- ARM®
Cortex®-M4F 32-bit micro-processor with floating point support
- Maximum frequency: 64 MHz
- Power consumption: 30 µA/MHz
- Memory
- 256 KB RAM with retention (four 8 KB RAM blocks and seven 32 KB RAM blocks) for GR5515 series SoCs, and 128 KB RAM with retention (four 8 KB RAM blocks and three 32 KB RAM blocks) for the GR5513 SoC
- 1 MB Flash for GR5515 series SoCs and 512 KB Flash for the GR5513 SoC (exceptions: GR5515I0ND/GR5515I0NDA requiring external QSPI Flash and GR5515IENDU requiring 512 KB embedded Flash)
- Power management
- On-chip DC-DC Converter
- On-chip I/O LDO to provide I/O voltage and supply external components
- Supply voltage: 1.7 V to 3.8 V. The supply voltage of GR5515I0ND/GR5515I0NDA (when the external Flash of GR5515I0NDA supplied by high voltage) shall equal the working voltage of external QSPI Flash
- I/O voltage: 1.8 V to 3.3 V (Typical) (for GR5515I0ND/GR5515I0NDA/GR5515IENDU/GR5513BENDU Flash using high voltage, the VIO_LDO_OUT shall be connected to VBATL in schematic circuit.)
- OFF mode: 0.15 µA (Typical); nothing is on except VBAT, chip in reset mode
- Ultra deep sleep mode: 0.65 µA (Typical); I/O LDO off, no memory retention; woken up by AON GPIO or AON Timer
- Sleep mode: 1.3 µA (Typical) when I/O LDO and BOD/BOD2 turned off, lowest voltage level for memory retention, and 32 KB memory retention; woken up by AON_RTC, AON GPIO, or Bluetooth LE Event
