# EFR32BG27C320F768GJ39-B (Component) ## Description Bluetooth® 5.x Wireless SoC – 2.4 GHz wireless System-on-Chip (SoC) featuring an Arm® Cortex®-M33 processor for Bluetooth Low Energy (BLE), wearable devices, smart home products, industrial IoT, medical devices, and battery-powered embedded applications. Operates at up to 76.8 MHz with 768 KB Flash memory, 64 KB RAM, and a high-performance 2.4 GHz radio supporting Bluetooth 5.x, LE 2M PHY, LE Long Range, Bluetooth Mesh, and Direction Finding (AoA Transmitter). Features +4 dBm transmit power, −106.7 dBm receiver sensitivity, 19 GPIOs, DC-DC buck/boost converter, Secure Vault™ Mid security, AES hardware cryptography, TRNG, secure boot, and multiple communication interfaces including I²C, SPI, UART/USART, I²S, PWM, IrDA, and JTAG. Operates from a 1.71 V to 3.8 V supply, with 3.6 mA receive current and 4.1 mA to 11.3 mA transmit current, and is specified for operation over a −40°C to +85°C temperature range. Packaged in a compact 39-ball WLCSP (2.63 × 2.29 mm). The DigiKey-listed part is discontinued, with the -BR (Tape & Reel) version recommended as the replacement. #SiliconLabs #EFR32BG27C320F768GJ39B #EFR32BG27 #BluetoothSoC #WirelessMCU #CortexM33 #Bluetooth5 #BluetoothMesh #DirectionFinding #IoT #SecureVault #EmbeddedSystems ## Component Details - **Owner:** silicon-yard - **Created:** 7/27/2026 - **Last Updated:** 7/27/2026 - **Visibility:** Public - **Manufacturer Name:** Silicon Labs - **Datasheet URL:** https://storage.googleapis.com/graviton-electric-symbols/document_assets/user-uploaded/1522157e4d65e5734c3b27c7ecb8e538d51fecd88aa8b4f18a395f2180f1d056.pdf - **Package or Case Code:** WLCSP - **Symbol Style:** parametric-v1 - **Part Type:** Integrated Circuits - **Manufacturer Part Number:** EFR32BG27C320F768GJ39-B - **Part Type:** Integrated Circuits - **Sub-Type:** Logic - **Manufacturer:** Silicon Labs - **MPN:** EFR32BG27C320F768GJ39-B - **Mount Type:** Through Hole - **Package / Case Code:** WLCSP - **Pin Count:** 39 - **Logic Function:** AND ## Pins | Pin | Name | Type | |-----|------|------| | A1 | VREGSW | | | B4 | AVDD | | | A2 | VREGVDD | | | G2 | PAVDD | | | G5 | RFVDD | | | B1 | DECOUPLE | | | C1 | VBAT | | | B3 | IOVDD | | | A4 | DVDD | | | G6 | RESETN | | | C2 | BOOST_EN | | | D3 | PA04 | | | D5 | PC04 | | | E3 | PB02 | | | F1 | PA00 | | | B6 | PC02 | | | D6 | PC06 | | | D1 | PA02 | | | C5 | PC03 | | | C4 | PC00 | | | G1 | PB00 | | | B5 | PC01 | | | C3 | PA06 | | | E1 | PA01 | | | D2 | PA03 | | | D4 | PA05 | | | E2 | PB01 | | | A5 | PD01 | | | A6 | PD00 | | | C6 | PC05 | | | E6 | HFXTAL_O | | | F6 | HFXTAL_I | | | G3 | RF2G4_IO | | | E5 | VSS_2 | | | F3 | PAVSS | | | E4 | VSS_1 | | | A3 | VREGVSS | | | F4 | RFVSS | | | F2 | VSS_3 | | --- *Generated from [https://www.flux.ai/silicon-yard/efr32bg27c320f768gj39-b](https://www.flux.ai/silicon-yard/efr32bg27c320f768gj39-b)*
