ATF150x Programmers based on FT232H modules

ATF150x programmer in the form of a "hat" PCB for common FT232H USB modules like CJMCU-232H or Adafruit 2264.

Includes a 12V supply for VPP on /OE1 to recover CPLDs that have JTAG disabled.

There are 2 versions. Both versions provide:

• FT232H
• 10-pin JTAG port with ATMEL/ALtera JTAG-A pinout
• 12V power supply for VPP
• Optional 12V VPP out on JTAG pin 6
• JTAG VCC switchable:
  • programmer supplies 3V3 VCC to target
  • programmer supplies 5V VCC to target
  • target supplies own VCC

The Adafruit 2264 version:

• USB-C
• Connect to 2264 without sockets
• Slide switches to select options
• Leds to show USB, VCC, VPP
• 33 ohm resistors on JTAG data lines
• Smaller

The CJMCU-232H version:

• USB-A
• PLCC-44 socket
• Jumpers to select options
• Cheaper (232H board from aliexpress)

CJMCU-232H

VPP-over-JTAG

When VPP is ON, 12V is supplied to JTAG pin 6 and PLCC pin 44.
This forces the JTAG pins to be enabled even if the device is currently programmed with the JTAG pins disabled (used as ordinary I/O pins).

ATF150x_uDEV includes a matching option to receive VPP on JTAG pin 6.

JTAG pin 6 should normally be NC for most Altera JTAG-A targets, but 12V is 12V, so Don't enable VPP with an unknown device connected to JTAG
