Built-in ARM^® Cortex^®-M4F 32-bit micro-processor, supporting floating-point operation

• Maximum frequency: 64 MHz
• Power consumption: 30 µA/MHz

Memory

• 256 KB RAM with retention (four 8 KB banks and seven 32 KB banks) for GR5515 series SoCs, and 128 KB RAM with retention (four 8 KB banks and three 32 KB banks) for the GR5513 SoC

Power Management

• On-chip DC-DC Converter
• On-chip I/O LDO to provide I/O voltage and supply external components
• Power supply voltage: 1.7 V ~ 3.8 V
• I/O voltage: 1.8 V ~ 3.3 V (typical value)
