1. General description

The LPC2364/66/68 mICrocontrollers are based on a 16-bit/32-bit ARM7TDMI-S CPU with

real-time emulation that combines the microcontroller with up to 512 kB of embedded

high-speed flash memory. A 128-bit wide memory interface and a unique accelerator

architecture enable 32-bit code execution at the maximum clock rate. For critical

performance in interrupt service routines and DSP algorithms, this increases performance

up to 30 % over Thumb mode. For critical code size applications, the alternative 16-bit

Thumb mode reduces code by more than 30 % with minimal performance penalty.

The LPC2364/66/68 are ideal for multi-purpose serial communication applications. They

incorporate a 10/100 Ethernet Media Access Controller (MAC), USB full speed device

with 4 kB Endpoint RAM, four UARTs, two CAN channels, an SPI interface, two

Synchronous Serial Ports (SSP), three I2C interfaces, and an I2S interface. This blend of

serial communications interfaces combined with an on-chip 4 MHz internal oscillator,

SRAM of up to 32 kB, 16 kB SRAM for Ethernet, 8 kB SRAM for USB and general

purpose use, together with 2 kB battery powered SRAM make these devices very well

suited for communication gateways and protocol converters. Various 32-bit timers, an

improved 10-bit ADC, 10-bit DAC, one PWM unit, a CAN control unit, and up to 70 fast

GPIO lines with up to 12 edge or level sensitive external interrupt pins make these

microcontrollers particularly suitable for industrial control and medical systems.

2. Features

? ARM7TDMI-S processor, running at up to 72 MHz.

? Up to 512 kB on-chip Flash Program Memory with In-System Programming (ISP) and

In-Application Programming (IAP) capabilities. Flash program memory is on the ARM

local bus for high performance CPU access.

? 8/32 kB of SRAM on the ARM local bus for high performance CPU access.

? 16 kB SRAM for Ethernet interface. Can also be used as general purpose SRAM.

? 8 kB SRAM for general purpose DMA use also accessible by the USB.

? Dual AHB system that provides for simultaneous Ethernet DMA, USB DMA, and

program execution from on-chip Flash with no contention between those functions. A

bus bridge allows the Ethernet DMA to access the other AHB subsystem.

? Advanced Vectored Interrupt Controller, supporting up to 32 vectored interrupts.

? General Purpose AHB DMA controller (GPDMA) that can be used with the SSP serial

interfaces, the I2S port, and the SD/MMC card port, as well as for memory-to-memory

transfers.

? Serial Interfaces:

Fast communication chip

? Ethernet MAC with associated DMA controller. These functions reside on an

independent AHB bus.

? USB 2.0 Full-Speed Device with on-chip PHY and associated DMA controller.

? Four UARTs with fractional baud rate generation, one with modem control I/O, one

with IrDA support, all with FIFO.

? CAN controller with two channels.

? SPI controller.

? Two SSP controllers, with FIFO and multi-protocol capabilities. One is an alternate

for the SPI port, sharing its interrupt and pins. These can be used with the GPDMA

controller.

? Three I2C-bus interfaces (one with open-drain and two with standard port pins).

? I

2S (Inter-IC Sound) interface for digital audio input or output. It can be used with

the GPDMA.

? Other Peripherals:

? Secure Digital (SD) / MultiMediaCard (MMC) memory card interface (LPC2368

only).

? 70 General purpose I/O pins with configurable pull-up/down resistors.

? 10-bit ADC with input multiplexing among 6 pins.

? 10-bit DAC.

? Four general purpose Timers/Counters with total of 8 capture inputs and 10

compare outputs. Each Timer BLOCK has an external count input.

? One PWM / Timer block with support for three-phase motor control. The PWM has

two external count inputs.

? Real Time Clock with separate power pin, clock source can be the RTC oscillator or

the APB clock.

? 2 kB SRAM powered from the RTC power pin, allowing data to be stored when the

rest of the chip is powered off.

? Watchdog Timer. The watchdog timer can be clocked from the internal RC

oscillator, the RTC oscillator, or the APB clock.

? Standard ARM Test/Debug interface for compatibility with existing tools.

? Emulation Trace Module supports real-time trace.

? Single 3.3 V power supply (3.0 V to 3.6 V).

? Four reduced power modes, Idle, Sleep, Power Down, and Deep Power down.

? Four external interrupt inputs configurable as edge/level sensitive. All pins on PORT0

and PORT2 can be used as edge sensitive interrupt sources.

? Processor wake-up from Power-down mode via any interrupt able to operate during

Power-down mode (includes external interrupts, RTC interrupt, USB activity, Ethernet

wake-up interrupt).

? Two independent power domains allow fine tuning of power consumption based on

needed features.

? Each peripheral has its own clock divider for further power saving.

? Brownout detect with separate thresholds for interrupt and forced reset.

? On-chip Power On Reset.

? On-chip crystal oscillator with an operating range of 1 MHz to 24 MHz.

? 4 MHz internal RC oscillator trimmed to 1 % accuracy that can optionally be used as

the system clock. When used as the CPU clock, does not allow CAN and USB to run
