CY8C26233-24SXI

Overview

The CY8C26233-24SXI is an 8-bit Programmable System-on-Chip (PSoC) microcontroller from Infineon Technologies, housed in a 20-SOIC package. It features the M8C processor core operating at speeds up to 24 MHz. The device includes 8 KB of Flash program memory and 256 bytes of SRAM data storage. Connectivity options include SPI and UART/USART interfaces. Integrated peripherals support Low Voltage Detection (LVD), Power-On Reset (POR), Pulse Width Modulation (PWM), and Watchdog Timer (WDT) functions.

Feature Summary

• Configurable mixed-signal array with user-programmable analog and digital peripheral blocks
• Integrated M8C Harvard architecture processor with fast multiply/accumulate capabilities
• Flexible on-chip memory with Flash program storage and EEPROM emulation support
• Precision programmable clocking with internal oscillators and external crystal options

Applications

• Programmable system-level solutions replacing multiple MCU-based components
• Consumer electronics requiring configurable analog and digital I/O
• Industrial equipment utilizing programmable filters and comparators
• Communications devices employing SPI or UART protocols

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific ordering suffix matches the required package type and temperature range. Check for current lifecycle status as this family may be superseded by newer series. Ensure compliance with RoHS directives relevant to your region before procurement.

Selection Notes

Select this component when design flexibility requires reconfigurable analog and digital blocks within a single chip. Consider the 24 MHz processing speed and 8 KB memory capacity against application requirements. Evaluate the 20-pin SOIC footprint for board space constraints. Verify compatibility with PSoC Designer software tools for configuration.

Part Context

This part belongs to the CY8C26xxx family of PSoC 1 devices, which integrate an 8-bit CPU with programmable analog and digital blocks. The family allows designers to customize peripheral configurations via software rather than fixed hardware logic. This approach reduces bill-of-materials count and accelerates development cycles compared to traditional discrete MCU designs.

Replacement Considerations

Official documentation indicates the CY8C27xxx series as the recommended replacement for new designs. Verify pinout compatibility and memory size differences between the legacy CY8C26233 and the successor CY8C27xxx parts before substitution.
