Product details

Overview

CY7C63823-PXC from Cypress Semiconductor is an 8-bit flash-programmable enCoRe™ II low-speed USB peripheral controller with integrated USB transceiver, crystalless 24 MHz oscillator, dual 3.3 V regulators (125 mA main + dedicated USB PHY), and up to 20 GPIO pins. It supports USB 2.0 (TID #40000085) and PS/2 dual-mode operation without external mode-switching components, and delivers 10 µA sleep current for HID peripherals like optical mice and gamepads.

For engineers reviewing the CY7C63823-PXC datasheet, CY7C63823-PXC pinout, CY7C63823-PXC application, or CY7C63823-PXC equivalent, key selection criteria include its USB/PS2 auto-configuration capability, internal 24 MHz ±1.5% oscillator tuning, 8 KB flash with EEROM emulation, 256-byte RAM, and 3.3 V I/O compatibility - all in a 24-pin SOIC package.

Technical Context

The CY7C63823-PXC implements a Harvard-architecture M8C CPU running at up to 24 MHz, with USB Serial Interface Engine (SIE) handling endpoint 0 (control), endpoint 1 (IN), and endpoint 2 (OUT) per USB 2.0 low-speed spec. Its clock architecture supports internal oscillator lock to USB traffic timing or external 12/24 MHz reference for tighter tolerance.

It integrates a dedicated 3.3 V regulator for USB D– pull-up and signal integrity, plus a separate 125 mA 3.3 V regulator for external peripherals. The device features two capture timer channels (rising/falling edge timestamps per pin), 12-bit programmable interval timer, and maskable GPIO interrupts on all 20 I/O pins - enabling precise RF input decoding and low-power wake-on-event operation.

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
CY7C63823-PC	Same die, PDIP-24 package; no thermal pad; higher thermal resistance (θ_JA = 70°C/W vs. SOIC's 55°C/W)	Suitable for through-hole prototyping or legacy board designs; not recommended for high-density SMT production	Select only if manual assembly or socket-based testing is required; SOIC offers better manufacturability and thermal performance.
CY7C63823-PXI	Identical functionality and pinout; extended temperature range (–40°C to +85°C) vs. commercial (0°C to +70°C)	Required for industrial or automotive-adjacent environments where ambient exceeds 70°C	Choose for deployments outside office/indoor consumer settings; otherwise, CY7C63823-PXC provides full feature set at lower cost.

Compared with CY7C63823-PC and CY7C63823-PXI, the CY7C63823-PXC balances commercial-grade reliability, SOIC manufacturability, and optimal thermal performance - making it the default choice for volume HID peripheral production where ambient temperature stays within 0–70°C.

FAQ

Does CY7C63823-PXC require an external crystal to operate in USB mode?

No. The device features a crystalless internal 24 MHz oscillator that auto-tunes to USB traffic timing requirements (±1.5%). An external 12 MHz or 24 MHz clock may be used for tighter tolerance, but is optional - eliminating BOM cost and PCB footprint associated with crystals or resonators.

Can CY7C63823-PXC operate as both USB and PS/2 device simultaneously?

No. It supports automatic USB or PS/2 mode selection at power-up based on host handshake, but operates in only one protocol at a time. The dual-mode capability means no external GPIOs or logic are needed to configure the interface - mode switching is handled entirely in firmware and transceiver logic.

What is the maximum sink current capability of GPIO pins on CY7C63823-PXC?

Standard GPIO pins provide 2 mA source and 8 mA sink. Pins P0.0–P0.3 and P1.0–P1.3 support configurable 50 mA sink current when enabled via register settings - enabling direct drive of small solenoids, LEDs, or buzzer circuits without external drivers.

Is in-system programming supported for CY7C63823-PXC after soldering to the PCB?

Yes. The device supports full in-system reprogrammability via its USB interface using Cypress-provided bootloader firmware. No external programmer or debug header is required - firmware updates can be delivered over USB using standard HID class commands or custom vendor requests.
