16/32-bit ARM microcontroller with external memory interface
USB_DAT_VP — USB transmit data
U5_RX — UART 5 receive data input
serial clock for USB I
serial data for USB I
USB transmit enable for DAT/SE0
USB_SE0_VM — USB single ended zero transmit
U5_TX — UART 5 transmit data output
1.2 V power supply for various internal functional blocks that are
not included with VDD_CORE or VDD_COREFXD
3.0 V power supply and positive reference voltage for the ADC
1.2 V core main power supply for the CPU and other core logic;
this voltage may be reduced to 0.9 V when the core is running at
or below 13 MHz; the HIGHCORE pin may be used to signal this
condition to an external voltage switch
1.2 V core secondary power supply voltage for the CPU and other
core logic; this supply cannot be reduced in the same manner as
the VDD_CORE12 supply
1.8 V or 3.0 V power supply for I/O pins that may operate from
either a 1.8 V range or a 3 V range
1.8 V power supply for I/O pins that operate only from a 1.8 V
range
3.0 V power supply for I/O pins that operate only from a 3 V range
1.2 V power supply for the main oscillator
1.2 V power supply for the 397x PLL
1.2 V power supply for the HCLK PLL
1.2 V power supply for the USB PLL
1.2 V power supply for the RTC block
1.2 V power supply for the RTC block
1.2 V power supply for the 32 kHz RTC oscillator
1.8 V power supply for the SDRAM controller block
ground for various internal logic blocks that are not included with
VDD_CORE or VDD_COREFXD.
ground for the ADC; this should nominally be the same voltage as
VSS, but should be isolated to minimize noise and conversion
error
