Functional Overview

The CY7C630/1XXA is a family of 8-bit RISC One Time Programmable (OTP) microcontrollers with a built-in 1.5-Mbps USB Serial Interface Engine (SIE). The microcontroller features 35 instructions that are optimized for USB applications. In addition, the microcontroller features 128 bytes of internal RAM and either 2 or 4 Kbytes of program memory space. The Cypress USB Controller accepts a 6-MHz ceramic resonator as its clock source. This clock signal is doubled within the chip to provide a 12-MHz clock for the microprocessor.
