CY7C63723C
Overview
- enCoRe™ USB - enhanced Component Reduction - Internal oscillator eliminates the need for anexternal 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 a nd 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 - Each GPIO pin supports high-impedance inputs, internal pull-ups, open drain outputs or traditional CMOS outputs - Maskable interrupts on all I/O pins
- SPI serial communication block - Master or slave operation - 2 Mbit/s transfers
- Four 8-bit Input Capture registers - Two registers each for two input pins - Capture timer setting with five prescaler settings - Separate registers for ri sing and falling edge capture - Simplifies interface to R
