LPC2290中文资料飞利浦数据手册PDF规格书

General description

The 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.

特性 Features

Key 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.

■ 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.
