Cortex-M3 MCU; up to 1 MB flash and 136 kBSRAM; Ethernet, two High-speed USB, LCD, EMCRev. 5.2 — 8 March 2016Product data sheet
