• The MAX32675C targets applications with mixed-signal requirements needed for industrial and medical sensors.
• The MAX78000 meets the emerging demand for intelligent edge devices.
Addressing connectivity Analog Devices’ MAX32655 microcontroller integrates a 100 megahertz (MHz) Arm Cortex-M4 with FPU, 512 kilobytes (Kbytes) of flash, 128 Kbytes of static random-access memory (SRAM) and 16 Kbytes of instruction cache to provide the effective combination of processor performance and memory storage required in typical
low-power applications. Beyond this processing subsystem, the device adds a comprehensive set of functional blocks for the security, power management, timing and digital and analog peripherals typically needed in asset tracking, wearables and healthcare monitoring devices (Figure 1). To meet the varied Bluetooth
connectivity requirements of diff erent applications, the MAX32655 provides dedicated hardware and soſt ware to support a complete set of Bluetooth 5.2 features. Along with a Bluetooth 5.2 radio, the microcontroller integrates a dedicated 32-bit RISC-V coprocessor
to handle timing-critical Bluetooth processing tasks. T is Bluetooth subsystem meets emerging performance demands, supporting 2 megabits per second (Mbits/s) high-throughput mode and a long-range mode with rates of 125 kilobits per second (Kbits/s) and 500 Kbits/s. Two device pins allow developers to simply connect an off -chip antenna in Bluetooth- enabled designs. Completing its Bluetooth 5.2 functionality and providing application support, the device’s run-time Bluetooth stack extends across the Arm Cortex-M4 with FPU, RISC-V and radio (Figure 2).

performance and memory requirements,
