Overview
The CY8C26643-24PVIT is an 8-bit microcontroller from the PSoC™ family, featuring a 24 MHz M8C processor. It includes 16 KB of Flash program memory and 256 bytes of SRAM data storage. The device provides 44 I/O pins in a 48-pin SSOP package. Analog capabilities include up to 11-bit Delta-Sigma ADCs, 8-bit Successive Approximation ADCs, and 9-bit DACs. Digital blocks support UART, SPI, and PWM functions.
Feature Summary
- Configurable mixed-signal array with user-definable analog and digital peripheral blocks
- Integrated M8C processor with Harvard architecture and fast multiply/accumulate capability
- Flexible on-chip memory with Flash program storage and EEPROM emulation
- Precision programmable clocking with internal oscillators and external crystal options
Applications
- Consumer electronics requiring mixed-signal processing
- Industrial equipment control systems
- Communications interface modules
- Computation devices needing configurable logic
Procurement Notes
Verify component authenticity through authorized Infineon distributors or certified partners. Confirm datasheet revision *C specifications match design requirements. Check for Not Recommended for New Designs status and evaluate CY8C27xxx alternatives for long-term supply assurance. Ensure proper ESD handling during assembly.
Selection Notes
Select this part when flexible analog-digital integration is required within a single chip. Consider the 48-pin SSOP package constraints and 44 available I/O lines. Evaluate the 16 KB Flash limit against application code size. Verify compatibility with PSoC Designer software tools for configuration.
Part Context
Part of the CY8C26xxx series within the PSoC™ 1 family. Designed as a system-level solution replacing multiple discrete components. Shares core architecture with CY8C25122, CY8C26233, and CY8C26443 variants, differing primarily in pin count and memory allocation.
Replacement Considerations
Officially recommended substitute: CY8C27xxx series. These newer devices offer enhanced features and updated manufacturing processes while maintaining functional compatibility.
