M481SIDAE

Introduction

The NuMicro® M481 Base series, developed by Nuvoton, envelops the M481SIDAE, a high performance, low power microcontroller. Empowered by Arm® Cortex®-M4F core with DSP extension, it operates at a frequency up to 192 MHz with an impressive 175 uA/ MHz dynamic low power consumption. The M481SIDAE is designed for multiple applications, including IoT Devices, Data Collectors, among others.

Function & Applications

The MCUs in the M481 Base series come with an embedded Flash memory of 512 KB/256/128 KB and an embedded SRAM of 160/128/64 KB. The factory pre-loaded bootloader offers Secure Boot functionality that executes a code integrity check in embedded Flash memory. The inbuilt Secure Protection ROM provides a secure area for protecting confidential program or data in line with OTA firmware upgrade. The One-Time Programmable ROM included ensures effective product life-cycle management.

Performance Parameters

The product holds a lot of prominent specifications, such as DSP instruction set, Memory Protection Unit (MPU), 4 KB Secure Protection ROM, and 2 KB One-Time-Programmable ROM. It has also endowed with several in-built clock features like 4 to 24 MHz crystal oscillator, 32 kHz oscillator for RTC, internal 12 MHZ RC oscillator, etc., and a set of peripherals, such as UART, SPI, I2C, and PWM.

Package Types, Interface & Pin Configuration

The M481SIDAE is packaged in an LQFP64 type. It is equipped with high-speed peripheral interfaces like UART, SPI, I2C, and PWM.

Reliability & Lifespan

The device operates over an industrial temperature range of -40 ℃ to 105 ℃, proving its versatility and robustness in varying conditions. Its low power consumption and advanced power management capabilities maximize its lifespan.

Standards & Certifications

The device adheres to necessary industrial standards and certifications, though the exact details of these must be gathered directly from the manufacturer, Nuvoton.

Application Cases & Reference Designs

While specific Application Cases and Reference Designs are proprietary to Nuvoton, the specification characterizes its viability in IoT Device and Data Collector applications. For explicit application cases and design references, one should reach out directly to Nuvoton.
