LPC2144FBD64 Datasheet PDF - NXP

●The LPC2144FBD64 is a 16-/32-bit Microcontroller based on ARM7TDMI-S CPU with real-time emulation and embedded trace support. A 128-bit wide memory interface and an 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. The device incorporates 128kB embedded high speed flash, 16kB on-chip SRAM, 16-channel 10-bit A/D converter, 10-bit D/A converter, three 32-bit timers, PWM channels and 45 general-purpose I/O pins.

● In-system programming/In-application programming (ISP/IAP)

● EmbeddedICE RT and embedded trace interfaces

● USB 2.0 Full-speed compliant device controller with 2 kB of endpoint RAM

● Single 10-bit DAC provides variable analog output

● Two 32-bit Timers/external event counters, PWM unit and watchdog

● Low power real-time clock (RTC) with independent power and 32kHz clock input

● Multiple serial interfaces including two UARTs (16C550), two Fast I2C-bus (400 Kbit/s), SPI and SSP

● Vectored interrupt controller (VIC) with configurable priorities and vector addresses

● Up to 45 of 5V tolerant fast general purpose I/O pins

● Up to 21 external interrupt pins available

● 60MHz Maximum CPU clock available from programmable on-chip PLL

● On-chip integrated oscillator operates with an external crystal from 1MHz to 25MHz

● Power saving modes include Idle and power-down

● Individual enable/disable of peripheral functions as well as peripheral clock scaling

● Processor wake-up from Power-down mode via external interrupt or BOD
