CY8C4247AZS-M475

Overview

The CY8C4247AZS-M475 is an ARM Cortex-M0 microcontroller within the PSoC 4200M series, manufactured by Infineon Technologies. It features a 128 kB Flash program memory and 16 kB SRAM data RAM. The device operates with a maximum clock frequency of 48 MHz and provides 51 general-purpose I/O pins. It includes a 12-bit SAR ADC capable of 1 MSPS sampling rate, four SCB modules, eight TCPWM blocks, two LP comparators, and eight DMA channels. The unit supports a supply voltage range of 1.71 V to 5.5 V and functions within a temperature range of -40°C to +105°C.

Feature Summary

• Integrates programmable analog and digital blocks for flexible system design
• Includes low-power comparators and timer/PWM modules for signal processing
• Supports multiple serial communication interfaces via configurable blocks

Applications

• General-purpose embedded control systems
• Industrial automation controllers
• Consumer electronics devices

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead times prior to ordering. Ensure packaging specifications match assembly requirements. Check for end-of-life notifications as availability may be limited.

Selection Notes

Select this model when a Cortex-M0 core with integrated programmable analog resources is required. Consider the 128 kB Flash capacity and 51 GPIO count for moderate complexity designs. Evaluate power consumption against the 1.71 V to 5.5 V operating range for battery-powered applications.

Part Context

This component belongs to the PSoC 4200M family, designed for cost-sensitive applications requiring mixed-signal capabilities. It utilizes the TQFP-64 package for surface-mount installation. The architecture combines a standard ARM processor with configurable peripheral blocks to reduce external component count.

Replacement Considerations

Check for pin-compatible alternatives within the same PSoC 4 series if inventory is unavailable. Verify that substitute parts maintain identical Flash size, GPIO count, and package dimensions.
