CY8C4246AZI-M475

Overview

The CY8C4246AZI-M475 is an ARM Cortex-M0 microcontroller from the PSoC 4200M series, housed in a TQFP-64 package. It features 64 kB of Flash program memory and 8 kB of SRAM data RAM. The device operates with a maximum clock frequency of 48 MHz and supports a supply voltage range of 1.71 V to 5.5 V. Key peripherals include one 12-bit SAR ADC, two low-power comparators, four Serial Communication Blocks (SCB), and eight TCPWM modules. It provides 51 general-purpose I/O pins and supports interfaces such as I2C, SPI, and UART.

Feature Summary

• Integrates programmable analog blocks including a 12-bit SAR ADC and dual comparators for signal conditioning.
• Includes multiple serial communication blocks supporting standard protocols like I2C, SPI, and UART.
• Features eight Timer/Counter/PWM modules for precise timing and waveform generation tasks.

Applications

• General-purpose embedded control systems
• Sensor interface circuits requiring analog-to-digital conversion
• Industrial automation controllers

Procurement Notes

Verify the specific ordering suffix M475 to confirm the TQFP-64 package and commercial temperature range. Ensure compatibility with the required pin count and memory configuration for the target design. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement plans.

Selection Notes

Select this component when a balance of moderate flash memory and versatile analog capabilities is required. The 48 MHz processing speed suits applications needing efficient code execution without high power consumption. Verify that the 51 available I/O pins meet the system connectivity requirements.

Part Context

This part belongs to the Infineon PSoC 4200 family, designed for cost-sensitive applications requiring mixed-signal integration. The CY8C4246 variant specifically offers 64 kB of non-volatile memory, distinguishing it from higher-capacity models in the same series while maintaining the core Cortex-M0 architecture.

Replacement Considerations

Check for CY8C4246AZI-L445 or CY8C4246AZS-M475 if different packaging or temperature ratings are needed. Verify pinout compatibility before substituting with other PSoC 4 devices.
