Overview
The CY8C3244AXA-153 is an obsolete 8-bit microcontroller from Infineon Technologies, part of the PSoC 3 family. It features an 8051 core with a maximum clock frequency of 50 MHz. The device includes 16 kB of Flash program memory and 8 kB of SRAM data RAM. It is housed in a TQFP-100 package and supports a supply voltage range of 1.71 V to 5.5 V. The operating temperature range extends from -40 °C to +85 °C.
Feature Summary
- Integrates an 8051 processor core for standard instruction set compatibility
- Includes programmable analog and digital blocks within the PSoC architecture
- Supports multiple communication interfaces including I2C, SPI, UART, and USB
Applications
- General-purpose embedded control systems
- Industrial automation controllers
- Consumer electronics devices requiring mixed-signal processing
Procurement Notes
This specific part number is officially listed as obsolete and no longer manufactured by Infineon. Procurement should focus on verified distributors offering remaining stock or authorized substitutes. Verify component authenticity through official channels due to end-of-life status. Ensure compatibility with existing PCB footprints and firmware before acquisition.
Selection Notes
Engineers replacing this component should consider the CY8C3244AXI-153 as a parametric equivalent available in the same family. Both share the 8051 core, 50 MHz speed, and similar memory configurations. Selection must account for package differences and current availability. Review datasheets for any minor interface variations between the A and I suffixes to ensure seamless integration into existing designs.
Part Context
The CY8C3244AXA-153 belongs to the PSoC 3 series, which combines a programmable system-on-chip with an 8051 CPU. This series allows designers to customize analog and digital peripherals. The AXA suffix typically denotes automotive-grade qualification, although specific AEC-Q100 confirmation requires direct datasheet verification. The model represents a legacy solution for mixed-signal applications.
Replacement Considerations
The CY8C3244AXI-153 is confirmed as a publicly listed substitute for the obsolete CY8C3244AXA-153. Both units share identical core specifications and memory sizes. Designers must verify package pinout compatibility and confirm that the replacement meets all environmental and electrical requirements of the original design.
