M0516LAN

Microcontrollers Overview

The Nuvoton M0516LAN is a 32-bit microcontroller from the NuMicro M051 series, featuring an ARM Cortex-M0 core operating up to 50 MHz. It includes 64 KB of APROM, 4 KB of SRAM, 4 KB of DataFlash, and 4 KB of LDROM. The device supports a wide operating voltage range of 2.5 V to 5.5 V and functions within a temperature range of -40°C to +85°C. Connectivity options include two UARTs, two SPIs, one I2C, four 32-bit timers, eight PWM outputs, and an 8-channel 12-bit ADC. It is housed in a 48-pin LQFP package.

Microcontrollers Feature Summary

• Integrates multiple communication interfaces including UART, SPI, and I2C with master/slave capabilities.
• Features a built-in Low Dropout Regulator (LDO) enabling operation across a wide voltage range.
• Includes hardware debugging support via Serial Wire Debug (SWD) interface.

Microcontrollers Applications

• Industrial control systems
• Security and alarm devices
• Temperature sensor applications

Microcontrollers Procurement Notes

Verify the specific ordering suffix 'LAN' corresponds to the required package type (LQFP-48) and operating temperature range (-40°C to +85°C). Confirm that the component status aligns with current design requirements, as availability may vary. Ensure compatibility with existing development tools such as the NuTiny-SDK-M051 for validation purposes.

Microcontrollers Selection Notes

Select this model when 64 KB of program memory is required alongside extensive peripheral connectivity. The LQFP-48 package provides higher pin counts compared to QFN variants, suitable for complex board layouts. Consider the 50 MHz processing speed and rich interface set for applications demanding robust serial communication and precise analog-to-digital conversion.

Microcontrollers Part Context

This component belongs to the NuMicro M051 series, which also includes the M052, M054, and M058 families. These microcontrollers share the same ARM Cortex-M0 core architecture but differ in memory sizes and pin configurations. The M0516 variant specifically offers double the flash memory of the base M052 models while maintaining similar peripheral sets.

Microcontrollers Replacement Considerations

Compatible substitutes within the same family include the M0516ZAN, which features identical specifications but utilizes a 33-pin QFN package instead of LQFP-48. Designers must account for pinout differences and footprint changes when transitioning between these package types.

Microcontrollers FAQ

Does the M0516LAN support external memory expansion?

Yes, the device includes an External Bus Interface (EBI) that allows access to external memory-mapped devices, supporting 64 KB in 8-bit mode or 128 KB in 16-bit mode.

What clock sources are available for the system?

The microcontroller supports both an external high-speed crystal oscillator (4~24 MHz) and an internal high-speed oscillator (22.1184 MHz) with trimmed accuracy.
