W682310SG TR

Overview

The W682310SG TR is a microcontroller unit manufactured by Nuvoton Technology Corporation. It belongs to the NuMicro M252 series, which is built upon the Arm Cortex-M23 processor core. This component supports the Armv8-M instruction set architecture and operates at frequencies up to 48 MHz. It features an embedded memory configuration consisting of 256 KB of Flash and 32 KB of SRAM. The device is designed for industrial applications with a wide operating voltage range of 1.8 V to 5.5 V and a temperature range of -40 °C to 105 °C. Key technical attributes include low power consumption modes, programmable serial interfaces (PSIO), and hardware security features such as execute-only memory.

Feature Summary

• Integrates the Arm Cortex-M23 core with Armv8-M architecture support for efficient code execution.
• Includes Programmable Serial I/O (PSIO) hardware capable of generating diverse serial communication formats without high CPU load.
• Features Voltage Adjustable Interface (VAI) allowing direct connection to peripherals with varying voltage levels.
• Provides hardware-based code protection through Execute-Only-Memory (XOM) and unique identification numbers.

Applications

• Battery-powered Internet of Things (IoT) devices requiring extended operational life.
• LED lighting control systems utilizing specific serial protocols.
• Smart card readers and EEPROM interface applications.
• Industrial modules requiring robust anti-interference capabilities.

Procurement Notes

Verify the exact part number against official Nuvoton documentation to confirm the 'TR' suffix indicates tape-and-reel packaging. Ensure the specific variant matches the required memory size and package type. Cross-reference the datasheet for any recent revisions or pin-compatible alternatives within the M252 series to guarantee supply chain compatibility and functional equivalence during procurement.

Selection Notes

Select this model when an Armv8-M compliant MCU with low power characteristics is required. The M252 series is suitable for designs needing flexible serial communication via PSIO rather than standard UART/SPI alone. Consider the 1.8 V to 5.5 V input range for systems with variable power supplies. Evaluate the need for hardware security features like XOM if intellectual property protection is a priority for the application.

Part Context

This component is part of the NuMicro M252 family, which focuses on low-power IoT applications. The series distinguishes itself with the inclusion of PSIO and VAI, offering flexibility in peripheral integration. It sits alongside other M2x2 series parts but offers specific memory configurations and interface options tailored for cost-sensitive yet feature-rich embedded systems.

Replacement Considerations

Check for other members of the M252 series with different memory sizes or packages that may be pin-compatible. Verify if the M2354 series serves as a higher-performance alternative if additional security or processing power is needed, noting the architectural differences between Cortex-M23 and M23 cores.
