This is a datasheet for USB (12Mbps) function CY7C64013C CY7C64113C
The CY7C64013C and CY7C64113C are 8‑bit full‑speed USB microcontrollers offering 8 KB of PROM, 256 bytes of RAM, and integrated USB transceivers. They support an external 6‑MHz crystal, an internal PLL that generates 6, 12 and 48 MHz clocks, and include a 12‑bit free‑running timer, watchdog, and power‑on reset.
The devices provide multiple I/O options: three GPIO ports (Port 0‑2) with 7 mA typical sink current per pin, a fourth GPIO port (Port 3) with 12 mA sink capability, and a DAC port with programmable current‑sink outputs. Additional interfaces include an I²C‑compatible controller, a hardware‑assisted parallel interface (HAPI), and full USB‑1.1 compliance with up to five configurable endpoints.
