The LPC2378 microcontrollers are based on a 16-bit/32-bit ARM7TDMI-S CPU with real-time emulation that combines the microcontroller with 512 kB of embedded high-speed flash memory. A 128-bit wide memory interface and a unique accelerator architecture enable 32-bit code execution at the maximum clock rate. For critical performance in interrupt service routines and DSP algorithms, this increases performance up to 30 % over Thumb mode. For critical code size applications, the alternative 16-bit Thumb mode reduces code by more than 30 % with minimal performance penalty.
- ARM7TDMI-S processor, running at up to 72 MHz.
- 32 kB of SRAM on the ARM local bus for high performance CPU access.
- 16 kB SRAM for Ethernet interface. Can also be used as general purpose SRAM.
- 8 kB SRAM for general purpose DMA use; also accessible by the USB.
- EMC provides support for static devices such as flash and SRAM as well as off-chip memory mapped peripherals.
- Advanced Vectored Interrupt Controller (VIC), supporting up to 32 vectored interrupts.
- Standard ARM test/debug interface for compatibility with existing tools.
- Emulation trace module supports real-time trace.
- Single 3.3 V power supply (3.0 V to 3.6 V).
- Four reduced power modes: idle, sleep, power-down, and deep power-down.
- Four external interrupt inputs configurable as edge/level sensitive
- Each peripheral has its own clock divider for further power saving.
- Brownout detect with separate thresholds for interrupt and forced reset.
- On-chip power-on reset.
