LPC435x/3x/2x/1x

32-bit ARM Cortex-M4/M0 microcontroller



LCD controller with DMA support and a programmable display resolution of up to

1024 H

 768 V. Supports monochrome and color STN panels and TFT color

panels; supports 1/2/4/8 bpp Color Look-Up Table (CLUT) and 16/24-bit direct

pixel mapping. Available on parts LPC4357/53 only.



Secure Digital Input Output (SD/MMC) card interface.



Eight-channel General-Purpose DMA controller can access all memories on the

AHB and all DMA-capable AHB slaves.



Up to 164 General-Purpose Input/Output (GPIO) pins with configurable

pull-up/pull-down resistors.



GPIO registers are located on the AHB for fast access. GPIO ports have DMA

support.



Up to eight GPIO pins can be selected from all GPIO pins as edge and level

sensitive interrupt sources.



Two GPIO group interrupt modules enable an interrupt based on a programmable

pattern of input states of a group of GPIO pins.



Four general-purpose timer/counters with capture and match capabilities.



One motor control Pulse Width Modulator (PWM) for three-phase motor control.



One Quadrature Encoder Interface (QEI).



Repetitive Interrupt timer (RI timer).



Windowed watchdog timer (WWDT).



Ultra-low power Real-Time Clock (RTC) on separate power domain with 256 bytes

of battery powered backup registers.



Alarm timer; can be battery powered.



Analog peripherals



One 10-bit DAC with DMA support and a data conversion rate of 400 kSamples/s.



Two 10-bit ADCs with DMA support and a data conversion rate of 400 kSamples/s.

Up to eight input channels per ADC.



Unique ID for each device.



Clock generation unit



Crystal oscillator with an operating range of 1 MHz to 25 MHz.



12 MHz internal RC oscillator trimmed to 3 % accuracy over temperature and

voltage (1.5 % accuracy for Tamb = 0 °C to 85 °C).



Ultra-low power Real-Time Clock (RTC) crystal oscillator.



Three PLLs allow CPU operation up to the maximum CPU rate without the need for

a high-frequency crystal. The second PLL can be used with the High-speed USB,

the third PLL can be used as audio PLL.



Clock output.



Power



Single 3.3 V (2.4 V to 3.6 V) power supply with on-chip DC-to-DC converter for the

core supply and the RTC power domain.



RTC power domain can be powered separately by a 3 V battery supply.



Four reduced power modes: Sleep, Deep-sleep, Power-down, and Deep

power-down.



Processor wake-up from Sleep mode via wake-up interrupts from various

peripherals.
