CY7C63723-SXC
enCoRe™ USB Combination Low-Speed USB and PS/2 Peripheral Controller
Features
enCoRe™ USB - enhanced Component Reduction
Internal oscillator eliminates the need for an external
crystal or resonator
Interface can auto-configure to operate as PS/2 or
USB without the need for external components to
switch between modes (no General Purpose I/O
[GPIO] pins needed to manage dual mode capability)
Internal 3.3V regulator for USB pull-up resistor
Configurable GPIO for real-world interface without
external components
Flexible, cost-effective solution for applications that
combine PS/2 and low-speed USB, such as mice, gamepads, joysticks, and many others.
USB Specification Compliance
Conforms to USB Specification, Version 2.0
Conforms to USB HID Specification, Version 1.1
Supports one low-speed USB device address and
three data endpoints
Integrated USB transceiver
3.3V regulated output for USB pull-up resistor
8-bit RISC microcontroller
Harvard architecture
6-MHz external ceramic resonator or internal clock
mode
12-MHz internal CPU clock
Internal memory
256 bytes of RAM
8 Kbytes of EPROM
Interface can auto-configure to operate as PS/2 or
USB
No external components for switching between PS/2
and USB modes
No GPIO pins needed to manage dual mode
capability
I/O ports
Up to 16 versatile GPIO pins, individually
configurable
High current drive on any GPIO pin: 50 mA/pin
current sink
