LPC11U3X v.2.2 20140311 Product data sheet - LPC11U3X v.2.1
Modifications:
• Use of USB_CONNECT signal explained in Section 11.1 “Suggested USB interface
solutions”.
• Open-drain I
2
C-bus and RESET pin descriptions clarified. See Table 3.
LPC11U3X v.2.1 20131230 Product data sheet - LPC11U3X v.2
Modifications: Add reserved function to pins PIO0_8/MISO0/CT16B0_MAT0/R/IOH_6 and
PIO0_9/MOSI0/CT16B0_MAT1/R/IOH_7.
LPC11U3X v.2 20131125 Product data sheet - LPC11U3X v.1.1
Modifications:
• Part LPC11U37HFBD64/401 with I/O handler added.
• Additional I/O Handler pin functions added in Table 3.
• Typical range of watchdog oscillator frequency changed to 9.4 kHz to
2.3 MHz.See Table 13.
• Section 11.8 “I/O Handler software library applications” added.
• Updated Section 11.1 “Suggested USB interface solutions” for clarity.
• Condition V
DD
= 0 V added to Parameter V
I
in Table 5 for clarity.
LPC11U3X v.1.1 20130924 Product data sheet - LPC11U3X v.1
Modifications:
• Removed the footnote “The peak current is limited to 25 times the
corresponding maximum current.” in Table 4.
• Table 3: Added “5 V tolerant pad” to RESET/PIO0_0 table note.
• Table 7: Removed BOD interrupt level 0.
• Programmable glitch filter is enabled by default. See Section 7.7.1.
• Added Section 11.6 “ADC effective input impedance”.
• Table 5 “Static characteristics” added Pin capacitance section.
• Updated Section 11.1 “Suggested USB interface solutions”.
• Table 4 “Limiting values”:
– Updated V
DD
min and max.
– Updated V
I
conditions.
• Table 10 “EEPROM characteristics”:
– Removed f
clk
and t
er
; the user does not have control over these
parameters.
– Changed the t
prog
from 1.1 ms to 2.9 ms; the EEPROM IAP always
does an erase and program, thus the total program time is t
er
+ t
prog
.
• Changed title of Figure 29 from “USB interface on a self-powered
device” to “USB interface with soft-connect”.
• Section 10.7 “USB interface” added. Parameter t
EOPR1
and t
EOPR2
renamed to t
EOPR
.
