　　The MAX32600 microcontroller is based on the industry-standard ARM® Cortex®-M3 32-bit RISC CPU operating at up to 24MHz. It includes 256KB of flash memory, 32KB of SRAM, a 2KB instruction cache, and integrated high-performance analog peripherals.

　　The MAX32600 is available in the following package options: 192-ball, 12mm x 12mm CTBGA; 120-ball, 7mm x 7mm CTBGA; and 108-ball, 5.4mm x 4.3mm WLP.

　　In addition to the free tools provided by Maxim, the MAX32600 supports the Embedded Workbench from IAR. The IAR Embedded Workbench® incorporates a compiler, an assembler, a linker, and a debugger into one IDE. It is easy to use, provides advanced and highly-efficient optimization features, and is highly integrated with hardware, RTOS products, and middleware. The IAR Embedded Workbench for ARM is available in several versions, including a product package that is designed specifically for ARM Cortex-M core families.
