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 memo ry 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-purpos e serial communication applications. they incorporate a 10/100 ethernet media access controller (mac), usb full speed device with 4 kb endpoint ram, four uarts, tw o can channels, an spi interface, two synchronous serial ports (ssp), three i 2 c interfaces, and an i 2 s interface. this blend of serial communications interfac es 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 pow ered 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 fo r 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 (i ap) 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 simu ltaneous ethernet dma, usb dma, and program execution from on-chip flash with no contention betwee n 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 i 2 s port, and the sd/mmc card port, as well as for memory-to-memory transfers. ? serial interfaces: lpc2364/66/68 single-chip 16-bit/32-bit microco ntrollers; up to 512 kb flash with isp/iap, ethernet, usb 2.0, can, and 10-bit adc/dac rev. 01 ? 22 september 2006 preliminary data sheet

lpc2364_66_68_1 ? koninklijke philips electronics n.v. 2006. all rights reserved. preliminary data sheet rev. 01 ? 22 september 2006 28 of 48 philips semiconductors lpc2364/2366/2368 fast communication chip whenever any of the aforemen tioned functions are turned off for any reason. since the oscillator and other functions are turned off during power-down mode, any wake-up of the processor from power-down mode makes use of the wake-up timer. the wake-up timer monitors the crystal oscilla tor to check whether it is safe to begin code execution. when power is applied to th e chip, or when some event caused the chip to exit power-down mode , some time is requir ed for the oscillator to produce a signal of sufficient amplitude to drive the clock logic. the amount of time depends on many factors, including the rate of v dd ramp (in the case of power on), the type of crystal and its electrical characteristics (if a quartz crystal is used), as well as any other external circuitry (e.g. capacitors), and the charac teristics of the oscillator itse lf under the existing ambient conditions. 7.24.4 power control the lpc2364/66/68 supports a variety of powe r control features. there are four special modes of processor power reduction: idle mode, sleep mode, power-down mode, and deep power-down mode. the cpu clock rate may also be controlled as needed by changing clock sources, re-con figuring pll values, and/or altering the cpu clock divider value. this allows a trade-off of power ve rsus processing speed based on application requirements. in addition, peripheral power control allows shutting down the clocks to individual on-chip peripherals, allowing fine tuning of power consumption by eliminating all dynamic power use in any peripherals that are no t required for the application. each of the peripherals has its own clock divider wh ich provides even better power control. the lpc2364/66/68 also implements a separate power domain in order to allow turning off power to the bulk of the device while ma intaining operation of the real time clock and a small sram, referred to as the battery ram. 7.24.4.1 idle mode in idle mode, execution of instructions is suspended until either a reset or interrupt occurs. peripheral functions continue opera tion during idle mode and may generate interrupts to cause the processor to resume execution. idle mode eliminates dynamic power used by the processor itself, memory systems and related controllers, and internal buses. 7.24.4.2 sleep mode in sleep mode, the oscillator is shut down an d the chip receives no internal clocks. the processor state and registers, peripheral registers, and internal sram values are preserved throughout sleep mode and the logic levels of chip pins remain static. the output of the irc is disabled but the irc is not powered down for a fast wake-up later. the 32 khz rtc oscillator is not stopped becaus e the rtc interrupts may be used as the wake-up source. the pll is automatically turned off and disconnected. the cclk and usb clock dividers automati cally get reset to zero. the sleep mode can be terminated and normal operation resumed by either a reset or certain specific interrupts that are able to function without clocks. since all dynamic operation of the chip is suspended, sleep mode reduces chip power consumption to a very low value. the flash memory is left on in sleep mode, allowing a very quick wake-up.
lpc2364_66_68_1 ? koninklijke philips electronics n.v. 2006. all rights reserved. preliminary data sheet rev. 01 ? 22 september 2006 29 of 48 philips semiconductors lpc2364/2366/2368 fast communication chip on the wake-up of sleep mode, if the irc was used before entering sleep mode, the code execution and peripherals activi ties will resume after 4 cycles expire. if the main external oscillator was used, the code executio n will resume when 4096 cycles expire. the customers need to reconfigure the pll and clock dividers accordingly. 7.24.4.3 power-down mode power-down mode does everyt hing that sleep mode does, but also turns off the irc oscillator and the flash memory. this save s more power, but r equires waiting for resumption of flash operation before execut ion of code or data access in the flash memory can be accomplished. on the wake-up of power-down mode, if the irc was used before entering power-down mode, it will take irc 60 s to start-up. after this 4 irc cycles will expire before the code execution can then be resumed if the code was running from sram. in the meantime, the flash wake-up timer then counts 4 mhz irc clock cycles to make the 100 s flash start-up time. when it times out, access to the flash will be allowed. the customers need to reconfigure the pll and clock dividers accordingly. 7.24.4.4 deep power-down mode deep power-down mode is like power-down mode, but the on-chip regulator that supplies power to internal logic is also shut off. this produces the lowest possible power consumption without actually removing po wer from the entire chip. since deep power-down mode shuts down the on-chip logic power supply, there is no register or memory retention, and resumption of operation involves the same activities as a full-chip reset. if power is supplied to the lpc2364/66/68 du ring deep power-down mode, wake-up can be caused by external reset. while in deep power-down mode, external device power may be removed. in this case, the lpc2364/66/68 will start up when external power is restored. essential data may be retained through deep power-down mode (or through complete powering off of the chip) by storing data in t he battery ram, as long as the external power to the vbat pin is maintained. 7.24.4.5 power domains the lpc2364/66/68 provides two independent power domains that allow the bulk of the device to have power removed while maintaining operation of the real time clock and the battery ram. the 3.3v (v dd(3v3) ) pins power both the on-chip dc-dc converter and the i/o pads. these pins provide the power for the cpu and most of the peripherals. if power is removed from the vdd pins, the cpu and related peripherals stop. the vbat pin supplies power only to the rtc and the battery ram. these two functions require a minimum of power to operate, whic h can be supplied by an external battery.
