LPC11U6x v.1.2 20140526 Product data sheet - LPC11U6x v.1.1
Modifications:
• Part marking updated with revision indicator.
• Changed recommendation for VBAT connection if unused: Tie to VDD. See Table 3
“Pin description”.
• Section 14.7 “Connecting power, clocks, and debug functions” added.
• Section 14.9 “Pin states in different power modes” added.
• Remark added about using the regulator in the USB bus-powered set-up. See Section
14.3 “Suggested USB interface solutions”.
• Figure 39 “USB interface on a bus-powered device” changed to show USB_VBUS
connection to part.
• Parts added: LPC11U67JBD100, LPC11U67JBD64, LPC11U66JBD48.
LPC11U6x v.1.1 20140312 Product data sheet - LPC11U6x v.1
Modifications:
• Parameter R
I
renamed to Z
I
(input impedance) in Table 22.
• Description of the internal USB_CONNECT function clarified in Section 14.3
“Suggested USB interface solutions”. The USB_CONNECT function can be set
internally by software and does not require external circuitry.
• Parameter Cia corrected in Table 22 “12-bit ADC static characteristics”.
• Figure 36 “ADC input impedance” added.
• Parameter pin capacitance added in Table 8.
• Pin description for VBAT updated: If no battery is used, tie VBAT to VDD or to ground.
See Table 3.
• Pin description for RESET/PIO0_0 updated: In deep power-down mode, this pin must
be pulled HIGH externally. The RESET
pin can be left unconnected or be used as a
GPIO pin if an external RESET function is not needed. See Table 3.
• Pin functions TMS, TDI, TDO, and TRST changed to default function in Table 3.
• Pin description table updated for clarity (VBAT, I2C-bus pins, WAKEUP pin).
• Section 14.1 “ADC usage notes” added.
• Use of USB_CONNECT signal explained when VBUS is not connected. See
Section 14.3.
