LPC2194
Single-chip 16/32-bit microcontrollers; 256 kB ISP/IAP Flash
with 10-bit ADC and CAN
Rev. 01 — 06 February 2004
Preliminary data
1. General 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.
2. Features
2.1 Key features
s 16/32-bit ARM7TDMI-S microcontroller in a tiny LQFP64 package.
s 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.
s 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.
s 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.
s Four interconnected CAN interfaces with advanced acceptance filters. Additional
serial interfaces are two UARTs (16C550), Fast I²C (400 kbits/s) and two SPIs™.
s Four channel 10-bit A/D converter with conversion time as low as 2.44 µs.
s Two 32-bit timers (with 4 capture and 4 compare channels), PWM unit (6 outputs),
Real Time Clock and Watchdog.
s Vectored Interrupt Controller with configurable priorities and vector addresses.
s Up to forty-six 5 V tolerant general purpose I/O pins. Up to 9 edge or level
sensitive external interrupt pins available.
s Operating temperature range from −40 °C to +105 °C.
