This BB1735-46 module is designed around Cypress ® CYW20735B1, a Bluetooth 5.0 compliant, 96 MHz CortexTM M4
core, ultra-low-power SoC. It has built in 2 MB ROM that stores Bluetooth stack and offloads flash usage. It has 384 KB RAM on chip to sustain large application code running. This module has integrated a 4 Mbit SPI flash to store the application code. This architecture provides a good flexibility for customers’s application code size expansion throughput Over-the-Air upgrading.
The ITON BB1735 Bluetooth module based on Cypress CYW20735 .The CYW20735 is a Bluetooth 5.0-compliant, stand-alone baseband processor with an integrated 2.4 GHz transceiver. Manufactured using the industry’s advanced 40 nm CMOS low-power process, the CYW20735 employs high levels of integration to minimize external components, reducing the device footprint and the costs associated with implementing Bluetooth solutions
