Infineon Technologies CY8C24223A-24PVXIT

Overview

CY8C24223A-24PVXIT from Cypress Semiconductor is a programmable 8-bit PSoC® System-on-Chip featuring an M8C CPU core, 4 KB flash, 256 bytes SRAM, and configurable analog/digital blocks. It operates from 2.4 V to 5.25 V (down to 1.0 V with SMP), supports up to 24 MHz clocking, and delivers rail-to-rail analog functions including 14-bit ADCs, 9-bit DACs, PGAs, and filters - deployed in industrial sensor interface and embedded control applications.

For engineers reviewing the CY8C24223A-24PVXIT datasheet, CY8C24223A-24PVXIT pinout, CY8C24223A-24PVXIT application, or CY8C24223A-24PVXIT equivalent, key selection criteria include its 28-pin SSOP package, dual I²C (slave/master/multi-master), 24 MHz IMO ±5%, on-chip voltage reference, and GPIO-configurable analog inputs/outputs with 25 mA sink capability.

Technical Context

The device implements a Harvard-architecture M8C core executing at up to 24 MHz with 8×8 multiply and 32-bit accumulate support. Its digital system integrates four 8-bit PSoC blocks enabling flexible user modules: 8–32-bit timers/counters, 8/16-bit PWMs with dead-band, UART, SPI, and CRC/PRS generators.

The analog system comprises six rail-to-rail configurable blocks supporting ADCs (up to 14-bit), DACs (up to 9-bit), programmable gain amplifiers, comparators, and filters. All analog resources route through eight standard GPIO analog inputs and two 30 mA analog outputs, with internal precision voltage reference and LVD supervision.

FAQ

Does CY8C24223A-24PVXIT support in-circuit debugging?

Yes. It supports full-speed in-circuit emulation and debugging via the two-pin SWD interface using Cypress MiniProg3 or third-party tools compliant with PSoC Designer. Breakpoint structure includes complex conditional triggers and 128 KB trace memory for real-time firmware analysis without halting execution.

What is the maximum ADC resolution achievable on this device?

The device achieves up to 14-bit effective resolution using its decimator-based SAR ADC architecture with programmable oversampling and digital filtering. Actual ENOB depends on input signal frequency and configuration but reaches ≥12.5 bits at 100 SPS with internal reference and proper layout.

Can all GPIO pins be used for analog input simultaneously?

No. While eight GPIO pins support standard analog input routing, only four additional analog inputs are available with restricted routing paths - limiting total concurrent analog inputs to eight. Port 2 pins P2[0]–P2[4] support analog output but not analog input.

Is the internal 24 MHz oscillator calibrated at production?

Yes. The internal main oscillator (IMO) is factory-trimmed to ±5% accuracy across –40 °C to +85 °C and 2.4–5.25 V. At 0–70 °C, typical accuracy improves to ±2.5%. Calibration data is stored in device ROM and applied automatically on power-up.
