Overview
The CY8C21323-24LQXIT is an 8-bit microcontroller from the PSoC family, featuring an M8C processor core with speeds up to 24 MHz. It includes 4 KB of Flash program storage and 256 bytes of SRAM data storage. The device operates within a voltage range of 2.4 V to 5.25 V, or down to 1.0 V using the on-chip switch mode pump. It supports industrial temperature ranges from –40 °C to +85 °C and offers configurable analog and digital peripherals via PSoC blocks.
Feature Summary
- Configurable analog and digital system-on-chip architecture allowing custom peripheral creation
- On-chip switch mode pump enabling operation from a single battery cell
- Flexible memory with in-system serial programming and partial flash updates
- Programmable GPIO with multiple drive modes and interrupt capabilities
Applications
- Battery-powered devices requiring low-voltage operation
- Systems needing customizable analog signal processing
- Applications requiring flexible digital communication interfaces
- Cost-sensitive embedded control systems
Procurement Notes
Verify the specific ordering suffix matches the required package type and temperature grade. Confirm that the component meets RoHS compliance standards for your region. Ensure development tools like PSoC Designer are compatible with this device series before procurement.
Selection Notes
Select this model when a balance of programmability and cost is required. Consider the limited SRAM size for complex applications. Evaluate if the available I/O count and peripheral blocks meet the system requirements without needing additional external components.
Part Context
This part belongs to the CY8C21x23 series of PSoC devices. It shares architectural similarities with other members of the family but differs in memory size and pin count. It is designed to replace multiple traditional MCU-based components with a single programmable chip.
Replacement Considerations
Check for direct substitutes within the CY8C21x23 family. Verify pin compatibility and memory specifications when considering alternative packages or variants.
