Block Diagram
The block diagram of GR5526 is shown in the figure below.
- Bluetooth subsystem
- A 2.4 GHz transceiver and a digital communication core that supports Bluetooth 5.3
- MCU subsystem
- An ARM® Cortex®-M4F with all the required memories and peripherals
- Security cores that can be used for application security and secure boot implementation
- GPU + DC to enhance processing capabilities
- Power management unit (PMU) subsystem
- All the required power management modules to supply sufficient power for both internal modules and external peripherals
- Modules required for ultra-low-power operation are in standby mode. HFRC_192M, RNG_OSC, LFRC_32K, wakeup GPIOs (Wake up), low-power comparator (LP Comp.), and power state controller (Power Sequencer) are used to control the state of different modules
