LPC2378FBD144

Product Summary

The LPC2378FBD144 is a Single-chip 32-bit microcontroller. It is based on a 32-bit ARM7TDMI-S CPU with real-time emulation that combines the microcontroller with 512 kB of embedded high-speed flash memory. The LPC2378FBD144 is ideal for multi-purpose serial communication applications. It incorporates a 10/100 Ethernet Media Access Controller (MAC), USB full speed device with 4kB of endpoint RAM, four UARTs, two CAN channels, an SPI interface, two Synchronous Serial Ports (SSP), three I2C-bus interfaces, an I2S-bus interface, and an External Memory Controller (EMC). This blend of serial communications interfaces combined with an on-chip 4 MHz internal oscillator, SRAM of 32kB, 16kB SRAM for Ethernet, 8kB SRAM for USB and general purpose use, together with 2kB battery powered SRAM make the LPC2378FBD144 very well suited for communication gateways and protocol converters.

Features

LPC2378FBD144 features: (1) ARM7TDMI-S processor, running at up to 72 MHz; (2) Up to 512kB on-chip flash program memory with In-System Programming (ISP) and In-Application Programming (IAP) capabilities. Flash program memory is on the ARM local bus for high performance CPU access; (3)32kB of SRAM on the ARM local bus for high performance CPU access; (4)16kB SRAM for Ethernet interface. Can also be used as general purpose SRAM; (5)8kB SRAM for general purpose DMA use also accessible by the USB; (6)Dual Advanced High-performance Bus (AHB) system that provides for simultaneous Ethernet DMA, USB DMA, and program execution from on-chip flash with no contention between those functions. A bus bridge allows the Ethernet DMA to access the other AHB subsystem; (7)EMC provides support for static devices such as flash and SRAM as well as off-chip memory mapped peripherals; (8)Advanced Vectored Interrupt Controller (VIC), supporting up to 32 vectored interrupts; (9)Standard ARM test/debug interface for compatibility with existing tools; (10)Emulation trace module supports real-time trace; (11)Single 3.3 V power supply (3.0 V to 3.6 V); (12)Three reduced power modes: idle, sleep, and power-down; (13)Four external interrupt inputs configurable as edge/level sensitive. All pins on PORT0 and PORT2 can be used as edge sensitive interrupt sources.
