LPC2148FBD64,118 Description

The LPC2148FBD64,118 is a microcontroller based on a 16-bit/32-bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, that combines the microcontroller with embedded high-speed flash memory ranging from 32 kB to 512 kB. A 128-bit wide memory interface and a unique accelerator architecture enable 32-bit code execution at the maximum clock rate. 

LPC2148FBD64,118 Features

• 16-bit/32-bit ARM7TDMI-S microcontroller in a tiny LQFP64 package.

• 8 kB to 40 kB of on-chip static RAM and 32 kB to 512 kB of on-chip flash memory. 128-bit wide interface/accelerator enables high-speed 60 MHz operations.

• In-System Programming/In-Application Programming (ISP/IAP) via on-chip boot loader software. Single flash sector or full chip erase in 400 ms and programming of 256 B in 1 ms. 

• EmbeddedICE RT and Embedded Trace interfaces offer real-time debugging with the on-chip RealMonitor software and high-speed tracing of instruction execution.

• USB 2.0 Full-speed compliant device controller with 2 kB of endpoint RAM. In addition, the LPC2146/48 provides 8 kB of on-chip RAM accessible to USB by DMA.

• One or two (LPC2141/42 vs. LPC2144/46/48) 10-bit ADCs provide a total of 6/14 analogue inputs, with conversion times as low as 2.44 ?s per channel.

• A single 10-bit DAC provides variable analogue output (LPC2142/44/46/48 only).

• Two 32-bit timers/external event counters (with four capture and four compare channels each), PWM unit (six outputs) and watchdog.

• Low-power Real-Time Clock (RTC) with independent power and 32 kHz clock input

• Multiple serial interfaces including two UARTs (16C550), two Fast I2C-bus (400 kbit/s), SPI and SSP with buffering and variable data length capabilities.

•  Vectored Interrupt Controller (VIC) with configurable priorities and vector addresses.

• Up to 45 of 5 V tolerant fast general purpose I/O pins in a tiny LQFP64 package.

• Up to 21 external interrupt pins are available.

• 60 MHz maximum CPU clock available from programmable on-chip PLL with a settling time of 100 μs.

• The on-chip integrated oscillator operates with an external crystal from 1 MHz to 25 MHz.

• Power saving modes include Idle and Power-down.

• Individual enables/disables peripheral functions as well as peripheral clock scaling for additional power optimization.

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