LPC2194

Features:

· 16/32-bit ARM7TDMI-S microcontroller in a tiny LQFP64 package.
· 16 kB on-chip Static RAM and 256 kB on-chip Flash Program Memory. 128-bit wide interface/accelerator enables high speed 60 MHz operation.
· In-System Programming (ISP) and In-Application Programming (IAP) via on-chip boot-loader software. Flash programming takes 1 ms per 512 byte line. Single sector or full chip erase takes 400 ms.
· EmbeddedICE-RT and Embedded Trace interfaces offer real-time debugging with on-chip RealMonitor software as well as high speed real-time tracing of instruction execution.
· Four interconnected CAN interfaces with advanced acceptance filters. Additional serial interfaces are two UARTs (16C550), Fast I²C (400 kbits/s) and two SPIs™.
· Two 32-bit timers (with 4 capture and 4 compare channels), PWM unit (6 outputs), Real Time Clock and Watchdog.
· Vectored Interrupt Controller with configurable priorities and vector addresses.
· Up to forty-six 5 V tolerant general purpose I/O pins. Up to 9 edge or level sensitive external interrupt pins  vailable.

Description

·The LPC2194 is based on a 16/32 bit ARM7TDMI-S™ CPU with real-time emulation and embedded trace support, together with 256 kilobytes (kB) of embedded high speed flash memory. A 128-bit wide memory interface and a unique accelerator architecture enable 32-bit code execution at maximum clock rate. For critical code size applications, the alternative 16-bit Thumb Mode reduces code by more than 30% with minimal performance penalty.

·With its compact 64 pin package, low power consumption, various 32-bit timers, 4-channel 10-bit ADC, 4 advanced CAN channels, PWM channels and 46 GPIO lines with up to 9 external interrupt pins this microcontroller is particularly suitable for automotive applications such as a CAN gateway that connects several CAN busses or a CAN bridge between sub networks at different speeds. Sensors with CAN interface or debugging via CAN are additional application that need more than 2 CAN interfaces. It is also an adequate solution for industrial control, medical systems and fault-tolerant maintenance buses. With a wide range of additional serial communications interfaces, it is also suited for communication gateways and protocol converters as well as many other general-purpose applications.
