Overview
The CY8C24423A5-24PXI is an 8-bit microcontroller IC from the Cypress PSoC1 family, featuring the M8C core operating at a maximum frequency of 24 MHz. It integrates 4 KB of FLASH memory and 256 bytes of SRAM. The device includes mixed-signal capabilities with two 14-bit analog-to-digital converters and two 9-bit digital-to-analog converters. It supports I²C, SPI, and UART/USART communication interfaces. The component is housed in a 28-pin DIP package and operates within a voltage range of 2.4 V to 5.25 V across temperatures from -40 °C to +85 °C.
Feature Summary
- Integrates mixed-signal array technology combining digital processing with analog conversion capabilities
- Supports multiple serial communication protocols including I²C, SPI, and UART for versatile connectivity
- Features embedded flash memory for non-volatile code storage and data retention
Applications
- Automotive systems requiring robust microcontroller performance
- Capacitive sensing applications utilizing integrated analog peripherals
- Embedded controller designs for consumer electronics
- USB-enabled peripheral devices leveraging PSoC architecture
Procurement Notes
Verify the specific suffix '5' against official Cypress documentation to confirm exact electrical characteristics and package variations. Ensure compatibility with existing PCB footprints for the 28-DIP configuration. Cross-reference the manufacturing date code and RoHS status with current supplier declarations to meet regulatory requirements. Confirm that the 24 MHz clock speed meets system timing constraints before finalizing procurement orders.
Selection Notes
Select this component when an 8-bit architecture suffices for control tasks while requiring integrated ADC and DAC functions. The PSoC1 platform allows reconfigurable analog blocks, reducing external component count. Consider the 28-pin DIP package for prototyping or through-hole assembly needs. Evaluate the 4 KB FLASH limit against application firmware size requirements prior to selection.
Part Context
This part belongs to the Cypress PSoC1 series, which merges an 8-bit M8C processor with programmable analog and digital blocks. The CY8C24xxx variant specifically targets cost-sensitive applications needing mixed-signal integration. The device represents a transition point in Cypress's portfolio between standard 8-bit MCUs and more complex PSoC3/5 architectures.
Replacement Considerations
Direct substitutes include other CY8C24423A variants with different package codes such as CY8C24423A-24LTXI for QFN packaging. Verify pinout compatibility when replacing DIP packages with surface-mount alternatives. Check if updated suffixes indicate minor electrical improvements without altering functional behavior.
