LPC2377/78
Single-chip 16-bit/32-bit microcontrollers
On-chip crystal oscillator with an operating range of 1 MHz to 25 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.
On-chip PLL allows CPU operation up to the maximum CPU rate without the need for
a high frequency crystal. Can be run from the main oscillator, the internal RC oscillator,
or the RTC oscillator.
Boundary scan for simplified board testing.
Versatile pin function selections allow more possibilities for using on-chip peripheral
functions.
