Cortex M4 MCU 512 KB Flash
The NuMicro® M487 Ethernet series, specifically the product M487SIDAE, represents a new high-performance, low-power microcontroller. This is a cutting-edge device powered by the Arm® Cortex®-M4F core complete with DSP extensions, making it a powerful and versatile solution for a wide range of applications.
Function & Applications
The M487SIDAE can achieve speeds of up to 192 MHz, combined with a dynamic low power consumption of 175 µA/MHz. It's equipped with up to 160 KB of embedded SRAM, including a 32 KB cache to expedite the execution of external SPI Flash code. A 2 KB One-time Programmable ROM included functions for product life-cycle management.
Its diverse suite of functionalities makes it ideal for various applications including Industrial IoT, Smart Homes, IoT Gateway, and Serial-to-Ethernet Converters, to name a few.
Key performance parameters include a secure factory pre-loaded bootloader, which delivers Secure Boot functionality by checking the code integrity within the embedded Flash memory. The device also has a built-in Secure Protection ROM offering a safe space for storing confidential data and program-specific information.
Other key performance indicators include their unique Cryptography Accelerator, providing a range of features like ECC (P-521, B-571, K-571), AES-128, 192, 256, SHA, DES/3DES, HMAC and more. With these advanced capabilities, the device can address even the most advanced and secure systems' needs.
Package Types, Interface & Pin Configuration
M487SIDAE comes in a LQFP64 package type, further providing a host of interfaces such as up to 6 low power UART interfaces (17 Mbps), including 2 LIN interfaces. It offers up to 3 ISO-7816 interfaces, which can support full-duplex UART mode, and much more.
It also incorporates advanced Communication Interface, Control Interface, Analog Peripheral, and Advanced Connectivity options. This includes hardware like USB 2.0 high-speed device/host/OTG controller with on-chip PHY, and a robust 10/100 Mbps Ethernet MAC with RMII.
Reliability & Lifespan
This series, the M487SIDAE included, is designed for industrial-grade reliability. Its design is optimized for low power consumption, ensuring a longer operational lifespan. This is also aided by its robust operating temperature range of -40℃ to +105℃.
Further adding to its reliability factor is the large cache memory that speeds up code execution, along with the secure ROM functionality, safeguarding important data.
