What are the key features of EFM8UB10F16G-C-QFN20?
- Full-speed USB 2.0 device interface integrated on-chip enables direct USB connectivity without an external bridge IC
- 50 MHz CIP-51 8051 core with 16 KB Flash and on-chip SRAM delivers fast instruction throughput for real-time embedded tasks
- 3x3 mm QFN-20 package with only 20 pins reduces PCB footprint while maintaining access to GPIO, timers, and serial interfaces
What is EFM8UB10F16G-C-QFN20 used for?
The EFM8UB10F16G-C-QFN20 is ideal for compact USB peripheral designs such as HID devices, CDC virtual COM ports, and custom USB data loggers where a small 3x3 mm 20-pin package is required. Its 50 MHz 8051 core and 16 KB Flash make it suitable for firmware-controlled USB protocol stacks in consumer electronics, laboratory instruments, and industrial handheld devices. The integrated full-speed USB 2.0 engine eliminates the need for an external USB controller, reducing BOM cost and board complexity in battery-powered USB gadgets and sensor nodes.

Frequently Asked Questions
What USB standard does the EFM8UB10F16G-C-QFN20 support natively, and what data rates does that enable?
The EFM8UB10F16G-C-QFN20 integrates a full-speed USB 2.0 device interface, supporting data rates up to 12 Mbps without any external USB bridge IC. The on-chip USB engine handles enumeration, endpoint management, and data transfer, freeing the 50 MHz CIP-51 8051 core to execute application firmware. This makes the device well suited for HID keyboards, mass storage interfaces, and CDC virtual serial port designs.
How does the 3x3 mm QFN-20 package of EFM8UB10F16G-C-QFN20 compare to larger 8051 packages for space-constrained PCB designs?
The 3x3 mm QFN-20 footprint of the EFM8UB10F16G-C-QFN20 occupies roughly 9 mm² of board area, compared to 25–50 mm² for SOIC-20 or TSSOP-20 packages. With 20 pins providing access to USB D+ and D- lines, multiple GPIO, SPI, I2C, and UART, the compact package is optimal for wearable devices, USB dongles, and embedded sensor nodes where every square millimeter of PCB space carries a cost premium.
What Flash and RAM capacity does EFM8UB10F16G-C-QFN20 offer, and is it enough for a typical USB HID firmware stack?
The EFM8UB10F16G-C-QFN20 provides 16 KB of on-chip Flash program memory and sufficient on-chip SRAM for a compact USB HID or CDC firmware stack running at 50 MHz. A typical USB HID keyboard or mouse firmware requires 4 KB to 10 KB of Flash, leaving headroom for application logic within the 16 KB budget. The 50 MHz CIP-51 core executes standard 8051 instructions with high throughput, enabling responsive USB polling intervals of 1 ms.
