Infineon Technologies CY7C60223-PXC

Overview

CY7C60223-PXC from Cypress Semiconductor is an enCoRe™ II Low Voltage 8-bit Flash microcontroller with Harvard architecture, operating at up to 12 MHz, 8 KB Flash (with EEROM emulation), 256 bytes RAM, and 36 GPIO pins. It integrates a crystalless internal oscillator, dual 8-bit capture timers for RF edge timing, programmable low-voltage detection, and SPI interface - designed for cost-sensitive wireless HID devices such as optical mice and presenter tools.

For engineers reviewing the CY7C60223-PXC datasheet, CY7C60223-PXC pinout, CY7C60223-PXC application, or CY7C60223-PXC equivalent, key selection criteria include its 24-pin QSOP package, 2.7–3.6 V operation, 5 µA sleep current, configurable 8/50 mA sink per pin, and dedicated TIO0/TIO1 capture inputs for RF demodulation and pulse timing in battery-powered peripherals.

Technical Context

The CY7C60223-PXC implements a Harvard-architecture M8C CPU with on-chip 8 KB Flash and 256-byte RAM, supporting in-system reprogramming via P1.0/P1.1 serial programming interface. Its internal 12 MHz oscillator eliminates external crystals, while optional CLKIN/CLKOUT pins allow precision clock sourcing up to 24 MHz.

It features two independent 8-bit capture timer registers (TCAP0R/TCAP1R and TCAP0F/TCAP1F) tied to P0.5/TIO0 and P0.6/TIO1, capturing both rising and falling edge timestamps from the 16-bit free-running timer - enabling precise RF carrier demodulation and pulse-width measurement without external logic.

Key Specifications

Pinout & Package

FAQ

Does CY7C60223-PXC support USB natively?

No. The CY7C60223-PXC is a standalone 8-bit microcontroller without integrated USB PHY or USB firmware stack. It is designed for non-USB applications such as RF HID peripherals that pair with USB bridge ICs (e.g., CY7C63723) or proprietary 2.4 GHz transceivers. USB functionality must be implemented externally.

What is the maximum frequency supported on P0.5/TIO0 and P0.6/TIO1 for edge capture?

The capture logic samples P0.5 and P0.6 synchronously to the internal 12 MHz clock or external clock source. Edge detection is guaranteed for input frequencies up to 6 MHz (half the system clock), with timestamp resolution of 83.3 ns at 12 MHz - sufficient for 27 MHz and 96 MHz RF carrier envelope timing.

Can the internal oscillator be calibrated for improved accuracy?

Yes. The CY7C60223-PXC includes factory-trimmed oscillator calibration values stored in IOSCTR (address 0x34) and supports user fine-tuning via the FREQTRIM bits in LPOSCTR (0x36). Typical accuracy after calibration is ±1.5% over 0–70°C, adequate for non-critical timing in HID applications.

Is there hardware support for I²C communication?

No. The CY7C60223-PXC does not include a dedicated I²C peripheral. Communication is limited to SPI (master/slave, full/half-duplex) and bit-banged UART or I²C via GPIO - though the latter sacrifices timing precision and increases firmware overhead. External I²C sensors require software-driven bit-banging or companion level-shifting bridge ICs.
