CY8C21312-24PVXA

Overview

The CY8C21312-24PVXA is an 8-bit microcontroller from the PSoC 1 family, utilizing the M8C core. It features 8 KB of Flash program memory and 512 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 provides 16 I/O pins and supports I2C, SPI, and UART interfaces. Packaged in a 20-SSOP format, it functions between -40°C and +85°C.

Feature Summary

• Integrates programmable analog blocks for mixed-signal applications
• Includes CapSense technology for capacitive touch sensing
• Features on-chip Flash memory for non-volatile code storage
• Supports standard serial communication protocols

Applications

• Capacitive touch interface controllers
• General-purpose embedded control systems
• Battery-powered devices requiring low power operation
• Industrial monitoring and sensor nodes

Procurement Notes

Verify the specific suffix PVXA confirms the SSOP-20 package and commercial temperature range. Confirm RoHS compliance status with the manufacturer. Check for obsolescence notices as this component belongs to an older generation. Ensure ESD handling procedures are followed during assembly due to the sensitive CMOS technology used in the PSoC architecture.

Selection Notes

Select this part when an 8-bit MCU with integrated analog capabilities is required. It is suitable for designs needing CapSense integration without external components. Compare against CY8C21334 variants if higher memory capacity is needed. Consider pin count requirements carefully as the 20-pin package limits available GPIOs. Evaluate power consumption profiles against other PSoC 1 series options.

Part Context

This component belongs to the Infineon PSoC 1 CY8C21xxx series, designed for cost-sensitive mixed-signal applications. It combines digital logic with configurable analog blocks on a single chip. The series targets simple control tasks where analog signal processing and digital control must coexist efficiently within a compact footprint.

Replacement Considerations

CY8C21334-24PVXA offers increased memory resources while maintaining similar interface capabilities.
