General description
Semiconductors designed LPC2478 microcontroller, powered ARM7TDMI-S core, highly integrated microcontroller wide range applications that require advanced communications high quality graphic displays. LPC2478 microcontroller on-chip high-speed flash memory. This flash memory includes special 128-bit wide memory interface accelerator architecture that enables execute sequential instructions from flash memory maximum system clock rate. This feature available only LPC2000 microcontroller family products. LPC2478, with real-time debug interfaces that include both JTAG embedded trace, execute both 32-bit 16-bit Thumb instructions. LPC2478 microcontroller incorporates controller, 10/100 Ethernet Media Access Controller (MAC), full-speed Device/Host/OTG Controller with endpoint RAM, four UARTs, Controller Area Network (CAN) channels, interface, Synchronous Serial Ports (SSP), three interfaces, interface. Supporting this collection serial communications interfaces following feature components; on-chip internal oscillator, total consisting local SRAM, SRAM Ethernet, SRAM general purpose DMA, battery powered SRAM, External Memory Controller (EMC). These features make this device optimally suited portable electronics Point-of-Sale (POS) applications. Complementing many serial communication controllers, versatile clocking capabilities, memory features various 32-bit timers, 10-bit ADC, 10-bit DAC, units, fast GPIO lines. LPC2478 connects GPIO pins hardware based Vector Interrupt Controller (VIC) that means these external inputs generate edge-triggered interrupts. these features make LPC2478 device particularly suitable industrial control medical systems.

Timer designed count cycles system derived clock optionally switch pins, generate interrupts perform other actions when specified timer values occur, based seven match registers. function addition these features based match register events. ability separately control rising falling edge locations allows used more applications. instance, multi-phase motor control typically requires three non-overlapping outputs with individual control three pulse widths positions. match registers used provide single edge controlled output. dedicated match register controls cycle rate, resetting count upon match. other match register controls edge position. Additional single edge controlled outputs require only match register each, since repetition rate same outputs. Multiple single edge controlled outputs will have rising edge beginning each cycle, when PWMMR0 match occurs. Three match registers used provide output with both edges controlled. Again, dedicated match register controls cycle rate. other match registers control edge positions. Additional double edge controlled outputs require only match registers each, since repetition rate same outputs. With double edge controlled outputs, specific match registers control rising falling edge output. This allows both positive going pulses (when rising edge occurs prior falling edge), negative going pulses (when falling edge occurs prior rising edge).

7.26.3 Wake-up timer
LPC2478 begins operation power-up when awakened from Power-down mode using oscillator clock source. This allows chip operation resume quickly. main oscillator needed application, software will need enable these features wait them stabilize before they used clock source. When main oscillator initially activated, wake-up timer allows software ensure that main oscillator fully functional before processor uses clock source starts execute instructions. This important power types Reset, whenever aforementioned functions turned reason. Since oscillator other functions turned during Power-down mode, wake-up processor from Power-down mode makes wake-up Timer. Wake-up Timer monitors crystal oscillator check whether safe begin code execution. When power applied chip, when some event caused chip exit Power-down mode, some time required oscillator produce signal sufficient amplitude drive clock logic. amount time depends many factors, including rate VDD(3V3) ramp case power on), type crystal electrical characteristics quartz crystal used), well other external circuitry (e.g., capacitors), characteristics oscillator itself under existing ambient conditions.

This allows trade-off power versus processing speed based application requirements. addition, Peripheral power control allows shutting down clocks individual on-chip peripherals, allowing fine tuning power consumption eliminating dynamic power peripherals that required application. Each peripherals clock divider which provides even better power control.
LPC2478 also implements separate power domain order allow turning power bulk device while maintaining operation small SRAM, referred Battery RAM. 7.26.4.1 Idle mode Idle mode, execution instructions suspended until either Reset interrupt occurs. Peripheral functions continue operation during Idle mode generate interrupts cause processor resume execution. Idle mode eliminates dynamic power used processor itself, memory systems related controllers, internal buses. 7.26.4.2 Sleep mode Sleep mode, oscillator shut down chip receives internal clocks. processor state registers, peripheral registers, internal SRAM values preserved throughout Sleep mode logic levels chip pins remain static. output disabled powered down fast wake-up later. oscillator stopped because interrupts used wake-up source. automatically turned disconnected. CCLK clock dividers automatically reset zero. Sleep mode terminated normal operation resumed either Reset certain specific interrupts that able function without clocks. Since dynamic operation chip suspended, Sleep mode reduces chip power consumption very value. flash memory left Sleep mode, allowing very quick wake-up. wake-up Sleep mode, used before entering Sleep mode, code execution peripherals activities will resume after cycles expire. main external oscillator used, code execution will resume when 4096 cycles expire. customers need reconfigure clock dividers accordingly. 7.26.4.3 Power-down mode Power-down mode does everything that Sleep mode does, also turns oscillator flash memory. This saves more power, requires waiting resumption flash operation before execution code data access flash memory accomplished. wake-up Power-down mode, used before entering Power-down mode, will take start-up. After this cycles will expire before code execution then resumed code running from SRAM. meantime, flash wake-up timer then counts clock cycles make flash start-up time. When times out, access flash will allowed. customers need reconfigure clock dividers accordingly.

LPC2478 provides independent power domains that allow bulk device have power removed while maintaining operation Battery RAM.
LPC2478, pads powered (VDD(3V3)) pins, while VDD(DCDC)(3V3) pins power on-chip DC-to-DC converter which turn provides power most peripherals. Although both ring core require supply, different powering schemes used depending actual application requirements. first option assumes that power consumption concern design ties VDD(3V3) VDD(DCDC)(3V3) pins together. This approach requires only power supply both pads, CPU, peripherals. While this solution simple, does support powering down ring fly" while keeping peripherals alive.
second option uses power supplies; supply pads (VDD(3V3)) dedicated supply (VDD(DCDC)(3V3)). Having on-chip DC-DC converter powered independently from ring enables shutting down power supply fly", while peripherals stay active. VBAT supplies power only Battery RAM. These functions require minimum power operate, which supplied external battery. When rest chip functions stopped power removed, supply alarm output that used external hardware restore chip power resume operation.
