Product data sheet
1. General description
The LPC2377/78 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 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.
The LPC2377/78 is ideal for multi-purpose serial communication applications. It
incorporates a 10/100 Ethernet Media Access Controller (MAC), USB full speed device
with 4 kB of endpoint RAM (LPC2378 only), four UARTs, two CAN channels (LPC2378
only), 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
32 kB, 16 kB SRAM for Ethernet, 8 kB SRAM for USB and general purpose use, together
with 2 kB battery powered SRAM make this device very well suited for communication
gateways and protocol converters. Various 32-bit timers, an improved 10-bit ADC, 10-bit
DAC, PWM unit, a CAN control unit, and up to 104 fast GPIO lines with up to 50 edge and
up to four level sensitive external interrupt pins make these microcontrollers particularly
suitable for industrial control and medical systems.
2. Features
I ARM7TDMI-S processor, running at up to 72 MHz.
I 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.
I 32 kB of SRAM on the ARM local bus for high performance CPU access.
I 16 kB SRAM for Ethernet interface. Can also be used as general purpose SRAM.
I 8 kB SRAM for general purpose DMA use also accessible by the USB.
I 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.
I EMC provides support for static devices such as flash and SRAM as well as off-chip
memory mapped peripherals.
I Advanced Vectored Interrupt Controller (VIC), supporting up to 32 vectored interrupts.
