Infineon Technologies CY8C24223A-24PVXI

Overview

CY8C24223A-24PVXI from Cypress Semiconductor is a programmable 8-bit Harvard-architecture PSoC® SoC featuring an M8C CPU core running up to 24 MHz, 4 KB flash, 256 bytes SRAM, and integrated analog/digital blocks including six analog and four digital PSoC blocks. It operates from 2.4 V to 5.25 V (or down to 1.0 V with on-chip switch-mode pump), supports industrial temperature range (–40 °C to +85 °C), and targets embedded control with mixed-signal integration.

For engineers reviewing the CY8C24223A-24PVXI datasheet, CY8C24223A-24PVXI pinout, CY8C24223A-24PVXI application, or CY8C24223A-24PVXI equivalent, key selection criteria include its 28-pin PDIP package, 24 MHz IMO clock accuracy (±5%), I²C/SPI/UART peripheral support, configurable GPIO drive modes (25 mA sink), and analog subsystem capability (14-bit ADC, PGA, filters).

Technical Context

The device implements a fixed-function M8C 8-bit CPU core with Harvard architecture, supporting 8×8 multiply and 32-bit accumulate operations. Its digital system comprises four 8-bit digital PSoC blocks that can be combined into 8–32-bit timers, PWMs, UART, SPI, I²C (slave/multi-master), CRC, and PRS modules - all routable to any GPIO via global digital interconnect.

The analog system integrates six rail-to-rail analog PSoC blocks enabling configurable ADCs (up to 14-bit), DACs (up to 9-bit), PGAs, comparators, and programmable filters. Clocking includes a ±5% 24 MHz internal main oscillator (IMO), optional 32.768 kHz crystal with PLL for 24 MHz precision, and low-power 32 kHz ILO for sleep/WDT.

FAQ

What development tools are required to program the CY8C24223A-24PVXI?

PSoC Designer™ (free Windows IDE) is the official development environment, providing drag-and-drop hardware configuration, C firmware coding, and ISSP programming support. Required hardware includes CY3210-24x23 EvalPod for evaluation or CY8CKIT-002 MiniProg3 for production programming. No third-party toolchain is needed.

Does the CY8C24223A-24PVXI support true hardware I²C master mode?

Yes - it implements full I²C slave, master, and multi-master functionality up to 400 kHz, with dedicated hardware resources in the digital PSoC blocks. The I²C module supports standard addressing, repeated start, and clock stretching, and is independently routable to any GPIO pin via global interconnect.

Can the analog blocks perform simultaneous ADC and DAC operations?

Yes - the six analog PSoC blocks operate independently and concurrently. For example, one block can run a 14-bit successive-approximation ADC while another drives a 9-bit DAC output, with both sharing the same reference and synchronized via CPU-triggered or timer-driven events.

Is the 24 MHz internal oscillator accurate enough for UART communication?

At ±5% tolerance over temperature and voltage, the 24 MHz IMO meets UART requirements for 9600 bps and 19200 bps with standard 16× oversampling. For higher baud rates (e.g., 115200 bps), use the 32.768 kHz crystal with PLL to generate a crystal-locked 24 MHz clock, achieving <±0.5% error.
