Infineon Technologies CY8C24223-24SIT

Overview

CY8C24223-24SIT from Cypress Semiconductor is a programmable mixed-signal System-on-Chip (PSoC) integrating an M8C 8-bit Harvard architecture CPU, 4 KB Flash, 256 bytes SRAM, six configurable analog blocks, and four digital PSoC blocks. It operates at up to 24 MHz with 3.0–5.25 V supply or down to 1.0 V via on-chip switch-mode pump, and supports industrial temperature range (−40°C to +85°C). Used in embedded sensor interface and motor control systems requiring reconfigurable analog/digital peripherals.

For engineers reviewing the CY8C24223-24SIT datasheet, CY8C24223-24SIT pinout, CY8C24223-24SIT application, or CY8C24223-24SIT equivalent, key selection criteria include its 24 MHz M8C core speed, 6-analog/4-digital block architecture, 14-bit ADC capability, 30 mA analog output drive, and ISSP-based in-system programming support.

Technical Context

The CY8C24223-24SIT implements a fully configurable mixed-signal architecture where analog blocks (CT + SC types) and digital blocks are interconnected via global analog/digital buses. Its M8C core executes instructions at up to 24 MHz with 8×8 multiply and 32-bit accumulate, enabling real-time signal processing without external co-processors.

Clocking is flexible: internal ±2.5% 24 MHz IMO, optional 32.768 kHz crystal with PLL for 24 MHz accuracy, and ILO for low-power sleep/wake. Analog system supports up to two 14-bit Delta-Sigma ADCs, two 8-bit DACs, programmable gain amplifiers, and filters-all user-configurable via PSoC Designer software.

FAQ

Does CY8C24223-24SIT support USB communication?

No. The CY8C24223-24SIT does not include a USB physical layer or USB protocol engine. It supports UART, SPI, and I²C interfaces only. For USB connectivity, designers must use external USB-to-UART bridge ICs such as CP2102 or migrate to later PSoC generations like CY8C4xxxx that integrate USB 2.0 FS controllers.

Can the internal 24 MHz oscillator meet timing-critical PWM requirements?

Yes. The internal main oscillator (IMO) is specified at ±2.5% accuracy over voltage and temperature, sufficient for most motor control and lighting PWM applications where absolute frequency precision is less critical than jitter and stability. For tighter tolerance (e.g., audio-class PWM), the optional 32.768 kHz crystal with PLL provides 24 MHz at ±50 ppm accuracy.

Is EEPROM emulation supported, and how durable is it?

Yes. The device supports EEPROM emulation in Flash using Cypress's Emulated EEPROM component in PSoC Designer. Endurance is rated at 100,000 write cycles per emulated byte, with wear-leveling handled automatically by the component firmware - verified per AN2211 and tested across −40°C to +85°C.

What debug interfaces are available during development?

The CY8C24223-24SIT supports full-speed in-circuit emulation via SWD (Serial Wire Debug) using the MiniProg3 or KitProg programmer/debugger. It provides hardware breakpoints, 128 KB trace memory, and real-time variable watch - all accessible through PSoC Designer IDE without requiring JTAG header or external probes.
