Product details

Overview

CY7C63823-XC from Cypress Semiconductor is an 8-bit flash-based low-speed USB/PS/2 peripheral controller with Harvard architecture M8C CPU, 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 control endpoint and two data endpoints, conforms to USB 2.0 and HID 1.1, and targets HID peripherals such as optical mice and gamepads.

For engineers reviewing the CY7C63823-XC datasheet, CY7C63823-XC pinout, CY7C63823-XC application, or CY7C63823-XC equivalent, key selection considerations include its dual-mode USB/PS/2 auto-configuration without GPIO mode-switching, internal D– pull-up resistor, 10 µA suspend current, 256-byte RAM, and 8 KB flash with EEROM emulation - all in a 24-pin SOIC package.

Technical Context

The CY7C63823-XC implements a dedicated low-speed USB Serial Interface Engine (SIE) compliant with USB 2.0 at 1.5 Mbps, supporting only one device address and endpoint 0 (control) plus endpoints 1 and 2 (data). Its USB PHY includes a dedicated 3.3 V regulator and integrated D– pull-up, eliminating external bias components.

It features a crystalless internal oscillator tunable to ±1.5% over temperature and voltage, optionally lockable to external 12/24 MHz clocks for tighter timing. The M8C core runs up to 24 MHz, supports maskable interrupts on all I/O pins, and integrates a 12-bit programmable interval timer and dual-channel 8-bit capture timers for RF edge timing - critical for wireless remote and optical sensor interfaces.

Key Specifications

Parameter	Value and Actual Design Meaning
USB Speed	Low-speed only (1.5 Mbps); no full-speed capability - limits use to HID, not mass storage or high-bandwidth devices.
CPU Core	M8C 8-bit Harvard architecture; executes instructions at up to 24 MHz - optimized for USB descriptor handling and HID report processing.
Memory	8 KB flash (with EEROM emulation) + 256 bytes RAM - sufficient for compact HID firmware and runtime variable storage.
Regulators	Dedicated 3.3 V USB PHY regulator + 125 mA main 3.3 V regulator - powers external sensors or LEDs without secondary LDOs.
GPIO	Up to 20 pins; 4 × 3.3 V-tolerant I/O; configurable 8/50 mA sink per designated pin - enables direct LED driving or switch debouncing.
Timing	Crystalless 24 MHz oscillator (±1.5%) + optional external 12/24 MHz clock input - eliminates BOM cost of crystal/resonator and associated load caps.
Power	10 µA sleep current, 10 mA typical @ 6 MHz - suitable for battery-powered remotes and dongles requiring long standby life.

Pinout & Package

Package: 24-pin SOIC (Small Outline Integrated Circuit), 300 mil width, surface-mount compatible. Thermal pad not present; standard JEDEC MS-013AC footprint.

Pin/Terminal	Circuit Role	Design Meaning
VDD	Main power supply	4.0–5.5 V DC input; powers core logic and GPIO ports.
VSS	Ground reference	Digital ground return for all internal circuits and I/O drivers.
USB_D+	USB differential data+	Low-speed USB bidirectional signal; internally pulled to 3.3 V via 1.5 kΩ resistor when enabled.
USB_D−	USB differential data−	Low-speed USB bidirectional signal; includes internal D− pull-up for device enumeration.
XIN/XOUT	External clock interface	Optional 12/24 MHz crystal or CMOS clock input; bypassed when using internal oscillator.
P0.0–P0.7	Port 0 general-purpose I/O	Individually configurable; P0.2–P0.4 support dedicated interrupt vectors for wake-up events.
P1.0–P1.3	3.3 V I/O port	Fixed 3.3 V logic level; supports SPI master/slave, open-drain, or CMOS output - ideal for interfacing with 3.3 V sensors.
RESET	Active-low reset input	Asynchronous reset; internal POR circuit ensures reliable startup without external RC network.

Key Features

Feature	Design Value
USB/PS/2 auto-configuration	No GPIO pins required to select interface mode - hardware detects host protocol and configures transceiver automatically.
Integrated USB pull-up	Internal 1.5 kΩ D− pull-up resistor eliminates discrete component and PCB routing for USB enumeration.
Crystalless operation	On-chip oscillator meets USB low-speed timing tolerance (±1.5%) without external crystal - reduces BOM count by ≥2 parts.
Capture timer subsystem	Two independent 8-bit registers per input pin store rising/falling edge timestamps - enables precise RF carrier decoding in wireless remotes.
Configurable drive strength	Selectable 8 mA or 50 mA sink current on designated pins - drives LEDs directly without external transistor or current-limiting resistors.

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
CY7C63822-XC	Same enCoRe II core, but 16-pin SOIC; only 14 GPIO pins and no 3.3 V I/O pins.	Limited I/O count and absence of 3.3 V logic restricts use with modern 3.3 V sensors or SPI peripherals.	Select when board space is constrained and interface requirements are minimal (e.g., simple button-only HID).
CY7C63824-XC	Identical feature set and pinout, but rated for industrial temperature range (–40 °C to +85 °C) vs. CY7C63823-XC's 0 °C to +70 °C.	Required for automotive cabin accessories or industrial POS terminals operating outside commercial temperature limits.	Choose for extended thermal environments where reliability under thermal stress is mandatory.

Compared with CY7C63822-XC, the CY7C63823-XC provides 3.3 V I/O and additional GPIO for richer peripheral integration; versus CY7C63824-XC, it offers cost-optimized commercial-grade operation without industrial temp qualification overhead.

FAQ

Is CY7C63823-XC USB-IF certified?

Yes, CY7C63823-XC is USB-IF certified under TID #40000085 for USB 2.0 low-speed compliance. Certification covers electrical signaling, enumeration behavior, and HID descriptor handling - enabling plug-and-play compatibility with Windows, macOS, and Linux without custom drivers.

Does CY7C63823-XC support full-speed USB?

No, CY7C63823-XC supports low-speed USB only (1.5 Mbps). It lacks the transceiver circuitry, PLL bandwidth, and timing precision required for full-speed (12 Mbps) operation. Designs requiring higher bandwidth must use a different controller family such as CY7C68013A.

Can CY7C63823-XC operate without an external crystal?

Yes - it features a factory-trimmed internal 24 MHz oscillator meeting USB low-speed timing tolerance (±1.5%). External crystal is optional and used only when tighter frequency stability is required, such as in multi-device synchronization scenarios.

What development tools support CY7C63823-XC firmware programming?

Cypress PSoC Designer IDE (legacy) fully supports CY7C63823-XC, including drag-and-drop USB HID user modules, C compiler, in-circuit emulation, and bootloader configuration. The CY3655 enCoRe II Development Kit provides hardware debugging and reference firmware examples for mouse, keyboard, and gamepad implementations.
