ARM LPC2148 FEATURES

16/32-bit ARM7TDMI-S microcontroller in a tiny 64 package.

•         8 to 40 kB of on-chip static RAM and 32 to 512 kB of on-chip flash program memory [6].

•         128 bit wide interface/accelerator enables high speed 60 MHz operation.

•         In-System/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 bytes in 1 ms.

•         Embedded ICE RT and Embedded Trace interfaces offer real-time debugging with the on-chip Real Monitor 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 LPC2146/8 provides 8 kB of on-chip RAM accessible to USB by DMA.

•         One or two (LPC2141/2 vs. LPC2144/6/8) 10-bit A/D converters provide a total of 6/14

•         Analog inputs, with conversion times as low as 2.44 µs per channel.

•         Single 10-bit D/A converter provide variable analog output.

•         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 with independent power and dedicated 32 kHz clock input [6].

•         Multiple serial interfaces including two UARTs (16C550), two Fast I2C-buses

•         (400 Kbit/s), SPI and SSP with buffering and variable data length capabilities.

•         Vectored interrupt controller with configurable priorities and vector addresses.

•         Up to 45 of 5 V tolerant fast general purpose I/O pins in a tiny 64 package.

•         Up to nine edge or level sensitive external interrupt pins available.

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

•         On-chip integrated oscillator operates with an external crystal in range from 1 MHz to 30 MHz and with an external oscillator up to 50 MHz.

•         Power saving modes include idle and Power-down.

•         Individual enable/disable of peripheral functions as well as peripheral clock scaling for Additional power optimization.

•         Processor wake-up from Power-down mode via external interrupt, USB, Brown-Out Detect (BOD) or Real-Time Clock (RTC).
