JTAG Boundary Scan Port

Overview
Each iCE65 device includes an IEEE 1149.1-compatible JTAG boundary-scan port. The port supports printed-circuit
board (PCB) testing and debugging. It also provides an alternate means to configure the iCE65 device.
Signal Connections
Table 31
the Application Processor’s (AP) I/O supply rail and the iCE65’s SPI and VCCIO_2 bank supply rails all connect to
the same voltage. The second scenario is when the AP’s I/O supply voltage is greater than the iCE65’s VCCIO_2
supply voltage.
The JTAG port connections are listed in

package types. The JTAG port is located in I/O Bank 1 along the right edge of the iCE65 device and powered by the
VCCIO_1 supply inputs. Consequently, the JTAG interface uses the associated I/O standards for I/O Bank 1.

Description
AP can directly drive CRESET_B High and
Low although an open-drain output
recommended is if multiple devices control
CRESET_B. If using an open-drain driver,
the CRESET_B input must include a 10 kΩ
pull-up resistor to VCCIO_2. The 10 kΩ
pull-up resistor to AP_VCCIO is also
recommended.
The AP must control CRESET_B with an
open-drain output, which requires a 10 kΩ
pull-up resistor to VCCIO_2. The 10 kΩ
pull-up resistor to AP_VCCIO is required.
