I've never had my hands on a PNX4008 chip at NXP, but I do believe they are the same IP. That specific I2C IP was used in a number of NXP/Phillips chips besides the PNX4008/LPC32xx. I don't think there are any PNX4008's in the wild, and even working in NXP, I can't find any non-marketing reference material for that part (including the user manual). The pnx I2C block is used in the LPC32xx (3 instances), the LPC313x, LPC2000 (1 instance for USB OTG), and the LPC17xx/LPC40xx (1 instance for USB OTG). The LPC2000, LPC17xx, and LPC40xx devices also use another completely different (non-pnx) I2C block for non-OTG I2C. ????{.n?+???????+%?????ݶ??w??{.n?+????{??G?????{ay?ʇڙ?,j??f???h?????????z_??(?階?ݢj"???m??????G????????????&???~???iO???z??v?^?m???? ????????I?
