CMM-9304-V2.1
Bluetooth 4.2/5.0 compatible module
1.0
Description
The CMM-9304-V2.1 module is a miniaturised Bluetooth® Low Energy module based on EM
Microelectronic's low power fully integrated Bluetooth® low energy single-chip EM9304. Built in with a
highly efficient PCB antenna, this small sized, low cost module boasts one of the best power
consumption characteristics combined with outstanding Bluetooth Low Energy performances.
The flexible architecture of the EM9304 allows it to act as a companion IC to any ASIC or MCU-based
product, or as a complete System-on-Chip (SoC).
The module offers various possibilities of control via a simple SPI/UART interface: Host Controller
Interface (HCI) with the internal Bluetooth® v5.0 link layer; proprietary Application Controller Interface
(ACI) with the in-built Bluetooth® v4.2 stack, several profiles, and over-the-air firmware (FOTA)
updating routines.

Controller and Companion Modes of Operation Module as Controller (1 in figure below) The CMM-9304 module can be used with an external host where the user application and the host layers of the stack reside in the external processor or host controller.
- Page 4 CMM-9304-V2.1 C-MAX Bluetooth 4.2 / 5.0 compatible module SPI Slave Interface The CMM-9304 module has a Slave SPI to be used for the HCI (or ACI) transport layer. SPI Slave Features The SPI slave block supports following features: 4 wire SPI interface (SCK, CSN, MISO, MOSI) with flow control (RDY output signal).
- Page 5 CMM-9304-V2.1 C-MAX Bluetooth 4.2 / 5.0 compatible module • RDY at '0' buffer is not ready and byte cannot be written/read. SPI master has to wait until RDY is at '1'. After asserting CSN and before sending first byte SPI Master checks if RDY is at '1'.
- Page 6 CMM-9304-V2.1 C-MAX Bluetooth 4.2 / 5.0 compatible module SPI Slave Operation Start of the SPI transaction is as follows: 1. The SPI Master asserts CSN to '0', 2. Waits until RDY is at '1' 3. Sends 2 header bytes 4. Reads the status bytes STS1 and STS2.
