LPC3220/30/40/50

16/32-bit ARM microcontrollers

 Six enhanced timer/counters which are architecturally identical except for the

peripheral base address. Two capture inputs and two match outputs are pinned out

to four timers. Timer 1 brings out a third match output, timers 2 and 3 bring out all

four match outputs, timer 4 has one match output, and timer 5 has no inputs or

outputs.

 32-bit millisecond timer driven from the RTC clock. This timer can generate

interrupts using two match registers.

 WatchDog timer clocked by the peripheral clock.

 Two single-output PWM blocks.

 Motor control PWM.

 Keyboard scanner function allows automatic scanning of an up to 8

 8 key matrix.

 Up to 18 external interrupts.

 Standard ARM test/debug interface for compatibility with existing tools.

 Emulation Trace Buffer (ETB) with 2048

 24 bit RAM allows trace via JTAG.

 Stop mode saves power while allowing many peripheral functions to restart CPU

activity.

 On-chip crystal oscillator.

 An on-chip PLL allows CPU operation up to the maximum CPU rate without the

requirement for a high frequency crystal. Another PLL allows operation from the

32 kHz RTC clock rather than the external crystal.

 Boundary scan for simplified board testing.

 User-accessible unique serial ID number for each chip.

 TFBGA296 package with a 15 mm

 15 mm  0.7 mm body.

Applications

 Consumer

 Medical

 Industrial

 Network control
