LPC2468

Fast communication chip

I 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, CAN bus activity, port 0/2 pin interrupt).

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

needed features.

I Each peripheral has its own clock divider for further power saving. These dividers help

reducing active power by 20 % to 30 %.

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

I On-chip power-on reset.

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

I 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.

I On-chip PLL allows CPU operation up to the maximum CPU rate without the need for

a high frequency crystal. May be run from the main oscillator, the internal RC

oscillator, or the RTC oscillator.

I Boundary scan for simpliﬁed board testing.

I Versatile pin function selections allow more possibilities for using on-chip peripheral

functions.

Applications

I Industrial control

I Medical systems

I Protocol converter

I Communications
