CY7C63413C CY7C63513C CY7C63613C is a low-speed high I/O 1.5Mbps USB controller, suitable for low-speed applications such as keyboards, keyboards with integrated pointing devices, gamepads, etc. It conforms to USB 1.1 and 2.0 specifications, USB HID 1.1 specification, and features an integrated USB transceiver.
The Cypress CY7C63413C, CY7C63513C and CY7C63613C are low‑speed (1.5 Mbps) USB controllers with high I/O capability, designed for keyboards, gamepads and similar devices. They comply with USB 1.1/2.0 and HID specifications, include an integrated USB transceiver, and can auto‑configure for PS/2 operation.
Each device contains an 8‑bit RISC core, 256 bytes of RAM, 8 KB of EPROM, a 12‑MHz internal CPU clock (driven by a 6‑MHz external ceramic resonator), and a rich set of GPIO and DAC pins. The architecture provides a 12‑bit free‑running timer, watchdog timer, vectored interrupt controller and support for up to three USB data endpoints.
