EZ-USB FX1™ USB Microcontroller Full-speed USB Peripheral Controller CY7C64713/14 is a USB microcontroller released by Cypress Semiconductor Corporation. It features a single-chip integrated USB transceiver, SIE, and enhanced 8051 microprocessor. It is pin-compatible, object-code-compatible and functionally-compatible with FX2LP (CY7C68013A). It draws no more than 65 mA in any mode, making it suitable for bus powered applications.
The EZ‑USB FX1™ (CY7C64713/14) is a full‑speed, highly integrated USB microcontroller that combines a USB transceiver, Smart SIE, an enhanced 8051 core, and a programmable peripheral interface in a single chip. It is designed for bus‑powered applications, drawing no more than 65 mA, and supports 3.3 V operation with 5 V‑tolerant inputs.
Key features include up to a 48 MHz clock rate, two USARTs, three timer/counters, an I²C controller (100 kHz or 400 kHz), four programmable endpoints, and three lead‑free package options (56‑pin QFN, 100‑pin TQFP, 128‑pin TQFP). The device provides extensive interrupt and autovector capabilities, as well as flexible memory configurations with 16 KB of internal RAM.
