LPC2148
Description
The LPC2142/2148 microcontrollers are based on a 32/16-bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, that bines the microcontroller with 64 kB and 512 kB of embedded high-speed flash memory.
Key Features
- 2.1 Key features
- One or two (LPC2142/48) 10-bit ADCs provide a total of 6/14 analog inputs, with conversion times as low as 2.44 µs per channel
- Single 10-bit DAC provides variable analog output
- Low power Real-Time Clock (RTC) with independent power and dedicated 32 kHz clock input
- 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 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
