LPC2292/LPC2294
16/32-bit ARM microcontrollers; 256 kB ISP/IAP Flash with
CAN, 10-bit ADC and external memory interface
Rev. 01 鈥?05 February 2004
Preliminary data
1. General description
The LPC2292/LPC2294 are based on a 16/32 bit ARM7TDMI-S鈩?CPU with real-time
emulation and embedded trace support, together with 256 kilobytes (kB) of embedded
high speed 鏗俛sh 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 their 144 pin package, low power consumption, various 32-bit timers, 8-channel
10-bit ADC, 2/4 (LP2292/LPC2294) advanced CAN channels, PWM channels and up
to 9 external interrupt pins these microcontrollers are particularly suitable for
automotive and industrial control applications as well as medical systems and
fault-tolerant maintenance buses. Number of available GPIOs ranges from 76 (with
external memory) through 112 (single-chip). With a wide range of additional serial
communications interfaces, they are 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 LQFP144 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
the on-chip RealMonitor software as well as high speed real-time tracing of
instruction execution.
s
Two/four (LPC2292/2294) interconnected CAN interfaces with advanced
acceptance 鏗乴ters. Additional serial interfaces include two UARTs (16C550), Fast
I
2
C (400 kbits/s) and two SPIs鈩?
s
Eight channel 10-bit A/D converter with conversion time as low as 2.44
碌s.
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 con鏗乬urable priorities and vector addresses.
s
Con鏗乬urable external memory interface with up to four banks, each up to 16 Mb
and 8/16/32 bit data width.
s
Up to 112 general purpose I/O pins (5 V tolerant). Up to 9 edge/level sensitive
external interrupt pins available.
