Frequently Asked Questions
What processor core and clock speed does the IS1871SF202 integrate?
The IS1871SF202 integrates an ARM Cortex-M0 core clocked at up to 16 MHz, paired with up to 256 KB of flash memory and 32 KB of SRAM to support on-chip firmware and sensor data processing in a single-chip BLE solution.
How low is the sleep current of IS1871SF202, and why does it matter for battery-powered designs?
The IS1871SF202 achieves a sleep current below 1 µA in its deepest power-saving mode. This enables years of operation from a standard 230 mAh coin cell battery when the device wakes briefly every second to transmit BLE advertisement packets in IoT sensor applications.
Which supply voltage range does the IS1871SF202 support, and what BLE version does it implement?
The IS1871SF202 operates from a 1.8 V to 3.6 V supply rail and implements Bluetooth Low Energy 5.0, delivering a 2.4 GHz receive sensitivity of approximately -93 dBm for reliable wireless links across distances up to 100 meters in open environments.
For a wearable fitness band design, is the IS1871SF202 QFN package practical?
Yes. The IS1871SF202 is housed in a compact Quad Flat No-Lead (QFN) package measuring roughly 5 mm x 5 mm, making it practical for space-constrained wearable PCB layouts where minimizing board area while retaining 2.4 GHz antenna clearance is critical.
