Overview
The CY8C21312-12PVXE is an 8-bit microcontroller from the Cypress PSOC 1 family, utilizing the M8C core. It features 8KB of in-system programmable flash memory and 512 bytes of RAM. The device operates at a maximum clock speed of 12MHz with an internal oscillator. It supports a supply voltage range of 3V to 5.25V and includes communication interfaces such as I2C, SPI, and UART/USART. The component is housed in a 20-SSOP package and is rated for an operating temperature range of -40°C to 85°C.
Feature Summary
- Integrates programmable analog and digital blocks within a single chip architecture
- Supports in-system programming via standard serial interfaces
- Includes built-in low voltage detect and power-on reset peripherals
Applications
- Consumer electronics requiring mixed-signal processing
- Industrial control systems with sensor interfacing needs
- Battery-powered devices utilizing low power modes
Procurement Notes
Verify the specific suffix '12PVXE' against official Cypress documentation to confirm the 12MHz speed grade and commercial temperature range. Ensure compatibility with PSOC Designer software versions used for development. Confirm RoHS compliance status through the manufacturer's current certificate of conformity before finalizing procurement orders.
Selection Notes
Select this component when an 8-bit MCU with integrated analog capabilities is required. The 12MHz speed offers a balance between performance and power consumption. Consider the 20-SSOP package constraints for PCB layout. Evaluate if the 8KB flash capacity meets application firmware requirements compared to higher-density variants in the CY8C21xxx series.
Part Context
This part belongs to the PSOC 1 CY8C21xxx series, designed for cost-sensitive applications needing analog-digital integration. It replaces older discrete solution designs by combining CPU, memory, and programmable interconnects on one die.
Replacement Considerations
Check for CY8C21312-24PVXA for higher speed requirements or CY8C21312-12PVXA for identical specifications with potential packaging differences. Verify pinout compatibility before substitution.
