Microcontroller Overview Quiz

Microcontroller Overview

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

Memory and Interface

• 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 operation.

Programming and Debugging

• 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 bytes 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 and Analog Features

• USB 2.0 Full-speed compliant device controller with 2 kB of endpoint RAM.
• 8 kB of on-chip RAM accessible to USB by DMA.
• One or two 10-bit ADCs provide a total of 6/14 analog inputs, with conversion times as low as 2.44 ms per channel.
• Single 10-bit DAC provides variable analog output (LPC2142/44/46/48 only).

Timers, Counters, and Watchdog

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

Clock and Power Management

• Low power Real-Time Clock (RTC) with independent power and 32 kHz clock input.
• 60 MHz maximum CPU clock available from programmable on-chip PLL with settling time of 100 ms.
• On-chip integrated oscillator operates with an external crystal from 1 MHz to 25 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.

Interrupt and I/O

• 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 available.

Power Supply

• Single power supply chip with POR and BOD circuits.
• CPU operating voltage range of 3.0 V to 3.6 V (3.3 V ± 10 %) with 5 V tolerant I/O pads.
