LPC2378FBD144

Product Summary

The LPC2378FBD144 is a Single-chip 16-bit/32-bit microcontroller. The LPC2378FBD144 microcontroller is 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 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.

Parametrics

LPC2378FBD144 absolute maximum ratings: (1)supply voltage (1.8 V) : 1.65 to 1.95 V; (2)supply voltage (3.3 V) : 3.0 to 3.6 V; (3)DC-to-DC converter supply voltage : 3.0 to 3.6 V; (4)analog 3.3 V pad supply voltage : -0.5 to +4.6 V; (5)input voltage on pin VBAT : -0.5 to +4.6 V; (6)input voltage on pin VREF : -0.5 to +4.6 V; (7)analog input voltage : -0.5 to +5.1 V.

Features

LPC2378FBD144 features: (1)ARM7TDMI-S processor, running at up to 72 MHz; (2)Up to 512 kB 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)32 kB of SRAM on the ARM local bus for high performance CPU access; (4)16 kB SRAM for Ethernet interface. Can also be used as general purpose SRAM; (5)8 kB 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)General Purpose AHB DMA controller (GPDMA) that can be used with the SSP serial interfaces, the I2S port, and the Secure Digital/MultiMediaCard (SD/MMC) card port, as well as for memory-to-memory transfers.
