Goodix GR5513BEND

ARM Cortex-M4, 64 MHz, 512 kB ROM, 128 kB RAM

The Goodix GR551x family is a single-mode, low-power Bluetooth 5.1 System-on-Chip (SoC). It can be configured as a Broadcaster, an Observer, a Central, and a Peripheral and supports the combination of all the above roles, making it an ideal choice for Internet of Things (IoT) and smart wearable devices.Based on ARM Cortex-M4F CPU core, the GR551x integrates low-power Bluetooth 5.1 protocol stacks, a 2.4 GHz RF transceiver, on-chip programmable Flash memory, RAM, and multiple peripherals.
