Nordic Semiconductor has publicizes an addition to its nRF54 Sequence, its fourth technology of Bluetooth Low Vitality Methods-on-Chip (SoCs). The nRF54L Sequence is the logical successor to the nRF52 Sequence, a product household that has seen a number of billion SoCs delivered to 1000’s of shoppers since its introduction in 2015. The primary SoC within the nRF54L Sequence, the nRF54L15, is suited to the following technology of wi-fi Web of Issues (IoT) merchandise. The SoC targets medical/healthcare, good dwelling, industrial IoT, VR/AR, PC equipment, distant controllers, gaming controllers and a number of different IoT functions. The nRF54L Sequence enhances the not too long ago introduced nRF54H Sequence. Whereas the nRF54L Sequence has huge applicability from high-volume merchandise to extra superior units, the nRF54H Sequence possesses the processing energy and enormous capability reminiscence wanted for IoT merchandise.
“With the nRF54L Sequence, Nordic reinforces its place because the world’s main Bluetooth LE firm and a frontrunner in low energy wi-fi IoT applied sciences generally,” says Svenn-Tore Larsen, CEO, Nordic Semiconductor. “The corporate’s low energy wi-fi engineering crew is without doubt one of the finest on the planet and, backed by an unwavering dedication to R&D funding, Nordic has as soon as once more redefined what’s doable with the know-how. The brand new collection will enable 1000’s of shoppers to markedly elevate the efficiency and lengthen the battery lifetime of their end-products whereas developing with much more revolutionary designs.”
Manufacturing Flexibility
The nRF54L Sequence encompasses a {hardware} structure fabricated utilizing TSMC’s 22ULL (22 nm) course of know-how. The nRF54H Sequence is fabricated utilizing the GlobalFoundries 22FDX (22 nm) course of. By investing in two wafer suppliers, Nordic will increase the pliability of its provide chains.
“We have now gained helpful insights from the challenges posed by COVID-19. By strategically leveraging two distinct manufacturing amenities positioned in several areas, we’re dedicated to enhancing provide chain diversification for the last word advantage of our prospects and their danger mitigation efforts,” says Geir Langeland, EVP gross sales & advertising, Nordic Semiconductor.
The nRF54L15 SoC options an Arm Cortex-M33 processor working at 128 MHz. The processor offers double the processing energy of the nRF52840 SoC whereas decreasing energy consumption. Processing is supported by 1.5 MB of non-volatile reminiscence and 256 KB of RAM, ample for concurrent working of a number of protocols.
“Our nRF52 Sequence SoCs are the world’s most offered Bluetooth LE units and it’s about time we step it up once more to cowl at this time’s and tomorrow’s functions,” says Kjetil Holstad, EVP product administration, Nordic Semiconductor. “With the nRF54L15 we ship what’s anticipated by a contemporary Bluetooth LE SoC, with elevated efficiency and reminiscence, and lowered energy consumption making it a future-proof alternative to your wants.”
Safety and Future-Proofing in IoT
Given the rising significance of safety in IoT, the nRF54L15 SoC incorporates {hardware} and software program safety features guaranteeing its readiness for the following technology of IoT. It’s designed for PSA Licensed Degree 3. The SoC gives safety companies resembling Safe Boot, Safe Firmware Replace and Safe Storage. Built-in tamper sensors can detect assaults and take protecting motion, whereas the cryptographic accelerators are hardened in opposition to side-channel assaults.
The nRF54L15 encompasses a multiprotocol radio that gives as much as +8 dBm TX energy (with 1 dB increments) with -98 dBm RX sensitivity for 1 Mbps Bluetooth LE. The radio features a new 4 Mbps knowledge charge choice for two.4 GHz proprietary protocols, with improved throughput, effectivity, and latency. It helps all Bluetooth 5.4 options, Bluetooth Mesh, Thread, and Matter. The radio can be geared up to help future Bluetooth specification updates.
Enhanced Vitality Effectivity
The radio energy consumption improves in TX and RX in contrast with the nRF52 Sequence. For instance, in contrast with nRF52840 SoC, the radio RX present is halved (working from a 1.8 V DC provide), leading to power financial savings and permitting for compact batteries or prolonged battery life.
Additional power financial savings come from a brand new International RTC (real-time clock) peripheral that may get up the SoC from its sleep mode, eradicating the necessity for an exterior RTC and decreasing energy consumption for functions sleeping for lengthy durations. This characteristic can allow multiyear battery life for sure merchandise.
The nRF54L15 is now out there for sampling in a 6 by 6 mm QFN bundle with 31 basic goal input-outputs (GPIOs). The SoC can be out there in two 2.4 by 2.2 mm wafer-level chip scale packages (WLCSPs) with 32 GPIOs (300 µm pitch) and 14 GPIOs (350 µm pitch). These WLCSPs are greater than 50% smaller than the nRF52840 WLCSP.
