BLE MODULE 
ISP1907 
1. Block Diagram
This module is based on nRF52 Nordic Semiconductor 2.4GHz wireless System on Chip (SoC) integrating 
a 2.4 GHz transceiver, a 32-bit ARM Cortex™-M4 CPU, either 512 kB or 192 kB flash memory, either 128 
kB RAM or 24 kB RAM and analog and digital peripherals. 
It can support BLE, ANT/ANT+, Thread, Zigbee and a range of proprietary 2.4 GHz protocols, such as 
Gazell from Nordic Semiconductor. 
Fully qualified BLE stacks for nRF52 are implemented in the S112/S132 SoftDevices which can be freely 
downloaded. ISP1907 can then be used in Central, Peripheral or both roles for BLE and for both ends of 
other  proprietary  protocols.  nRF52  platform  also  provides  extensive  software  support for  Zigbee  and 
Thread applications with nRF5 SDK, for ANT applications with S212/S312 SoftDevices. 
Ultra-low power consumption and advanced power management enables battery lifetimes up to several 
years on a coin cell battery. Despite its very small size 8 x 8 x 1.0 mm, the module integrates decoupling 
capacitors,  32  MHz  and  32.768  kHz  crystals,  DC-DC  converter  including  the  large  inductor, 
RF matching circuit and antenna in addition to the wireless SoC. 
Only  the  addition  of  a  suitable  DC  power  source  is  necessary  for  low  energy  connectivity.  Sensor 
applications require the further addition of appropriate sensors. The antenna was designed to be optimized 
with several standard ground plane sizes. When NFC function is available, the NFC tag antenna can be 
connected externally. 
Specification subject to change without notice.
