LPC2926/2927/2929
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
μ
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
μ
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 104 general-purpose I/O pins with programmable pull-up, pull-down, or bus
keeper.
Vectored Interrupt Controller (VIC) with 16 priority levels.
Up to 21 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; CAN or LIN activity.
Flexible Reset Generator Unit (RGU) able to control resets of individual modules.
Flexible Clock-Generation Unit (CGU0) 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 CGU (CGU1) 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.
144-pin LQFP package.
