1. General description
The LPC2290 microcontroller is based on a 16/32-bit ARM7TDMI-S CPU with real-time
emulation and embedded trace support. For critical code size applications, the alternative
16-bit Thumb mode reduces code by more than 30 % with minimal performance penalty.
With its 144-pin package, low power consumption, various 32-bit timers, 8-channel 10-bit
ADC, two advanced CAN channels, PWM channels and up to nine external interrupt pins
this microcontroller is particularly suitable for automotive and industrial control
applications as well as medical systems and fault-tolerant maintenance buses. The
LPC2290 provides up to 76 GPIOs depending on bus configuration. 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.
Remark: Throughout the data sheet, the term ‘LPC2290’ will apply to devices with and
without the /01 suffix. New devices will use the /01 suffix to differentiate from the original
devices only when necessary.
2. Features
2.1 Enhancements introduced with LPC2290/01 device
n CPU clock up to 72 MHz and 64 kB of on-chip static RAM.
n Fast GPIO ports enable port pin toggling up to 3.5 times faster than the original
LPC2290. A port pin can be read at any time regardless of its function.
n Dedicated result registers for ADC reduce interrupt overhead.
n UART0/1 include fractional baud rate generator, auto-bauding capabilities and
handshake flow-control fully implemented in hardware.
n SSP serial controller supporting SPI, 4-wire SSI, and Microwire buses.
2.2 Key features common for LPC2290 and LPC2290/01
n 16/32-bit ARM7TDMI-S microcontroller in a LQFP144 package.
n 16/64 kB on-chip static RAM.
n Serial bootloader using UART0 provides in-system download and programming
capabilities.
n 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.
n Two interconnected CAN interfaces with advanced acceptance filters. Additional serial
interfaces include two UARTs (16C550), Fast I
2
C-bus (400 kbit/s) and two SPIs.
