DALLAS, TEXAS 75265
NOTES: A. During programming activity and when blowing the JTAG enable fuse, the TDI/VPP terminal is used to apply the correct voltage
source. The TDO/TDI terminal is used to apply the test input data for JTAG circuitry.
B. The TDI/VPP terminal of the ’P337A and ’E337A does not have an internal pullup resistor. An external pulldown resistor is
recommended to avoid a floating node, which could increase the current consumption of the device.
Remove the external pulldown
resistors when switching from P/E337A to C337 devices. Otherwise system power consumption will increase.
C. The TDO/TDI terminal is in a high-impedance state after POR. The ’P337A and ’E337A need a pullup or a pulldown resistor to
avoid floating a node, which could increase the current consumption of the device.
D. The pullup resister is only implemented in C-version
