Insight SIP Expands BLE Module Series With Power and Memory Variants

Insight SIP has expanded its ISP2454 Bluetooth Low Energy (BLE) module series to include three distinct variants in response to customer feedback following the initial launch of the ISP2454-LX. The company reports strong interest and demand for the module, which is based on Nordic Semiconductor’s nRF54L15 chip, and has developed additional configurations to address differing use case requirements.

Pin-Compatible Variants Enable Design Flexibility

All three variants in the ISP2454 series share the same nRF54L15 core radio and processor, along with an integrated antenna. The variants maintain pin and footprint compatibility, allowing manufacturers to build product variants with different characteristics without redesigning carrier boards. The modules are also pin-compatible with Insight SIP’s previous generation ISP15, ISP18, and ISP19 series BLE modules, providing an upgrade path for existing equipment to adopt the latest generation of Bluetooth technology.

The ISP2454-LL serves as the series’ entry-level model while still offering a fully integrated solution that requires no external components for over-the-air radio connectivity. This variant omits the fine-timing crystal operating at 32 kHz, which optimizes power consumption. According to Insight SIP, this configuration suits applications without significant limitations on power supply, such as mains-connected equipment, or where power consumption is dominated by components that consume more power than the BLE module itself, including cellular radios or large processors.

Power and Memory Optimization

The series’ ISP2454-LX variant is a fully integrated device with all power-saving features, notably including the 32 kHz timing crystal. Insight SIP positions this configuration as suitable for a wide range of applications, offering state-of-the-art performance in processing, radio capability, and low power consumption.

The ISP2454-LP variant adds a substantial 4 MB flash memory on top of the series’ standard features. Insight SIP specifically targets this configuration for customers with large, complex applications, which may occupy the majority of the standard 1.5 MB nonvolatile memory. The additional memory serves dual purposes: it can handle over-the-air application updates with rollback capability in case of update problems, and it accommodates applications with large local data storage requirements, particularly when the BLE module experiences long intervals between transmitting data to cloud systems or other infrastructure.

Addressing Market Demands

The expansion from a single module to three variants reflects Insight SIP’s response to market feedback and varying customer requirements. By maintaining complete pin compatibility across all variants while differentiating on power optimization and storage capacity, the company enables engineers to select appropriate configurations without sacrificing board design flexibility or requiring custom module development.

The modular approach allows product developers to start with one variant during prototyping and switch to another during production based on actual power budget analysis or feature requirements. Backward compatibility with previous-generation modules further reduces development risk for companies upgrading existing product lines to incorporate newer Bluetooth specifications and the nRF54L15’s enhanced capabilities.

Advancing BLE Solutions

The ISP2454 series targets applications in industrial IoT, medical devices, secure entry systems, smart home and smart city infrastructure, and fitness and health monitoring devices. The three-variant strategy provides engineers with configuration options that balance power consumption requirements, memory capacity needs, and cost constraints without compromising the integrated antenna performance or compact 8.0 mm × 8.0 mm form factor. 

Insight SIP’s release acknowledges that while some applications prioritize extended battery life through optimized sleep currents, others require additional storage for sophisticated protocol stacks or local data buffering, and still others operate in power-abundant environments where simplified designs reduce system cost.
