2 OVERVIEW
The Inventek Systems ISM14585-L35 SiP (System in Package), is the smallest, lowest
power and most integrated Bluetooth® 5.0 solution available. The ISM14585-L35
platform is the first BLE module from Inventek's FLEXiBLE product family. The
ISM14585-L35 SiP is an embedded wireless Bluetooth Low Energy (BLE) IoT radio,
based on the Dialog Semiconductor DA14585 radio SoC (System on Chip). The
ISM14585-L35 offers designers all the benefits of the industry-leading DA14580
technology but with even greater flexibility to create more advanced applications from the
smallest footprints and power budgets.
The ISM14585-L35 is ideal for applications such as remote controls, beacons, connected
sensors and innovative medical devices. Among the new features, the ISM14585-L35
supports Data Packet Length Extension, Link Layer Privacy v1.2, Secure Connections,
Bluetooth low energy and Efficient connectable Advertising.
The ISM14585-L35 integrated Audio Unit (AU) is equipped with a Pulse-Density
Modulation (PDM) interface that can be connected to up to 2 input devices (e.g. MEMS
microphones) or output devices, a PulseCode modulation (PCM) controller which
provides an up to 192 kHz synchronous interface to external audio devices, ISDN circuits
and serial data interfaces (I2S) and a 24-bit Sample Rate Converting unit (SRC) used to
convert the sampling rate of audio samples between the various interfaces. PDM and
PCM functionality can be mapped to any GPIO through the user programmable pin logic.
An integrated DMA controller handles all data transfers between the AU and the RAM
providing the CPU with the freedom to cope with other tasks.
The ISM14585-L35 SiP provide smarter, more flexible, and even lower power BLE
connectivity with an integrated 32bit CortexTM-M0 (16MHz), processor, an integrated
PMU (Power Management Unit), an integrated PA (Power Amplifier), an integrated
128kB of ROM, 64KB OTP, 1MB SPI Flash as well as a foot print compatible options for
an additional integrated 4Mb, 8Mb, or 16Mb of Flash.
The ISM14585-L35 SiP provides a number of features and standard peripheral interfaces
(see “Features” below), enabling a seamless connection to an embedded design. The
ISM14585-L35 is a very versatile SoC and is ideal for adding Bluetooth low energy to
products like remote controls, proximity tags, beacons, connected medical devices and
smart home nodes. The ISM14585-L35 supports all Bluetooth developments up to and
including Bluetooth 5.0.
The ISM14585-L35 also includes 96KB of RAM, the ISM14585-L35 has double the
memory for User applications of its predecessor to take full advantage of the standard’s
features. The ISM14585-L35 also includes an integrated microphone interface for voice
support at no additional cost. The wide supply voltage range (0.9 –3.6 V) covering a larger
choice of energy sources also enables full design flexibility.
