4.2 IRC.2: Accuracy of the Internal RC Oscillator (IRC) frequency for
5.1 Note.1
devices only with date codes 0949 and before are outside of the
4 MHz +/ 1 % specification only at temperatures between 20 C and
40 C
Introduction:
The device has a 4 MHz internal RC oscillator (IRC) which can be optionally used as the
clock source for the Watch Dog Timer (WDT), and/or as the clock that drives the PLL and
subsequently the CPU. The IRC frequency spec is 4 MHz +/ 1 % accuracy over the
entire voltage and temperature range. During In-System Programming (ISP), the
auto-baud routine is expecting the IRC frequency to be 4 MHz +/ 1 % and is used to
synchronize with the host via serial port 0.
Problem:
On the LPC2478 Rev D device (only with date codes 0949 and before), the accuracy of
internal RC oscillator (IRC) frequency does not meet the 4 MHz +/ 1 % specification for
temperatures between 20 C and 40 C and the accuracy of internal RC oscillator (IRC)
frequency is 4 MHz +/ 5 % instead. As a result, only at these temperatures, this may
affect the auto-baud routine's ability to synchronize with the host via serial port 0 during
In-System Programming (ISP) at higher baud rates. For temperatures above 20 C, the
accuracy of internal RC oscillator (IRC) frequency meets the 4 MHz +/ 1 % specification.
Work-around:
None
On each of the following port pins P0.23, P0.24, P0.25, P0.26, P1.30, P1.31, P0.12, and
P0.13 (when configured as general purpose input pin (s)), leakage current increases
when the input voltage is Vi V
less than 4 mA by using a series limiting resistor.
