Bluetooth module includes DC-DC converter and crystals

September 19, 2018 // By Julien Happich
The ISP1507-AL ultra-miniature Bluetooth module from Insight SiP is based on the class-leading Nordic Semiconductor nRF52 series, offering a 32 bits ARM Cortex M4 CPU with floating point processor, 192 kB flash memory, 24 kB RAM, a complete set of 13 IOs, analog and digital peripherals SPI, I2C and GPIO.

Combined with its integrated 32 MHz / 32 Khz crystals, RF antenna and matching circuit and DC-DC convertor, this module forms a standalone Bluetooth Low Energy node. 

This Bluetooth 5.0-ready module is the smallest on the market at only 8- x 8-mm, claims Insight SiP, with a thickness less than 1mm. Despite the significant computing power on offer, power consumption is even lower than previous generations, drawing only 5.8mA for transmission, and reception, 0.8µA for standby mode and 0.3µA for deep sleep mode. Advanced power management enables battery lifetimes up to several years on a coin cell battery. Transmission output power reaches +4 dBm and reception sensitivity is also improved to -96 dBm. The ISP1507-AL module is well suited for mesh relay nodes and price sensitive solutions and suitable for IoT, wearable, industrial sensor and home network applications.
