Product details
Overview
CY7C63310-SXC from Cypress Semiconductor is an 8-bit flash-based low-speed USB/PS/2 peripheral controller with Harvard architecture M8C core, integrated USB transceiver, crystalless 24 MHz oscillator (±1.5%), dual 3.3 V regulators (125 mA main + dedicated USB PHY), and up to 20 GPIO pins. It supports one USB device address, control + two data endpoints, HID v1.1 compliance, and in-system reprogrammability - deployed in optical mice and gaming controllers.
For engineers reviewing the CY7C63310-SXC datasheet, CY7C63310-SXC pinout, CY7C63310-SXC application, or CY7C63310-SXC equivalent, key selection criteria include USB/PS/2 dual-mode auto-configuration without GPIO mode-switching, 3.3 V I/O compatibility, capture timer support for RF edge timing, low-power suspend wakeup (10 µA), and EEROM-emulated flash storage.
Technical Context
The CY7C63310-SXC integrates a USB Serial Interface Engine (SIE) compliant with USB 2.0 low-speed (1.5 Mbps) and HID 1.1, with internal D– pull-up and dedicated 3.3 V regulator for signal integrity. Its clock system supports internal 24 MHz oscillator tuning or external 12/24 MHz reference for precise USB timing alignment.
It features a programmable 12-bit interval timer, 16-bit free-running timer with dual-edge capture registers per input pin, and vectored interrupt controller supporting 22 maskable sources - including GPIO interrupts on all pins and dedicated vectors for P0.2–P0.4. Power management includes POR, configurable low-voltage detect, and watchdog timer.

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-speed USB peripheral controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C63742-SXCT | Same enCoRe II family; adds integrated 12-bit ADC (8 channels) and enhanced GPIO drive (50 mA sink on all pins). | Better suited for analog sensor interfaces (e.g., pressure-sensing game pads); higher pin count (24-pin QFN). | Select when analog sensing or higher drive strength is required; not drop-in due to package and ADC resource differences. |
| STM32F042F4P6 | ARM Cortex-M0 core; full-speed USB (12 Mbps); no native PS/2 support; requires external crystal for USB timing. | Targets more complex HID devices needing higher throughput or mixed-signal integration; lacks crystalless USB and PS/2 auto-detect. | Choose for future-proofing with full-speed USB or ARM ecosystem compatibility; adds BOM complexity and firmware overhead. |
Compared with CY7C63742-SXCT, the CY7C63310-SXC offers lower system cost and simpler layout via crystalless operation and smaller SOIC package, while STM32F042F4P6 provides greater processing headroom and USB bandwidth at the expense of external timing components and PS/2 capability.

FAQ
Does CY7C63310-SXC require an external crystal for USB operation?
No. The device features a crystalless 24 MHz internal oscillator tuned to ±1.5% accuracy for USB low-speed compliance. An external 12 MHz or 24 MHz clock may be used for tighter timing control, but is optional - eliminating BOM cost and board space for crystals or resonators in most HID designs.
Can CY7C63310-SXC operate in both USB and PS/2 modes simultaneously?
No. It supports automatic USB or PS/2 mode selection at enumeration time, but only one interface is active per session. Mode switching requires bus reset and re-enumeration - not real-time toggling. The dual-mode capability enables single-hardware designs compatible with legacy PS/2 systems and modern USB hosts.
What is the maximum sink current capability of its GPIO pins?
Standard GPIO pins provide 2 mA source and 8 mA sink. Pins designated for higher drive (P0.0–P0.3, P1.0–P1.3) support configurable 50 mA sink current - verified in DC characteristics tables (Rev. *T, page 74). This enables direct LED driving or relay control without external drivers in low-power peripherals.
Is in-system programming supported over USB without additional hardware?
Yes. The device includes a built-in USB bootloader that accepts firmware updates via standard USB HID class requests. No external programmer is needed - only a USB cable and Cypress-provided tools (e.g., PSoC Designer) or custom host software implementing the bootloader protocol.
