Infineon Technologies CY7C60223-SXC

Overview

CY7C60223-SXC from Infineon Technologies (formerly Cypress) is an 8-bit Harvard-architecture M8C microcontroller with 8 KB flash, 256 bytes RAM, and up to 36 GPIO pins. It operates from 2.7 V to 3.6 V, supports crystalless operation via internal oscillator, and integrates dual 8-bit capture timers for RF input timing-used in optical mice and wireless remote controls.

For engineers reviewing the CY7C60223-SXC datasheet, CY7C60223-SXC pinout, CY7C60223-SXC application, or CY7C60223-SXC equivalent, key selection criteria include low-voltage operation (2.7–3.6 V), configurable 50 mA sink per designated I/O pin, 12 MHz CPU speed, in-system reprogrammability via P1.0/P1.1, and integrated wakeup timer for battery-powered HID devices.

Technical Context

The CY7C60223-SXC implements a dedicated M8C CPU core with Harvard memory architecture, supporting up to 12 MHz operation from internal oscillator, external crystal (1–24 MHz), or external clock source. Its clock control includes trimmable internal oscillator and CLKIN/CLKOUT pins for precision timing synchronization.

It features two independent 8-bit capture timer registers tied to P0.5 (TIO0) and P0.6 (TIO1), each storing rising/falling edge timestamps from the 16-bit free-running timer-enabling precise RF pulse width measurement without firmware overhead. The vectored interrupt controller supports 17 maskable sources, including GPIO edge interrupts on all pins and programmable interval timer events.

FAQ

Does CY7C60223-SXC support USB connectivity?

No. The CY7C60223-SXC is a non-USB variant of the enCoRe II family. It lacks USB transceivers and associated PHY layers. It is intended for SPI-, GPIO-, or proprietary RF-based communication. USB-capable derivatives like CY7C601xx include dedicated USB modules and require different pinouts and firmware stacks.

What is the maximum sink current per GPIO pin on CY7C60223-SXC?

Designated pins (P0.0–P0.4, P1.0–P1.7, P2.0–P2.7, P3.0–P3.7, P4.0–P4.3) support configurable 8 mA or 50 mA sink current. This is set per port group via configuration registers-not per individual pin-and applies only to ports 2–4 and selected bits of ports 0–1. Default is 8 mA unless explicitly programmed to 50 mA.

Can the internal oscillator be trimmed for improved accuracy?

Yes. The internal oscillator frequency is adjustable via the IOSCTR register using factory-trimmed values stored in SROM. Trim range is ±10% around nominal 12 MHz, enabling calibration to match system timing requirements without external crystal-critical for RF carrier alignment in wireless remotes.

Is CY7C60223-SXC pin-compatible with other enCoRe II LV devices?

Pin compatibility is package-dependent and function-specific. The CY7C60223-SXC in 24-pin SOIC shares identical pinout with CY7C60223 in QSOP, but differs from 40-pin PDIP and 48-pin SSOP variants. Function mapping (e.g., TIO0/TIO1 location) is consistent across packages, though unused pins (NC) and port allocations vary by pin count.
