Overview
The CY8C27443-24PVXIT is an 8-bit microcontroller from the Infineon PSoC1 family, utilizing the M8C core. It features 16 kB of Flash program memory and 256 bytes of SRAM data RAM. The device operates at a maximum clock frequency of 24 MHz within a supply voltage range of 3 V to 5.25 V. It includes a 14-bit ADC with 12 channels, two timers/counters, and supports GPIO, I2C, SPI, and UART interfaces. Packaged in a 28-pin SSOP, it functions within an industrial temperature range of -40°C to +85°C.
Feature Summary
- Integrates configurable analog and digital peripherals on a single chip for system-level flexibility.
- Includes a 14-bit Analog-to-Digital Converter with multiple input channels for precise signal acquisition.
- Supports standard communication protocols including I2C, SPI, and UART for versatile connectivity.
Applications
- Consumer electronics requiring mixed-signal processing
- Industrial equipment control systems
- Automotive instrumentation modules
Procurement Notes
Verify the suffix 'T' indicates tape-and-reel packaging versus the tube packaging of the base part number. Confirm RoHS compliance status through official documentation. Ensure moisture sensitivity level requirements are met during storage and handling. Validate that the specific revision matches design-in specifications.
Selection Notes
Choose this variant when reel packaging is required for automated assembly processes. Compare against the tube-packaged CY8C27443-24PVXI if volume handling differs. Ensure the 28-pin SSOP footprint fits the target PCB layout. Verify that the 16 kB Flash capacity meets application code size requirements.
Part Context
This component belongs to the Cypress/Infineon PSoC1 series, which combines an 8-bit MCU with programmable analog blocks. The CY8C27443 model specifically targets applications needing mixed-signal capabilities without external components. The PSoC architecture allows customization of peripheral functions via hardware configuration tools.
Replacement Considerations
Direct substitutes include CY8C27443-24PVXI, differing primarily in packaging format (tube vs. tape-and-reel). Other members of the CY8C27x43 family may offer pin-compatible alternatives with varying memory sizes or peripheral configurations.
