LPC2939
ARM9 microcontroller with CAN, LIN, and USB
Other peripherals:
One 10-bit ADC with 5.0 V measurement range and eight input channels with
conversion times as low as 2.44
s per channel
Two 10-bit ADCs, 8-channels each, with 3.3 V measurement range provide an
additional 16 analog inputs with conversion times as low as 2.44
s per channel.
Each channel provides a compare function to minimize interrupts.
Multiple trigger-start option for all ADCs: timer, PWM, other ADC, and external
signal input
Four 32-bit timers each containing four capture-and-compare registers linked to
I/Os
Four six-channel PWMs (Pulse-Width Modulators) with capture and trap
functionality
Two dedicated 32-bit timers to schedule and synchronize PWM and ADC
Quadrature encoder interface that can monitor one external quadrature encoder
32-bit watchdog with timer change protection, running on safe clock
Up to 152 general-purpose I/O pins with programmable pull-up, pull-down, or bus
keeper
Vectored Interrupt Controller (VIC) with 16 priority levels
Up to 22 level-sensitive external interrupt pins, including USB, CAN and LIN wake-up
features
Configurable clock-out pin for driving external system clocks
Processor wake-up from power-down via external interrupt pins and CAN or LIN
activity
Flexible Reset Generator Unit (RGU) able to control resets of individual modules
Flexible Clock-Generation Unit (CGU) able to control clock frequency of individual
modules:
On-chip very low-power ring oscillator; fixed frequency of 0.4 MHz; always on to
provide a Safe_Clock source for system monitoring
On-chip crystal oscillator with a recommended operating range from 10 MHz to
25 MHz. PLL input range 10 MHz to 25 MHz.
On-chip PLL allows CPU operation up to a maximum CPU rate of 125 MHz
Generation of up to 11 base clocks
Seven fractional dividers
Second, dedicated CGU with its own PLL generates USB clocks and a configurable
clock output
Highly configurable system Power Management Unit (PMU):
clock control of individual modules
allows minimization of system operating power consumption in any configuration
Standard ARM test and debug interface with real-time in-circuit emulator
Boundary-scan test supported
ETM/ETB debug functions with 8 kB of dedicated SRAM also accessible for
application code and data storage
Dual power supply:
CPU operating voltage: 1.8 V
5 %
I/O operating voltage: 2.7 V to 3.6 V; inputs tolerant up to 5.5 V
208-pin LQFP package
