LPC2290 General Description

General descriptionThe LPC2290 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.FeaturesKey features■ 16/32-bit ARM7TDMI-S microcontroller in a LQFP144 package.■ 16 kB on-chip Static RAM.■ Serial boot-loader using UART0 provides in-system download and programming capabilities.■ 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.■ Two interconnected CAN interfaces with advanced acceptance filters. Additional serial interfaces include two UARTs (16C550), Fast I2C (400 kbits/s) and two SPIs™.■ Eight channel 10-bit A/D converter with conversion time as low as 2.44 µs.■ 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.■ Configurable external memory interface with up to four banks, each up to 16 Mb and 8/16/32 bit data width.■ Up to 76 general purpose I/O pins (5 V tolerant). Up to 9 edge/level sensitive external interrupt pins available.■ 60 MHz maximum CPU clock available from programmable on-chip Phase-Locked Loop.■ On-chip crystal oscillator with an operating range of 1 MHz to 30 MHz.■ Two low power modes, Idle and Power-down.■ Processor wake-up from Power-down mode via external interrupt.■ Individual enable/disable of peripheral functions for power optimization.■ Dual power supply: ◆ CPU operating voltage range of 1.65 V to 1.95 V (1.8 V ±0.15 V). ◆ I/O power supply range of 3.0 V to 3.6 V (3.3 V ±10%) with 5 V tolerant I/O pads.

Key Features

Enhancements introduced with LPC2290/01 device
CPU clock up to 72 MHz and 64 kB of on-chip static RAM.
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.
Dedicated result registers for ADC reduce interrupt overhead.
UART0/1 include fractional baud rate generator, auto-bauding capabilities and handshake flow-control fully implemented in hardware.
SSP serial controller supporting SPI, 4-wire SSI, and Microwire buses.
