Today I finally received my new (noname) development board for the Cypress CY7C68013A MCU.
It features the CY7C68013A-56PVXC, a mini-USB port, the AMS1117-3.3 3.3 Volt LDO, a 24 MHz crystal, the Atmel ATMTC169-24C128N EEPROM, two buttons, two jumpers, two LEDs plus power LED and two 2×10 pin 2.54mm headers breaking out the MCU’s pins.
Read more about fxload in my next post.
For firmware development there exists a library called fx2lib.
Also interesting to know: The Sigrok FX2lafw firmware enables using this MCU and board as logic analyzer and cheap oscilloscope:
The board isn’t a new product or design, nor is the MCU. But it can still be found in products, e.g. on the Spartan-3E starter kit, where it functions as USB interface respectively CPLD and FPGA programmer.
People have written about the board, e.g.:
Thanks you, Peter! He also has a board schematic on his blog post (I didn’t find a better image quality, sorry, but it’s readable with a little effort):
Missing in this schematic are the LEDs though (on the top right in the first picture), which are:
- LED D1, connected to PA0, active low
- LED D2, connected to PA1, active low
- Jumper J1: Enables 3V3 on D1 and D2
- Jumper J2: Connected to EEPROM but unclear function:
- Enable/Disable EEPROM power supply?
- EEPROM Write-Protection?
- Select EEPROM memory region?
- Select EEPROM’s I2C address?
