产品概述
NXP LPC2220FBD144 微控制器， 32位， ARM7TDMI， 75 MHz， 64 KB， 144 引脚， LQFP
The LPC2220FBD144 is a flashless 16-/32-bit Microcontroller based on 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. The device incorporates 16kB on-chip SRAM， 8-channel 10-bit A/D converter， three 32-bit timers， PWM channels， up to nine external interrupt pins and_76 general-purpose I/O pins.
.Serial bootloader using UART0 provides in-system download and_programming capabilities.EmbeddedICE-RT and_Embedded Trace interfaces offer real-time debugging.Two 32-bit timers， PWM unit， real-time clock and_watchdog.Multiple serial interfaces including two UARTs (16C550)， fast I2C-bus (400 Kbit/s) and_two SPIs.Vectored interrupt controller with configurable priorities and_vector addresses.Configurable external memory interface w/up to 4 banks， each up to 16MB and_8/16/32-bit data width.Up to 76 general purpose pins (5V tolerant) capable.Up to nine edge/level sensitive external interrupt pins available.75MHz Maximum CPU clock available from programmable on-chip PLL.On-chip crystal oscillator with an operating range of 1MHz to 25MHz.Power saving modes include Idle and_power-down.Processor wake-up from power-down mode via external interrupt.Individual enable/disable of peripheral functions for power optimization
