LPC11U2x
32-bit ARM Cortex-M0 microcontroller
[2]
The typical frequency spread over processing and temperature (Tamb = 40 C to +85 C) is 40 %.
[3]
See the LPC11Uxx user manual.
10.4 I/O pins
[1]
Applies to standard port pins and RESET pin.
10.5 I2C-bus
[1]
See the I2C-bus specification UM10204 for details.
[2]
Parameters are valid over operating temperature range unless otherwise specified.
[3]
A device must internally provide a hold time of at least 300 ns for the SDA signal (with respect to the VIH(min) of the SCL signal) to
bridge the undefined region of the falling edge of SCL.
[4]
Cb = total capacitance of one bus line in pF.
[5]
The maximum tf for the SDA and SCL bus lines is specified at 300 ns. The maximum fall time for the SDA output stage tf is specified at
250 ns. This allows series protection resistors to be connected in between the SDA and the SCL pins and the SDA/SCL bus lines
without exceeding the maximum specified tf.
[6]
In Fast-mode Plus, fall time is specified the same for both output stage and bus timing. If series resistors are used, designers should
allow for this when considering bus timing.
