CY7C63101A-QC

通用串行总线的微控制器 Universal Serial Bus Microcontroller

Functional Overview

The CY7C630/101A 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 four 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.
