This document is the user manual for CY7C63411/12/13 CY7C63511/12/13 Low-Speed, High I/O, 1.5 Mbps USB Controller
The CY7C63411/12/13 and CY7C63511/12/13 are 8‑bit RISC microcontrollers that integrate a low‑speed USB serial interface engine, 24‑GPIO pins plus an optional DAC port, and a 12‑bit free‑running timer. They support USB HID, PS/2 operation, and provide programmable current‑sink outputs for high‑current I/O.
The devices are offered in multiple EPROM sizes (4 KB, 6 KB, 8 KB) and package types (40‑pin PDIP, 48‑pin SSOP, windowed variants). Key features include a 6 MHz external ceramic resonator, 12 MHz internal CPU clock, 256 bytes of RAM, and operating voltage from 4.0 V to 5.5 V.
