I2c Implemented From 6 Pin Pic?, need external open drain transistors?

[treez]

Hello,

I am wanting to interface an MCP4706 DAC to a PIC10F200

MCP4706 DAC datasheet

PIC10F200 DATASHEET
http://ww1.microchip.com/downloads/en/devicedoc/41239a.pdf

Will i need to add external open collector BJTs to the PIC10F200 to act as outputs, and use a separate input pin on the pIC10F200?

...Or is it simply not going to be possible to interface the PIC10F200 to the MCP4706, since PIC10F200 does not have an I2C module?

I am going to use "bit-bashing" to communicate with the MCP4706 because there is no I2C module on the PIC10F200.

Only needs one pin for each line. Set the pin as input, when idle/reading, and output, low, when outputting.. right?
