Cortex M4 MCU 512 KB Flash
The M487KIDAE, under the M487 Ethernet Series by Nuvoton, is a high-performance, low-power microcontroller. It is powered by the Arm® Cortex®-M4F core with a DSP extension. M487KIDAE can reach a clock speed of up to 192 MHz while maintaining a dynamic low power consumption rate of 175 uA/ MHz.
Function and Applications
Aimed to facilitate industrial IoT, Smart Home technology, IoT Gateways, and Serial-to-Ethernet Converters, this microcontroller series embodies enhanced operational parameters. It has 512 KB zero-wait state flash memory and includes 32 KB cache to quicken the execution of external SPI Flash code. Additionally, it incorporates a pre-loaded bootloader providing secure boot functionality, which is instrumental for checking the code integrity in the embedded flash memory.
The M487KIDAE is impressively kitted with a wide range of features for optimal performance. The core runs up to 192 MHz, delivering 1.25 DMIPS per MHz with a memory protection unit (MPU). Its technology supports DST instruction set, and includes a cyclic redundancy calculation unit, an external bus interface, and RTC configured with 80 bytes of battery-powered backup registers. It is capable of performing ECC (P-521, B-571, K-571), AES-128, 192, 256, DES/3DES, SHA-160, 224, 256, 384, 512, HMAC, and features a random number generator.
Package Types, Interface & Pin Configuration
The M487KIDAE is available in an LQFP128 package type. It supports up to 6 low power UART interfaces (17 Mbps), including 2 LIN interfaces. Additionally, it features both USB 2.0 high speed device/host/OTG controller and full-speed device/host/OTG controller with on-chip PHY and a 10/100 Mbps Ethernet MAC with RMII.
